Qt3d_chess_Ring

[عزالدين رمال‎]

Hello Mahmoud

  I'm working on building a 3D chess game with a library QT3D but there are missing functions

Can you add the function 

unproject (const QMatrix4x4 &modelView, const QMatrix4x4 &projection, const QRect &viewport) const   to the class QVector3D

Perhaps a good example of using a class Qt3D

Hello Mahmoud

Thank you so much

[عزالدين رمال‎]

Hello Mahmoud and everyone

This is what I have achieved so far

The game is not working properly I need some help

I hope iller and Bert can help me fix it

[Bert Mariani]

Hello Ezzedine

First ... Very impressive 3D display of the Board and Chess Pieces !!!

Next step:

Ignore the "Rules" for now.

Try to move a Piece from a  Source square to a Destination square.

Empty out the Source square, draw Piece on Destination square

     Or -  Redraw the All Pieces to their New Position.

[عزالدين رمال‎]

Hi Bert

Another problem is the mismatch between the board matrix and the distribution of chess pieces 

If you have a little time, help me

I tried to flip the matrix but that doesn't work

board = [

['R', 'P', ' ', ' ', ' ', ' ', 'p','r'],

['N', 'P', ' ', ' ', ' ', ' ', 'p','n'],

['B', 'P', ' ', ' ', ' ', ' ', 'p','b'],

['K', 'P', ' ', ' ', ' ', ' ', 'p','k'],

['Q', 'P', ' ', ' ', ' ', ' ', 'p','q'],

['B', 'P', ' ', ' ', ' ', ' ', 'p','b'],

['N', 'P', ' ', ' ', ' ', ' ', 'p','n'],

['R', 'P', ' ', ' ', ' ', ' ', 'p','r']

]

[عزالدين رمال‎]

Hello Mahmoud

Why can't I access the object defined inside a conditional statement except within it?

  if piece = 'k' or piece = 'K'

 oking = new Model3d(oPieceEntity, oking, "models/king.obj")

oking.setModelpos(i*17-75, 0, (7-j)*17-42)

oking.setmodelSiz(0.17, 0.18, 0.17)

// oking.removeComponent()

// White piece.

if ascii(piece) < 96

oking{

SetModelTexture("textures/WhitePiece.jpg")

setModelDirection( 0, 1, 0, 90)

}

if selectionI = i and selectionJ = j

oking{

SetModelTexture("textures/WhitePieceCliked.jpg")

}

ok

// Black piece.

else

oking{

SetModelTexture("textures/Black Piece.jpg")

setModelDirection( 0, 1, 0, 270)

}

if selectionI = i and selectionJ = j

oking{

SetModelTexture("textures/BlackPieceCliked.jpg")

}

ok

ok

When trying to access the object from someone else inside the function it returns an error that it is not defined

[عزالدين رمال‎]

Hello Mahmoud and everyone

Another note, there is a memory leak, the application runs smoothly, when I open the task manager in Windows 10, there are alerts that send errors to Microsoft

[Ilir]

Hello,

I can confirm memory leak. However, I don't see any alerts reported on Windows 10 Pro 64 bit.

Regarding object access: it can be accessed after it is created. Keep in mind: Ring is dynamically, not statically typed language. In above example, oking object becomes available if piece = 'k' or piece = 'K'.

[عزالدين رمال‎]

Hello iller

For memory, I call the display function, which every time produces new entities and is not deleted

I'll try to fix it by deleting the old entities before calling the view function.

I want to use  QSkyboxEntity   and I can't find examples except in Qml .

 If you can, or one of the team members can give us an example of their use

Thank

[عزالدين رمال‎]

Hello Mahmoud

I wrote this function to delete entity components, but it doesn't work properly and terminates the program

//---------------------Use-------------------------------

// entity = new QEntity(.......)

//DeleteEntityRecursively(entity)

//---------------------------------------------------

 func DeleteComponentRecursively(Entity)

                        ComponentsToDelete = Entity.Components()

                                           for Component in ComponentsToDelete

                                                            Entity.removeComponent(Component)

                                                          Del(ComponentsToDelete, Component)

                                                            Component = Nullpointer()

                                            next

                           ChildrenNodes = Entity.ChildNodes()

                                              for ChildNnode in ChildrenNodes

                                                               del(ChildrenNodes, childNode)

                                              next

                          entity = nullpointer()

I tried to use #    oPieceEntity.deleteLater()   #   but it permanently deletes the entity from memory

[عزالدين رمال‎]

Hello Mahmoud and everyone

I made a handmade skybox waiting for the trumpet  QSkyboxEntity 

when using

 oForwardRenderer = oView.defaultFrameGraph()

oForwardRenderer{

setClearColor(new QColor() { setrgb(000,204,000,255) })  This works

setFrustumCullingEnabled(false)   This does not work

setGamma(2.5) This does not work

}

I want to stop Frustum Culling to be able to enlarge the cube in QT document in class QskyboxEntity  this is required

file on google drive

[عزالدين رمال‎]

[Bert Mariani]

Hello Ezzadine

Made these changes to try to understand your code

SetModelTexture("textures/BlackPiece.jpg")  <<<  removed space in "Black Piece.jpg"

Do the same in your jpg name.

Global definition for the degree of tilt

   degreeW = 45       //  90

   degreeB = 45 +180  // 270

The tilt of the wooded board and the tile shows opposite directions ??!!

See screen capture

Removed all the "elseif"  for the Piece drawing to simplify the look

Just using  if..ok  to match a piece.

Added "SEE" to show  tile that was clicked on.

Get wrong position I-J being reported every 2nd tile.

Attached modified file -- QD3d_Chess.ring.txt   (remove .txt after download)

In your display ... please remove the "Event i:5 and j:7 .."  --- too messy looking

Add it to the top title bar for readability  

Note:

White pieces go on the bottom of the board

Black pieces go on the top of the board.

[Ilir]

Hello,

it seems setting frustum culling flag works (only?) for QSkyboxEntity.

You don't have to worry about it, just change your camera far plane position from 1000 to 10000 for example.

[Bert Mariani]

More readable when displayed in 3D screen

func mouseInput(i,j)

....

   oText3d.setText3D("IJ: " +i +"-"+ j + " B: " + board[i][j] )

Main problem with the 3D is that the Mouse Click does not give the proper I-J co-ordinate

[Bert Mariani]

Observation:

The White and Black Knights face different directions when these values are used !!

Board and Tile also point id different directions ??

   degreeW = 30      //  90

   degreeB = 210     // 270

[Bert Mariani]

   degreeW = 30      //  90

   degreeB = 210     // 270

[عزالدين رمال‎]

Hello Bert and ilir

Thanks Burt for the great advice, I will study the attached code and try to use it

As for the determination QObjectPicker   it is not very accurate and determines what is under the cursor by about half a centimeter

There is a lot missing from the ring, mouse control, animation..etc.

  I hope Mahmoud will add it in future releases

  The problem in transplanting the plate is opposite to the transplanting of cutting

Although the implant is based on the matrix board[][]

By me ###oText3d.setText3D ( "IJ:" + i + "-" + j + "B:" + board [i] [j])###   this is for tracking errors and it will be removed in the end

========================================================

 oboard = new Model3d(oRootEntity, oboard, "models/board.obj"){

setmodelsiz(0.23, 0.2, 0.23)

setmodelpos(0, 0, 0)

SetModelDirection(0,1,0,degreeW)

SetModelTexture("textures/chessboard_wood.jpg")

SetModelDirection( 0, 1, 0, 90)

}

===========================================

In your opinion, what is the cause of the reflection between the plate and the pieces?

Thanks 

[عزالدين رمال‎]

Good morning Bert

After careful tracking, I found the error in the equation for distributing the pieces

setModelpos(i*17-75, 0, (7-j)*17-42)

The correct equation is

for white pieces

 setModelpos(i*17-75, 0, 37-(j*17-42))

for black pieces

setModelpos(i*17-75, 0,(j*17-42)-33)

There is another problem when selecting the pieces, he only sees 7 original pieces, the cloned copies cannot be retextured according to my understanding

[Bert Mariani]

Hello Ezzedine 

Can you tell me what these 3 variables mean for these statements.

What do the variables represent ?

Some of the constant/repetitive  values can be defined as Globals

   oboard = new Model3d(oRootEntity, oboard, "models/board.obj"){

                  setmodelsiz(0.23, 0.2, 0.23)

                  setmodelpos(0, 0, 0)

                  SetModelDirection(0,1,0,degreeW)                   // 90

                  SetModelTexture("textures/chessboard_wood.jpg")

                  SetModelDirection( 0, 1, 0, degreeW)                     // 90

            }

 oking = new Model3d(WhitePEntity, oking, "models/king.obj"){

                           setModelpos(i*17-75, 0, 37-(j*17-42))

                           setmodelSiz(0.17, 0.18, 0.17)

                           SetModelTexture("textures/WhitePiece.jpg")

                           setModelDirection( 0, 1, 0, degreeW)

                        }

[Bert Mariani]

When trying to rotate the Tiles using 45 degrees to match the Board rotation at 45 degress

See screen capture.

The individual Tiles rotate, but the placement is not correct

-------------------------------------

         aTile[i][j][:oTileTransform] = new  QTransform(aTile[i][j][:oTile]){

                                             setTranslation(new QVector3D(i*TILE_SIZE-76, 0.05, j*TILE_SIZE-76))

                                             

                                   oQ = new  QQuaternion(0,0,0,0)

                                             SetRotation(oQ.FromAxisAndAngle(new QVector3D(0, 1, 0), 45 ))  // 180

                                  

                                        }

[عزالدين رمال‎]

Hello Bert

The equation setModelpos(i*17-75, 0,(j*17-42)-33) is for distributing the boards, where each board represents a square, either white or black

It is the same for the black and white board. I made a mistake in the previous post when I said that here one is for the white board and the other is for the black.

Can you tell me what these 3 variables mean for these statements.

What do the variables represent ?

 oboard = new Model3d(oRootEntity, oboard, "models/board.obj"){

                  setmodelsiz(0.23, 0.2, 0.23)      <<<       To adjust the size of the object

                  setmodelpos(0, 0, 0)       <<<      To adjust the position of the object

                  SetModelDirection(0,1,0,degreeW) // 90     <<<        To adjust the orientation of the object

                  SetModelTexture("textures/chessboard_wood.jpg")          <<<<       To put  Texture  on the object

                

            }

It's all about  Attributes  in the  object3D class included with the files

As for the problem I raised in the previous post

It's when you select the pieces only sees 7 

There is another problem when selecting the pieces, he only sees 7 original pieces, the cloned copies cannot be retextured according to my understanding

oboard = new Model3d(oRootEntity, oboard, "models/board.obj")

When cloning from an object, this name oboard must be unique

Problem solved

As for the memory leak issue

It wasn't a leak but an overload where I was calling the update function in FrameAction()

Now I moved it to the function  HandleNewSelection( i, j)

And the app is working fine

The step of transferring the pieces from the previous board to the target board is over

Now I'm up for the rules

I changed in different files

Because Google does not accept uploading large files in posts, please download the project from the following link

Chess3d Qt3D -- drive google

[Bert Mariani]

Hello Ezzeddine,

Much improved !!!

- I see every Piece has  its own Object.

- Moves can be made 

- The Knight now face each other and in their own forward direction

- The Texture for the Knights covers only the bottom half of the piece. Will need to cover the entire Knight

Hello,

nice improvement. Still, memory leaks. For example, move two white figures (each move leaks few megs), then move black figure (leaks approx 50 megs, several times more than white figure).

[عزالدين رمال‎]

Hello iller

Can you tell me how to measure memory leaks on Windows

[Ilir]

Hello,

you can do it visually by looking at task manager, ring.exe (like I did), or you can use tools like Dr. Memory or Valgrind which I haven't used (Dr. Memory having some issue, Valgrind haven't tried).

[عزالدين رمال‎]

hello Bert

Can you help me rewrite the rules

[Bert Mariani]

Hello Ezzeddine

You are welcome to use the  "moves and rules" from my program: 

Ring->Applications->Chess->AA-ChessBoard.ring

[عزالدين رمال‎]

Hello Bert

In fact, I built these rules in short from your game, big thank you, but it still has a slight bug, which I will address later

I am not building a game of chess, it was built by hundreds of programmers, including you, I study a library ِQt3d

I still don't know how to get rid of the reserved memory while playing and even when I close the game the memory remains reserved unless I remove it manually

How do I delete the memory stored by a program before closing it?

[Bert Mariani]

Hello Ezzeddine

You might try calling the Garbage Collector , in between the moves. 

Mahmoud should be able to confirm if this will fix the memory leak, and releasing memory before closing

      CallGC()                  // FIX SPEED SLOWING DOWN  

[Mahmoud Fayed]

Hello Bert

>> "Mahmoud should be able to confirm if this will fix the memory leak, and releasing memory before closing"

(1) When we close a Windows applications, The Operating System will free all of the memory allocated by this application

If you still see the memory allocated (Through the Task Manager) --> This means the application is not closed yet

if we have something like : oApp = new QApp

Then using oApp.Quit() will close the application

(2) With respect to Memory Management in Ring, We have two types of memory allocations

* Memory Allocated by Ring VM for Ring Normal Code (Strings, Numbers, Lists, Objects)

In this case, the memory will be deleted after the end of the function scope (if it's allocated in the local scope)

Or it will stay forever while the application is running until we delete it using assignment (if it's allocated in the global scope)

* Memory Allocated by Ring Extensions (Libraries like RingAllegro, RingRayLib, RingQt, etc.)

In this case, we have Three different situations

Number(1) : For some objects, the memory is managed by the library itself (automatically) - For example in RingQt - when we create a window widget (QWidget) then we create a QPushButton as a child of this widget, Qt will manage the memory of the QPushButton, and will delete it automatically when we close the window.

Number(2) : For some objects, we have functions that create the object, and other functions that delete this object, In this case we control when to delete the memory by calling the appropriate functions, for example in RingAllegro we have

al_load_bitmap(cFileName) ---> object (C Pointer)

al_destroy_bitmap(Object)

Number(3) : For some objects, the Ring Extension manage the memory automatically and delete the memory when the object is no longer used/available/accessible through Ring code

For example the next classes in RingQt are managed classes (Ring will delete the memory automatically when the objects go out of scope)

QFont

QIcon

QDir

QSize

QString2

QStringList

QKeysequence

Nice partitioning of the code into separate modules. Makes it easier to follow !

Observation:

These message show up the the start of the program --- Texture will be invalid for this frame

Then the second set of message are forever repeated --- Unable to find suitable Texture Unit

I think this has to be fixed.

It is probably interfering with the performance of the program.

It is also easier to play and view from the perspective of your 2nd screen shot that is tilted at 30 degrees.
Rather than the view sitting right behind the pieces.

[عزالدين رمال‎]

Hi Bert

Nice partitioning of the code into separate modules. Makes it easier to follow !

Thanks. You can contribute if you want to suggest something

Observation:

I think this has to be fixed.

It is probably interfering with the performance of the program.

It is a logical error in the process of hiding the bulletin board

      At the beginning of the game

I called the pad without Texture , and as soon as the mouse focus moved to the screen, the pad appeared and the game started, but the ad was still under the pad and in memory

To fix the error I will raise the level of the bulletin board and when the focus shifts to the screen I will destroy it

I only need it once at first

It is also easier to play and view from the perspective of your 2nd screen shot that is tilted at 30 degrees.
Rather than the view sitting right behind the pieces.

To control the position of the camera in relation to the panel, press the right mouse button in the center of the panel to change the mode

Then you choose the movement. With the keyboard arrows, you can rotate the camera left and right, and let the player freely choose the viewing angle

[Mahmoud Fayed]

Hello Ezzeddine

Some comments

(1) Remove the image/photo of the chess players in the start of the game (Usage of Magnus Carlsen photo  and other chess players needs a permission - They sell these things, so don't use it)

(2) The Rules of the game needs revision, when I play at some point it says (Check) and prevent me from playing, while no Check exist, this happens when when you start playing, move pieces, eat some of them, etc.

(3) It will be nice to set Bert suggestion as the default "easier to play and view from the perspective of your 2nd screen shot that is tilted at 30 degrees"

[Bert Mariani]

Hello Ezzedine

2 Observations

First: The rotating World picture --- The continents are reversed

Second:

By 30 Degrees,  I mean ---- White pieces on the Left. The Board slight tilt up on the Left

[عزالدين رمال‎]

Hello Bert

First: The rotating World picture --- The continents are reversed

This is because the texture loader displays the images in reverse

It must be given to him in reverse to display it correctly

Example:

I plan to cancel the planets and stars to reduce memory consumption, the view of space_skybox is enough

Second:

By 30 Degrees,  I mean ---- White pieces on the Left. The Board slight tilt up on the Left

The side view was from my suggestion and you told me in this post

Note:

White pieces go on the bottom of the board

Black pieces go on the top of the board.

So I changed it to what you suggested

Now I will take it back to the side By 30 Degrees

I will change the position of the text3d so that it is always opposite the camera

I have put three colors for the sky box, blue, red and light blue, which one best suits the background ?

[عزالدين رمال‎]

Hi Bert

Does this look good

[Bert Mariani]

Sorry Ezzeddine,

I messed up the Left and Right  words

Hello Mahmoud

I'm checking in the update function that the selected board is

  Among the possible movements with a function validMove(.....)

If the condition is met

It will change the texture of the board to a green image that you have modified in Photoshop

 if selectionI > 0 and selectionJ > 0

          if validMove(board, selectionI, selectionJ, i, j, turn)

                      aTile[i][j][:oLoader].setSource(new QUrl("file:///"+currentdir()+"/textures/valid.png") )

        ok

ok

Hello Mahmoud

I don't seem to understand your question, sorry

  When I downloaded the game through the package manager it did not load the image --valid.png

  This image is placed in the textures file, which is why it does not appear in the game

Hello Mahmoud

What is the alternative available in the ring for a topic?

Qt Signals and Slots Work.

How Qt Signals and Slots Work

[Mahmoud Fayed]

Hello Ezzedine

We provide methods in each class to set the event function (As a simple replacement for Signals/slots)

Like setClickEvent() method in QPushButton

Please update the package file (package.ring)

(1) Change valid.jpg to valid.png in this line : https://github.com/azzeddine2017/Chess3d-Qt3D/blob/main/package.ring#L77

(2) When you update the code - Update the package version : https://github.com/azzeddine2017/Chess3d-Qt3D/blob/main/package.ring#L12

For example change (1.0.0) to (1.0.1)

So we can update the package using : ringpm update Chess3d-Qt3D

instead of using : ringpm remove Chess3d-Qt3D

then ringpm install Chess3d-Qt3D

Greetings,

 do you have to change the version even if the change is simple

[Mahmoud Fayed]

Hello Ezzedine

>> "Do you have to change this line as well?"

Yes, it must be changed too

Hello Mahmoud

The error in the rules of the game has been fixed

A distinction has been added in the possible movements between enemy and friend

Next development I want to add a window to start and play the game online via tcp - socket

The cause of memory consumption was also discovered

It was caused by the use of a very large image of the black pieces

[عزالدين رمال‎]

[Mahmoud Fayed]

Hello Azzeddine

>> "The error in the rules of the game has been fixed"

Thanks for the update, I will do more testing

In the next screen shot, I can't move the White Knight that exist on the right

When I select it (I can select it) - No possible moves exist!

So please revise the Knight rules

Also the game doesn't support the Castle

For now, if you added the (Castle) this will be very nice (and important for a real game play)

The point is to support moving the King two steps to the left and the rock to be on the right of the king

Or to move the king three steps to the right, and the rock to be on the left of the king

Hello Mahmoud

In the following screenshot, I can't move the white knight on the right

When I select it (I can select it) - no motions are possible!

So please check Knight . rules

Because one of the conditions for possible movements is that the piece does not leave its place so that its king will be killed

If the knight in the previous picture was in a place that could influence the black Bishop, the only possible move would have been to kill the black Bishop

In my opinion, the rules are good

Also the game doesn't support the Castle

For now, if you added the (Castle) this will be very nice (and important for a real game play)

 I will work on it 

I need some help on how to send an QByteArray via QTcpSocket

[Bert Mariani]

Hello Ezzeddine

The Pawn also has a special  En-Passant  rule that captures a passing pawn that make a 2 square move.

https://www.chess.com/terms/en-passant

[عزالدين رمال‎]

Hello Bert

Thank you for the information, I will work on it

[عزالدين رمال‎]

Hello Mahmoud

The castle has added to this commit add Castle King

And they started working on En-Passant rule

[Mahmoud Fayed]

Hello Azzeddine

>> "The castle has added to this commit add Castle King"

Thanks for the update, Very nice :D

>> "started working on En-Passant rule"

Very nice, after finishing the En-Passan rule, it will be nice to add the Pawn promotion to Queen|Rock|Knight|Bishop (When it reach the last row)

For example, In the next screen shot we have a White Pawn that reach the end of his way and deserve a nice promotion

https://www.chess.com/terms/pawn-promotion

Greetings,

[عزالدين رمال‎]

Hello Mahmoud and Bert and all

  I have added capture En-Passan in this commit add En-Passant

[عزالدين رمال‎]

Hello Mahmoud and all

The pawn  promotion  has been added when it reaches the end of the path

[عزالدين رمال‎]

hello

Changes have been made to the following commitments

The pawn promotion Qt3d_Chess.ring

The pawn promotion Redraw Delete piece

The pawn promotion update

The pawn promotion Display

The pawn promotion Global

Update Globale.ring

Some photos have also been deleted and some photos have been added

[Bert Mariani]

Hello Ezzeddine

Tested:

 Castle - King Rook  side  = ok

 En-Passant capture = ok

 Pawn promotion to Queen  =  ok

Well Done !!!

After a while I get tired of seeing the rotating board after each move.

Is is possible to have the option to let the board stay in a fixed position ?

[عزالدين رمال‎]

Hello Bert

Thanks for your support and testing

After a while I get tired of seeing the rotating board after each move.

Is is possible to have the option to let the board stay in a fixed position ?

As for the rotation process, what do you think if we make it in the keyboard arrows

[Bert Mariani]

Hello Ezzeddine

Yes, you could have the User use the Arrow Keys if he wants to rotate the board, 

or just leave the board in place.

I play faster than the time it takes the board to rotate, so I would leave the board in place.

I would rotate it when I prefer to play as the Black Player

[Mahmoud Fayed]

Hello Ezzedine

Very nice updates :D

It will be nice to add a Menu with some options like

(1) (Enable/Disable Rotation) as suggested by Bert

(2) Restart the Game to put each piece in it's original position

Keep up the GREAT WORK :D

Hello Mahmoud and everyone

I made some changes to the game

The first image of the window has options:

Hello Mahmoud

  I had asked you how to send a list or attribute of an object I just developed a little function  List2Code

We can now put the attributes of an object in a list

Convert it to string and then send it when it is received Execute it in memory using the eval function

//--------------------------

func ListToCode(aList)

cCode ="["

lStart = True

for item in aList

if !lStart cCode += "," +Windowsnl() else lStart = False ok

if isString(item) cCode += char(39)+ item +char(39)

but isnumber(item) cCode += ""+item

but islist(item) cCode += ListToCode(item)

but isobject(item)

aAttribut = attributes(item)

cCode += '['

lStart = True

for attribut in aAttribut

if !lStart cCode += "," else lStart = False ok

value = getattribute(item,attribut)

cCode +=':'+ attribut + '='

if isString(value)

cCode += '"' + value + '"'

but isNumber(value)

cCode += value

but isList(value)

cCode += ListToCode(value)

but isobject(value)

cCode += ListToCode(value)

ok

next

cCode += " ]"

ok

next

cCode += "]"+Windowsnl()

return cCode

//-------------------------

func writeMessage(cStr)

Message ="aCommand="

Message += cStr

if networkMode

oClient.sendMessage(Message)

else

oServer.sendMessage(Message)

ok

[Mahmoud Fayed]

Hello Azzeddine

>> "I just developed a little function  List2Code"

Thanks for sharing :D

Note: We added Chess3D-Qt3D to Ring Website (News Section), Also an information about the package are added to documentation (What is new in Ring 1.15?)

Keep up the GREAT WORK :D

Hello Mahmoud 

Note: We added Chess3D-Qt3D to Ring Website (News Section), Also an information about the package are added to documentation (What is new in Ring 1.15?)

Thank you very much for the good presentation

I feel like I'm part of your team, I hope I can improve my ranking in the future

By the way, I encountered a random selection between strings values and I did not find any function for this in the documentation

I hope someone can benefit from this function

alist = "a" : "z"

alist2 = 0 : 1

alist3 = [4 ,8 , "a" , "z" ,"A" , "Z",10 , 100]

? RandomList(alist)

? RandomList(alist2)

? RandomList(alist3)

//------------------------------------

func RandomList(aInput)

alist = aInput

aOutput = null

while len(alist) > 1

nIndex = random(len(alist)-1)

nIndex++

aOutput = alist[nIndex]

del(alist,nIndex)

end

return aOutput

[Mahmoud Fayed]

Hello Azzeddine

The RandomList() function is used in the next applications

(1) https://github.com/ring-lang/ring/blob/9ec40faf388bdf300c49b438b259d7b6389e0ee0/applications/moneyboxes/moneyController.ring#L76

(2) https://github.com/ring-lang/ring/blob/9ec40faf388bdf300c49b438b259d7b6389e0ee0/applications/questions/QuestionsGame.ring#L157

(3) https://github.com/ring-lang/ring/blob/9ec40faf388bdf300c49b438b259d7b6389e0ee0/applications/lottery/lottery.ring#L284

And more!

This is  a mistake!  - It will be added to StdLib (functions) in Ring 1.15 - And all of these applications will be updated to use it and avoid code duplication

Greetings,

Mahmoud

[عزالدين رمال‎]

Hello Mahmoud

If you check the observation of the described functions, you will find that their output is a list, meaning that it randomly mixes the order

I am talking about choosing from the list one element at random and the output of the function is from the origin of the type of the list elements, either numbers or strings...

Greetings,

Azzeddine

[Mahmoud Fayed]

Hello Ezzeddine

>> "I am talking about choosing from the list one element at random"

Very nice, Could you rename it to RandomItem() instead of RandomList()

Also using a simple implementation

aList = 1:5
? RandomItem(aList)
func RandomItem aList
    if ! isList(aList) raise("Error: The function expect a list!") return ok
    if len(aList) <= 0  raise("Error: No items in the list") return ok
    return aList[ random( len(aList) - 1 ) + 1 ]

Mahmoud

Hello bert

II fixed the first mistake in these lines

As for the camera rotation, it's so slow that you won't even feel the movement

I think it is a compromise

I have a problem that I could not solve, which is when playing a set of moves, the game stops without any error and I cannot determine the reason

I tried to use an algorithm MinMax in the game, but it gives wrong results, so I just wrote a simple function based on filtering movements

As for playing online, I could not test it on my weak device, it could not open the game twice at the same time

I hope you will read the code and help me with the correction

[عزالدين رمال‎]

Hello bert

[عزالدين رمال‎]

Hi Bert

I started experimenting with online gaming

[Mahmoud Fayed]

Hello Azzedine

>> " I fixed the error"

Very nice, this what happens during programming sessions and problem solving, Continue :D

>> "I started experimenting with online gaming"

This will be GREAT :D

For now, I copied your previous work to this package : https://github.com/ringpackages/Chess3D-Qt3D

As a stable version that we talked about in (Ring 1.15 documentation)

So this command :  ringpm install Chess3D-Qt3D

Will install the old version

While this command : ringpm install Chess3D-Qt3D from azzeddine2017

will install the new version (under development)

Keep up the GREAT WORK :D
