How to find move direction on image

[Omer Meshy]

Hello
How can I get the direction of the move with img.setontouchmove?

Hi Omer.

Maybe you can track the position of the touch. It should be included in the returned event. Store X and Y of the initial touchmove and check for the succeeding X and Y's of the event. Just remember that 0,0 is at the topleft corner of the image object. So when X increases therefore you probably going to the right horizontally. And when Y increases, the touch is going down vertically. And from that in mind you can even get the angle of displacement.

Omer,

The reference on the app shows that img.SetOnTouchMove passes an event

The event has

object: {source, action, count, x:[x1,x2,x3], y:[y1,y2,y3]}

the appobject, string Move, integer, six fractions 0 ... 1

not clear what x1/2/3 and y1/2/3 are

Regards, ah

I've added this popup to the next docs version - hope this makes things clear

I would use OnTouch rather than OnTouchMove

In the code below you can use xMove and yMove to calculate the direction the finger has moved

function OnStart()
{
var lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
var img = app.CreateImage( null, 0.8, 0.8 );
img.SetColor( "red" );
img.SetOnTouch( img_OnTouch );
lay.AddChild( img );
app.AddLayout( lay);
}

function img_OnTouch( ev )
{
if(ev.action=="Down")
{
this.data.lastX = ev.X;
this.data.lastY = ev.Y;
}
else if(ev.action=="Move")
{
// negative xMove is left
var xMove = ev.X - this.data.lastX;
// negative yMove is up
var yMove = ev.Y - this.data.lastY;
this.data.lastX = ev.X;
this.data.lastY = ev.Y;
}
}

[Steve Garman]

And if you just want to know about movement from down to up

function img_OnTouch( ev )
{
if(ev.action=="Down")
{

this.data.firstX = ev.X;
this.data.firstY = ev.Y;

}
else if(ev.action=="Move")
{
// negative xMove is left
var xMove = ev.X - this.data.lastX;
// negative yMove is up
var yMove = ev.Y - this.data.lastY;
}

else if(ev.action=="Up")
{
var xOverall = ev.X - this.data.firstX;
var yOverall = ev.Y - this.data.firstY;
var msg = "whole touch moved\nX: "+
xOverall+"\nY: "+yOverall
//app.ShowPopup( msg );

Thank you.

I thought about that but I didnt know if there is an easy way.

[Omer Meshy]

It works! Thanks a lot.

Here is my code:

controlImg = app.CreateImage( null, 1, 1 );

controlImg.SetPosition(0, 0);

controlImg.SetOnTouch(ControlOnTouch);

controlImg.direction = "";

lay.AddChild(controlImg);

function ControlOnTouch(ev)

{    

    if(ev.action=="Down")

    {

        this.data.lastX = ev.X;

        this.data.lastY = ev.Y;

    }

    

    else if(ev.action=="Move")

    {

        // negative xMove is left

        var xMove = ev.X - this.data.lastX;

        // negative yMove is up

        var yMove = ev.Y - this.data.lastY;

        

    //txt.SetText(xMove + "\n" +  yMove + "\n" + controlImg.direction);

   

    if(xMove < 0 && (yMove < 0.001 && yMove > -0.001))

        {

            this.direction = "Left";

        }

        

        else if(xMove > 0 && (yMove < 0.001 && yMove > -0.001))

        {

            this.direction = "Right";

        }

        

        else if(yMove < 0 && (xMove < 0.005 && xMove > -0.005))

        {

            this.direction = "Up";

        }

        

        else if(yMove > 0 && (xMove < 0.005 && xMove > -0.005))

        {

            this.direction = "Down";

        }   

   

        this.data.lastX = ev.X;

        this.data.lastY = ev.Y;

    }

}

Hello, is there anyone here who can help me? I have contacted the developer of DroidScript a few days ago but there has been no response to date even though I have subscribed to premium.

I use firebase. Can anyone give me a sample code or plugin to make "Sign in with Google" on DroidScript?

Anyone who can help me, please contact me via: riski...@gmail.com

[Symbroson]

Please start a new thead in this or the premium forum if your issue is not directly related to the topic in this thread

[Alan Hendry]

Idrus,

I presume that you want the user to type in a Google email and password.

Add Google Sign-In to Your Android App - https://developers.google.com/identity/sign-in/android/

(It looks like some-one would have to write a plugin in Android Studio to use this)

Regards

Hey again

I worked more on the code and know it works even better:

function ControlOnTouch(ev)

{    

    if(ev.action=="Down")

    {

        this.data.lastX = ev.X;

        this.data.lastY = ev.Y;

    }

    

    else if(ev.action=="Move")

    {

        // negative xMove is left

        var xMove = ev.X - this.data.lastX;

        // negative yMove is up

        var yMove = ev.Y - this.data.lastY;

   

    if(xMove < 0 && Math.abs(xMove) > Math.abs(yMove))

        {

            this.direction = "Left";

        }

        

        else if(xMove > 0 && Math.abs(xMove) > Math.abs(yMove))

        {

            this.direction = "Right";

        }

        

        else if(yMove < 0 && Math.abs(xMove) < Math.abs(yMove))

        {

            this.direction = "Up";

        }

        

        else if(yMove > 0 && Math.abs(xMove) < Math.abs(yMove))

        {

            this.direction = "Down";

        }

   

        this.data.lastX = ev.X;

        this.data.lastY = ev.Y;

    }

}
