parameters for scene.mouse.pick()

[EDUCATIA SUPERLATIV]

Hi,

I want to know all parameters for scene.mouse.pick()?

How can I obtain the nameX of the object?

Example:

nameX = box({...})

let hit = scene.mouse.pick()

I want to obtain string = ”that NameX” after pick on object?

The ”hit.constructor.name” show the type of the object!!!!

Best regards,

Ciprian

Have a look at this modified example picking program.

https://glowscript.org/#/user/johncoady/folder/My_Programs/program/PickName

If you pick an object it will print the name of the object that I assigned it when it was created. For instance I added the name 'green box' to the box object when I created it.

box(pos=vector(1,-1,0), color=color.green, name='green box')

and I print the name in the getevent() routine

        print("Pick Name : ",lasthit.name)

Simpler example https://glowscript.org/#/user/johncoady/folder/My_Programs/program/PickName

Web VPython 3.2

cube = box()
cube.name = "cube"
t = 0
dt = 0.1
while t <= 20:
    rate(10)
    now = scene.mouse
    if not now.pick == False:
        print(now.pick.name)
    else:
        print("nada")
    t+= dt

I work with VPython in Html!

I tested like this:

”

let Hbox = box( {pos:Hpoz, size:vec(dX, dY, dZ), color:cList[colID]}, name = NameX )  //OK
print("Current Name : ", NameX)   // OK

”
But when I click on the object it say ”Pick Name :  undefined”!

Best regards,

Another observation!

Another difference was not defined variables like global in HTML!

”//global lasthit, lastpick, lastcolor”

Doesn't work!

Is it possible to define in HTML VPython global variables?
