Position GUI control at PointerDown


Recommended Posts

So this kinda works..


Breaks as soon as you play with canvas or browser dimensions. 

Next tried to do some calculations following this StackOverflow post


The PG is broken, canvas.getContext('2d') returns null.

I suspect I will need to get the AdvancedTexture context, but not sure how. Than use it's currentTransform property to calculate the position. Open to ideas.

Hey ! I am no pro but I would suggest not to interact with canvas directly as it might result in context loss. Use the core engine's/ADT (https://doc.babylonjs.com/api/classes/babylon.gui.advanceddynamictexture) built in functions.

You can use this PG for reference-  https://www.babylonjs-playground.com/#XCPP9Y#658,  look how scene.onPointerMove updates the rectangle's position :)
