How to call ccbRegisterOnFrameEvent(onFrameDrawing) inside onAnimate.

Got it drawn.
But suppose I am drawing a circle using ccbRegisterOnFrameEvent. Once I don't need it anymore, how do I remove that circle or how do I stop drawing it?
Calling ccbUnregisterOnFrameEvent is not removing that circle!

What platform are you using?
If unregistering doesn't work (which it should, but as workaround:), you can store a variable and set it to 'true' and 'false' if you should draw a circle. It it is set to false, just don't draw it.
That would definately work, independent of the unregister function works or not.

here is the drawing code, calling from inside onMouseEvent


var down = false;
var mX = 0.0;
var mY = 0.0;

if (mouseEvent == 2)
{
	down = false;
}

if (mouseEvent == 3)
{
	down = true;
}

// draw the rectangle
function onFrameDrawing()
{
	var mouseX = ccbGetMousePosX();
	var mouseY = ccbGetMousePosY();
				
	ccbDrawColoredRectangle(0x444BC050, mX, mY, mouseX, mouseY);
}
	
if (down == true)
{
	// register the drawing function
	ccbRegisterOnFrameEvent(onFrameDrawing);
}
else
{
	// unregister the drawing function
	ccbUnregisterOnFrameEvent(onFrameDrawing);
}

It is windows 7. Exporting as a exe.

Ah, I think the problem is that your function is inside that function. You are always unregistering a different function. Move the function and the down to outside the onMouseEvent, then is should work.

Ok, got it, down was not needed, just called it directly. Thank you.
