Setting sprite transparency via CanvasItem

I’m trying to hide a sprite by changing its transparency. I see that a Sprite’s CanvasItem component has a Color() function, and that the last value controls alpha, so I’m trying to do something like:

	var canItem = GetNode("CanvasItem")


This doesn’t work. How do I access the CanvasItem?

You can see the available properties and methods of CanvasItem here:

As you can see “Color” is not a property.

If you want to use transparency as in your example, you need to set the modulate property:

canItem.modulate = Color(1, 1, 1, 0.5).

If you’re just interested in transparency you can do canItem.modulate.a = 0.5.

There’s also a self_modulate counterpart if you don’t want the same effect applied to all of that Node’s children.
