How To Modify RGBA Colors Of A 2D Sprite? - Godot 4

JeZxLee

Hi,

Trying to figure out how to modify the RGBA colors of a sprite in Godot 4.

Godot 3.5 did it like below:
Sprites.SpriteImage[60].modulate = Color(1.0, 1.0, 1.0, 0.4)

Any help would be appreciated , thanks!

Have below code now, but with below error:

RenderingServer.canvas_item_set_modulate(Sprites.ci_rid[60], CanvasModulate().set_color(1.0, 1.0, 1.0, 0.4))
# Function "CanvasModulate()" not found in base self.

Below shows no error:

RenderingServer.canvas_item_set_modulate(Sprites.ci_rid[60], Color(1.0, 1.0, 1.0, 0.4))

But I don't know if it works yet - framework is in a state of disarray at this moment...

Sprite in Godot 3.x and Sprite2D in Godot 4 have a set_modulate function.

set_modulate(Color(1.0, 1.0, 1.0, 0.4))

Just wondering, is there any reason you don't use the scene graph?

Building a custom engine on top of godot, they likely have their own custom MainLoop.

Yes... we are building a "framework" 100% entirely in Godot 4 GDScript:
