I'm currently working on a simple 3D VR game with Godot. What I couldn't figure out yet is how to create color overlays for the whole screen.
To make clearer what I want two achieve, here are my two main use cases:
1) When the player takes damage, the screen should get tinted red for a few milliseconds.
(this helps the player to realize he has been hit, especially if the enemy is behind him/her)
2) When changing the scenes, I want to fade the old scene to black, then fade in the new scene after it has been loaded.
(especially in VR this makes scene transitions much more pleasant)
For both use cases I would need to draw a color (with variable alpha) over the actual scene. Can anyone give me a hint on how this can be achieved with Godot?
