Stop UV from rotating with Sprite2D

Question

I am trying to make a wave shader on the player sprite, where If (UV.x < 0.5), then it switches between two colors. I want the UV to not rotate when the player rotates. Is there anyway to do this?

Do you have some shader code you are already trying that I can see?

I hope I am understanding your ask and I am not the best with shaders but here it goes. I THINK the screen space won’t be affected by the Player’s movement/rotation and I THINK you can do something like this to get what you need in the shader:

// Transform the UVs to avoid rotation with the player sprite
    vec2 screen_uv = (FRAGCOORD.xy / SCREEN_PIXEL_SIZE) / SCREEN_SIZE;

    // Apply conditional logic based on the x-coordinate of the screen space UV
    if (screen_uv.x < 0.5) {
        // Switch between two colors, for example red and blue
        COLOR = vec4(1.0, 0.0, 0.0, 1.0);  // Red color
    } else {
        COLOR = vec4(0.0, 0.0, 1.0, 1.0);  // Blue color
    }

I have not tested this and some of my Godot shader code may be a little outdated since I haven’t dealt with Shaders in a good while and I really don’t like messing with them LOL but hope this may help get you in the right direction.
