Custom Colored Flash

This little shader is my go-to for making quick hit or flash effects in Godot. Whenever something gets damaged or you want to grab the player’s attention, this shader makes the sprite flash a bright color — super simple but really effective!

Parameter	Description
flash_color	The color used to “flash” the sprite.
flash_modifier	Controls the intensity of the flash (0 = no flash, 1 = full flash).

shader_type canvas_item;

uniform vec4 flash_color: source_color = vec4(1.0);
uniform float flash_modifier: hint_range(0.0,1.0) = 1;

void fragment() {
    vec4 color = texture(TEXTURE, UV);
    color.rgb = mix(color.rgb, flash_color.rgb, flash_modifier);
    COLOR = color;
}
