ShaderAsset.PropertyID

Method - Static

public static int PropertyID(string name)

Parameters

name

string

Name of the property

Returns

int

Unique ID

Description

Get a unique ID of a shader property. Property IDs are more efficient than property name strings, and should be used instead for optimal performance.

Note that property IDs are tied to the property name, not to any particular shader. The same property ID can be used with multiple shaders that have the same property names.

Example

SpriteSheetAsset spritePackCharacters = new SpriteSheetAsset();
ShaderAsset shaderEffects = new ShaderAsset();

const int SHADER_PROP_GLOW = RB.ShaderPropertyID("glow");

void Initialize() {
    spritePackCharacters.Load("spritesheet/tiles");
    shaderEffects.Load("shaders/effects");
}

void Render() {
    RB.SpriteSheetSet(spritePackCharacters);

    // Draw a sprite with a shader effect
    RB.ShaderSet(shaderEffects);
    shaderEffects.ColorSet(SHADER_PROP_GLOW, Color.yellow);
    RB.DrawSprite("glowing_hero", glowingHeroPos);

    // Turn off shader and draw a sprite with default RetroBlit shader
    RB.ShaderReset();
    RB.DrawSprite("boring_hero", boringHeroPos);
}
