How to load and use the effect files?

FX fx = FXHelper.getFX(ResourceLocation.parse("photon:fire"));
// bind it to a block
new BlockEffectExecutor(fx, level, pos).start();
// bind it to an entity
new EntityEffectExecutor(fx, level, entity, AutoRotate.NONE).start();

Implement your ownIEffectExecutor to manage the lifecycle of your photon effects.

Sometimes, you wanna control the effect you have with additional logic. You can implement the IEffectExecutor and do what you want.

IEffectExecutorExampleExecutor

public interface IEffectExecutor {

    Level getLevel();

    /**
     * update each FX objects during their duration, per tick. Execute low frequency logic here.
     * <br>
     * e.g., kill particle
     * @param fxObject fx object
     */
    default void updateFXObjectTick(IFXObject fxObject) {
    }

    /**
     * update each FX objects during rendering, per frame. Execute high frequency logic here.
     * <br>
     * e.g., update emitter position, rotation, scale
     * @param fxObject fx object
     * @param partialTicks partialTicks
     */
    default void updateFXObjectFrame(IFXObject fxObject, float partialTicks) {

    }

    default RandomSource getRandomSource() {
        return getLevel().random;
    }
}

public class ExampleExecutor extends IEffectExecutor {
    public final FX fx;
    @Getter
    public final Level level;
    // runtime
    @Nullable
    private FXRuntime fxRuntime;

    public ExampleExecutor(FX fx, Level level) {
        this.fx = fx;
        this.level = level;
    }

    public void emit() {
        kill();
        fxRuntime = fx.createRuntime(); // (1)
        fxRuntime.emmit(this);
    }

    public void kill() {
        if (fxRuntime == null) return;
        fxRuntime.destory(true);
        fxRuntime = null;
    }
}

1. if you want to modify config data. use fx.createRuntime(true) instead.

Check ExampleExecutor to see how it works.

FX fx = FXHelper.getFX(ResourceLocation.parse("photon:fire"));
var executor = new ExampleExecutor(fx, level);
executor.emit();
