MoonPhase help

[GatoLeyo]

Im new at modding so probably this have an obvious error but plz somebody tell me how can i make this works, it is intended to return a value in relation to the moon phase

 

    public float endWorldTick(TickEvent.WorldTickEvent event) 
    {
        float x = 0;
        if(event.side.isServer() && event.phase == TickEvent.Phase.END) 
        {
            World world = event.world;
            if(world.provider.getDimension() == 0) {
                if(world.getMoonPhase() == 1.0f) 
                {
                  x = 15.0f;
                }
            }
        }
        return x;
    }

Events don't return values.

Second, I'm pretty sure getMoonPhase() is client side only.
