I want to increase the growth rate of crops using the CropGrowEvent.Pre event randomTick method of a BlockState in 1.16

[Andrew Murdza]

I want my mod to change how quickly crops grow based on the biome. But when I test my mod the crops grow the same regardless of the biome. I have other methods inside of ModClientEvents that do work and when I add a print statement above the state.randomTick line it gives the correct score that the biomes should have when I am within each biome which means that the method is being called when the event occurs, the method calculates the biome scores connectly, and the code inside of the if statement is being run. This makes me think that the problem is with state.randomTick. How I can fix my code to make it so that state.randomTick actually alters the growth age of crops?

@Mod.EventBusSubscriber(modid = AOEMod.MOD_ID, bus=Mod.EventBusSubscriber.Bus.FORGE, value= Dist.CLIENT)
public class ModClientEvents {
    public static double[] growth_chances=new double[]{0,0,1.0/3.0,1.0/2.0,2.0/3.0};
    @SubscribeEvent
    public static void onPlantTick(BlockEvent.CropGrowEvent.Pre event) {
        IWorld world=event.getWorld();
        BlockPos pos=event.getPos();
        BlockState state=event.getState();
        int score=getScore(world,pos,state.getBlock());
        if(world.getRandom().nextDouble()<growth_chances[score]){
            state.randomTick((ServerWorld) world,pos,world.getRandom());//NOT WORKING!!!
        }
    }
}

I'm sorry for wasting your time I figured out that the reason it wasn't working is because I used to use a different scale of biome scores (with varied between 0 and 2 instead of 0 and 4) which made the crops seem to grow at the same rate. When I scaled the scores by 2 everything worked.

Don't use state.randomTick, that fires the vanilla logic again. You want to make the crop grow if your random returns true, set the event's result to ALLOW.
