SaplingGrowTreeEvent not working?


Recommended Posts

Hi, I try to deny tree growing in specified dimensions. I've found SaplingGrowTreeEvent but I can't get it to work.


public void init(FMLInitializationEvent event) {
	MinecraftForge.TERRAIN_GEN_BUS.register(new TerrainEvents());
	MinecraftForge.EVENT_BUS.register(new TerrainEvents());


public class TerrainEvents {
	public static void onSapling(SaplingGrowTreeEvent event)
		System.out.println("TreeGrowEvent Triggered");
		for (String curdim : ConfigManager.DenyInDims) {
			String[] cs = curdim.split(";");
		    if (event.getWorld().provider.getDimension() == Integer.valueOf(cs[0])) {
		    	if (cs[1].toCharArray()[0] == 't') {


Forge Version: forge-1.12.2-


What is going wrong? It seems like the event never fires.
Thank you for your help.

When registering an instance of your event handler with


then you have to use non static events handlers. Or you can pass the complete event handler class.

You can also automatically register your event handler by annotating your event handler class with @Mod.EventBusSubscriber.

You can read more about it here: https://mcforge.readthedocs.io/en/latest/events/intro/

You can also register the class thusly:
