Hello folks, i need disable tree growth for some saplings. I tried to do it using SaplingGrowTreeEvent but encountered with 2 problems. First: it's doesn't called and i can't catch it with event handler (When i grow tree my event method doesn't called), second: i can't get type of tree from this event. All code below.

[spoiler=My event]

	@SubscribeEvent
public void onTreeGrow(SaplingGrowTreeEvent e)
{
	Core.instance.logger.log(Level.INFO, "Sapling event fired");
	if(e.world.getBiomeGenForCoords(e.x, e.z) == BiomeGenBase.taiga)//Here i need to add conditional if type of tree not equals spruce
	{
		e.setResult(Result.DENY);
	}
}

 

[spoiler=Event handler registration]

	public EventHandler events = new EventHandler();
	MinecraftForge.EVENT_BUS.register(this.events);
	FMLCommonHandler.instance().bus().register(this.events); 

 

Read the Javadoc of the event, it clearly states that:

This event is fired on the MinecraftForge#TERRAIN_GEN_BUS

 

so register it there.

 

To get the sapling type? Just get the block instance from the coords and if it's a sapling, check through its metadata which type it is.

Wow, didn't know that there different kinds of buses, thanks!

Do not worry; it will always tell you which bus to use, in the Javadoc.
