[spoiler=FirstEventHandler.java]

package com.phoenix.firstmod;

import net.minecraft.client.Minecraft;
import net.minecraftforge.event.world.BlockEvent.PlaceEvent;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;

public class FirstEventHandler {
@SubscribeEvent
public void onBlockPlace(PlaceEvent event){
	Minecraft.getMinecraft().thePlayer.sendChatMessage("Block Placed");
}
}

 

 

Above is the code from my handler class, I use "FirstEventHandler handler = new FirstEventHandler();" and " MinecraftForge.EVENT_BUS.register(handler);

FMLCommonHandler.instance().bus();" in my main class.

 

My issue is that in game when I place a block, the event fires twice and sends two chat messages. Chat messages are not my final intended function, but just to

make sure I'm not messing this up, which I evidently am.

So I'm struggling to understand events, would I use @SideOnly somehow? How would I make this only happen once?

I've been messing with this for a while and can't figure it out, I want to store placedBlock from PlaceEvent in a variable (thats what I need help with) and then output to chat.
