Problem with addChatMessage sending twice


Recommended Posts

Hey all I've got a little problem with addChatMessage, when activated it sends the chat message twice.

public void onBlockClicked(World world, int i, int j, int k, EntityPlayer entity)
	entity.addPotionEffect((new PotionEffect(Potion.moveSpeed.getId(), 300, 0)));
	entity.addPotionEffect((new PotionEffect(Potion.digSpeed.getId(), 300, 1)));

	entity.addChatMessage((new ChatComponentText("Test")));



As you can see it's sending the message twice instead of once when the block is clicked once.


Any help would be much appreciated. :)


Thanks all!

My guess is that it's being called on the server and the client.


Potion effects should only be done server side, so you should put those inside if(!world.isRemote)


world.isRemote returns true for the client and false for the server.


As for the messages, also put them in an if. Since I think addChatMessage only works for the EntityPlayer itself, I don't think it matters whether it's done server side or client side. Just not both.



I'll help if I can. Apologies if I do something obviously stupid. :D


If you don't know basic Java yet, go and follow these tutorials.
