Can I have the game detect if a player just spawned?

[MINERGUY67880]

Hi, I need my mod to detect if a player just spawned into the world for the very first time so that I could do something like:

if (playerJustSpawned = true) {
System.out.println("Hey, A player just spawned!")
}

Is there one that is in the source code or do I have to make one? Please help me out with dis!

There is a forge event that get always called when a entity kind gets spawned (any entity) just add a entity player filter and then you can work with it

What is it called and what class is it from?

Have you used Forge Events before? If not, this may be helpful.

 

Look in net.minecraftforge.event and you will see all the different kinds of events available. The one you are looking for is called EntityJoinWorldEvent. You could also implement an IPlayerTracker, which has methods to handle login and spawn.

Will this be sufficient?

@EventHandler
       public void load(EntityJoinWorldEvent EntityPlayer){
	   System.out.println("A PLAYER JUST JOINED!");
   }

How can I change that to make it work?

[coolAlias]

The reason he is suggesting using IPlayerTracker is because it is only called for players, whereas EntityJoinWorldEvent gets called for EVERY single entity, including thrown items, mobs, etc., so you are doing a lot of wasteful processing if you only care about instances of EntityPlayer.

Will this be sufficient?

@EventHandler
       public void load(EntityJoinWorldEvent EntityPlayer){ //type here is type Event, variable name is EntityPlayer.  This will confuse you
	   System.out.println("A PLAYER JUST JOINED!");
   }
