Make something happen to the player every x ticks or every tick.

[sigurd4]

im trying to have a variable that goes down every x ticks and is stored as nbt in the player. what is the proper function for this. (i read somewhere that it was onUpdate() but it must have been outdated) and how in the world do i set up a tick handler? here is my code:

 

package com.sigurd4.Bioshock.entity;

import net.minecraft.entity.Entity;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.nbt.NBTTagList;

	this.player = player;
	this.eveMax = 200;
	this.setCurrentEve(this.eveMax);
	this.setDrunkness(0);
}

public void onUpdate() //this doesnt work!!
{
	setDrunkness(getDrunkness()-1);
	System.out.println(getDrunkness());
}

/**

 * This method is for convenience only; it will make your code look nicer
 */

{
	return (ExtendedPlayer) player.getExtendedProperties(EXT_PROP_NAME);
}

how in the world do i set up a tick handler?  ...

i dont know what to do and its hard to find any tutorials that are up to date.

 

I've just drafted a tutorial on 1.7.2 event handling.  There is a lot of information there, but it should explain the concepts, how to register handlers, and list of various available events.

 

As diesieben07 advises, there is PlayerTickHandler (on FML event bus) available.  Just create a counter there that you can test to see that so many ticks have gone by and you can use event.player to find the player and then you can call his NBT handling methods.

[sigurd4]

took a look at your tutorial, and it is pretty good, but there is one thing that i cant find there and makes me confused and that is where am i supposed to put this code? could you give me an example?

[jabelar]

Okay, I'm still planning to augment the tutorials with full github examples, although I did put a lot of instruction into the tutorial.  I'll see if I can make a clearer summary though because I guess I do have a lot of information there.

 

The basic idea is:

1) Create an event handling class, call it whatever you want.  I give an example of such a class in the tutorial.

2) Put a method in it that follows the example in my tutorial.  In needs to have the @SubscribeEvent annotation and the parameter must be the type of event you're trying to handle (I put lists of pretty much all known events in the tutorial).  That method should do whatever you want when the event happens.

3) register the handling class to the event bus.  This is done in your main class (or CommonProxy) in the init() method.  I give examples of registering the class to the bus in my tutorial.

 

That's pretty much it.
