onLivingUpdate does not appear to be triggering

[Acrogenous]

I have created an entity, an explosive to be precise, but the function onLivingUpdate does not appear to be firing at all. I have a println on the initiating of the class saying it has worked and then 2 more print lines in the onLivingUpdate section, these dont seem to be firing however, what am I doing wrong?

public class EntityExplosive extends EntityPig {
    int fuse;
    EntityPlayer player;
    BlockPos coords;
    float explosion;
    World world;



    public EntityExplosive(World getworld, BlockPos getcoords, EntityPlayer getplayer, float getexplosion, int getfuse)
    {

        super(getworld);
        System.out.println("it worked");
        this.fuse = getfuse;
        this.player = getplayer;
        this.coords = getcoords;
        this.explosion = getexplosion;
        this.world = getworld;
    }
    @Override
    public void onLivingUpdate() {
        System.out.println(this.fuse);
        if(this.fuse != 0)
        {
            this.fuse --;
            System.out.println("counting down");
        }
        if(this.fuse < 1)
        {
            this.world.createExplosion(this.player,this.coords.getX(),this.coords.getY(),this.coords.getZ(),this.explosion,true);
            this.setDead();
            return;

        }
        super.onLivingUpdate();
    }


}

It extends EntityPig so I didn't have to construct the rest of the class.  the variables passed on creation of the EntityExplosive are: the world, the blockpos, the player, 10 and 100.

thank you in advance.

Ah! that makes sense. I did do that before (I was following some code form DefenseTech) but didn't think it was necessary, thank you very much!

[Acrogenous]

if I want the entity to have those variables passed on to it when it is created, how would I go about doing that?

 

I seem to be getting a problem with a ticking entity.  saying there is a nullPointer on the "createExplosion" line. why is this?

 

the problem in fact seems to lie in the entity not existing past 1 tick...

I have since deleted the class as I found an alternative way to get to a solution. I may re-implement this entity at a later date and if I get the same problem I shall post the code and stacktrace here
