I am trying to work out some AIs but I am having toruble, it doesn't execute anything. This is my code, I have put system output markers all over to see where it goes and all I get is "supered" which is the initialization part, all the others do not occure so it doesn't even TRY to execute anything, why?

Mob:

	public MobThief(World world) {
	super(world);
        System.out.println("Thief is mobbing");
        this.targetTasks.addTask(1, new EntityAIRunIfSeenByTarget(this, EntityPlayer.class, false, false));
}

AI:

}

first what are you extending for MobThief

second try putting the priority up :  this.targetTasks.addTask(50, n........

also put this in your ai

@Override
public boolean isInterruptible() {
	//System.out.println("isInterruptible");
	return false;
}

 

so.....priorty isn't first second third order but rather higher number = greater priority....dagnamnit

 

I am extending entitymob

 

What I am trying to create is a mob that spawns randomly throughout the day, runs up to a player if they are not seen and then away if they are seen, once they hit the player they grab one of the players tiems and runs off with it

I may add that when I tyr putting some code in the MobThief class which si the entitymob extended one

        	Vec3 targetVec = Vec3.createVectorHelper(this.posX - this.lastTarget.posX, this.boundingBox.minY + (double)(this.height / 2.0F) - (this.lastTarget.posY + (double)this.lastTarget.getEyeHeight()), this.posZ - this.lastTarget.posZ);
        	double xPosition = this.posX+20*Math.signum(targetVec.xCoord);
        	double yPosition = this.posY+20*Math.signum(targetVec.yCoord);
        	double zPosition = this.posZ+20*Math.signum(targetVec.zCoord);
            System.out.println("New X: " + xPosition);
            System.out.println("New Y: " + yPosition);
            System.out.println("New Z: " + zPosition);
            System.out.println("Move: " +  this.getNavigator().tryMoveToXYZ(xPosition, yPosition, zPosition, 5));
            this.getNavigator().tryMoveToXYZ(xPosition, yPosition, zPosition, 50);

this code, it seems to get the target but the mob never runs toward it, how come?
