Entity's Navigation

Hello!

I am currently trying to get a pig to follow a player around. I am trying to use

Code:java

    public boolean walkTo(Entity p, Location l){
        return ((EntityAnimal)p).getNavigation().a(l.getX(), l.getY(), l.getZ(), .25);
    }

I keep getting ClassCastException whether I sue EntityAnimal, or EntityCreature. I normally would cast it to EntityLiving it doesn't seem to have a navigation feature.

Any idea how I can modify it so that it does work?

 

Have you checked if entity is instanceof EntityaAnimal? Also I think there is settarget method that makes a entity follow another entity though I'm not sure it exists for entity pig but ok, here is a tutorial with nms and how to make an entity walk twards something http://forums.bukkit.org/threads/tut-making-a-livingentity-walk-to-a-specific-tile.139086/

Hopefully that helps =]

Cast to EntityInsentient. Something like this

Code:java

public boolean walkTo(Entity p, Location l) {
    return (((EntityInsentient) (LivingEntity) p)).getNavigation().a(l.getX(), l.getY(), l.getZ(), .25);
}

I check to see if the Entity's Type is a pig, which would fall under the category of animal. I am trying not to use pathfinders as I don't want to re-create the mob.

Just tried using EntityInsentient, still not working. Still get the error CraftPig cannot be cast to EntityInsentient.

 

97WaterPolo oh I'm sorry :-(

 

I may be wrong, but wouldn't you want to cast p.getHandle() to EntityAnimal instead of p?

 

97WaterPolo
Whoops.

Code:java

return (((EntityInsentient) (LivingEntity) p).getHandle()).getNavigation().a(l.getX(), l.getY(), l.getZ(), .25);

Don't know if brackets are correct there, wrote it on my phone.

edit: Ninja'd.

Am I missing something, but neither EntityAnimal, nor EntityInsentiet have a getHandle() method?

 

97WaterPolo
That's because I messed up the brackets () there. You can probably just get rid of EntityInsentient and cast to (Craft)LivingEntity only.

Thanks! Figured it out, there is a getNavigation() method for CraftPig, so I checked to see if it was a Pig, and if so casted to CraftPig. Thanks for all the help, still kinda clueless as to why EntityInsentiet didn't work.
