How can my entity search for a certain type of block (an easy way)

[kauan99]

Hi everyone! I'm studying EntityAnimal now. I'd like to know if it's possible to make it look for a certain type of block.

 

I can make it find another Entity or subclass of entity using an algotithm kind of inspired by the one in EntityAINearestAttackableTarget.shouldExecute(), but I don't know how to use Bounding Boxes to detect the presence of blocks (yeah, still shooting in the dark when it comes to bounding boxes. Why doesn't anyone answer my questions about that? :'(). I use the same World.selectEntitiesWithinAABB used by shouldExecute method mentioned earlier.

 

Is there way to make an EntityAnimal find a block? (one that doesn't involve nested for loops to look at every block in an area around the animal, cause I think that would have a sensible performance impact)

 

Thanks in advance!!

 

P.S.: I didn't post my code for finding entities because it's not relevant, would be distracting and it doesn't do what I want, that is, to find a specific block. But if anyone is interested I can post it, as an off-topic answer.

You could do a three dimensional loop worth of getBlockID(x,y,z).

You could do a three dimensional loop worth of getBlockID(x,y,z).

 

That was my initial ideia but I think that can be a performance breaker. The number of objects of MyEntityAnimal can be any arbitrarily big number (as many as the player spawns through eggs or breeding) and I think things would break pretty soon. Unless there's a way to make nearby MyEntityAnimal mobs act as one (they do just one search and share the location of the special blocks found among each other).

 

Do you think that's possible?

No idea. :\
