Moving an entity to a certain coordinate and then checking if it has done so

[SamTebbs33]

Hi! I'm making a mob which moves to a certain location, breaks a block and returns to it's original location. This is repeated for every block of that type in the area.

 

I've already got a for loop to account for each block, but how would I go about moving the entity to the location of the block and then checking if it has done so? I have tried using a while loop and checking if the entity's position is close to the block's, but that crashed the game...

 

Here's the method I'm using to move the entity:

public void moveEntityTo(int x, int y, int z){

this.getNavigator().tryMoveToXYZ(x, y, z, 0.3D);

    }

Thanks!

Hi

 

The basic problem is that it takes time for the Mob to get where it's going and you have to let the game run while you wait for it to get there.  For some background info see here:

I would suggest a couple of ways:

the .onUpdate is called every tick, so you could put your code in there to see whether the mob is within range of the target position (or if too much time has elapsed, give up).  ForgeHooks.onLivingUpdate(this) might be a good spot.

 

Probably better: create your own AI task to do it.  See EntityAIMoveTowardsTarget for inspiration, also EntityMoveHelper.
