Agressive bats help

So I've been trying to make "Wisps". Basicly an invincible bat with a small slime on the back.
I got the damage from the bat to the slime etc working.
I now have a problem with making the bats attacking the player, I've extended the bat class with zombie class.
Now the bat is just spazzing around on the ground :/

Does anyone have a piece of code that does work with bats?
Would be greaty appreciated!

(And yes I know about the tutorial but that doesnt help this problem)

 

I will look into it.

 

make if player moves 6x6x6 radius around bat it targets it or somthing

 

I think he meant that bat targets player but it's not flying. Maybe try to combine bat's ai with zombie targeting.

 

I made a small project for this: https://github.com/Cybermaxke/Whisps

 

Cybermaxke Awesome, do they work? Also may I use some of the code for my project? (I'll credit you)

 

Yes, they are working.
And sure, you can use some of my code.

 

Cybermaxke Any chance of updating this? It seems like an amazing plugin.
