Jumping Mob

[DoorCloser]

I need to create a jumping mob. So, basicly his AI is too jump on target when it gets as near, as code says. Else mob is just walking. That would be great if somebody have any ideas.

I just want my mob to LEAP or JUMP on me when it gets as NEAR as CODE says. OTHERWISE my MOB is just going to WALK! Here is the damn code.

I've MADE my MOB to PERFORM JUMPING ACTIONS, but he DOESNT WALK. I TRIED to USE the moveSpeed METHOD, but that DIDNT WORKS. It only READS moveForward and moveStarfing. MAYBE thats because of AIDISABLED. I havent enabled it's AI because code WOULDNT WORK! WHAT I SUPPOSE TO DO. HOW CAN I MAKE MY MOB TO PERFORM JUMP ACTIONS WHEN HE GETS AS NEAR AS CODE SAYS, BUT OTHERWISE MOB WILL JUST WALK AFTER ME!

 

CAN ANYBODY HELP!?

Don't spiders jump at you when they attack? Perhaps take a look at the spider classes to see how it is implemented there.
