Hi hello, I did my first mob for the mod and is working at the end.

 

But I have only one thing more for finish the mob... I would like to add to the mob custom jumps to move instead to travel following  lines. I would like to ask if there is any AI or function that I can use to tell to the mob to move using jumps.

 

Thanks.

Try looking at EntitySpider. They attack the player by jumping at them.
