1.12.2 - Can't get spellcasting & fireballing entity working correctly


ZombieEnderman5
 Share

Recommended Posts

As you can see in the title, my entity isn't working correctly. 1 in 3 of them are spellcasters; the other 2 spit fireballs like a Ghast does. Something to do with my SPELLCASTER property seems to be the problem; it's as though it's never set to true for my AI, but the entities themselves render correctly. (They render differently if they're spellcasters than they do if they use fireballs.) Entire entity class code below:
