[1.11.2][Unsolved]Getting Villagers to Avoid a Certain Player

[OrangeVillager61]

I am working on a way to get villagers to run away from players that have a villager rep lower than negative 5. Currently, I am using a variation of entityAIAvoidEntity class, I've almost everything done except on how to recognize said hostile player.

 

I get an error if I use <T>getEntitiesWithinAABB as the original code has and I can't find an alternative.

 

Secondly, how to get a players name to compare with the villageObj's rep?

Okay, I've made the necessary changes but the villagers don't seem to run away from me when testing after murdering enough villagers next to a bunch of "houses".

 

I made a println after the worldisremote check but it doesn't println anything.

I tried to use the debugger but I get "URLClassPath.check(URL)line: not available" error and then the debugger tries to go through all of the null pointer exceptions with that.

Where do you get that error? What do you mean by " the debugger tries to go through all of the null pointer exceptions with that"?

I get said that nullpoinerexception when starting up MC and at "[14:16:24] [main/INFO] [LaunchWrapper]: Calling tweak class net.minecraftforge.fml.relauncher.CoreModManager$FMLPluginWrapper" I get that error, I press resume and I get that same error and it highlights arg0 and java.net.url = random numbers that go up (76, then 92, etc) everytime I press resume.

 

I'll try to get a screen shot.

Why did you put a breakpoint there then? Put a breakpoint on the first line of shouldExecute, nowhere else.

I did not put any breakpoints outside of shouldExecute(), I checked the breakpoint tab to confirm this. I did a copy stack and got the error list,
