I dont know why no errors in my classes all commands are working i cant get banned for dieing someone help

 

@Payless
What is line 117 of DeathBanListener? Imports and empty lines included.

 

Code:

this.deathWrappers.put(e.getEntity().getUniqueId(), new DeathWrapper(e.getEntity(), killer.getName(), deathBanTime));

 

@Payless
Please read this:
https://bukkit.org/threads/how-to-r...ubleshoot-your-own-plugins-by-yourself.32457/

 

I know how to trouble shoot i see where it tells me the line i check no errors

 

@Payless

These are the most important lines here. Something is null at line 117. Let me go through all the variables you referenced there:

• deathWrappers can be null
• The entity cannot be null
• Killer can be null
• death ban time cannot be null if it is an int.

Null check deathWrappers and killer. Post which one is null, and try initializing that variable.
