Night Vision

I'm trying to make a night vision plugin but make it a special command just because i like commands that don't start with a slash.


Code:

If i have night vision then >nv will disable it but >nv wont enable night vision for some reason.

I'd assume you're doing this on the AsyncPlayerChatEvent, which is asyncronous, meaning you cannot change anything on the actual minecraft server in a thread-safe way. What you should do is schedule a synchronous BukkitRunnable and in that add the potion effect.

 

How do i schedule a synchronous BukkitRunnable?

 

@Nathan674329
Basically just a normal BukkitRunnable. Like this:

Code:java

new BukkitRunnable() {
    @Override
    public void run() {
       // Your code here
    }
}.runTask(mainClass)

 

thanks
