On night

I want to make, when night, players gains like nightvision, I have code, but I don't know where to write it, code:

Code:java

if(player.getWorld().getTime() == 13000){
player.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION, 600, 2));
}

Maybe this thing have specific event?

You could use a runnable to check the time every second, or whatever time interval you want.
This should help:

Wingas it doesn't unfortunately.
You can use a schedular though, it willk do the same thing.

 

any more answers?

 

There are many different approaches to this. But you should look into schedulers.

 

DannyDog uhhh, im new in scheduler, can you write an example?

 

Wingas
There's an example, sorry multiple examples, on here: http://wiki.bukkit.org/Scheduler_Programming

 

Gater12 I don't know which to use..

 

Wingas use a sync repeating task (.runTaskTimer()) with an interval chosen by you (say, every 5 seconds). In that task, check the time - if it's dusk (within the same time range as the interval you chose) then give the player(s) the night vision effect. Do the opposite if it's dawn.

 

I agree with DannyDog. The are more ways to approach this. I reccomend to start here: http://wiki.bukkit.org/Scheduler_Programming I also understand that you're looking for an example? Here's one:

Code:java

Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(this, new Runnable()
{
public void run()
{
// Do desired code here, and of course, define the Player above;
}
}, <The ticks, i don't know how many ticks a day has :P>();

Warning: May contain mistakes, written by hand!

 

How to get specific player for scheduler? or all players
