Projectile damage event and scheduler

Hi guys, I need some help here, The problem is the following :
I'm making a plugin that uses archery, and I don't know which event should I use,
EntityDamageByEntity or EntityDamageByProjectile, because they both may be called.

The second question is how to use the scheduler to create a delay (20 ticks = 1 second, this is all I know).
Thanks

 

1) It really all depends on what exactly you wish to do with the plugin. Are you going to be dealing with special types of arrows, or simple manipulations of damage?

2) (after creating a scheduler)

Code:java

 
scheduler.scheduleSyncDelayedTask(Plugin yourPlugin, new Runnable(){
       public void run(){
         //do delayed stuff here
       }
},<delay>);
 

So if if I wanted to delay a certain boolean from changing for 5 seconds:

Code:java

 
scheduler.scheduleSyncDelayedTask(plugin, new Runnable(){
public void run(){
certainBoolean = false;
}
}, 100);
 

 

Also when using the scheduler, make sure any variables you want to use are declared as final.

 

Well, be careful with this though. Since the moment you declare it final, it is not possible to change that variable. So if you were using a final location of a player, and delayed it by 5 seconds, it would use the location from 5 seconds ago (as opposed to the location of the player right then at that moment)

 

that's why you declare the player final since it isn't going to change =3=

 

And if they're a schizophrenic?

 

Then they probably shouldn't be playing minecraft.

 

Touché.

EDIT:
Imagine it...
Amazing architect one night, destructive griefer the next.

I'd imagine it would be a vicious cycle.

 

I understand about the first one,
The reason I need to use the scheduler is because I want to make a dealy between 2 arrow shots.

anyone pleas?
