Check if a helmet is broken and find out if a player is in a region

Hi Guys,
I know this Question seems stupid, but I really need this. I made a plugin which damages a helmet the hole time a player wears it.
1. Stupid thing is, that this

Code:

helmet.setDurability(helmet.getDurability() - 10);

will INCREASE the durability of the helmet. I thought "ok, change it to a plus" and it worked. But now, if the durability is "0" (i don't know i it's really 0). The item does not disappear, it just is there in the slot with negative durability. Then I wanted to check if the durability is 0, but it deleted the helmt all the time I waer it. So I'm asking, is there any way I can check if the helmet is broken? Or some other methods you use to decrease durability of an item? Thanks for helping

I just remembered the other Issue I have. I want to create a region (via a given radius) and then check if the player is in this region. I don't knwo how to do this, so can anyone please drop a bit of code to show me? Thanks you all for helping

Use extras, It has a region event in which you can do all this region creating shinanigans with lol.
And as for the helmet durability, instead of deducting from it, just try and set it at certain variables E.g 0.

Thanks for the help, but what is extras? I don't know what you mean.

 

Radius checking ? Did you ever heard the name Pythagoras ?

 

Durability works the other way round.
When something has full durability, its data is 0, and it increases as it gets "damaged".
To check if the item is about to break, Material has the method getMaxDurability(). So you'd go something like
if(helmet.getDurability() >= helmet.getType().getMaxDurability())

 

Extras is a library I made for plugin developers
It has functions you can hook into which'll help you check if a player is a cuboid, radius etc. Check it out here : http://forums.bukkit.org/threads/de...nced-methods-for-plugin-developers-953.26207/
