My first Plugin. But need help.

Alright so am starting to make my own plugin but i get this error Ive been using the Plugin tutorial on wiki and following the steps and reading and learning.And the plugin i want to make is [Killing the player]. I get this line in set health and i dont know why.

 

cruz2000 setHealth(0.0);
setHealth(0); will give you a warning but it will still work.

 

the line usually means that the method "setHealth" is deprecated. Deprecated means that some time in the future, bukkit will probably remove the setHealth method, and at that time any plugin using the deprecated method will no longer function properly.

Before they remove the deprecated method, bukkit will introduce an alternative method to accomplish the same task, and it will be the responsibility of plugin developers to update their plugins to use the new methods.

In this case of setHealth(0), using an Integer as the argument is deprecated, the preferred method uses a double instead: setHealth(0.0)

 

cruz2000 Try to use target.setHealth(target.getHealth() - target.getHealth());?

 

Why not just set it to 0 rather than making the server do a calculation (albeit simple)?

 

p.damage(p.getMaxHealth());

Use that? It will also do animation

 

Not necessary, just use 0.0 or 0D with the setHealth() method

 

Thank you all! helped . Very pleased with the help here! Thank you . You are all helpful! But one problem .
