Preventing damage to a specified player in Bukkit?

Question

I'm trying to make a command that allows you to make any player invulnerable -- that is, god mode. This is my code so far (though it's all boilerplate) ``` @EventHandler public void onEntityDamage(EntityDamageEvent event) { if(event.getEntity() instaceof Player) { if(godModed.containsKey(event.getPlayer())) { //This is where I need the code to go - something to cancel the damage. } } } ``` `godModed` is a `HashMap godModed` which contains all the players who are currently godmoded. When they turn off godmode they are removed from the map. The command itself is working fine - I currently have it send a message to the player who triggered it, and I also have it add the player to godModed if they are not already on. However, I can't figure out how to actually prevent the damage to the player. I want to stop it completely, not just heal them back afterwards; while the latter might work, it could also lead to unforeseen consequences if other mods look at `onEntityDamage` to trigger things…

Accepted Answer

You will want to use `event.setCancelled(true)`.

If the code you have currently is working you must be using the old event API (and an old version of bukkit), I suggest you upgrade bukkit. Code using the new event API would look something like this:

```
@EventHandler
public void onPlayerDamage(EntityDamageEvent event) {
    if(godModed.containsKey(event.getEntity())) {
        event.setCancelled(true);
    }
}
```
