Solved Getting Error on EntityType().setHealth(1500);

Hey, wondering if anyone knew the cause of this error?

I try set the health of the entity (wither) to 1500 upon it being spawned.
However, it does not change the health and only gives me an error.

Here is the error:

Here is my code:

Code:

    @EventHandler
    public void onCreatureSpawn(CreatureSpawnEvent event) {
        if(event.getEntityType() == EntityType.WITHER) {
            event.getEntity().setHealth(1500);
        }
    }

The error occurs on this line:

Code:

event.getEntity().setHealth(1500);

Any help will be appreciated. Know what I should change it to ?

 

Carefully read your stacktrace... its not that hard to figure out.

 

event.getEntity().setMaxHealth(1500);

xD

Answers your comment? aha
Thanks. Normally error's are not that obvious.

 

IllegalArgumentException: Health must be between 0 and 300.0 < I wonder what the problem could be

There's already threads telling you how to read stack traces, read them.
