I am making a mod just now and I'm stuck at one line of code. Basically I want my mob to explode if it is in combat and its health <10

I thought something like:

 

public void onUpdate()

If {entity.health>20

then

{ boolean flag = this.worldObj.getGameRules().getGameRuleBooleanValue("mobGriefing");

 

                  this.worldObj.createExplosion(this, this.posX, this.posY, this.posZ, (float)(this.explosionRadius * 5), flag);

                 

Also, my java knowledge is still not perfect. I occasionally keep using BASIC language instead. lol!

Sorry for all the extra posts:

I believe that code is wrong as I do not have explosion radius set up. I grabbed some of the from the creeper properties.
