Hi

 

I'm having a bit of trouble seeing how your code is supposed to work.

As far as I can tell, you use onUpdate to see if any living entities touch the grenade (collide with the boundingbox), and when they do, apply a blindness effect and explode the grenade.

 

Is that what you intended?  And if so, what doesn't work?

 

-TGG

So you mean that my boundingBox is whenever the entity touched the grenade that is thrown ?

 

Im kinda confuse a little but what i want is when the grenade is thrown all entities in the area that seen the grenade will be blind

boundingBox is set by Entity#setSize(...).

I assume you don't want your grenade to be bigger, so I'd recommend using AxisAlignedBB#expand(double,double,double) on boundingBox.

By the way, EntityPlayer is not an EntityLiving in recent Minecraft versions, you may want to check for EntityLivingBase instead.

You will probably need a counter too, to avoid the grenade exploding in the player hands.
