Item Explosion Strange Error

[NeverMind]

When my throwable entity hits the something and explodes, I can't enter the area from the explosion. If I relaunch, all the damage I've done disappears.

Here is the code for the explosion:

 

this.worldObj.createExplosion(this, this.posX, this.posY, this.posZ, (float)this.explosionRadius , true);

Thanks, I did this, but now I can't see the projectile. It works, it makes the explosion and it hurts the enemies, but I just can't see the projectile.

No, that was one of the problems. It's fine now, I fixed it, thanks a lot, you helped me progress a lot.
