Bukkit.createExplosion(); Stopping blocks blowing up.

Ok so here's my question:
How can I make an explosion that doesn't hurt anyone or do any damage? I just need the velocity part of it.
Future thanks!

 

Look at EntityExplodeEvent and EntityDamageByEntityEvent

 

p.getWorld().createExplosion(<location>, null);
like this?

 

Oh sorry. I don't think I was very specific. I need to make an explosion using:
Bukkit.createExplosion();

 

Just play the explosion effect instead of making an actual explosion?

 

But he wants the velocity with it.

You could just check if the player was last damaged by an explosion and if it was just replenish the health back and for your block problem: Make a list of all the blocks that were destroyed by tnt explosions and after like 2 ticks restore all the blocks from the list back to it's original location.

Use these parameters to remove block damage
