Solved Editing this plugin to only remove buildings?

Hello there everyone, so a plugin made by LazerHydra called NukeWipe needs to be edited. He gave me permission and all so thats not a big deal.

Only thing that needs to be edited is the stuff that makes the explosion, and make it to where it only destroys all buildings but kills no players or animals in the process.

So just make NukeWipe not kill anyone when it wipes and make it to where it only removes buildings

Thanks in advance
