Hurtworld Spawn items / objects

You can easily do this with the console. "Spawn Roach"

 

I've been looking at Noviet's Lootchest script for the last hour and half trying to figure out how I can edit it to spawn X other objects at designated zones or coordinates.

Unfortunately I'm not much of a coder - so perhaps someone else could take it upon themselves to write a simple, well commented script that has nothing but the basics of spawning one or several objects at one coordinate or either in a radius from a coordinate / inside a box made out of two coords.
And have them dissapear and respawn after x time / if picked up.
