Power Ups

#1 But any other power ups ideas and how to put them into the software are accepted.

#2 Maybe have a count of how many are in the world at a time, and once its gone, say out of ammo or lost off the side of the edge, set a schedule for 5 mins or however long? Just an idea.

#3 My one up code

       if(isObject(%effect))
	       %effect.schedule(1500, "delete");

     }
}

the effecs are just particles that appear when you pick it up, not sure about the timed thing, maybe change it in item.cs to where it takes longer o respawn?

#4 Thanks this work as my base of what the power up looks like. However, how am I to combine this script so that once they pick it up they get say a weapon that changes damage, range and area affect. Even after that how do I have the power-up itshelf and the upgrade have separate times? Once I get these my project should be finished.

P.S. As some of you may have thought I have just started this program and know only the very basics.
