the reason im asking for help is on my map a placed a sword. I set the respawn to 180 but the sword spawns every 10 to 15 seconds. If any one knows what to do could u help me
You probably have the run-time minimum set to a number higher than 0. Set that to zero and your respawn should work the way you want.
Sword spawns are always weird, on the default pit there seems to be 3 swords at once sometimes. Just delete it and put it back. if that doesn't work, try using a shotgun or maybe mauler if possible within your map.
