Have a question about making a script

I have been designing and spawning weaponcrates tonight, but my co-gamers can't see those. Wondered how this was possible exactly (just beginning with all this stuff, so might bemissing something obvious here?)

And I was also wondering if it was possible to spawn a pitched tent, packed with the goodies I code in? Or would this also never be seen / be usable for my co-gamers? Cause then it would be pointless. "hey guys I've set up the camp.." o'rly

Thanks.

Also, AFAIK, it isn't possible to actually spawn an already set up tent.
