You will need to do a LUA script for this, a LUA can then be compiled into a .LUR which is how the scripts are. EX: The arcade race in the Boys' dorm is called ArcRace1.lur so when you want to play the arcade machine, the file ArcRace1.lur starts. So to make a LUA script start instead of the arcade race when you play the arcade machine, you compile a lua script to be a lur file then replace the arcade one (ArcRace1.lur)
So first go to your C drive (Open the file manager thingy) and create a new folder called "LUA" there, or anything you'd like. Now inside put the Bully LUA Compiler (Included here with attachment) then make a new .txt document and change it to be named "luascript.lua" (Yes take off the .txt part) then open it in notepad or better, notepad++.
Here's code for a LUA script to spawn a ped (Put it in your luascript.lua you just made.
The code was originally here but now an attachment to save room.
There is a note "The -- part" in there, that's where the ped spawns. It spawns at variables for X, Y, and Z. XYZ are variables you see above there. Change them to the co-ordinates you want to spawn in. (Search for a coord grabber if you need to obtain coordinates, there's one on Bully-Board by manman) the 176 you see before X, Y, and Z is a model number. 176 is Russell. Go into your objects folder, then open "default.ide" in notepad to view all model numbers. Put the model number for the desired character. The rest of the code you do not need to understand if all you want to do is spawn a ped. There is much more you can do with LUA: You should try to make some bigger mods with it to.
Your not done yet, open the "Scripts" folder and go into Scripts.img with the IMG tool (Google it)
