Swap System
Story
I was chatting with Romek on MSN, looking for a system idea. Suddenly I come upon an idea; a swap system. I told Romek, asked him if it could be useful. And here is the result.
Implementing
Implementing is easy; just import the dummy and the trigger, and set the raw code in the code to match your imported dummy's raw code. (To view raw codes, press CTRL + D in object editor)
Why gamecache?
Because I didn't want to create a struct for just player id storing and speed doesn't really matter in such a system.
What is it?
This system registers when a player types -swaphero, puts up a dialog for the typing player which asks what player the typing player wants to swap with. When selected, a dialog is shown for the choosen player, which asks if he/she wants to swap with the typing player. If yes, replaces the hero of the typing player with the choosen player's hero. Of course items is transfered.
