This might sound really bad for anyone who knows me but I simply can't remember the system on getting a certain amount of minerals and a certain amount of experience per kill for my RPG. I also want to have it where if you kill 1 Zergling in this case, you get like 2 minerals and 2 experience, while if you kill a hydralisk you get 5 minerals and 7 experience. I know this is easy since I knew how to do it awhile ago, but it has completely left my mind at this point...

There are multiple methods of doing Kills to Cash, all of which are shown here: http://www.staredit.net/wiki/Kills_To_Cash, be sure to check the wiki before posting.

If you don't have the player killing massive amount of units at once(more than one unit killed in less that 1/8th of an in-game second) then the third method should work perfectly for you, is your map multiplayer?

Yes it is multiplayer... 4 players to be exact... And sorry for not checking the wiki. I only was looking at the tutorial database... Guess I should have kept on reading. Thanks for the help Falk...
