While we developed this game, we encountered many game design problems. Players shoot without releasing the shooting button, and some approach the other without thinking or hiding (depending on the player's game style). We wanted to make the players to kind of dance in the arena. So we added some limitations to the game. The players now have a finite amount of ammo they need to refill if they want to continue shooting. So now the players have a target object to collect at the arena, and they try to move there without getting hit by their opponent.
But the problem is, How many ammo packs should be in the arena at each given time?
I was inspired by the Harris response calculation, but I improved it to work with more numbers and normalized.
So I took the product of all the players ammo amount and divided it by the average.
This thing give me something like this: (for 2 players)
