Okay let me break this thing down so you dont shoot yourself in the foot too hard. Here is the thing, when developing a game you need to keep in mind that these games is basically a Game Play wrapped in one BIG LOOP. Everytime the game play iterates it does one or more tests to see whether it should break out of the loop. The main loop basically says this. As long as the player has not been hit 3 times then keep looping. Thats the simplest description we can work with. So things you need are: Game Menu Game Play Game menu usually controls persistent data, configurations and initializes the game. Now the Game Play is the where the game loop loop goes. wihin the game loop you need (a must) some boolean variables to keep track of the state of the game such as. isPlayerDead = false and if true then it goes to Game over state and breaks out of the loop and back to Game Menu playerCanMoveright = true/false if true move x position a few units right if false then dont respond to commands to moe right. these tests can be that there is a barrier on the way etc other variable types could be instances of enemies, interactive objects, velocity, direction, weapons, ammo, point system, All these have to work together to get the simplest of games going. I hope i have added value in some way... am not very good in writting specs as I think more in code cheers Steve Obbayi SKYPE: sobbayi http://sobbayi.com http://blog.sobbayi.com ----- Original Message ----- From: "aki" <aki275@googlemail.com> To: "Skunkworks forum" <skunkworks@lists.my.co.ke> Sent: Wednesday, March 24, 2010 1:15:05 AM GMT -05:00 US/Canada Eastern Subject: [Skunkworks] Deriving Variables... For OOP programmers or general ones, what plan or methodology do you use for deriving variables ? Suppose this in design phase of the programme ( Before I do sniper, its "kungu-fu" skunk a simple 2D game similar to super mario to see if I can do this thing.... ) : Assume that I'm writing a game plan for a game called "kungfu-skunk" . I have created a requirements and design plan. Some of my basic requirements are these : - Player can move left / right of screen - Player can jump - Player can box and kick opponents I've already defined my Player Object, classes,methods and properties. What would be variables for Player and how can I derive these? I know one is position on screen. Rgds -- "..the game you imagined and the game that will result may not have a lot in common. Rapid prototyping is key..
