ABSTRACT
The basics of platform games Platform games involve two fundamental concepts. First, user control of a sprite character, which can usually perform several actions: walk, run, jump, fall and so on. Second, collision detection to ensure that the character remains anchored to the world that is presented to the player. Both parts of creating a platform game need careful coding to ensure success. You may prefer to start with the collision testing or with the user control; either way they are two separate problems and should be tested and debugged separately as far as possible. We will start with the problem of user control.
