If it is, then I minus the current X location with 5. If the Left key is pressed, I checked if the object is still currently inside the visible boundaries of the screen. After this, I started a Select Case statement determining which key was pressed. The Y location means Up or Down location. This is the movement/collision detection code of my Player class: gravity.y gspeed speed.y+gravity.y t (position.x + direction.x speed.x deltaSeconds, position.y + direction.y speed.y deltaSeconds) for (int i (int) Math.round (position.x / 32) - 2 t i < (int) Math.round (position.x / 32. The X location is the Left or Right position. This is pretty implementation dynamic dispatch for multiple types, as opposed to how standard C++ often is implemented with a single dimensional jump table for the virtual keyword. I'm using a tile based collision, but when the game is lagging (the lag isn't the problem) the collision fails and the player falls through tiles. However some of the entries are just duplicates where the two types are swapped. This style makes you code an N^2 number of functions, where N is the number of different entity types that participate.

Soon I’ll post game examples showing how to use this method and others collission detection methods. The idea is to store the identity of each entity as an integer, and use this ID to index into a virtual table of function calls.

It sounds to me like you could make use of a 2D jump table.
