In the first tutorial for GameMaker (catch the clown), I want to set the direction of the clown after the collision with the wall.

I want to do it by pressing the wall object with the mouse (before the collision, to set the angle parameter). For example by pressing only once the wall object it would change the clown's direction after collision by 45 degrees, twice by 90 degrees, and so on.

How can I do that?

Collision resolution - Character walking on ascendent ground

I don't know if the solution to this problem is quite straight-foward but I really don't know how to handle collision resolution on a game where the player walks on an ascendent floor which is not flat. How can the player position itself on the y axis depend on the ground x and z (opengl coords)?… >>> More

Hey all, I'm making a simple side-scrolling game, and I would appreciate some input! My collision detection system is a simple bounding box detection, so it's really easy to implement. However my collision resolution is ridiculous! Currently I have a little formula like this: if (colliding(firstObject… >>> More
Collision Resolution

I know quite well how to check for collisions, but I don't know how to handle the collision in a good way. Simplified, if two objects collide I use some calculations to change the velocity direction. If I don't move the two objects they will still overlap and if the velocity is not big enough they… >>> More

Update: Turns out it's not an issue with this code (or at least not entirely). Somehow the objects I use for keylogging and player automation (basic ai that plays the game) are being 'skipped' or not loaded about half the time. These are invisible objects in a room that have basic effects such are… >>> More

Where can I find a good tutorial to replicate Game Maker's surfaces and blend modes in XNA?

as seen on Game Development - Search for 'Game Development'
I know Game Maker's surfaces exist in XNA (It's more the othe way around, XNA's surfaces exist in Game Maker), same thing for blend modes, since (I think) they both use DirectX. This is the question: "Where can I find a good tutorial to replicate Game Maker's surfaces and blend modes in XNA?" I'm… >>> More
