rotation

I'm trying to add a projectile system like the projectiles in Realm Of The Mad God. (YouTube it to see what I mean)

These projectiles seem to move according to their rotation perfectly and can have nearly any rotation. They also have near perfect hitboxing.

What's the maths behind this? My Game works on an integer-based coordinate system, but at the moment projectiles can only shoot either 0, 45, 90, 135, 180, 225, 270 and 315 degrees.

I have implemented a physics engine based on the concepts in the classic text Advanced Character Physics by Thomas Jakobsen. Friction is only discussed very briefly in the article and Jakobsen himself notes how "other and better friction models than this could and should be implemented." Generally… >>> More
Approximating walking physics via simpler sliding physics

I am modeling walking insects. I implement them as cuboids and use forces (including friction and drag), to control motion. However, the movement characteristics of this 'sliding box' physics don't match those due to a legged creature. For example, legged creatures near-instantly accelerate to… >>> More
Sharing data between graphics and physics engine in the game?

I'm writing the game engine that consists of few modules. Two of them are the graphics engine and the physics engine. I wonder if it's a good solution to share data between them? Two ways (sharing or not) looks like that: Without sharing data GraphicsModel{ //some common for graphics and physics… >>> More

If anybody has dealt with a similar situation I'd be interested in your experience/wisdom, I'm developing a 2D game library in C++, I have game objects which have very basic physics, they also have movement classes attached to differing states, for example, a different movement type based on whether… >>> More

Good afternoon, Is there a way to split data from one row and store to separate rows?

For example I have a file similiar to this: Crs:Sn… >>> More

Need to translate a Rotation Matrix to Rotation y, x, z OpenGL & Jitter for 3D Game

I am using the Jitter Physics engine which gives a rotation matrix: M11 M12 M13 M21 M22 M23 M21 M32 M33 And I need it so OpenGL can use it for rotation GL.Rotate(xr, 1, 0, 0) GL.Rotate(yr, 0, 1, 0) GL.Rotate(zr, 0, 0, 1) Initially I Tried xr = M11 yr = M22 zr = M33 [1 0 0] [0 1 0] [0 0 1] Which… >>> More
Finetuning movement based on gradual rotation towards a target
