World2Screen without view matrix or rotation matrix

[skythekidfus]

How would I go about writing a world to screen function using only the following:

• My X, Y, Z
• Enemy X, Y, Z
• Camera FOV, Pitch, Yaw

All W2S functions I came by used some sort of a matrix, but the process I use doesn't have one.

The matrix stuff isn't "process dependent" it's maths and just consists of a few numbers depending on what you want to do. If you really want to understand it you'll have to do maths (a lot). Good luck.
