| :) in 3D only need 2 or 3 angles?|
i make missiles, and use deltayaw & deltapitch..
is the same concept, no?
| It is the same concept as deltayaw. I only wrote it cos someone asked me to but it's useful if your doing a 2d in 3d game using just the x + y axis instead of x + z axis. I use it myself for this purpose. |
