So I am using a pretty much unknown language to program my game: GML. If anyone knows the answer to my question, please keep it in as much math as possible to keep translation easy.
The variables are defined as follows:
drc = rotation counterclockwise from x to y
elev = rotation counterclockwise from x to z
The z axis is vertical in this situation.
If you prefer to have values for length, width, and height, here they are: 6 x 2 x 2. Length is on the x axis, width on y, and height on z.
