FreeGlut

Yes I agree Kent. Your strategy for static initialisation, involving a glut function is the correct way to do it.

Statics are assigned values at the start of the program (zero or null by default). And it is not safe to make a Glut call at this stage, before Glut is set up.

So a one-shot block is required:

Code: OxygenBasic

1.  
2.         'statics always initialised to zero at start of prog
3.        '
4.        static sys lastTime,loops,once
5.         static GLfloat fps
6.         '
7.        'one shot initialisation
8.        '
9.        if not once then
10.           ' this is assigned once
11.           lastTime = glutGet GLUT_ELAPSED_TIME
12.           once=1 'no repeat
13.        end if
14.

I like having the once flag near the routine instead of as a global as I had it. Good idea and thanks!
