Weird, but also using X_SPRITE after a X_DRAWAXES makes all the X_SPRITE textures go blue...?

Even with... X_SETTEXTURE -1, -1...

Hopes this helps nail down the bug.

Thanks Gernot, Ive already got this working but no information is wasted information...

Im back to trying to fix my alphablending problems with a 3d particle system...

Anyway to make it a command line option or a run once only command? This way it can be an option for the end user?

Just a suggestion.

I use X_PRINT and X_DRAWAXES to show some debug info on my 3D objects in my scene. But some of the Axis's have been disappearing after I use X_PRINT?

Yep, all types should be treated the same (cept. array names and pointers).

Well at least I can go forward, Ill change it in the future if needed  

Why does this not work...

WHILE 1
myfunc(testvar)

FUNCTION myfunc: BYREF a AS Tmytype
a.foo$ = "Foo!"
ENDFUNCTION... probably me doing something silly? I want to pass a custom type 'byref'...?

Yep, I've been doing that... thanks any ways Gernot, I hope you have luck with the update.

Gif meh zeh guhn!

LOL, I went to babelfish (As I do quite a bit) to translate this from German to English... then I realised what it said... haha... doh!

ENDFUNCTIONThe above program does nothing but illustrate how I can not modularise types, globals and functions in the one file. I need this to post some stuff on the forums or use code between programs.

OK, Ill try and cut the code down and still show the error. As Arnold would say "I'll be Back!"

Im having a lot of trouble keeping my code in separate modules (files) together with there variables.

My library code is almost always the same.

Types
Global Variables
SubRoutines

I keep getting "TYPE  is not declared", Ive tried putting the variables in a function and calling it from the main program but Im still getting this error.

I mainly get this error if I try and read (from the main program)  a globally declared variable from a library

Any ideas?

Put a halt to this approach, saw a nice article on polar co-ordinates, Ill give that a bash instead

Yes, that's the problem, the camera vector seems to be based on a fixed set of axis and its not relative to the current camera vector... hmmm, knowing the problem does not help with the solution though.

Hmm, looking at it, It looks like the camera axis is rotating on a fixed axis, as opposed to an already rotated one (camera already moved...)... this is all very confusing, hehe

No luck Gernot.

Heres a little test program to illustrate the problem...
