I get a "Wrong number of dimensions. Found: 'Colornumber'"

On line 194, in the first line of the very last sub.

What is the problem!? I cant work it out.

A cookie for anyone who can.

(Most of the code is not mine, I'm just attempting to learn SDL)

[/syntax]

pal() is being accessed inside a subroutine but it's not declared as shared, FB will only create scalar vars.

btw, that BMP loader probably won't work, due the way user types are packed, you can load a bmp on SDL by doing:

dim mybmpsurface as SDL_Surface ptr
mybmpsurface = SDL_LoadBMP( "filename.bmp" )

SDL_LoadBMP's prototype was included on version 0.10b.


EDIT: also, PSET, SCREEN are all reserved words now.

*Smacks head on desk*

how did i suddenly lose my ability to handle Shared vars?

Heh

also thanks for the info about the bmp loading, although it really was just an excercise, i didnt really need a loader

Where can i get a list of the routines in SDL?

At http://sdldoc.csn.ul.ie/

C-oriented only, may won't be too simple to "translate".
