cthug	Pretty: Any reason why you use drawline? I ported to freebasic aswell: #include "SDL/SDL.bi" #include "SDL/SDL_gfx_primitives.bi" #define Screen_X 256 #define Screen_Y 256 #define Depth 0 dim shared as SDL_Surface ptr video dim shared as integer x, y SDL_Init(SDL_INIT_EVERYTHING) video=SDL_SetVideoMode(Screen_X,Screen_Y,Depth, SDL_HWSURFACE or SDL_DOUBLEBUF) for x=1 to Screen_X for y=1 to Screen_Y lineColor(video, x, y, x, y, SDL_MapRGB(video->format, x, y, x)) next y next x SDL_Flip(video) sleep ' EOF --v

cthug	Some modification for xor: #include "SDL/SDL.bi" #include "SDL/SDL_gfx_primitives.bi" #define Screen_X 256 #define Screen_Y 256 #define Depth 0 dim shared as SDL_Surface ptr video dim shared as integer x, y SDL_Init(SDL_INIT_EVERYTHING) video=SDL_SetVideoMode(Screen_X,Screen_Y,Depth, SDL_HWSURFACE or SDL_DOUBLEBUF) for x=1 to Screen_X for y=1 to Screen_Y lineColor(video, x, y, x, y, SDL_MapRGB(video->format, x xor y, y xor x, x xor y)) next y next x SDL_Flip(video) sleep ' EOF --v BlitzMAX: Const Screen_X=256 Const Screen_Y=256 Const Depth =0 Graphics (Screen_X,Screen_Y,Depth) For X=1 To Screen_X For Y=1 To Screen_Y SetColor X~Y,Y~X,X~Y DrawLine X,Y,X,Y Next Next Flip WaitKey --v pic:

Hotshot	Any reason why you use drawline? I could either draw "drawline" or "drawrect" The first things that I didnt know is X~Y as I didnt think blitzmax could do ~ for such as things. Your code is interesting. How do you move Gradient like plasma in blitzmax?

cthug	I made an error; code should read: For X=0 To Screen_X For Y=0 To Screen_Y SetColor X~Y,Y~X,X~Y DrawLine X,Y,X,Y Next Next --v NOT For X=1 To Screen_X For Y=1 To Screen_Y SetColor X~Y,Y~X,X~Y DrawLine X,Y,X,Y Next Next --v as for "Gradient like plasma"; I dont know
