i am still using the dummies book. finally i got the loading of bitmap procedures correct(i guess). Create_Bitmap() Load_Bitmap_File() Load_Image_Bitmap() Unload_Bitmap_File() those r the above i follow in order. and those functions r taken from the dummies book as well. but i noticed that if those functions r setup in the Game_Init() part, the screen will flickers vigourously. so i tried in the Game_Main() part, it flickers less vigourously. so where should i place them? or am i missing something? or should spilt up the functions?
