Can anyone please guide me onto the right track !. I''ve setup a global stucture: struct sprite { int max_speed; int anim_timer; int hide; int frame; int max_animate; SDL_Rect position; }; In my main windows loop, I initialize it like so: sprite fly; But I''d like to write a function that uses the structure, here''s what I''ve got so far. (but it doesnt work) void animation(sprite *spr) { spr.anim_timer++; } And I''ll calling the function like so: animation(&fly;; But when compiling I get this error: tut.cpp(137) : error C2228: left of ''.anim_timer'' must have class/struct/union type Help !, please !!!

You set up your parameters incorrectly. Post the line you use to call the function and the function definition. Also show the definitions for each of the variables that are passed in the funtion.
