Question

I have a small problem with this method,
this is my code ( I have more code but this is the part that gives me errors)

void ranCol( SDL_Surface sprite[], SDL_Rect paste)
{

        SDL_FillRect(sprite[y],NULL,temp);
        SDL_BlitSurface(sprite[y],&paste[y],rScreen(),NULL);
}

I get 2 errors

error C2664: 'SDL_FillRect' : cannot convert parameter 1 from 'SDL_Surface' to 'SDL_Surface *'
error C2664: 'randCol' : cannot convert parameter 2 from 'SDL_Surface *[50000]' to 'SDL_Surface []'

Can anyone help me get this working?

EDIT: Here is the code incase someone wants to comile it

    void randCol(int times, SDL_Surface* sprite[], SDL_Rect paste)
{
    int unsigned temp = 10101;//seed
    for(int y = 0;y < times;y++)
    {
        temp = temp*(y+y+1);
        temp = (temp^(0xffffff))>>2;
        //printf("%x\n",temp);
        SDL_FillRect(sprite[y],NULL,temp);
        SDL_BlitSurface(sprite[y],&paste[y],rScreen(),NULL);
    }
}

You should always manipulate pointers to SDL_Surfaces… change your function to

void ranCol( SDL_Surface* sprite, SDL_Rect paste)

I am not sure where your [y] comes from! If it’s from an array of SDL_Surface, pass a single SDL_Surface as a parameter to the function, it will be clearer.

If you want to pass an ARRAY of items, use the following signature:

void ranCol(SDL_Surface* sprite[], SDL_Rect paste[])

But you will still need to pass your y in some way, either as a parameter or as a member / global.
