Here is my source code. I am really new at programming so ANY help that could assist would be awesome.

//Several "fish" sprites move once across the screen and user must "catch" them with the net, which is the mouse clicking on them.
//COMMENTS
//I have not been able to figure out how to include the catching of the fish and the keeping track of total points, which is what I am going to have in the final program. I also plan to make the fish look more fish-like, perhaps with .GIF's if making a complicated fish exclusively with C++ coding is too complicated.

void Fish::draw ()

setfillstyle (SOLID_FILL, COLOR (red, green, blue));
fillellipse (x, y, 16, 8);
//These lines are meant to color in the eye for the fish.
setcolor (BLACK);
setfillstyle (SOLID_FILL, BLACK);
fillellipse (x+6, y-2, 4, 4);
}

The window opens but the fish do not appear. I am trying to solve that problem before I focus on making it so when a fish is clicked it changes into a skelleton. If anyone feels like helping I would be indebt for eternity.

Game Programming is EASY. Introducing Graphics and mouse support is also simple.
