ef_ellipse;
Returns: N/A.
This constant is for use in the functions effect_create_above and effect_create_below,
and will create an ellipse effect as illustrated in the image below:
effect_create_below(ef_ellipse, x, y, choose(0, 1, 2), make_colour_hsv(irandom(255), 255, 255);
The above code will create an ellipse effect with a random size and colour at the position of the instance running the code.
