ef_cloud;
Returns: N/A.
This constant is for use in the functions effect_create_above and
effect_create_below, and
will create a cloud effect as illustrated in the image below:
if !irandom(9)
{
effect_create_below(ef_cloud, random(room_width),
random(room_height), choose(0, 1, 2), c_gray);
}
The above code has a 1 in ten chance of creating a cloud effect of random size at a random position within the room.
