[SCRIPT] Make something occur upon continue?

[Romulator]

Say that there is a ScriptArea which covers the entire map.
This means that no matter the player's position, he/she collides with it.
So if I add a CollideCallback between the player and the script, couldn't I code something like:

Code: (Select All)

void blackandwhiteeffect(string &in asParent, string &in asChild, int alState)
{
FadeSepiaColorTo(100.0f, 1.0f);
}

?

Edit: The reason I ask this before I implement is that I do not want the game to continuously do this if it will lag some of the underpriveledged computers.
