The Dink Network

I have these guys moving across the screen. If a condition is met, I want them to attack dink. but they continue until they reach the move destination first. How can I break the move() and start the attack ?
//
move(&current_sprite,6,700,1);
if(&evil < 10)
{
unfreeze(&current_sprite);
sp_target(&current_sprite,1);
}
//
