You need hypertriggers:
http://www.staredit.net/index.php?tutorial=49http://www.staredit.net/index.php?tutorial=128One way to do it is to make your hypertriggers with "Wait 100 milliseconds" instead of "Wait 0" or "Wait 1". Then always add 1 to custom score.
Another way is to have hypers with "Wait 0", and then to make a trigger for a different player which always waits for 100 milliseconds before adding 1 to custom score.
Another way again is to have hypers with "Wait 0", and then to have a death counter/switch system that adds 1 to custom score every second trigger cycle (considering that one hyper trigger cycle on fastest speed is a little longer than 40 milliseconds).
