To use that gani you could do something like this I think:

Save the script as mydamage.gani, then set
player.attr[10] = "mydamage.gani,100";
(10 can be any number between 1 and 30, 100 is the damage shown)
That is attaching the script to the player.

The player.attr[10] is then set to "" (empty string) again after a few seconds for clearing it, then when setting the player.attr[10] to "mydamage.gani,100" again later then onCreated() is called again.
