this basically does the following:
checks if there are shields remaining, if no, then the damage goes to HP
else it gets substracted from the shield, and if the shield is below 0, then destroys the shield


it is not super great as damage now doesn't "overbleed" through the shield; even if a 10 strength attack hits
an 1 strength shield, the shield still completely blocks it before being destroyed, but this whole
scene is just an effect demo package, so meh
