I have a BUNCH of bumpers of four types bounceUp, bounceDown, bounceLeft, bounceRight. during a collision which you hit determines the bounce so they always do the same thing so here’s my question…

can i just name every bounceUp instance the same thing and then just add that one instance name to the list the collision detector checks???

i just dont wanna go through and name a hundred each of bounceUp s and bounceDown s individually as the potential for screaming increases proportionally…
