My setup:
Sidescroller type game. Character stays still while badguys whom are pinned to the Background move towards the hero. Background speed is set to move based off the heros move speed. On collision they stop and fight.
At high MS they will go through each other. I have tried setting them both to Solid but it didn't help.
I have 2 workarounds I will add, but I was curious if there was a better way to force stop them.
I am assuming they just move past the hero by the time the system checks aka a tick happens.
