Friction/Ladder question

Hello, I’m working on a VR scene in which you play a kid in a playground
I’ve managed to craft collision boxes to the majority of my playground devices so that the player can move around the different attractions but I don’t know how to make slides/ladders work, I detached them from my main model and thought maybe there was an option to give their collision boxes different properties once they are sockets to the main model but I didn’t find such an option

would appreciate if someone can teach me how to do this or direct me to a resource that discusses this, thank you
