How to make a player collide with a wall, but other parts cannot collide with the same wall?

[TheOnlyJnockl]

Hello people reading this! I recently (for an obby) Need help figuring something out!

I need this rotating part to go through this cylinder in the way, but not the player, is there any way I can possibly do that?
I have tried making it can collide true and can collide false, but obviously that does not work.

Here is what happens with it being can collide true. The player can touch it, but the part glitches out and cant go through it.

Here is what happens when It is can collide false! The platform can move through it, but not the player!

You need to use collision groups.

First, set CanCollide on the spinning part to true.

Then, open the collision groups window, which is in the “model” tab.

This window should pop up.

Then, add two groups using the “add group” button at the bottom by entering the name and then pressing enter. I’m just going to name them Spinning part and Cylinder.

Then, select the spinning part with your mouse, and press the plus icon on the collision group while it’s selected. This will add the spinning part to that collision group. Then do the same for the cylinder.

Once the two parts are added to the two collision groups, uncheck the box that controls whether they collide.
