Making players not be able to collide?

Hello! I am currently making an obby and wanted to do so that players cannot collide with each other (so they go through each-other's avatars). Does anyone know how to do this? Thanks!

You would want to use Collision Groups by using the PhysicsService

https://developer.roblox.com/en-us/api-reference/class/PhysicsService

and the PhysicsGroup:SetPartCollisionGroup() function

I am not good at explaining here but the two links should get you on the right track! Please accept my answer if it helped you out.
