The title says it all. So basicly I need help making specific objects to only be able to collide with a specific model / group of parts. The reason why? Thats a story for another time.
You can make use of Collision Groups via PhysicsService or the collision group editor in studio.
To find the Collision Groups editor in studio, go to models and look for “Collision Groups”
An example of coding a collision group would be like this
local PhysicsService = game:GetService("PhysicsService") local CollisionGroup = PhysicsService:CreateCollisionGroup("CollisionGroupName")
To make two groups not collide with each other, do this
false to make them non collidable or true to make them collidable
To give parts a collision group, you could use this method
for i,v in ipairs(Model:GetDescendants()) do if v:IsA("BasePart") then v.CollisionGroupId = PhysicsService:GetCollisionGroupId("CollisionGroup") end end
It is important to remember that there is a max amount of collision groups which is 32, it is best to wrap code that creates collision groups in a pcall. Also collision groups cannot have the same name.
What do you put in the quotation marks?
The name of the collision group.
Is 32 the max per game? Or per group of parts?
The limit for collision groups is 32 per game. You can check with this function
