How to change the player's gravity only on specific parts

#1

I would like to create centrifugal gravity for a randomly-generated space station survival game made by my friend avasyz called “Seraphyra,” inspired by Doors, Alien: Isolation, Ultrakill, Cyberpunk, and more. I have tried egomoose’s gravity controller script, but it changed the gravity on every part and the scripting was barely understandable, so I did not know where and how to effectively alter the script.

Hey,

Hope you’re doing well.

Would you be able to provide the script that detects the change with a reference to the object (the part) that it obtains the attributes from? I did see you mention that you don’t know which script controls it, so if you’re unable to locate it - then just send the appropriate scripts through.

#3

here are the script models I used:

replicated storage scripts: (I tried editing the “GravityController” module)

starter character scripts:

starter player scripts:

The GravityController script has the collider part and is involved in changing the gravity.

#4

I think you’re best option is to add a vectorforce to the parts of which gravity you want to change on the y axis.

#5

I think this is the function EgoMoose uses to get the colliding parts. It is found in the GravityController module.

function GravityController:IsGrounded(isJumpCheck)
	if (not isJumpCheck) then
		local parts = self.Floor:GetTouchingParts()
		for _, part in next, parts do
			if (not part:IsDescendantOf(self.Character)) then
				return true
			end
		end
	else
		if (self.StateTracker.Jumped) then
			return false
		end
	
		-- 1. check we are touching something with the collider
		local valid = {}
		local parts = self.Collider:GetTouchingParts()
		for _, part in next, parts do
			if (not part:IsDescendantOf(self.Character)) then
				table.insert(valid, part)
			end
		end
		
		if (#valid > 0) then
			-- 2. do a decently long downwards raycast
			local max = math.cos(self.Humanoid.MaxSlopeAngle)
			local ray = Ray.new(self.Collider.Position, -10 * self.GravityUp)
			local hit, pos, normal = workspace:FindPartOnRayWithWhitelist(ray, valid, true)
			
			-- 3. use slope to decide on jump
			if (hit and max <= self.GravityUp:Dot(normal)) then
				return true
			end
		end
	end
	return false
end
