How to make a snake like movement

Help and Feedback Scripting Support
#1

So currently I want to make it where when you move, the rest of the body will follow, however I want it similar to slither.io where the rest of body doesn’t turn right away but it somewhat follows the path that you move in. I’m bad at explaining, basically I want a movement similar to Slither.Io. Any rough ideas on how I would do this?

How to inverse kinematic a snake model
#2

You’ll want to use inverse kinematics. It would work like so

You can use this simple module I made to solve an Inverse Kinematics set of parts.

local IKFramwork: table = {}

function IKFramwork.SolveIK(segments: table, startPart: BasePart, endPart: BasePart): nil
	local prevSegment: BasePart? = nil;
	for i = #segments, 1, -1 do
		local goalPosition: Vector3? = nil;
		local currentSegment: BasePart = segments[i];
		
		-- Set the goalPosition as the endPart if there was not a previous iteration
		if (not prevSegment) then
			goalPosition = endPart.Position
		else
			goalPosition = (prevSegment.CFrame * CFrame.new(0,0,prevSegment.Size.Z/2)).p
		end
		
		local startPositionOfThisSegment: Vector3 = (currentSegment.CFrame * CFrame.new(0,0,currentSegment.Size.Z/2)).p
		
		-- Set the CFrame from the goalPosition, facing the segment's current start position
		currentSegment.CFrame = (CFrame.new(goalPosition, startPositionOfThisSegment) * CFrame.new(0,0,-currentSegment.Size.Z/2)) * CFrame.Angles(0,math.pi,0)
		
		prevSegment = currentSegment
	end
end

return IKFramwork

Here’s a place file I made that uses it (originally used to solve someone else’s arm problem): IK test place.rbxl (182.3 KB)

Issue with this worm-like system?

Is there any way I could apply this to meshes?
