Making a creature move without animations

Help and Feedback Scripting Support
1

I’m making a script that moves a creatures legs (and other limbs like tails and arms in the future) and pull it forward its not working well and I don’t know how to iron it out:

Sure inch-worming is better than nothing but it can’t stand up or run
This is the very basic script:

				print("ONNN")
				script.Parent.Body.PrimaryPart.Pulling.Position = Vector3.new(CFrame.new(script.Parent.Body.PrimaryPart.CFrame.X + 20,script.Parent.Body.PrimaryPart.CFrame.Y + 20,script.Parent.Body.PrimaryPart.CFrame.Z))
				script.Parent.Body.PrimaryPart.Pulling.MaxForce = 400000000000
				for i,e in pairs(script.Parent.Supports.WalkingPairs.Number1:GetChildren()) do
					e.Value.Leg1.LegEnd.Foot.BaseOfFoot.PlantFoot.MaxForce = 800000000000
					e.Value.Leg1.LegEnd.Foot.BaseOfFoot.PlantFoot.Position = Vector3.new(e.Value.Leg1.LegSegment1.ConnectionStart.CFrame.X + e.Value.Leg1.LegEnd.Foot.Size.X*25 ,e.Value.Leg1.LegSegment1.ConnectionStart.CFrame.Y - e.Value.Info.HoldUpVal.Value,e.Value.Leg1.LegSegment1.ConnectionStart.CFrame.Z)
					e.Value.Leg2.LegEnd.Foot.BaseOfFoot.PlantFoot.MaxForce = 400000000000
					e.Value.Leg2.LegEnd.Foot.BaseOfFoot.PlantFoot.Position = Vector3.new(e.Value.Leg2.LegSegment1.ConnectionStart.CFrame.X,e.Value.Leg2.LegSegment1.ConnectionStart.CFrame.Y - e.Value.Info.HoldUpVal.Value,e.Value.Leg2.LegSegment1.ConnectionStart.CFrame.Z)
				end
				for i,e in pairs(script.Parent.Supports.WalkingPairs.Number2:GetChildren()) do	
					e.Value.Leg2.LegEnd.Foot.BaseOfFoot.PlantFoot.MaxForce = 800000000000
					e.Value.Leg2.LegEnd.Foot.BaseOfFoot.PlantFoot.Position = Vector3.new(e.Value.Leg2.LegSegment1.ConnectionStart.CFrame.X + e.Value.Leg1.LegEnd.Foot.Size.X*25 ,e.Value.Leg2.LegSegment1.ConnectionStart.CFrame.Y - e.Value.Info.HoldUpVal.Value,e.Value.Leg2.LegSegment1.ConnectionStart.CFrame.Z)
					e.Value.Leg1.LegEnd.Foot.BaseOfFoot.PlantFoot.MaxForce = 400000000000
					e.Value.Leg1.LegEnd.Foot.BaseOfFoot.PlantFoot.Position = Vector3.new(e.Value.Leg1.LegSegment1.ConnectionStart.CFrame.X,e.Value.Leg1.LegSegment1.ConnectionStart.CFrame.Y - e.Value.Info.HoldUpVal.Value,e.Value.Leg1.LegSegment1.ConnectionStart.CFrame.Z)
				end
				script.Parent.Body.PrimaryPart.Pulling.MaxForce = 0
				wait(2)
				script.Parent.Body.PrimaryPart.Pulling.Position = Vector3.new(CFrame.new(script.Parent.Body.PrimaryPart.CFrame.X + 20,script.Parent.Body.PrimaryPart.CFrame.Y + 20,script.Parent.Body.PrimaryPart.CFrame.Z))
				script.Parent.Body.PrimaryPart.Pulling.MaxForce = 400000000000
				for i,e in pairs(script.Parent.Supports.WalkingPairs.Number1:GetChildren()) do	
					e.Value.Leg2.LegEnd.Foot.BaseOfFoot.PlantFoot.MaxForce = 800000000000
					e.Value.Leg2.LegEnd.Foot.BaseOfFoot.PlantFoot.Position = Vector3.new(e.Value.Leg2.LegSegment1.ConnectionStart.CFrame.X + e.Value.Leg2.LegEnd.Foot.Size.X*25 ,e.Value.Leg2.LegSegment1.ConnectionStart.CFrame.Y - e.Value.Info.HoldUpVal.Value,e.Value.Leg2.LegSegment1.ConnectionStart.CFrame.Z)

					e.Value.Leg1.LegEnd.Foot.BaseOfFoot.PlantFoot.Position = Vector3.new(e.Value.Leg1.LegSegment1.ConnectionStart.CFrame.X,e.Value.Leg1.LegSegment1.ConnectionStart.CFrame.Y - e.Value.Info.HoldUpVal.Value,e.Value.Leg1.LegSegment1.ConnectionStart.CFrame.Z)
				end
				for i,e in pairs(script.Parent.Supports.WalkingPairs.Number2:GetChildren()) do	
					e.Value.Leg1.LegEnd.Foot.BaseOfFoot.PlantFoot.MaxForce = 800000000000
					e.Value.Leg1.LegEnd.Foot.BaseOfFoot.PlantFoot.Position = Vector3.new(e.Value.Leg1.LegSegment1.ConnectionStart.CFrame.X + e.Value.Leg1.LegEnd.Foot.Size.X*25 ,e.Value.Leg2.LegSegment1.ConnectionStart.CFrame.Y - e.Value.Info.HoldUpVal.Value,e.Value.Leg2.LegSegment1.ConnectionStart.CFrame.Z)

				end
				script.Parent.Body.PrimaryPart.Pulling.MaxForce = 0
				wait(2)

Is the script not going about this the right way? are there any resources that can help?

Looks like you are trying to use physics to move, The main issue is that roblox has rubbish friction so it wont stick to the ground and just swing the legs around.

This is why most just use animations or something similar and make it move another way.

I am actually pull on the main body to force it forward moving isn’t so much of a problem but I just need the legs to manage to stay down and move when it’s time as well as the main body to pull up.
