Is it possible to make a click to move?

It is actually possible to make this, and not as complicated as it might seem.

I've already made one of these myself in the past. You simply would need to find where the players mouse is, then make the green disc follow it.

To move the player, you just find the discs position, and tell the Humanoid to walk there. He's the script I came up with (Make sure this is in a LocalScript inside the PlayerGui) :

repeat wait() until game.Players.LocalPlayer
Plr=game.Players.LocalPlayer
repeat wait() until Plr.PlayerScripts
repeat wait() until Plr.PlayerScripts.ControlScript
Plr.PlayerScripts.ControlScript:remove()
Mouse=Plr:GetMouse()
repeat wait() until Plr.Character
Char=Plr.Character

local Bin=Instance.new("Message")
Bin.Name="LocalBin" --Makes the part a 'LocalPart' so only you can see it.
Bin.Parent=Char
Hover=Instance.new("Part",Bin)
Hover.Name=Plr.Name.."'s Hover Block"
Hover.FormFactor="Custom"
Hover.Size=Vector3.new(3,.2,3)
Hover.CanCollide=false
Hover.Anchored=true
Hover.BrickColor=BrickColor.new("Lime green")
Mouse.TargetFilter=Hover
Mesh=Instance.new("CylinderMesh",Hover)

function HoverUpdate(Mouse) --Sets up function to update position
	if Mouse.Target then
		X=Mouse.Hit.X
		Y=Mouse.Hit.Y
		Z=Mouse.Hit.Z
		X2=Plr.Character.HumanoidRootPart.Position.X
		Y2=Plr.Character.HumanoidRootPart.Position.Y
		Z2=Plr.Character.HumanoidRootPart.Position.Z
		DisX=math.abs(X-X2)
		DisY=math.abs(Y-Y2)
		DisZ=math.abs(Z-Z2)
		Distance=DisX+DisY+DisZ
		if Distance<=100 then
			Hover.Position=Vector3.new(Mouse.Hit.X,Mouse.Hit.Y+.2,Mouse.Hit.Z)
			Hover.Transparency=0
		else
			Hover.Transparency=1
		end
	else
		Hover.Transparency=1
	end
end

Mouse.Move:connect(function() --Updates disc position
	PlrMouse=Plr:GetMouse()
	HoverUpdate(PlrMouse)
end)

Plr.Character.Torso.Changed:connect(function() --Updates disc position
	PlrMouse=Plr:GetMouse()
	HoverUpdate(PlrMouse)
end)

Mouse.Button1Down:connect(function() --Moves character to target position
	if Mouse.Target~=nil and Hover.Transparency==0 then
		Char.Humanoid.WalkToPoint=Hover.Position
	end
end)

Mouse.KeyDown:connect(function(Key) --Replication of 'Jump' button.
	if Key==" " then
		local Space=true
		repeat wait()
			Mouse.KeyUp:connect(function(Key)
				if Key==" " then
					Space=false
				end
			end)
			Char.Humanoid.Jump=true
		until Space==false
	end
end)

So basically, this script will work to remove the controls, and to make the green disc for movement.

However, to make the Pathfinding, you'll need to work on that on your own. Sorry, I simply have no idea to how to use it.

You'll need nodes for whatever map you're using, and for the player to move to them if an object blocks the path that the character is currently walking on.

Anyways, I hope I helped. If you have any further questions/problems, please leave a comment below. Hope I helped :P
