Currently making a tower defense game where units can move. Units have a mode called “Anchored” mode which makes units move around in a small area. How i do it is i clone a part and position it on the humanoid root part. Then a script gets the random x and y value of the parts position and moves the unit to that position every few seconds. The moving is completely fine, except that units dont turn.
Anyone know how to fix this?
Forgot to give the script.
module.ChangeMovementMode = function(unit, movementValue, mode, defaultWalkSpeed)
if unit and unit.Parent ~= nil then
print(mode)
if mode ~= "Anchored" and mode ~= "Explorer" and mode ~= "Patrol" and mode ~= "Sentinel" and mode ~= "Command" then return warn("Anti Cheat started") end
if mode == "Sentinel" then
end
if mode == "Anchored" then
local AreaPart = RS.UnitHandler.AnchoredModeArea:Clone()
local height = (unit.PrimaryPart.Size.Y / 2) + unit["Left Leg"].Size.Y
local unitPosition = unit.PrimaryPart.Position
AreaPart.Parent = workspace.Areas
AreaPart.CFrame = CFrame.new(Vector3.new(unitPosition.X, unitPosition.Y - height, unitPosition.Z))
local boundaryCFrame = AreaPart.CFrame
local boundarySize = AreaPart.Size
local boundaryMin = boundaryCFrame.Position - (boundarySize / 2)
local boundaryMax = boundaryCFrame.Position + (boundarySize / 2)
repeat
local targetPosition = Vector3.new(math.random(boundaryMin.X,boundaryMax.X), unit.PrimaryPart.Position.Y, math.random(boundaryMin.Z, boundaryMax.Z))
local path = PFS:CreatePath()
path:ComputeAsync(unit.PrimaryPart.Position, targetPosition)
local wayPoints = path:GetWaypoints()
for _, waypoint in wayPoints do
if movementValue.Value == "Anchored" then
unit.Humanoid:MoveTo(waypoint.Position)
unit.Humanoid.MoveToFinished:Wait()
else
return
end
end
local waitTime = math.random(1, 4)
task.wait(waitTime)
until movementValue.Value ~= "Anchored"
end
end
end
the commented line i gave you should make the humanoid look at the current waypoint
for _, waypoint in wayPoints do
if movementValue.Value == "Anchored" then
unit.Humanoid:MoveTo(waypoint.Position)
--unit.HumanoidRootPart.CFrame = CFrame.lookAt(unit.HumanoidRootPart.CFrame, CFrame.new(waypoint.Position))
unit.Humanoid.MoveToFinished:Wait()
else
return
end
end
I’ve tried this already, since the way point is on the ground the NPC will turn its body and will just fall over.
hmm, maybe use the waypoints position, but set the Y position of it to the unit’s humanoidrootpart?
and THEN make it look at it?
sometihng like this
-- the math i'm doing here very likely won't work, i'm just giving you an idea
local pointToLookAt = waypoint.Position + Vector3.new(0, rootPart.Position.Y, 0)
rootPart.CFrame = CFrame.lookAt(rootPart.Position, pointToLookAt)Instead of looking down it looks up for some reason. Really thought this would work but now I’m confused.
i assume you just CnP’d the codei gave you, i’m not sure ifthat’ll work
i think something like this should work:
for _, waypoint in ipairs(wayPoints) do
if movementValue.Value == "Anchored" then
local rootPart = unit.HumanoidRootPart
-- create a targetPosition variable, that uses the waypoint's X and Z positions, but the Y of the root parts
local targetPosition = Vector3.new(waypoint.Position.X, rootPart.Position.Y, waypoint.Position.Z)
-- then just simply make it look at that target position and walk towards it
rootPart.CFrame = CFrame.lookAt(rootPart.Position, targetPosition)
unit.Humanoid:MoveTo(waypoint.Position)
unit.Humanoid.MoveToFinished:Wait()
else
return
end
end
but also, just a question
since the movement value is “Anchored”, is the actual unit anchored aswell?
i assume it is, since the unit is just kinda sliding across the ground and not even rotating (unless .AutoRotate is off)
No I didn’t CnP the code and no the unit isn’t anchored, i just thought it was a cool way to call the movement mode where the unit only has a small space to walk around.
After trying out your code again it got a bit more confusing, the rootPart was nil. Idk what happened but when it enters the for loop the unit.PrimaryPart just becomes nil.
weird… the unit should be turning around if it’s not anchored
whar???
possessed code 
i actually have no idea why that is
On the first loop the rootPart is fine but after the second loop it just completely breaks.
i added the index so its clearer
damn, honestly i have no idea
ask ai, but at the same time, what error does it give out?
I just somehow fixed it by moving the root part out of the for loop. That problem is solved but the main problem is still not fixed, the NPC just gets teleported to 0, -1000000, 0
DAMN
okay i seriously have no idea D:
i TRIED
try playing around with the rootPart.CFrame, maybe the first parameter somehow breaks it
i’ll be lurking in here incase you get a revelation, will try to help
instead of doing the cframe thingy EXACTLY like that you just have to have the y value in the cframe positioning be the same as the waypoint’s y value
the most convenient method im looking at it here would be
also make sure cframe.lookat has 2 vector3s as inputs because thats what it expects (to my knowledge)
unit.HumanoidRootPart.CFrame = CFrame.lookAt(unit.HumanoidRootPart.Position, CFrame.new((waypoint.Position*Vector3.new(1,0,1))+Vector3.New(0,unit.HumanoidRootPart.Position.Y,0))
edit: made a mistake, corrected it
shouldn’t you be adding only the Y position of the root part, rather than the entire cframe of it?
i like the approach you took with the multiplication, wouldn’t think of that
no, because if the y axis of the hrp and the y axis of the waypoint were both 100, it would add to 200
Tried and still no. The unit just dissapears and goes to 0, -100000, 0
what do you mean you removed the root part out of the loop
