Im attempting to make a simple FPS viewmodel with dynamic movement, Ive started with tilting the Viewmodel based if youre moving left or right
It mostly works, as it tilts smoothly and returns back to normal as intended, but if I keep walking in a direction, it goes over the max I set?
Code for this:
RunService = game:GetService('RunService')
-- Var
Camera = workspace.CurrentCamera
Thing2Clone = ReplicatedStorage:FindFirstChild('GunTestBasic')
Player = script.Parent.Parent
Character = Player.Character
Humanoid = Character:FindFirstChild('Humanoid')
-- Init
Viewmodel = Thing2Clone:Clone()
Viewmodel.Parent = Camera
-- Tilt Variables
LastTiltCFrame = CFrame.new()
TiltCFrame = CFrame.new()
LeftMax = CFrame.Angles(0, 0, 10)
RightMax = CFrame.Angles(0, 0, -10)
function ViewmodelCalibration()
--////LEFT & RIGHT TILT////--
local Tilt = Humanoid.MoveDirection:Dot(Camera.CFrame.RightVector)
if Tilt < 0 then TiltCFrame = LastTiltCFrame:Lerp(RightMax, 0.0015)
elseif Tilt > 0 then TiltCFrame = LastTiltCFrame:Lerp(LeftMax, 0.0015)
elseif Tilt == 0 then TiltCFrame = LastTiltCFrame:Lerp(CFrame.Angles(0, 0, 0), 0.075) end
LastTiltCFrame = TiltCFrame
--////LEFT & RIGHT TILT////--
Viewmodel:PivotTo(
Camera.CFrame * TiltCFrame
)
end
-- Runservice
RunService:BindToRenderStep("ViewModel", 301, ViewmodelCalibration)
(theres also a few problems with the “Tilt” variable as itll sometimes go left or right even when im just moving forward)
For the interval if you want it to be more accurate with delta time use 1 - 0.0005 ^ dt you can adjust the speed it keeps by changing 0.0005 to be closer or further away from zero
CFrame.Angles measures in radians, not degrees, so a value of 10 is much higher than you might think it is. It can be fixed by putting math.rad around your values:
If you’re trying to make your character turn based on it’s momentum, you’ll need to:
Get the direction of movement
Get the momentum
Modify the momentum. Get rid of the Y value, and clamp the X and Z.
Multiply the direction by the momentum to get the x and z angles
Lerp HumandoidRootPart.RootJoint.C0 to be the originalC0 times CFrame.Angles(x,0,z), amount is dt times some speed value.
