You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? I just want to lerp the camera right to left or whatever position
What is the issue? İt doesnt work as it should it stays at the 2. values number(idk how to explain :Lerp(x, 0.5) it stays at the 0.5’s position
What solutions have you tried so far? I checked google and chatgpt but non of them worked
I dont see any reason for it to not work
local player = game.Players.LocalPlayer
local CharacterHandler = require(script.CharacterHandler)
local ThirdPersonCamera = require(script.ThirdPersonCamera)
local UIS = game:GetService("UserInputService")
local RunService = game:GetService("RunService")
local cameraOffset = CFrame.new(1.5, 0.5, 0)
local characterHandlerInstance
local function set_camera(char)
local Camera = ThirdPersonCamera.new(char)
char:WaitForChild("Humanoid").Died:Once(function()
Camera:Destroy()
end)
local currentCamera = game.Workspace.CurrentCamera
RunService.Stepped:Connect(function()
currentCamera.CFrame = currentCamera.CFrame:Lerp(currentCamera.CFrame * cameraOffset, 0.1)
end)
end
local function char_added(char)
set_camera(player.Character)
characterHandlerInstance = CharacterHandler.new()
local inventory = {
Primary = "",
Secondary = "Glock",
Melee = ""
}
characterHandlerInstance:loadInventory(inventory)
end
player.CharacterAdded:Connect(char_added)
if player.Character then
char_added(player.Character)
end
UIS.InputBegan:Connect(function(input: InputObject, gameProcessedEvent: boolean)
if gameProcessedEvent then return end
if input.UserInputType == Enum.UserInputType.Keyboard then
if input.KeyCode == Enum.KeyCode.One then
if characterHandlerInstance then
characterHandlerInstance:equipGun("Primary")
end
elseif input.KeyCode == Enum.KeyCode.Two then
if characterHandlerInstance then
characterHandlerInstance:equipGun("Secondary")
end
elseif input.KeyCode == Enum.KeyCode.Three then
if characterHandlerInstance then
characterHandlerInstance:equipGun("Melee")
end
end
if input.KeyCode == Enum.KeyCode.E then
cameraOffset = CFrame.new(1.5, 0.5, 0)
elseif input.KeyCode == Enum.KeyCode.Q then
cameraOffset = CFrame.new(-1.5, 0.5, 0)
end
end
end)
Please do not ask people to write entire scripts or design entire systems for you. If you can’t answer the three questions above, you should probably pick a different category.
try using TweenService instead of Lerp, it will be more guaranteed to work, that and you need the currentCamera’s mode to be correct so it’ll move, e.g set the camera’s CameraType to Enum.CameraType.Scriptable
Thank you for the reply! Im not using tweenService because I will add many positions and I dont want to set them hand by hand. Also I changed the camera type and it seems to do something! It does go to a position but not to the expected position I want
it’s because :Lerp() just gets a point between this position and another position by a fraction, say you have two CFrames, one is at 0, 0, 0 and the other one at 0, 0, 1, doing :Lerp(CFrame2, 0.5) on the first CFrame will most likely get you something like 0, 0, 0.5, now say CFrame2 was at 0, 0, 2, :Lerp() will get you something like 0, 0, 1, and having the second argument over 1 will break alot of stuff i think
local cameraTweenInfo = TweenInfo.new(5, Enum.EasingStyle.Linear) -- linear movement
local targetCameraCFrame = CFrame.new(0, 5, 0) -- this will move it 5 studs upward
local cameraTween = tweenService:Create(camera, cameraTweenInfo, {
CFrame = targetCameraCFrame
})
camera.CameraType = Enum.CameraType.Scriptable
cameraTween:Play()
Yes as I said Im not able to move the camera and its not usefull because it wont be able to change the position any time I want in the middle of the tween. Thats why Im trying to use lerping but it doesnt do anything. I dont want to use tween service
use RunService.RenderStepped or RunService:BindToRenderStep() instead of RunService.Stepped
your formula is also gonna be framerate-dependant so you might want to incorporate the deltaTime parameter of RunService.RenderStepped somewhere there
additionally, not sure whats going on in ThirdPersonCamera but that’s most likely conflicting with your code
(also, none of the RunService events will be trash collected so you have to manage the event connections by :Disconnect()ing them, likely whenever you create a new RunService connection. memory leaks are a pain :c)
local function set_camera(char)
local Camera = ThirdPersonCamera.new(char)
char:WaitForChild("Humanoid").Died:Once(function()
Camera:Destroy()
end)
local currentCamera = game.Workspace.CurrentCamera
local targetCFrame = currentCamera.CFrame:ToWorldSpace(cameraOffset)
RunService.RenderStepped:Connect(function(deltaTime)
currentCamera.CFrame = PositionLerp.lerpPosition(currentCamera.CFrame, targetCFrame, 0.1)
targetCFrame = currentCamera.CFrame:ToWorldSpace(cameraOffset)
end)
end
PositionLerp module I used ( I only wanted the position because camera angle and old angle glithces)
local PositionLerp = {}
function PositionLerp.lerpPosition(currentCFrame, targetCFrame, alpha)
local currentPosition = currentCFrame.Position
local targetPosition = targetCFrame.Position
local lerpedPosition = currentPosition:Lerp(targetPosition, alpha)
return CFrame.new(lerpedPosition) * currentCFrame.Rotation
end
return PositionLerp
but this time the lerping still doesnt work as it should how normally lerping works
what it should look like :
what it looks like:
lerp is acting like its not in a loop but it goes on the position for 1 time
It’s not easier if the code still doesn’t work… Also like @PuffoThePufferfish said, you should probably be cleaning up the connection if you’re not using BindToRenderStep.
Ok but does it really effect the gameplay if I dont clear the connection on the loop? It wont change anything. Also I tested the ThirdPersonClass doesnt change anything with the camera
Yes. Your FPS will lower every time you call the function due to the connections never being cleaned up. You never want to have a memory leak especially if it’s bound to the FPS
