(I’m really tired of this issue but it’s been annoying me for hours and I can’t find my logic error. Thought I’d post it here.)
Hello,
I’ve got a ziplining system that works moving the character, but always moves the camera to an odd location.
Video showing the issue:
Here’s my script:
local function processZipline(timeInSeconds:number, targetPos:Vector3, cancel: boolean?): nil --move the root part
if cancel then
tween:Cancel()
return nil
end
local cam = workspace.CurrentCamera
local camRotation = CFrame.fromEulerAnglesXYZ(cam.CFrame:ToEulerAnglesXYZ())
local hrpRotation = rootPart.CFrame - rootPart.CFrame.Position
local camOffset = cam.CFrame.Position - rootPart.CFrame.Position
if db2 then return nil end
targetPos += (rootPart.CFrame.LookVector * 2)
--set position
local targetCFrame = CFrame.new(targetPos) * hrpRotation
local camTargetFrame = (targetCFrame + camOffset)
--set up the tween
local info = TweenInfo.new(timeInSeconds, Enum.EasingStyle.Linear, Enum.EasingDirection.Out)
--create rootPart tween
tween = ts:Create(rootPart, info, {CFrame = targetCFrame})
--create camera tween
camTween = ts:Create(cam, info, {CFrame = (camTargetFrame + camOffset)})
--stop current animations
for _, anim in next, animator:GetPlayingAnimationTracks(), nil do
anim:Stop(0)
end
--move rootPart to start offset
rootPart.CFrame = CFrame.new(rootPart.CFrame.Position + (rootPart.CFrame.LookVector * 3)) * hrpRotation
--play tween
tween:Play()
camTween:Play()
track:Play()
playing = true
--wait until tween completes
task.wait(info.Time)
--stop animation
track:Stop(0)
--cleanup after tween
if tween then
tween:Destroy()
camTween:Destroy()
end
playing = false
db = false
camTween = nil
tween = nil
db2 = true
task.wait(1)
db2 = nil
end
Any help is appreciated, this issue is really annoying me now. Also sorry for the lack of commenting, I normally comment more but I’m just trying to fix this before I fully comment it.
More information like whether or not you use a custom camera system or you’re just looking for a specific effect could help.
Though my first theory could simply be the position you’re tweening to being other than what you expect or intend. Try printing out your final destination’s CFrame or creating a part at that location.
A few things like the camera’s offset being derived from the CFrame could be an issue with the rotation of the camera.
I put a part at the destination location and it’s always at an odd position. The purpose here is when I tween the HumanoidRootPart, the camera is always jittery so I decided to tween that as well, which was all working fine in first person because I was only tweening it to the same position. It’s only when I tried to account for the camera’s distance from the HumanoidRootPart that this issue started occuring.
I know it’s an issue with the target calculation somewhere, I just can’t figure out where. I’m using no custom camera system, just a tween.
Maybe a more simple fix would be to create transparent boxes just for the camera tween.
Tween between them two just as you have placed them including orientation.
That would make no difference, I would still need to calculate the target position and orientation which I am already doing. It would just add the extra hassle of making parts there, and as I previously said, I’m pretty sure the issue is somewhere in my calculations.
local TweenService = game:GetService("TweenService")
local TweenInfo = TweenInfo.new
local ts = TweenService
local function processZipline(timeInSeconds: number, targetPos: Vector3, cancel: boolean?): nil
if cancel then
if tween then tween:Cancel() end
if camTween then camTween:Cancel() end
return nil
end
local cam = workspace.CurrentCamera
local camRotation = CFrame.fromEulerAnglesXYZ(cam.CFrame:ToEulerAnglesXYZ())
local hrpRotation = rootPart.CFrame - rootPart.CFrame.Position
local camOffset = cam.CFrame.Position - rootPart.CFrame.Position
if db2 then return nil end
targetPos += (rootPart.CFrame.LookVector * 2)
local targetCFrame = CFrame.new(targetPos) * hrpRotation
local camTargetFrame = (targetCFrame + camOffset)
local info = TweenInfo(timeInSeconds, Enum.EasingStyle.Linear, Enum.EasingDirection.Out)
tween = ts:Create(rootPart, info, {CFrame = targetCFrame})
camTween = ts:Create(cam, info, {CFrame = camTargetFrame})
for _, anim in next, animator:GetPlayingAnimationTracks() do
anim:Stop(0)
end
rootPart.CFrame = CFrame.new(rootPart.CFrame.Position + (rootPart.CFrame.LookVector * 3)) * hrpRotation
tween:Play()
camTween:Play()
track:Play()
playing = true
camTween.Completed:Wait()
tween.Completed:Wait()
track:Stop(0)
if tween then tween:Destroy() end
if camTween then camTween:Destroy() end
