I’ve made a rolling system, where the player can roll forwards.
To create the effect of them moving forward, I’ve tweened the CFrame of their character’s HumanoidRootPart. The problem is, the first time, the player just teleports - but every time after that, the tween works.
Here’s the code:
local ts = game:GetService("TweenService")
--indentation because it's in a function
local rootPart:Part = hum.Parent.HumanoidRootPart
local origin = rootPart.CFrame.Position
local direction = rootPart.CFrame.LookVector * 65
local params = RaycastParams.new()
params.FilterDescendantsInstances = hum.Parent:GetDescendants()
params.FilterType = Enum.RaycastFilterType.Exclude
local hit = workspace:Raycast(origin, direction, params)
local targetCFrame:CFrame = rootPart.CFrame + rootPart.CFrame.LookVector * 45.5
if hit then
targetCFrame = CFrame.new(hit.Position, rootPart.CFrame.LookVector)
end
local tween:Tween = ts:Create(
rootPart,
TweenInfo.new(
playAnim.Length / 2.85, --an animation length
Enum.EasingStyle.Sine, Enum.EasingDirection.Out
),
{CFrame = targetCFrame}
)
tween:Play()
tween.Completed:Wait()
The raycasting is there to stop them going through walls. I thought it might be relevant.
There are no errors or warnings in the output, and I’ve tried debugging with print statements.
local ts = game:GetService("TweenService")
-- Assuming 'hum' is already defined somewhere in your code
local rootPart = hum.Parent.HumanoidRootPart
local origin = rootPart.CFrame.Position
local direction = rootPart.CFrame.LookVector * 65
-- Create RaycastParams
local params = RaycastParams.new()
params.FilterDescendantsInstances = hum.Parent:GetDescendants()
params.FilterType = Enum.RaycastFilterType.Whitelist -- Change to Whitelist if you want to specify which objects to include instead of exclude
-- Perform the raycast
local hit = workspace:Raycast(origin, direction, params)
-- Calculate target CFrame
local targetCFrame = rootPart.CFrame + rootPart.CFrame.LookVector * 45.5
if hit then
targetCFrame = CFrame.new(hit.Position, rootPart.CFrame.LookVector)
end
-- Create tween
local playAnim = {} -- Assuming playAnim is defined somewhere in your code
local tween = ts:Create(
rootPart,
TweenInfo.new(
playAnim.Length / 2.85, --an animation length
Enum.EasingStyle.Sine,
Enum.EasingDirection.Out
),
{CFrame = targetCFrame}
)
-- Play tween
tween:Play()
tween.Completed:Wait()
Please could you point out what parts you changed? I saw you changed the RaycastFilterType, but Whitelist is deprecated and Exclude works fine because I need to not include the character and that’s it.
Do you have any idea how to fix it? I can’t yield the code because that would mess with the animation timing and the tween, because the animation plays on the client. Can you use ContentProvider:PreloadAsync() on an animation ID or not?
Edit: I tested with ContentProvider:PreloadAsync() and it didn’t work.
Edit 2: You’re completely right. For some reason, when debugging with print statements, I didn’t think of making it print the animation length. But, the first time, it outputs 0, then the actual animation length afterwards.
local players = game:GetService("Players")
local contentprovider = game:GetService("ContentProvider")
local player = players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
-- create the animation instance
local animation = Instance.new("Animation")
animation.AnimationId = "http://www.roblox.com/asset/?id=507771019" -- Roblox dance emote
contentprovider:PreloadAsync({animation}) -- Without this, the length printed was 0
local animationTrack = humanoid:LoadAnimation(animation)
animationTrack:Play()
print(animationTrack.Length)
This works better than my solution as long as it works, I was under the impression after reading their previous post that it didn’t work with animations, which was confusing, but yea anyways it’s better than checking each function call for if it’s over 0
You can use a fixed animation length instead of playAnim.Length, since diving isn’t one of those animations that tend to change over gameplay time. You’re also tweaking the value itself empirically with a divisor so it seems like you want it to stay at a consistent value.
Preloading should work on animations. It’s very likely an implementation error. See post below.
Interesting, I’ll have another look at it. It might be that I just put the desired length straight into the TweenInfo, like what @treebee63 said. Thanks everyone for the help
Yeah, like @treebee63 said, preloading worked - I did it slightly wrong. I made it print the length of the tween I wanted to play, and now it works just fine. Thanks for your help everyone.
