Jumping on a moving platform

[ituzis]

I’m trying to make it so when your standing on a moving platform, and you jump, you move with the platform and don’t fall off.

I couldn’t really find any post about it on the forum, and If I did then the post was probably years old.

This clip is from the game Desert Bus, you can see that when I jump, I don’t move back. This is exactly what I’m trying to replicate.

I’d appreciate some help! Thanks

Maybe you could try adding the velocity of the part the player is standing on to their AssemblyLinearVelocity while the player is on the platform?

Do you think there is other ways? I’ve tried this before. It sorta worked but was really buggy

[xAvrice (avrice)]

This post was linked in one of the topics you replied to recently. Have you tried the solution in here?
The solution seems to just calculate the difference in the platform’s previous and current CFrame and then apply that difference to the player (i think).

Jailbreak train platform system?

This is what I do and my version works pretty well. local Players = game:GetService("Players") local player = game.Players.LocalPlayer local RunService = game:GetService('RunService') local LastTrainCFrame local Function local Function2 Function = RunService.Heartbeat:Connect(function() --------------------------------------------------------------- CHECK PLATFORM BELOW local RootPart = player.Character.LowerTorso local Ignore = player.Character local ray = Ray.new(RootPart.CFrame.p,Vec…

Characters on Moving Platforms - Now Live

This will greatly improve official Roblox events, like the train issue in Jailbreak during the RPO event

Jailbreak train platform system?

Yep, i have no idea on what to do differently.

Yeah this has been a tough problem for a while. Multiple games have coded their own fixes to this, such as Jail Break with their trains.

A very easy fix would be to use the new character controller (currently in beta):

Continuing the discussion from New Humanoid Physics Controller - Beta:

@kleptonaut

Air control when jumping conserves momentum by default for a better experience when jumping between moving Parts.

You can check that out here:

The other option is to program something to modify the physics a little (such as adding a CFrame to the character based on the change of the CFrame of what they last stood on and the position of the character relative to that). There are probably some things the forum’s resources that have this behavior.

I’ve read basically all of these forums, their outdated and I’ve tried doing what they did and it just doesn’t work.

[ituzis]

I really tried this, and I think my issue was setting it up. I got really confused with it lol.

[BendsSpace]

It only works if the part is being moved with physics, if that helps.

It should work if the part is being moved by physics (and not the CFrame being directly modified).

Though it is in beta, so it might be hard to set up.

[ituzis]

Yea it was using velocity. still didnt change anything.

I think i just set it up wrong, but theres really no tutorials showing how to do it so.

You might find this article help:

Releasing Character Physics Controllers

NOTICE 2 This week, we are enabling fixes to the ClimbController, and enabling horizontal climbing capabilities. This will work by having the ClimbController read localized X and Z dimensions on MovingDirection, and they will be projected onto the climbed surface - just like how the GroundController works now. Previously it only looked at Z. This means if you’re using the example scripts provided in this post (or otherwise copying Humanoid.MoveDirection properties onto the ControllerManager),…

The one I sent said it was now outdated and to go to the article above.

Specifically you might want to try out this part:

@kleptonaut

Example Scripts

You can add these scripts to you experience to try using an avatar with the new physics controllers

InitializeCharacters.lua (1.5 KB)
This server script should be placed in ServerScriptService.
For every player that joins, it will set Humanoid.EvaluateStateMachine to false, and insert the necessary physics controller and sensor instances to the character model.

ControllerStateMachine.lua (4.3 KB)
This local script should be placed in StarterPlayer>StarterCharacterScripts.
This will manage swapping between basic Run, Jump, Climb, Freefall, and Swim states. It’s not intended to match exactly how the Humanoid handles these transitions, instead just covers basic input and movement.

I believe BendsSpace’s linked articles would be a better solution overall, but what was the problem you faced when you had tried the post I linked? I tested the script just now to make sure and it seems to work for me(although I just tested it with a single part, using the primarypart of a model in the script should also work).

ill try this out, thanks for the support
