Jetpack breaking on teleport?

Help and Feedback Scripting Support
#1

Greetings developers, recently I made a custom jetpack for my game and I have a problem with it. If you are flying and anyone uses something to teleport you [for example teleport command, or cuffs] your rotation breaks. Resetting the camera didn’t work and turning autorotate again didn’t work.

I just realized I set the name for velocity and gyro on the client side but that shouldn’t be a problem.

If your rotation breaks when a player gets teleported, the reason might be that you are persistently keeping the original rotation of the jetpack when it was first initialized, and then continuously referring to this state during flight. When the player gets teleported, the rotation context changes abruptly, which might cause unexpected behavior.

You could potentially solve this problem by always updating the base rotation (or the equivalent rotation variable in your script) every time the player gets teleported or cuffs are used.

Moreover, it is important to note that your script makes references to the HumanoidRootPart, which might not be there after teleportation. It is a good practice to make sure the references to important objects are up-to-date after the teleportation.

If you’re using a teleportation function provided by Roblox (like TeleportService), you might be able to use the Teleport event in order to reset the rotation and other relevant parameters.

Lastly, don’t forget to handle all edge cases that might arise when you teleport a player. This includes ensuring the player is not flying at the time of teleportation, and if they are, stop flying properly before teleporting.

If you could provide more details about how you are implementing the teleportation and how exactly the rotation “breaks”, I could give you more specific advice.

The advice given above is generic because without seeing the full context of your game or the teleportation/cuffing code it is hard to give a perfect answer. Hope it helps! :slight_smile:

Maybe use jetpack main storage as accesory, soo jetpack accesory will be the tool that you use in your game

#5

You need to disable BodyVelocity and BodyGyro on the jetpack but since they’re made on client you can’t do anything really besides firing client.

Well thanks for your time, this really helped!
