Grab Mechanic difficulties

[Seriphinee (AxeEater)]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve?
   I’m working on a simple grab mechanic (similar to what Lumber Tycoon 2) has. For this I’m taking advantage of the align position instance, and I’ve been happy with my results so far.

2. What is the issue?
   An issue I encountered when testing it with multiplayer was that if I lifted an object, close to a player, it would for some reason just fall to the ground, and I wouldn’t be able to move it at all until the other player walks away from the object.

3. What solutions have you tried so far?
   I’ve spent a few hours going through chatGPT, documentation, friends and allat to hopefully find a solution. I’ve tried changing the collision, alignPosition mode, maxForce, Responsiveness however to no help.

The ONE thing that actually had a slight effect, was making the object I want to move massless. However, I don’t want it to be massless, and it created a further issue where other players would not be able to see you move the object until you let go of it. I have no idea what caused this but I ended up trying to focus on fixing the issue without making it massless, however to no avail.

The code is a bit messy and as I’ve mainly been trying to get a hang of the mechanic before “optimizing” it to look well however I do hope I can get this solved without having to resolve to something completely else.

I’m gonna take a guess and say it’s got to do with network ownership. Do :SetNetworkOwner(Player) on whatever the client is trying to grab.
