Hey everyone, i’m currently working on a grip and carry system and it is designed to allow players to interact with other players who are in a “knocked” state.
The knocked state is triggered when a player’s health drops to zero, at which point they are prevented from dying by setting their health to a minimum of 1. In this state, knocked players are immobilized and are eligible to be carried (“C”) or gripped (“B”) by other nearby players. This system involves two scripts: a ServerScript and a LocalScript.
The ServerScript handles setting a player’s knocked state, handling health restrictions, and listening for the B and C key presses to perform grip or carry actions. The LocalScript complements this by playing animations and sounds on the client side.
The issue here is that the B and C keys, which trigger the grip and carry actions, aren’t working as expected. Despite proximity checks and event setups. I dont know if this is an event handling problem or what exactly.
I’ll post both scripts down below for further clarity… Thanks everyone…

For one, you cannot use UserInputService or any client-based service on the server. The server doesn’t have any user input, it’s the server! Only clients can listen to user input directly. You have the right idea in mind, but your execution is slightly off.
Another thing is that you’re firing to the person doing the gripping or the carrying to play the animation on the victim on the client which won’t really work as well as you think it might because that animation might not replicate, the behavior will be pretty weird since you’re welding two network owners to each other, so they’ll be fighting over that network ownership and causing other unusual behavior.
I suggest finding a different solution that doesn’t use welds, maybe use RigidityEnabled with AlignPosition to mimic the behavior of a weld without the network ownership features.
Thank you so much, that worked exactly as i wanted it to, had to move all input detection (UserInputService) to the client script as you stated, and i’m still working through welding issues trying to get it right.
On a side note, i dont know if you accept friend requests on discord, i’d love to occasionally learn from someone as knowledgeable as you, this has helped me a lot!
