Shooting Spring Grappling Gun To Bring Part to Player

Help and Feedback Scripting Support
#1

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

  1. What do you want to achieve?
    I want the player to be stationary not able to move and the non anchored part to come to the player who shot the spring grappling gun

  2. What is the issue?
    player stays put but the unanchored, unwelded part does not move. The spring is attached to the base part and then the hook part

  3. What solutions have you tried so far?
    tried unanchoring the part I want to move, tried anchoring the HumanoidRootPart, anchoring the Handle of the tool grappling hook shooter, making the part I want to come to me weightless. tried using a hat instead of a part, but can’t get anything to come to the player. Tried anchoring the base also. Tried increasing the stiffness by 10x.

ty so much for taking the time to help, I know its something stupid that I’m forgetting :frowning:
