Weld doesn't work as intended

[KemalSenpai (Senpai)]

I was working on npc execution system and encountered this problem;

when I try to weld player’s humanoidrootpart to npc humanoidrootpart even if I set the player hrp as part0 for some reason it gives the control to npc and teleports the player to npc hrp location instead heres the code

(I’ve tried setting networkowner to player, and made sure the mass of npc is not higher than players character)

here’s the code “Attacker” is the player and “Victim” is the Npc
does anyone know why is this happening?

you should use a weld constraint which does the same thing without teleporting anything

and teleport separately

@KemalSenpai

teleports the player to npc hrp location instead heres the code

Its the root priority, the part that doesnt move when welding is the root part.

Weird Behavior with weld in a grab ability

The character that moves depends on root priority. The engine will get confused if 2 root parts are welded. Try changing the root priority of the one being grabbed to a higher number.

Hey thanks for your answer I tried it now and encountered something like this

any ideas on this?

Nope no idea, theres too much going on in that gif.

Try isolating just the welding portion in another script without vfx and avoid overcomplicating things.

ah I found the code line that was leading to this bug

turning autorotate off breaks it for some reason I dont know why though anyway rootpriority helped so thanks
