Humanoid is not being re-defined

Help and Feedback Scripting Support
,
1

I want to make a script where if you are below a certain health, you will become in a “downed” state and have blur and a ColorCorrectionEffect applied to you.

I want to be able for this script to run even after character has respawned, but once the character respawns, all the functions that require the humanoid break even though I’ve re-defined the new humanoid and character inside my respawn function, any reasons why?

Script Location - StarterCharacterScripts

This has been bugging me for the past 2 days, any help would be appreciated!

Please try putting this in the StarterCharacterScripts. I think that should solve it. :grinning_face_with_smiling_eyes:

I spent 7 hours trying to solve the first issue, and found out that the issue was StarterCharacterScripts as

plr.CharacterAdded:Connect(function(character)

doesn’t run if put in StarterCharacterScripts because everytime a character loads, it refreshes all the scripts inside, which means that the plr.CharacterAdded function doesn’t have any time to run as it’s being reloaded.

Okay, I can understand your confusion. When you make a connection, redefining the variable/instance does not redefine the connection. You will have to redefine the connection every time the character respawns.

Thank you so much for your help! This works completely and I understand it more! :slight_smile:

So the problem was that Humanoid connections were still linked to the old humanoid? And your new script refreshes them to make sure that they are listening to the new Humanoid?
