I’m making a dash function for the character and I wanted to make a model when dashing (Old script was the local script or 2nd script) but of course the model wouldn’t appear for everyone else because originally it was a local script so I tried using a server script to replicate the model to every player but it did work but broke the dash function. The server script successfully replicated the model to every player but the player didn’t dash at all? The script looked perfectly fine to me and there were no errors or warns.

From a quick scan, I noticed your parameters for OnServerInvoke is missing the first property which is always the player who invoked the server.

Dash_Function.OnServerInvoke = function(Dash_Direction)

Should be

Dash_Function.OnServerInvoke = function(Player, Dash_Direction)

Since this parameter is none of “Front”, “Back”, “Right”, or “Left” then none of your conditions would be satisfied and therefore the BodyVelocity.Velocity would never be set, but it also wouldn’t error, which matches what you described.

Oh my god, how did I forget about the player parameter, I geniunely feel so embarassed lol
I didn’t have to put the player parameter on the bindable function so I forgot it
