Are you referring to the walk and run animations inside a player?
If so, the walk animation is commonly used for players who are moving slowly, usually at a walking speed of 8 or less:
(The first animation is the RunAnim while the second is the WalkAnim when I’m walking slower)
If this is what you’re referring to, it’s already implemented if you put in the correct IDs, you just aren’t seeing it because your WalkSpeed is probably set to the default of 16, which is causing you only to see one of the two.
If this is not what you’re referring to please correct me and elaborate on your issue!
On PC you can use UserInputService to detect when the player presses or releases left shift, on mobile you can create a button (either TextButton or ImageButton depending on your preferences) then use TouchLongPress to detect when a mobile user clicks the button or releases it.
bro not like that dude there is a button if player touches it become running in which player purchased and if touch back then walk anim bought play loomian legacy in mobile u will understand
You can create a button to which players can click it to change their walkspeed and animation. You can detect if the player has gamepass which then allows them to see the button.
