Is there a way I can disable Player control for a few seconds and re-enable control back.?
If your looking to stop the player from moving around and jumping while the camera is going through a cut scene you could set the character's Humanoid's Walkspeed and JumpPower both to 0 right before it begins,
character.Humanoid.WalkSpeed=0 character.Humanoid.JumpPower=0
Then when it ends you can set it back to the original values. You could record what they were before you changed them and set it to that recorded state
local w,j=character.Humanoid.WalkSpeed,character.Humanoid.JumpPower character.Humanoid.WalkSpeed=0 character.Humanoid.JumpPower=0 --start here --stop here character.Humanoid.WalkSpeed=w character.Humanoid.JumpPower=j
