Simple question. How would you disable jumping for the standard ROBLOX character? I understand that a while ago there was a method where you could use this:
while true do
plr.Character.Humanoid.Jump = false
wait()
end
To stop characters from jumping. However, this doesn't work any more.

Did you make sure to actually give plr the property of all players?
I was using that as an example.
