any ideas on how to make a character walk without using any keys?

SKIP SOB STORY i've been messing around with body velocity only to figure out that bodyvelocity is completely useless. it doesn't push my character and when it does, it pushes it really slowly. after 3 hours of trying i decided to give up and face the fact that bodyvelocty and other rocket body thingies are completely useless and should never be in the game at all.

is there anyway to make a player walk without having to hold w. i guess i should put some code in here

local worstToolEver = Instance.new("BodyVelocity",workspace.Part)
worstToolEver.P = 1000000
worstToolEver.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
worstToolEver.Velocity = Vector3.new(0,100,0)

please answer with a solution that is not related to bodyvelocity, bodyforce, etc those body tools suck
