How would i go about re-doing my dive script and making it more consistent?

Right so i made a dive script that relies on animation and roblox bodyposition physics, however this method seems unstable and in so many ways a bit to buggy. Is there any substitution i can use instead of BodyPosition?

Humanoid.JumpPower = 1
Humanoid.WalkSpeed = 0
Humanoid.PlatformStand = true
local Look = Character.HumanoidRootPart.CFrame.LookVector
local BodyMover = Instance.new("BodyForce", Character.HumanoidRootPart)
local BodyMover2 = Instance.new("BodyForce", Character.HumanoidRootPart)
LoadedAnimation:Play()
BodyMover.Force = Look * 1500
BodyMover2.Force = Vector3.new(0, .85, 0) * 3000
wait(.5)
BodyMover2.Force = Vector3.new(0, -.55, 0) * 3000
BodyMover.Force = Look * 500

This action only works after the player has double jumped, then it sets the humanoids state into a platformstand and does the animation and uses the bodymover/position, however i want it to be a consistent smooth arc instead of just hoping and praying that when you land that you don't glitch or get sent flying. Any suggestions not involving roblox's physics?

Sorry if this was difficult to understand if you want to see how the dive script works, you can test it here: https://www.roblox.com/games/2816838979/World-of-Platforming
