How to make projectiles float on the ground without losing speed or getting too laggy on the client

  1. What do you want to achieve? I want when the projectile arrives at a ramp it goes up

  2. What is the issue? the way I did the projectile takes a long time to go up the ramp and I don’t know of any other way. here is a video of it:

as you can see, the projectile goes up very slowly compared to its initial speed, it doesn’t go down and it comes out very laggy on the client

  1. What solutions have you tried so far? I tried to use raycast to leave the projectile always above the ground but it takes a long time

here is the current code for the projectile to stay on the ground:

local ProjectileHeight = 5
local raycastParams =

		while true do

			local origin = Projectile.Ray.WorldPosition
			local raycastResult = workspace:Raycast(origin, Projectile.Ray.WorldCFrame.LookVector * (ProjectileHeight), raycastParams) -- Projectile.Ray is an Attachment
			if raycastResult then
				Projectile.Position = raycastResult.Position +, 5, 0)

here is the code that makes the projectile move:

local BodyVel ="BodyVelocity")
BodyVel.MaxForce =, math.huge, math.huge)
BodyVel.Velocity = ProjectilePos.WorldCFrame.LookVector * ProjectileSpeed -- ProjectilePos is the attachment from where the projectile will appear
BodyVel.Parent = Projectile
