Raycast to 3D Position

#1

I’m trying to raycast from mouse position to a valid 3d position the player can travers to, however most of the time the player goes in the air or just doesn’t do anything, any better approach?

local _r = rayResult(UserInputService:GetMouseLocation().X, UserInputService:GetMouseLocation().Y)

if _r then
	Player.Character:FindFirstChildOfClass("Humanoid").Jump = true
	Tool.RemoteEvent:FireServer(_r.Position)
end

local _thrustVelocity = Instance.new("BodyPosition")
_thrustVelocity.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
_thrustVelocity.P = 40000
_thrustVelocity.Position = Pos
_thrustVelocity.Parent = Character.HumanoidRootPart

What defines a valid position for the player to travel to? Is it an issue with the raycasting (print position to check) or an issue with the BodyPosition?

It is related to that it sometimes it’s in the air no matter what

It’s more so supposed to look like this https://www.youtube.com/watch?v=lO4mY05kuOQ 0:20 but with physics it’s a difficult approach

I tried to use @EgoMoose formula however it doesnt seem to translate well in accordance with the mouse position.

local t = 1;
local mouse = game.Players.LocalPlayer:GetMouse();
local hrp = game.Players.LocalPlayer.Character:WaitForChild("HumanoidRootPart");

mouse.Button1Down:Connect(function()
	local g = Vector3.new(0, -game.Workspace.Gravity, 0);
	local x0 = hrp.CFrame * Vector3.new(0, 2, -2)

	-- calculate the v0 needed to reach mouse.Hit.p
	local v0 = (mouse.Hit.p - x0 - 0.5*g*t*t)/t;

	-- have the ball travel that path
	local bv = Instance.new("BodyVelocity")
	bv.Velocity = v0
	bv.Parent = hrp
	
	local nt = 0;
	while (nt < t*2) do
		bv.Velocity = CFrame.new(0.5*g*nt*nt + v0*nt + x0).Position
		nt = nt + game:GetService("RunService").RenderStepped:Wait();
	end
	print("reached")
	bv:Destroy()
end)
