How to add gravity and max distance to a raycast

[Skybloxtest123561]

Hello, I am wondering how I can add gravity and max distance to a raycast using the workspace:Raycast(). Thanks!

[wf_sh (wait)]

The max distance of the raycast is the magnitude (length) of the second direction vector. Gravity though is a bit more complicated, you would probably want to look into bézier curves.

Alright, I’ve done this but it’s not realistic and it’s not using physics. (For context I am trying to make a baseball that sinks and when you hit it it will go flying.) My code is below.

function lerp(p0,p1,t)
	return p0*(1-t) + p1 * t
end

function quad(p0,p1,p2, t)
	local l1 = lerp(p0, p1, t)
	local l2 = lerp(p1, p2, t)
	local quad = lerp(l1, l2, t)
	return quad
end

game.ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function(plr, mouseHit, hrPos)
	local start = hrPos + Vector3.new(0,0,3)
	local finish = mouseHit.Position
	local middle = (finish - start) + Vector3.new(0,30,0)
	local baseBall = game.ReplicatedStorage.BaseBall:Clone()
	baseBall.Parent = workspace
	for i = 1, 100 do
		local t = i/30
		local updated = quad(start,middle,finish,t)
		baseBall.Position = updated
		wait(0.01)
	end
	wait(2)
	baseBall:Destroy()
end)```

I have just found a tutorial and it showed me exactly what I was looking for, thanks for your help though as I may use that info in the near future!
