First of all, I apologize if I confuse anyone with my messy drawing or terrible explanation. Currently I am scripting a bow that shoots an arrow to the Player’s mouse position. Using Bézier Curves I made it so the arrow drops to the mouse position. Everything works perfectly, but now I would like to add a max distance the arrow can fire. I figured I would use magnitude to check the distance between the tool’s position and the mouse position and then check if this distance is greater than the max distance I have set. This also works, but now I need to get the new P2 vector.

If we have our max magnitude to 30 studs and we fire an arrow that is 70 studs away. Instead of doing the top vector and firing the arrow 70 studs away, it should calculate a new P2 and follow the bottom vector that has a magnitude of 30 studs. I can easily get P0 and we can get P1 when we get the new P2. But how would we get the new P2 from the current vectors we have?

```
function quadBezier(t, p0, p1, p2)
return (1 - t)^2 * p0 + 2 * (1 - t) * t * p1 + t^2 * p2
end
function getp1(p1, p2)
local a,b,c = p1.X+p2.X,p1.y+p2.y,p1.z+p2.z
return Vector3.new(a/2, (b/2) + 3, c/2)
end
fire.OnServerEvent:connect(function(plr, mousePos, toolPos)
local points = {}
local distance = (mousePos - toolPos).Magnitude
print(mousePos - toolPos)
local p0, p2, p1 = toolPos,nil,nil
if distance < maxDistance then
p2 = mousePos
p1 = getp1(p0,p2)
local a = Instance.new("Model", game.Workspace)
a.Name = "Path"
for t=0,1,0.01 do
local p = quadBezier(t, p0, p1, p2)
points[t] = p
end
for i,v in pairs(points) do
local b = Instance.new("Part")
b.Anchored = true
b.Size = Vector3.new(1,1,1)
b.Position = v
b.Transparency = 0
b.CanCollide = false
b.Parent = a
end
end
end)
```

This is the current script just in case you need a reference to it.

P.S Didn’t know how to title this post because it is very specific
