How would I make this Raycast gun shoot in the air?

Asked by

So I made this gun script. It works, but only when I point my mouse to a surface and shoot. I want it to shoot when it points to the sky also.

The script:

view source
01tool.Activated:Connect(function()
02    firing = true
03    while firing == true do
04        local ray = Ray.new(script.Parent.barrelpos1.Position, (mouse.Hit.p - script.Parent.barrelpos1.Position).Unit * 100)
05        local raypart, position = game.Workspace:FindPartOnRayWithIgnoreList(ray, {char}, false, true)
06 
07        local Dist = (mouse.Hit.p - script.Parent.barrelpos1.Position).magnitude
08 
09        local Lazer = Instance.new("Part")
10        Lazer.Parent = game.Workspace
11        Lazer.Anchored = true
12        Lazer.CanCollide = false
13        Lazer.Size = Vector3.new(0.1, 0.1, Dist)
14        Lazer.CFrame = CFrame.new(script.Parent.barrelpos1.Position,mouse.Hit.p + Vector3.new(math.random(1,3),math.random(1,3),math.random(1,3))) * CFrame.new(0, 0, -Dist/2)
15        debris:AddItem(Lazer, 0.1)
16        wait(0.3)
17    end
18end)

Any help would be appreciated.

Try replacing mouse.Hit.p in line 07 with position from line 05. Because when the mouse is pointing towards the sky, there is no mouse.Hit, but there may very well still be a position since the ray will always have an end, even if there is no target.

02    firing = true
03    while firing == true do
04        local ray = Ray.new(script.Parent.barrelpos1.Position, (mouse.Hit.p - script.Parent.barrelpos1.Position).Unit * 100)
05        local raypart, position = game.Workspace:FindPartOnRayWithIgnoreList(ray, {char}, false, true)
06 
07        local Dist = (position - script.Parent.barrelpos1.Position).magnitude

09        local Lazer = Instance.new("Part")
10        Lazer.Parent = game.Workspace
11        Lazer.Anchored = true
12        Lazer.CanCollide = false
13        Lazer.Size = Vector3.new(0.1, 0.1, Dist)
14        Lazer.CFrame = CFrame.new(script.Parent.barrelpos1.Position,mouse.Hit.p + Vector3.new(math.random(1,3),math.random(1,3),math.random(1,3))) * CFrame.new(0, 0, -Dist/2)
15        debris:AddItem(Lazer, 0.1)
16        wait(0.3)
17    end
18end)
