I need help on how to make your gun to follow your cursor?

Asked by 9 years ago

I've been joining some games and I need help on how to make you gun follow your cursor move side to side and up and down. But, I just can't seem to figure it out I keep researching and trying to learn how to code that.

Example: http://www.roblox.com/Apocalypse-Night-place?id=93307312

This is what I'm talking about.

Hmm try this. This is a piece of code I modified. But it only works with one handed weapons. If you want two handed weapons, I would try asking someone else. As I do not know how to do two hands.

Essentially, to make your gun follow the cursor, you need to make the handle hook to the camera, basically. I don't know how to explain it in English, and I speak English. The script should be a local script, by the way.

function WaitForChild(parent,...)
    local debugPrint = false
    for _, i in ipairs({...}) do
        if type(i)=='boolean' then
            debugPrint = i
        else
            while not parent:FindFirstChild(i) do  
                wait(1/30) 
                if debugPrint then
                    print(script.Name..':'..parent.Name..' Waiting for '.. i)
                end
            end
            parent=parent[i]
        end
    end
    return parent
end

function ForEach(parent,func)

end

function MakeValue(class,name,value,parent)

end 

function TweenProperty(obj, propName, inita, enda, length,sentinel)

end


local Tool = script.Parent
local Handle = WaitForChild(Tool,'Handle')

local equipped = false
local rayparts = {}

local oldC0 =nil
local nweld


Tool.Equipped:connect(function(mouse)
    Spawn(function()
        local colorChoice = 1
        if not Tool.Parent:FindFirstChild('Torso') or not Tool.Parent.Torso:FindFirstChild('Right Shoulder') or not Tool.Parent:FindFirstChild('Humanoid') then return end
        nweld = Tool.Parent.Torso['Right Shoulder']
        oldC0 = nweld.C0
        nweld.CurrentAngle = 0
        nweld.DesiredAngle = 0
        nweld.MaxVelocity = 0
        equipped = true
        while equipped and Tool.Parent:FindFirstChild('Torso') do
            local tframe = Tool.Parent.Torso.CFrame
            tframe = tframe + tframe:vectorToWorldSpace(Vector3.new(1, 0.5, 0))
            local taim = mouse.Hit.p -( tframe.p )
            nweld.C0 = (CFrame.new(Vector3.new(),tframe:vectorToObjectSpace(taim))*CFrame.Angles(0,math.pi/2,0))+Vector3.new( 1, 0.5, 0 )


            wait()
        end
        nweld.C0 =oldC0

    end)
end)

Tool.Unequipped:connect(function(mouse)
    equipped= false
    if nweld then
        nweld.MaxVelocity =.15
        nweld.C0 =oldC0
    end

end)
