Build System Flying Towards Camera?

Asked by

5 years ago

I have recently made a Building system but for some reason it flys towards the camera. I have spent hours trying to fix this error with no success.

https://gyazo.com/09df3bb688d3a81e47edbe75880a044e

Here is my code:

01local mouse = game.Players.LocalPlayer:GetMouse()
02local Model = workspace:WaitForChild('Window1')
03 
04local posX = mouse.Hit.X
05local posY = mouse.Hit.Y
06local posZ = mouse.Hit.Z
07 
08local function Snap()
09    posX = math.floor(mouse.Hit.X)
10    posY = mouse.Hit.Y
11    posZ = math.floor(mouse.Hit.Z)
12end
13 
14mouse.Move:Connect(function()
15    Snap()
16    Model:SetPrimaryPartCFrame(CFrame.new(posX, posY + 3.7, posZ))
17end)
18 
19local function Place()
20    local WindowCopy = game:GetService('ReplicatedStorage').Objects.Window1:Clone()
21    WindowCopy.Parent = workspace
22    WindowCopy:SetPrimaryPartCFrame(CFrame.new(posX, posY + 3.7, posZ))
23end
24 
25mouse.Button1Down:Connect(function()
26    Place()
27end)

The problem is that the ray from the mouse is hitting the object you're trying to build, thus moving it slightly closer to the camera each tick.

To bypass this you can use Mouse.TargetFilter, which determines what objects should be ignored when casting the ray.

Here's the syntax and context of the code:

`1`	`Mouse.TargetFilter` `=` `workspace.Baseplate` `-- now the mouse ray will ignore the baseplate object`

And here's your script but with the implementation:

01local mouse = game.Players.LocalPlayer:GetMouse()
02local Model = workspace:WaitForChild('Window1')
03 
04local posX = mouse.Hit.X
05local posY = mouse.Hit.Y
06local posZ = mouse.Hit.Z
07 
08local function Snap()
09    posX = math.floor(mouse.Hit.X)
10    posY = mouse.Hit.Y
11    posZ = math.floor(mouse.Hit.Z)
12end
13 
14mouse.Move:Connect(function()
15    Snap()
16    Model:SetPrimaryPartCFrame(CFrame.new(posX, posY + 3.7, posZ))
17end)
18 
19local function Place()
20    local WindowCopy = game:GetService('ReplicatedStorage').Objects.Window1:Clone()
21    WindowCopy.Parent = workspace
22    WindowCopy:SetPrimaryPartCFrame(CFrame.new(posX, posY + 3.7, posZ))
23    mouse.TargetFilter = WindowCopy -- Now the mouse's raycast will ignore the window
24end
25 
26mouse.Button1Down:Connect(function()
27    Place()
28end)
