How to use a Vector3Value?
For a projectile shot from a cannon I want it shot in a certain direction using a Vector3Value inserted under the model Cannon so that for each different instance of the cannon in my world, I don't have to jump into the code and set a new (x,y,z).
Instead I wish to use a Vector3Value named "Velocity" whose direct parent is the Model "Cannon"
1 | local storage = game.ServerStorage |
2 |
3 | while true do |
4 | local cBall = storage.cannonBall:Clone() |
5 | cBall.Parent = game.Workspace |
6 | cBall.CFrame = CFrame.new(game.Workspace.Cannon.Barrel.Position) |
7 | cBall.Velocity = Vector3.new(50,0,0) |
8 | wait(2) |
9 | end |
This is the current code with the Vector3.new value there as a filler. How would I declare the Vector3Value as a variable so that the XYZ value that can be set in Explorer is used for the XYZ where the (50,0,0) is in the code

Thank you for any help given!

Assuming I'm understanding your question correctly, this should be a pretty simple task. We can simply declare the Vector3Value a variable the same way we would with any object, keeping in mind we'll still need the Value property of it.
Here's a quick revision of your code:
01 | -- I always declare my services with GetService at the beginning of all my scripts, but that's just me. |
02 | local storage = game:GetService'ServerStorage' |
03 |
04 | -- Make sure the Vector value is there before proceeding |
05 | local velocity = script:WaitForChild'Velocity'.Value -- don't forget the Value property |
06 |
07 | while true do |
08 | local cBall = storage.cannonBall:Clone() |
09 | cBall.Parent = workspace -- I also prefer using the built-in workspace variable, just to neaten your code a bit. |
10 | cBall.CFrame = workspace.Cannon.Barrel.CFrame -- we could skip the process of creating a new CFrame and simply use the object's. |
11 | cBall.Velocity = velocity -- assigning the value |
12 | wait(2) |
13 | end |
Hope this helped, let me know if you have any questions.
