How do I change the text of a textbox to the value of a variable?
I'm attempting to change Workspace.Scorekeeper,SurfaceGui.Frame.Round1's text to the score value Score=0 to 90
But my attempts have failed.
How exactly do I change the text of a textbox to something else? Attempt:
1 | If Workspace.PartScoreboard.SurfaceGui.Frame.Pin1.Backgroundcolor3 = color3.new(1, 0, 1) |
2 | Workspace.Scorekeeper.SurfaceGui.frame.Round1.Text.new ((score)) |
3 | end |

Lua is case sensitive, so you need to be careful. if should always be lowercase. To access the Workspace, the following are acceptable:
1 | game.Workspace |
2 | game:GetService("Workspace") |
3 | workspace |
BackgroundColor3 should always have proper case as well:
As GoldenPhysics stated, Text is a writable property. That means you can set it using =. The only time you can't set properties is if they are read-only.
You should also make sure that your conditionals are formatted as such:
1 | if (_____) then |
2 | -- Code if ____ is true |
3 | else |
4 | -- Code if ____ is false |
5 | end |
To check if something is the same as something else you can use ==
1 | local num = 2 |
2 | if 2 == num then |
3 | print("num is 2") |
4 | else |
5 | print("num is not 2") |
6 | end |
Here's the finished product:
1 | if workspace.PartScoreboard.SurfaceGui.Frame.Pin1.BackgroundColor3 == Color3.new(1, 0, 1) then |
2 | workspace.Scorekeeper.SurfaceGui.frame.Round1.Text = score |
3 | end |
Text is a Property
Text is a property of a GuiObject, just like BackgroundColor3, Position, and Size.
Literal string
Therefore, to set it, just get the property of the gui guiObject.Text and set it equal to the string you want .
1 | guiObject.Text = "the score is 5" |
Non-string conversion to string
It is also possible to use non-strings if they will automatically convert to a string, such as numbers, or if manually set to a string using the tostring() method.
1 | guiObject.Text = 5 |
Using variables
Variables can be used to store a string or non-string as described.
1 | local score = 5 |
2 | guiObject.Text = score |
Concatenation and string manipulation
Additionally, string manipulation - frequently concatenation - can be used.
1 | local score = 5 |
2 | guiObject.Text = "The score is: " .. score |
Or, with another variable:
1 | local score = 5 |
2 | local scorePrefix = "The score is: " |
3 |
4 | guiObject.Text = scorePrefix .. score |
The Final Result
1 | local frame = workspace.PartScoreboard.SurfaceGui.Frame --the path of the frame storing the guis |
2 | local score = 5 --the score, updated in other code |
3 |
4 | if frame.Pin1.BackgroundColor3 == color3.new(1, 0, 1) then --the conditional, as given, debugged |
5 | frame.Round1.Text = score --the assignment of the text |
6 | end |
It is important to use conditional statements (ifs) correctly. All keywords are lowercase (if not If), double equals == is used to compare while singe equals= is used for assignment, and all ifs require then to close the conditional.
