A UDim2 is a Data Type that uses 2 coordinates to place objects in the GUI system.
Makeup
UDim2.new(xScale, xOffset, yScale, yOffset)
A UDim2 is simply two UDims mashed together, for two X values and two Y values. The first X and Y values are used for scale, and the second X and Y values are used for Offset.
Use
UDim2 values are used only in GUI system objects. This allows you to place objects on the player's screen exactly where you want them to go. Also, because the UDim2 scales according to it's parent's size, you can set up a GUI that will scale to a different screen size by using a ScreenGui or a Frame.
Here are a few code examples of objects placed using UDim2 locations. Remember that "zero" is the top left corner of a GUI object.
–-A 50×50 frame 5 pixels from the top, 10 pixels from the left mainFrame.Position = UDim2.new(0.0, 10, 0.0, 5)
mainFrame.Size = UDim2.new(0.0, 50, 0.0, 50)
–-A frame that is half the size of the main screen, in the center
mainFrame.Position = UDim2.new(0.25, 0, 0.25, 0)
mainFrame.Size = UDim2.new(0.5, 0, 0.5, 0)
-–A 50×50 frame in the top right corner
mainFrame.Position = UDim2.new(1.0, -50, 0.0, 0)
mainFrame.Size = UDim2.new(0, 50, 0, 50)
-–A frame that is 1/4 the size of the screen, in the bottom right corner
mainFrame.Position = UDim2.new(0.75, 0, 0.75, 0)
mainFrame.Size = UDim2.new(0.25, 0, 0.25, 0)
--Combinations of Scale and Offset are acceptable too: A GUI that takes up half the screen and 10 more UDim2s
mainFrame.Size = UDim2.new(0.5, 10, 0.5, 10)
Constructors
| Constructor | Description |
|---|---|
| UDim2.new(XScale, XOffset, YScale, YOffset) | Creates a new UDim2 |
Properties
All of these properties are read only. You can't set them by doing UDim.x = 5 and must instead create a new UDim with the properties you want.
| Property | Type | Description |
|---|---|---|
| UDim2.X | UDim | The x dimension scale and offset |
| UDim2.Y | UDim | The y dimension scale and offset |
Operators
| Operation | Description |
|---|---|
| UDim2 + UDim2 | returns UDim2 with each component added individually |
