Description
UDim stands for Universal Dimension, and uses 2 coordinates.
A UDim consists of a Scale and an Offset. These are used to figure out where exactly the UDim's position is.
Scale is a number between 0.0 and 1.0 that is a percentage of the parent object's size. For example, if the parent object is 50 pixels wide, a UDim scale of 0.5 would be 25 pixels wide. 0.5 makes the size cover 50% of it's parent, same as 0.38 is going to cover 38%, 0.85 is going to cover 85%, and so on.
Offset is a specified Integer. This is a non changing value that is factored into the UDim calculation.
The final result is a combination of Scale and Offset. Scale * Parent's Size + Offset.
Constructors
| Constructor | Description |
|---|---|
| UDim.new(Scale, Offset) | Creates a new UDim from components |
GuiObject.Size = UDim2.new(0, 100, 0, 100) (GuiObject.Size = UDim2.new(X.Scale, X.Offset, Y.Scale, Y.Offset))
Properties
All of these properties are Read Only (you can't just set them UDim.Scale = 5, it doesn't work) but you can create new UDim.new( 5, UDim.Offset ).
| Property | Type | Description |
|---|---|---|
| UDim.Scale | Number | The scale value |
| UDim.Offset | Number | The offset value |
Operators
| Operation | Description |
|---|---|
| UDim + UDim | returns UDim with each component added individually |
