Represents a two-dimensional value where each dimension is composed of a relative scale and an absolute offset.

udim 是对 uv 贴图和纹理工作流程的增强，它使 uv 贴图的生成和分配纹理变得更加简单。 从本质上讲，udim 只是一个自动 uv 偏移系统，它将图像分配到特定的 uv 平铺上，它允许您对相邻表面使用多个较低分辨率的纹…

The UDim2 data type represents the position and size of 2D GUI elements. Each dimension is composed of a relative scale (as per parent) and an absolute offset (as per unit), which is represented by UDim. UDim2 is constructed from number values or UDim values. Returns a UDim2 value with all components set to zero.

我们注意到udim的选项有2个可选，一个是新版本适用的方式，也就是可以跨象限进行绘制，另外一个方式是旧版的udim。 上面一项为新版，下面一项为旧版。

2022年3月14日 · A UDim2 is a combination of two UDims, one for X and one for Y. It’s used for setting the size and position of UI elements. https://developer.roblox.com/en-us/api-reference/datatype/UDim2 175. Thank you for the explanation i have a clearer understanding now. Thanks for your help.

2024年8月11日 · UDIM（U DIMension ）基于一个切片系统，其中每个分块在整体 UDIM 纹理阵列中是不同的纹理。 基本上，每个分块都由其自己的 UV 空间（0-1、1-2、2-3）组成，并将各自的图像分配给该分块。

UDim2 is a data type used in OVERDARE Studio to define the size and position of UI elements. This value is calculated based on scale (fraction) and offset (pixel size). UDim2 is composed of two axes (X and Y) and is commonly used to set the size and position of UI elements in a flexible manner. UDim Specifies the value for the X-axis.

UDIM（U-Dimension）是一种用于纹理贴图的技术，可以在多个纹理空间中存放不同区域的纹理，从而实现更高的细节和更好的纹理管理。 优点包括： 高分辨率支持：

The most common usages for `Datatype.UDim2` are setting the `Class.GuiObject.Size|Size` and `Class.GuiObject.Position|Position` of `Class.GuiObject|GuiObjects`. ```lua local guiObject = script.Parent guiObject.Size = UDim2.new (0, 300, 1, 0) -- 300 pixels wide; full height of parent guiObject.Position = UDim2.new (0, 50, 0, 0) -- 50 pixel...

2020年11月8日 · UDim2 is a type of variable that is consisted of 2 UDim components. UDim2.new (xScale, xOffset, ySce, yOffset) The origin point of the screen, aka (0, 0, 0, 0) is at the top left corner of the screen.
