Interface modding

在《钢铁雄心IV》中，接口是指玩家用来与游戏交互的用户界面。

概述

接口文件的组件可以分为两组：容器和元素。例如，containerWindowType 是一个容器，而 iconType 是一个元素。

接口文件使用 .gui 文件类型。 所有接口文件都可以在 /Hearts of Iron IV/interface/ 中找到。

当出现 internal 字样时，这个部分的源代码是只有P社可以修改的，即它所指的主题是不可修改的。

宏

可以在界面文件中使用宏，以便更轻松地调整位置。

例如，这将使一个名为 WINDOW_X_POS 的宏，其值为 10。

@WINDOW_X_POS = 10

可以在元素中这样引用它：

containerWindowType = {
    name = "my_container"
    position = { x = @WINDOW_X_POS y = -600 }

    # ...
}

容器

容器用于将元素组合在一起，并将它们与内部函数相关联。

除非通过脚本化 GUI，否则无法添加新容器。这是因为容器的 name 属性在内部链接到容器所需的任何数据。常见的例外是，您可以在 countrytechtreeview.gui 中为自定义技术文件夹添加新容器。

容器定义的顺序和嵌套会影响它们的显示方式。

containerWindowType

最常见的容器类型，用于保存任何一组元素。

通常使用以下属性：

• name - 容器的名称。
• background - 容器的背景。
• position - 容器的屏幕位置。
• size - 容器的边界框。接受百分数( 如 100%% )。
• moveable - 设置是否可以拖动容器。
• fullscreen -设置是否将容器全屏化。
• orientation - 设置 position 属性的方向原点。
• clipping - 设置容器是否将修剪其他元素（如在边界处剪切其元素）。

以下属性用于动画容器：

• show_position - 容器在显示模式下移动到的屏幕位置。
• hide_position - 容器在隐藏模式下移动到的屏幕位置。
• show_animation_type - The animation type used to show the container (always decelerated).用于显示容器的动画类型（始终减速）。
• hide_animation_type - The animation type used to hide the container (always accelerated).用于隐藏容器的动画类型（始终加速）。
• animation_time - 动画播放时间（始终为 300）。
• upsound - 当容器移动到显示位置时要播放的声音。
• downsound - 当容器移动到隐藏位置时要播放的声音。
• fade_time - 淡入淡出的时间。
• fade_type - 淡入的类型（始终为线性）。

以下属性很少或从不使用：

• dontRender - 不渲染
• horizontalBorder - 水平边界
• verticalBorder - 垂直边界

scrollbarType

滚动条类型用于定义滚动条由哪些元素组成。

使用以下属性：

• name - 滚动条名称。
• slider - 用作滚动条滑块的按钮元素。
• track - 用作滚动条跟踪器的按钮元素。
• leftbutton - 用作滚动条左增量按钮的按钮元素。
• rightbutton - 用作滚动条右增量按钮的按钮元素。
• position - 滚动条的屏幕位置。
• size - 滚动条的边界框。
• priority - 滚动条相对于其他元素的优先级。
• borderSize - 滚动条边框的边界框。
• maxValue - 滚动条能移动的最大值（用于控制增量）。
• minValue - 滚动条能移动的最小值（用于控制增量）。
• stepSize - 使用增量按钮的单次增量大小。
• startValue - 滚动条滑块的初始大小。
• horizontal - 设置滚动条是水平 （1） 还是垂直 （0）。

Elements

容器中使用了多种元素类型。所有元素都必须在容器内使用，它们不会在容器之外工作。

元素将继承它们所在的容器的方向，除非为自己指定了方向。

以下元素可以自由添加，并可用于脚本化 GUI。

• iconType - 用于静态图像。
• instantTextBoxType - 用于文本。
• buttonType - 用于按钮。

以下元素依赖于内部代码。您可以添加新元素，它们不会填充数据。

• smoothListboxType - 用于平滑滚动列表。
• listboxType - 用于滚动列表。
• checkboxType - 用于复选框。
• OverlappingElementsBoxType - 用于重叠元素。
• editBoxType - 用于可编辑的文本框。
• shieldtype - 用于显示国家/地区旗帜。

以下元素已过时：

• guiButtonType - 与 buttonType 相同。
• textBoxType -与 instantTextBoxType 相同。
• eu3dialogtype - 与 windowType 相同。
• shieldtype - 仅在 eu3dialogtype 中使用。 较新的文件中的标志使用不同的元素。

Position and Orientation

Understanding how the position coordinates work is important to understanding how to edit interfaces correctly.

The orientation attribute used by an element (or container) informs you where the anchor point for the element is. For example, UPPER_LEFT means the ( 0, 0 ) position is in the top left corner of the screen, whereas LOWER_RIGHT is the bottom right.

The position attribute then works from this origin position. Therefore if you want an element to be on the opposite side of the screen, you'd want to change the orientation first.

This is system is used because it allows the interface to adapt to different resolutions. Because all positions are tied to a specific origin that is dynamically calculated from the player's screen resolution, the placement of containers and elements are kept consistent.

So, if you want to ensure your interface edits are consistent, you must use the orientation attribute properly.

An mistake would be to edit the position solely, for example position = { x = 1800 y = 200 }. This would look fine for anybody with a screen width greater than 1800px (i.e. 1900 x 1200 upwards), but the element would be off screen for those with smaller screens.

Valid orientation values (can be upper or lowercase):

• CENTER
• UPPER_LEFT
• LOWER_LEFT
• UPPER_RIGHT
• LOWER_RIGHT
