变量占位符

JSON文件中的变量在运行时被替换成一个变量的值。下面是TPython中可以的的变量占位符:

"%"

使用最多的占位符,它可以被替换成各种不同的值,具体取决于它所在的控件。 例如SSpinBox中,会被替换为SpinBox的值,按照SSPinBox的类型,可以是float或者int;而在SColorPicker中会被替换成颜色的值。其他文本控件中,会被替换成对应的字符串。

  • SSpinBox.OnValueChanged
  • SSlider.OnValueChanged
  • SColorPicker.OnColorCommitted
  • SCheckBox.OnCheckStateChanged
  • SExpandableArea.OnAreaExpansionChanged
  • SBreadcrumbTrail.OnCrumbClick
  • SSearchBox.OnTextChanged
  • SEditableText.OnTextChanged
  • SEditableTextBox.OnTextChanged
  • SMultiLineEditableText.OnTextChanged
  • SMultiLineEditableTextBox.OnTextChanged
  • SSearchBox.OnTextCommitted
  • SEditableText.OnTextCommitted
  • SEditableTextBox.OnTextCommitted
  • SMultiLineEditableText.OnTextCommitted
  • SMultiLineEditableTextBox.OnTextCommitted

"%JsonPath"

在Chameleon的界面JSON文件中,我们在"InitPyCmd"中有一个固定写法。例如MinimalExample中的写法:

"InitPyCmd": "import Example; chameleon_example = Example.MinimalExample.MinimalExample(%JsonPath)"

其中的"%JsonPath"在运行时会被替换成当前JSON文件的路径。以便MinimalExample这个类可以获得当前JSON文件的路径。该路径是区分各个ChameleonData实例的唯一标识。

"%actors"

SDropTarget.OnDrop 用于获取用户拖拽的Actor,功能可被"%**kwargs"取代,具体可参考:Drag and Drop Area

"%assets"

SDropTarget.OnDrop 和"%actors"一样,用于获取用户拖拽的资源,功能可被"%**kwargs"取代,具体可参考:Drag and Drop Area

"%folders"

SDropTarget.OnDrop 用户获取用户的拖拽的文件夹,功能可被"%**kwargs"取代,具体可参考:Drag and Drop Area

"%assets_folders"

SDropTarget.OnDrop 用户获取用的拖拽的资源文件夹,功能可被"%**kwargs"取代, 具体:Drag and Drop Area

"%**kwargs"

SDropTarget.OnDrop 运行时会被一个字典值替代,其中key为类型,值为实际物体或者资源的值; 具体:Drag and Drop Area

"%Index"

"%Index" 用户在SListView和STreeView中获取用户点击的Item的索引,具体可参考:List View

SListView.OnSelectedChanged SListView.OnMouseButtonDoubleClick SListView.OnSelectedChanged SListView.OnMouseButtonDoubleClick STreeView.OnSelectedChanged STreeView.OnMouseButtonDoubleClick

"%Item"

和"%Index"一样,用于获取用户点击的Item,具体可参考:List View

SListView.OnSelectionChanged SListView.OnMouseButtonDoubleClick STreeView.OnSelectionChanged

"%uv"

"%uv" 用于获取用户在SImage中点击的UV坐标,具体可参考:Use Images and Image Brush

SImage.OnMouseEnter SImage.OnMouseMove

"%mouse_flags"

同样,"%mouse_flags",用于获取鼠标的按键状态,具体可参考:Use Images and Image Brush

SImage.OnMouseEnter SImage.OnMouseMove SImage.OnMouseLeave

"%WidgetPath"

"%WidgetPath" 用于获取用户点击的SButton的路径,具体可参考: Buttons

SButton.OnClick

"%SelectionType"

"%SelectionType" 用于获取SComboBox的值发生改变的原因。可能的值有:

  • "OnKeyPress"
  • "OnNavigation"
  • "OnMouseClick"
  • "Direct"

SComboBox.OnSelectionChanged

"%map_change_type"

Chameleon Tool中的"OnMapChangedCmd",用于在Map切换时执行Python命令。

用途:

  • 感知关卡切换,并同步更新界面
  • Chameleon工具在关卡切换时清理引用,避免内存泄露或者内存泄露检查触发的崩溃

具体可见OnCloseCallback

  • "LoadMap"
  • "SaveMap"
  • "NewMap"
  • "TearDownWorld"

"%world"

Chameleon Tool中的"OnMapChangedCmd"。和上面的"%map_change_type"一样,用于获取新的世界(关卡)信息。

Extra
在MenuItem中还有"%asset_paths", "%context", "%floatArgs", "%intArgs", "%paths", "%strArgs", "%tool_path"这些占位符,其作用已经完全可被其他工具取代,不再推荐使用。
