    v0.0.2-unstable Pre-release

    flipfloppy1 released this 2024-07-13 21:23:40 +09:30 | 13 commits to master since this release

    v0.0.2-unstable

    New Features

    New Lua Globals:

    VUI_mouse: a table for all mouse-related info, including:

    • VUI_mouse.onPress: true if the mouse has just been pressed.
    • VUI_mouse.onRelease: true if the mouse has just been released.
    • VUI_mouse.down: true if the mouse button is currently down.
    • VUI_mouse.x, VUI_mouse.y: the normalised mouse coordinates relative to the upper left corner.

    VUI_signal: set flags through Lua that can be toggled to call conditional code in your C++ program. Set a field of VUI_signal to true to turn on the signal of that name; e.g:

    VUI_signal.quit = true.

    Triggers:

    if (uiHandler.HasSignalled("quit"))
  // VUI_signal.quit is true
else
  // false or nil

    For more information on use, see the examples provided in the lua scripts of this build.

    UI Text and Font Properties:

    Font rendering now works, which means that the text field now specifies a string of UTF8-encoded (possibly subject to change) characters that will be drawn to the screen. Other font and text-related properties include:

    • uiElement.textPos: The position of the top-left corner of the element's text, in normalised coordinates starting from the top-left of the viewport.
    • uiElement.font: The filepath to the font file, relative to the current working directory. See freetype's supported font types for the list of compatible font formats, excluding fixed-size font formats.
    • uiElement.fontColor: An RGBA value that determines the font color of the text. Doesn't actually do anything yet, but it's there.
    • uiElement.textSize: Also currently does nothing, but it is there.

    Note: text is always drawn one layer higher than its element's main vertices.
