HUD

HUD element types

The position field is used for all element types.

To account for differing resolutions, the position coordinates are the percentage of the screen, ranging in value from 0 to 1.

The name field is not yet used, but should contain a description of what the HUD element represents.

The direction field is the direction in which something is drawn. 0 draws from left to right, 1 draws from right to left, 2 draws from top to bottom, and 3 draws from bottom to top.

The alignment field specifies how the item will be aligned. It is a table where x and y range from -1 to 1, with 0 being central. -1 is moved to the left/up, and 1 is to the right/down. Fractional values can be used.

The offset field specifies a pixel offset from the position. Contrary to position, the offset is not scaled to screen size. This allows for some precisely positioned items in the HUD.

Note: offset will adapt to screen DPI as well as user defined scaling factor!

The z_index field specifies the order of HUD elements from back to front. Lower z-index elements are displayed behind higher z-index elements. Elements with same z-index are displayed in an arbitrary order. Default 0. Supports negative values. By convention, the following values are recommended:

  • -400: Graphical effects, such as vignette
  • -300: Name tags, waypoints
  • -200: Wieldhand
  • -100: Things that block the player's view, e.g. masks
  • 0: Default. For standard in-game HUD elements like crosshair, hotbar, minimap, builtin statbars, etc.
  • 100: Temporary text messages or notification icons
  • 1000: Full-screen effects such as full-black screen or credits. This includes effects that cover the entire screen
  • Other: If your HUD element doesn't fit into any category, pick a number between the suggested values

Below are the specific uses for fields in each type; fields not listed for that type are ignored.

image

Displays an image on the HUD.

  • scale: The scale of the image, with 1 being the original texture size. Only the X coordinate scale is used (positive values). Negative values represent that percentage of the screen it should take; e.g. x=-100 means 100% (width).
  • text: The name of the texture that is displayed.
  • alignment: The alignment of the image.
  • offset: offset in pixels from position.

text

Displays text on the HUD.

  • scale: Defines the bounding rectangle of the text. A value such as {x=100, y=100} should work.
  • text: The text to be displayed in the HUD element.
  • number: An integer containing the RGB value of the color used to draw the text. Specify 0xFFFFFF for white text, 0xFF0000 for red, and so on.
  • alignment: The alignment of the text.
  • offset: offset in pixels from position.
  • size: size of the text. The player-set font size is multiplied by size.x (y value isn't used).

statbar

Displays a horizontal bar made up of half-images with an optional background.

  • text: The name of the texture to use.
  • text2: Optional texture name to enable a background / "off state" texture (useful to visualize the maximal value). Both textures must have the same size.
  • number: The number of half-textures that are displayed. If odd, will end with a vertically center-split texture.
  • item: Same as number but for the "off state" texture
  • direction: To which direction the images will extend to
  • offset: offset in pixels from position.
  • size: If used, will force full-image size to this value (override texture pack image size)

inventory

  • text: The name of the inventory list to be displayed.
  • number: Number of items in the inventory to be displayed.
  • item: Position of item that is selected.
  • direction
  • offset: offset in pixels from position.

waypoint

Displays distance to selected world position.

  • name: The name of the waypoint.
  • text: Distance suffix. Can be blank.
  • precision: Waypoint precision, integer >= 0. Defaults to 10. If set to 0, distance is not shown. Shown value is floor(distance*precision)/precision. When the precision is an integer multiple of 10, there will be log_10(precision) digits after the decimal point. precision = 1000, for example, will show 3 decimal places (eg: 0.999). precision = 2 will show multiples of 0.5; precision = 5 will show multiples of 0.2 and so on: precision = n will show multiples of 1/n
  • number: An integer containing the RGB value of the color used to draw the text.
  • world_pos: World position of the waypoint.
  • offset: offset in pixels from position.
  • alignment: The alignment of the waypoint.

image_waypoint

Same as image, but does not accept a position; the position is instead determined by world_pos, the world position of the waypoint.

  • scale: The scale of the image, with 1 being the original texture size. Only the X coordinate scale is used (positive values). Negative values represent that percentage of the screen it should take; e.g. x=-100 means 100% (width).
  • text: The name of the texture that is displayed.
  • alignment: The alignment of the image.
  • world_pos: World position of the waypoint.
  • offset: offset in pixels from position.

compass

Displays an image oriented or translated according to current heading direction.

  • size: The size of this element. Negative values represent percentage of the screen; e.g. x=-100 means 100% (width).
  • scale: Scale of the translated image (used only for dir = 2 or dir = 3).
  • text: The name of the texture to use.
  • alignment: The alignment of the image.
  • offset: Offset in pixels from position.
  • dir: How the image is rotated/translated:
  • 0 - Rotate as heading direction
  • 1 - Rotate in reverse direction
  • 2 - Translate as landscape direction
  • 3 - Translate in reverse direction

If translation is chosen, texture is repeated horizontally to fill the whole element.

minimap

Displays a minimap on the HUD.

  • size: Size of the minimap to display. Minimap should be a square to avoid distortion.
  • alignment: The alignment of the minimap.
  • offset: offset in pixels from position.
