Also produce this same ore between the height range of -height_max and -height_min.
Useful for having ore in sky realms without having to duplicate ore entries.
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.
Below are the specific uses for fields in each type; fields not listed for that type are ignored.
Note: Future revisions to the HUD API may be incompatible; the HUD API is still in the experimental stages.
- 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.
- text: The name of the texture that is displayed.
- 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.
- statbar
Displays a horizontal bar made up of half-images.
- text: The name of the texture that is used.
- number: The number of half-textures that are displayed.
If odd, will end with a vertically center-split texture.
- 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: Direction in which the inventory list 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.
