HUD Library [hudlib]

• Version: 0.1, beta
• License: MIT (see LICENSE)

HUDLib aims to create a very simple and easy to use API in front of a powerful and complex backend. Sure, there are other mods that introduce APIs to simplify HUD development, but they all focus on some type of statbar (used for things like health) and don't support other HUD elements. However, HUDLib will support all available HUD elements (including statbars and waypoints), wrapping them in an API built to lessen the amount of code you need to make your HUD not only look nice but also be functional.

Why HUDLib?

When stacked up against other HUD libraries, HUDLib excels in that it supports all HUD elements and has an intuitive API allowing you to do more with less code (see features for more information). However, how does it stack up compared to the default Minetest HUD API?

• HUDs are identified by a name chosen by the modder rather than by arbitrary IDs
• HUDLib supports hiding/showing HUDs without entirely removing them add having to redefine them manually
• HUDs can be registered that will be shown to all players
• HUDs can be removed from all players with one line of code
• All of the HUDs attached to a specific player can be retrieved, including specifics about each HUD (e.g. original definition table, visibility, etc...)
• Callbacks can be added to the HUD definition to be automatically called (e.g. on_step, on_hide, etc...) not unlike those supported within node definitions
• HUDs can be automatically hidden by defining hide_after in the HUD definition
• ...and more!

Features

• hudlib.after using a named queueing system to replace minetest.after
• HUDs referenced by a name chosen by the modder
• Hide/Show HUDs without having to redefine the HUD
• Show an HUD to all players
• Remove a specific HUD from all players
• Auto-hiding HUDs
• Callbacks in HUD definition
  • on_step
  • on_show
  • on_hide
• List all HUDs attached to a player
• Remove all HUDs attached to a player

Planned

• Statbar API
• Waypoint API
• Custom APIs for each element type
• Parent-Child Constraints (e.g. the child's position is made relative to the parent's)
• Auto-repositioning of HUDs to avoid overlap (?)
