so its like the core of the hud modification -my friend

What?

Basically a replacement of HDest's HUD, designed to be more modular for easier customisability.

On it's own, HUD Core is basically just the default HUD.
(though if you spot any oddities with the normal HUD stuff, please report it)

NOTE: Please don't copy the code of the modules, as they are poorly compiled through brute force scripting.

Usage

Just load it up with HDest, and it should run.
Again, you have to use addons that use HUD Core for anything to change.

Compiling

You should only do this if HUD Core doesn't work with the latest version or a specific version.

Anyhow, if you wish to compile HUD Core, just run compile.sh and pray it works. (make sure that you set the specific branch/commit for the hideousdestructor submodule)
For Windows users, you might want to grab Git Bash for this. (or anything that comes with Git and Bash)

Notice for Mac/BSD users

I wrote the compile script on Linux, which means that I used GNU sed.
Unfortunately, BSD sed doesn't have the substitution flag i, and therefore the script will fail.
The fix is simple: Use GNU sed :]
(no i'm not going to fix it, it's just going to make the script look even more worse than it already does)

Technical info

HUDElement

The generic class used by all HUD elements.

Variables:

• string Namespaces
  Each element has its own namespace. If there are elements with the same namespace, they'll overwrite each other. The namespace that takes precedence is the one that gets initialised last. (depends on your load order)

• int ZLayer
  Self-explanatory. If a element's Z Layer is higher than other elements, it'll be drawn on top of them.

Virtual functions:

• virtual void Init(HCStatusbar sb)
• virtual void Tick(HCStatusbar sb)
• virtual void DrawHUDStuff(HCStatusbar sb, int state, double ticFrac)

Utility functions:

• protected bool CheckAlwaysStuff(HCStatusbar sb, int state, double ticFrac)
  Returns true if the statusbar would be running DrawAlwaysStuff().

• protected bool CheckCommonStuff(HCStatusbar sb, int state, double ticFrac)
  Returns true if the statusbar would be running DrawCommonStuff().

• If you want to check for automap, just use the AutomapActive variable.

HUDItemOverrides

Used by elements that call an item's draw function. You most likely don't have to override this as all drawing is done by items. Instead, take a look at HCItemOverride.
Though, if you do end up overriding it, make sure to set the _OverrideType variable before calling Super.Init(). (see HCItemOverride for valid values)
Inherits from HUDElement.

HCItemOverride

Generic class used in HUDItemOverrides for overriding an item's draw function.

Variables:

• int OverrideType
  Determines the type of item that should be overridden.
  The following are valid values:

  HCOVERRIDETYPE_ITEM (for items, or anything that inherits from HDPickup)
  HCOVERRIDETYPE_WEAPON (for weapons)
  HCOVERRIDETYPE_OVERLAY (overrides an item's DisplayOverlay() function)

• int Priority
  Self-explanatory. If an override's priority is higher than other overrides, it'll be used first.

Functions:

• abstract bool CheckItem(Inventory item)
  Used to check if the override should override the given item's draw function.
  The following functions will only run if CheckItem() returns true.

• virtual void Tick(HCStatusbar sb)

• virtual void DrawHUDStuff(HCStatusbar sb, Inventory item, int hdFlags, int gzFlags)
