acs-libs

A collection of Zandronum ACS libraries. Mainly GDCC.

ACS_Common

A header for GDCC meant to simplify writing code without libGDCC and libc, and for code intended to be ported from ACC/BCC. It does the following:

• Enables ACS strings by default, and defines a str alias to them.
• Enables the fixed point type for literals by default.
• Includes ACS_Zandronum.h, as well as stdbool.h and stdfix.h to provide the remaining ACS types.
• Defines ACS_SHORT_NAMES so ACS functions are included without the ACS_ prefix.
• Adds a def_local macro to use inside functions, to allow using local arrays without requiring libGDCC.
• Adds a set of printing macros taking advantage of macro magic and _Generic (Can be used like: Print("This is a number: ", 10, (char)'.');).
• Adds the LanguageLookup, GetPrintName and IntToHex macros to cover the gaps not covered by the print functions.

Remember to rename both modprefix_sta ocurrences to fit your project.

safe-malloc

A replacement for libGDCC aimed at simplifying mod interop/compatiblity. Performs memory allocation always starting from near the very top of the address space. Other copies of safe-malloc can coexist without issue since they're all aligned, and regular ACS mods using the same global array are very unlikely to run into any conflicts.

actorlib

A library making use of GDCC's struct properties to provide an ActorT struct that can call many functions in a more seamless way. For example:

ActorT monster = {someMonsterTID};

monster.health = 200; // calls ACS_SetActorProperty(0, APROP_Health, 200)
if(monster.height < 32.0) // calls ACS_GetActorPropertyFixed(0, APROP_Height)
{
    monster.speed = 32.0;
    monster.scaleX = monster.scaleX - 0.1;
}

It also provides a global called self, in much the same vein as QuakeC. This allows referring to the script activator without any extra definitions:

self.giveInv("Shotgun", 1);
self.health = 150;
self.viewHeight = self.height - 2.0;
