This page describes how you can setup your development environment for ACE3, allowing you to properly build ACE and utilize file patching.
1. Requirements
- Arma 3
- Arma 3 Tools (available on Steam)
- P-drive
- Run Arma 3 and Arma 3 Tools directly from steam once to install registry entries (and again after every update)
- Python 3.x
- Mikero Tools: DePbo, DeOgg, DeTex, Rapify, MakePbo, PboProject >=1.70
*.hpp
removed from PboProject's "Exclude From Pbo" list-F rebuild RequiredAddons
disabled
- Python, Mikero Tools and Git in PATH environment variable
- CBA mod (release or development version)
2. Why so complicated?
If you have contributed to AGM you might be used to an easier build process, where there was even an .exe you could use for building. ACE3, however, makes use of CBA macros to simplify things and give the developer access to a better debug process, which requires a stricter build environment. Additionally, Mikero's Tools are stricter and report more errors than AddonBuilder does. The structure of this development environment also allows for file patching, which is very useful for debugging.
Not offering .exes for the Python scripts we use allows us to make easy changes without the hassle of compiling self-extracting exes all the time.
3. Getting Source Code
To actually get the ACE3 source code on your machine, it is recommended that you use Git. Tutorials for this are all around the web, and it allows you to track your changes and easily update your local copy.
If you just want to create a quick and dirty build, you can also directly download the source code using the "Download ZIP" button on the front page of the GitHub repo.
4. Setup and Building
4.1 Initial Setup
Navigate to tools
folder in command line.
cd "[location of the ACE3 project]\tools"
Execute setup.py
to create symbolic links to P-drive and Arma 3 directory required for building.
Should the script fail, you can create the required links manually. First, create z
folders both in your Arma 3 directory and on your P-drive. Then run the following commands as admin, replacing the text in brackets with the appropriate paths:
mklink /J "[Arma 3 installation folder]\z\ace" "[location of the ACE3 project]"
mklink /J "P:\z\ace" "[location of the ACE3 project]"
Then, copy the cba
folder from the tools
folder to P:\x\cba
. Create the x
folder if needed. That folder contains the parts of the CBA source code that are required for the macros to work.
4.2 Creating a Test Build
To create a development build of ACE3 to test changes or to debug something, run the build.py
file in the tools
folder. This will populate the addons
folder with binarized PBOs. These PBOs still point to the source files in their respective folders however, which allows you to use file patching. This also means that you cannot distribute this build to others.
To start the game using this build, you can use the following modline:
-mod=@CBA_A3;z\ace
4.3 Creating a Release Build
To create a complete build of ACE3 that you can use without the source files you will need to:
- Ensure
.hpp
is NOT in pboProject's "Exclude From Pbo" list
When the requirements are met:
- Execute
make.py version increment_build <other-increment-args> force checkexternal release
in thetools
folder, replacing<other-increment-args>
with the part of version you want to increment (options described below)
This will populate the release
folder with binarized PBOs, compiled extensions, copied extras, bisigns and a bikey. Additionally, an archive file will also be created in the folder. The folder and archive handle like those of any other mod.
Different make.py
command line options include:
version
- update version number in all files and leave them in working directory (leaving this out will still update the version in all files present in therelease
folder, but they will be reverted to not disturb the working directory)increment_build
- increments build version numberincrement_patch
- increments patch version number (ignored withincrement_minor
orincrement_major
)increment_minor
- increments minor version number and resets patch version number to0
(ignored withincrement_major
)increment_major
- increments major version number and resets minor and patch version numbers to0
force
- force rebuild all PBOs, even those already present in therelease
directory (combined withcompile
it will also rebuild all extensions)checkexternal
- check external references (incompatible only with<component1> <component2>
andforce <component1> <component2>
)release
- create release packages/archives<component1> <component2>
- build only specified component(s) (incompatible withrelease
)force <component1> <component2>
- force rebuild specified component(s) (incompatible withrelease
)
7. File Patching
File Patching allows you to change the files in an addon while the game is running, requiring only a restart of the mission. This makes it great for debugging, as it cuts down the time required between tests. Note that this only works with PBOs created using MakePBO, which build.py
uses.
To run Arma 3 with file patching add the -filePatching
startup parameter (since Arma 3 v1.50, file patching is disabled by default).
7.1 Disabling CBA Function Caching
By default CBA caches a compiled version of functions to reduce mission load times. This interferes with file patching. There are three ways to disable function caching:
- Load
cba_cache_disable.pbo
(included in CBA's optional folder - simply move it toaddons
folder for the time being) - Add the following to your test missions description.ext:
class CfgSettings {
class CBA {
class Caching {
compile = 0;
xeh = 0;
functions = 0;
};
};
};
- To only disable caching for a single module, hence greatly improving mission restart time, add the following line to the
script_component.hpp
file of said module (prepared in each ACE3 component, simply uncomment):
#define DISABLE_COMPILE_CACHE
All functions in module with DISABLE_COMPILE_CACHE
line can be recompiled without mission restart with [] call ACE_PREP_RECOMPILE;
command. You can add a addAction/keybind/pfeh with this code and use it for fast recompiling.
7.2 Restrictions
Files must exist in the built PBOs for file patching to work. If you create a new file you must rebuild the PBO or Arma will not find it in your file paths.
Configs are not patched during run time, only at load time. You do not have to rebuild a PBO to make config changes, just restart Arma. You can get around this though if you are on the dev branch of Arma 3 and running the diagnostic exe. That includes diag_mergeConfigFile
which takes a full system path (as in diag_mergeConfigFile ["p:\z\ace\addons\my_module\config.cpp"]
) and allows you selectively reload config files.
If you need to add/remove files, then you'll need to run build.py
again without the game running, and restart. That is all that is required to add new files for further use in testing.
