Before release Alpha 0.9.3.0 the engine and game used to be compiled into a single executable. This was neat at the time, but with native scripting mod support being added in that very release, we had to switch to a shared library layout.
Now there are 3 binaries that are produced, your game's code and the engine(stored under
Engine/ respectively) now get bundled into the
UntitledVulkanGameEngine dynamic/shared library. This library links to the 2 wrapper executables, the first one uses the name from the
uvproj.yaml file and the other uses the same name but appends
Modded to the end.
Modded executable is hardcoded to load the
ModLib mediator library that all the mods link to, the other one isn't
Since the new wrapper executables now exists, you can write code for them under the
WrapperSource directory where the files
Wrapper.hpp are defined. The 2 functions there are called inside the executables, in them, you call any functionality that you want to be executed before the whole engine launches, here are some examples:
- Verifying the integrity of the libraries
- Connecting to the game's servers
- Checking for an update of the game
And, because 2 executables are compiled, on compilation the
UVK_COMPILING_WITH_MODS macro is defined for the
Modded executable, this way you can check for what target you're developing certain features.
A note about the Wrapper functions
A very important thing to note here is that the wrapper functions shouldn't access any engine code(especially the
wbegin function) since the engine hasn't started at that moment(will lead to a crash or weird behaviour)
