Hi, most of the code is really spaghetti and could be done differently and in a better way, it was mostly so I could mess around and learn. But anyways

For 1.20.2:

1. The FabricTransformer (or the ModernVanillaTransformer if not using Fabric) transformer tries to inject pretty early in order to load necessary libraries properly.

2. It then calls HookClient#init to load Mixins.

3. There NEEDs to be a mixin which injects as early as possible, to launch the client. For 1.20.2, I decided to inject here

For 1.8.9:

1. The LegacyVanillaTransformer attempts to launch using a launchwrapper (Needed to load LWJGL 3 libraries for NanoVG)

2. The LaunchWrapper is pretty much just a stripped down version of the Mojang launchwrapper, just modified to suit my needs. In the end, it too calls HookClient and loads mixins.

3. See MixinMinecraft
