| It is the last capability which makes **Tweakers** so powerful, since hooking into the game's [[ClassLoader]] allows almost unlimited control over the game's internal code. | It is the last capability which makes **Tweakers** so powerful, since hooking into the game's [[ClassLoader]] allows almost unlimited control over the game's internal code. | ||

| **Forge ModLoader (FML)** has a capability for a mod to elect to become a *"core mod"* which sounds very similar to the features just described for Tweakers above, and this is no coincidence. This is because **FML** is a **Tweak** itself and chooses to delegate its power to "core mods" which require it, any **Tweak** can do this and LiteLoader does so as well, although it doesn't make a distinction between "core mods" and "regular mods" and simply lets any mod supply [[transformers|Class Transformers]] if it wants to. | **Forge ModLoader (FML)** has a capability for a mod to elect to become a *"core mod"* which sounds very similar to the features just described for Tweakers above, and this is no coincidence.

| In a nutshell, a "core mod" accepts delegated power from a **Tweaker** without becoming a **Tweak** itself, this makes it dependent on the first **Tweaker** and not on the Tweak System directly. | In a nutshell, a "core mod" accepts delegated power from a **Tweaker** without becoming a **Tweak** itself, this makes it dependent on the first **Tweaker** and not on the Tweak System directly. | ||

| + | How do they work? | ||
| + | ================= | ||
| + | |||
| + | Whilst it is incredibly powerful, the Tweak System itself is actually incredibly simple. It leverages a library called [LaunchWrapper](https://github.com/Mojang/LegacyLauncher) originally written by [[people:cpw]] for Mojang in order to allow them to run old versions of Minecraft inside the new launcher. To use **Tweak**s, **LaunchWrapper** is simply added to the game environment and the game's **main class** is replaced with **LaunchWrapper's main class**. Tweak classes can then simply be specified on the command line using ''--tweakClass'' arguments. | ||
