LiveSplit autosplitter for Nomad.
- Auto start on Play clicked.
- Auto split on core repair.
For auto split functionality, the target property is LevelSwitch.coreFixAmount. This is initialized to 0 at the start of a level and increases to 1 the moment the player finishes repairing the core, which is the moment when the split should be triggered. An instance of LevelSwitch is attached to a GameObject named LevelManager in each of the three level scenes. Sadly, this object is in a different position in the hierachy for each scene, so three seperate pointer paths were needed. To save on some code repetition and to avoid wasting resources reading nonsense values when the relevant scene for a given path is not loaded, the ASL constructs memory watchers for these paths in the init block, and switches the active watcher based on the current scene name. Here are the rough semantics of the path used:
SceneManager
0x48 | .ActiveScene
0xB8 | .FirstRootGameObject
0x8 | .Next (Repeated x times where, x is the index of LevelManager GO in the scene)
0x10 | .transform
0x30 | .gameObject
0x30 | .Components
0x18 | [1] : *LevelSwitch
0x28 | .cppInstance : LevelSwitch
0x7C | .coreFixAmount
Time starts on pressing the Play button on the main menu. This button click invokes a method which launches a couple of coroutines, and ultimately doesn't make any convenient state changes. So, rather than some value used by the game which indicates that a new game has been started, I opted to leverage the properties of the Button class itself to detect that the button has been clicked. The Button class has a property named OnClick, of type ButtonClickedEvent. This in turn has a property named m_InvokedArray, of type object[]. Before the button has ever been clicked, this value is null (0x00), but updates to a valid pointer the moment the button is clicked. So, I detect a click when this value changes from 0 to any other value. Once again, here are the path semantics:
SceneManager
0x48 | .ActiveScene
0xB0 | .LastRootGameObject
0x10 | .transform
0x30 | .gameObject (MainCanvas)
0x30 | .Components
0x48 | [4] : *MainMenuManager
0x28 | .cppInstance
0x30 | .controlPanel : *GameObject
0x10 | .cppInstance : GameObject
0x30 | .Components
0x8 | [0] : Transform
0x70 | .Children
0x30 | [6] : Transform (PlayButton)
0x30 | .gameObject
0x30 | .Components
0x38 | [3] : *Button
0x28 | .cppInstance : Button3
0xE8 | .OnClick : ButtonClickedEvent
0x28 | .m_InvokeArray : object[]
