MouseWheel records the wheel event for mouse, positive value means scrolling down while
negative value means scrolling up. It can be also used for touchpad.
Prompt name result gives the result user entered in the prompt window.
GlobalData
GlobalData is the user-facing global state.
It won't be reset if you change the scene.
It is mainly used for display and reading/writing some localstorage data. Runtime values like time, input state, scene name, and volume are read-only; use the getter functions below to read them.
userdata records the data that users set to saveextraHTML is used to render extra HTML tags. Be careful to use thiscanvasAttributes is used to attach attributes to the game canvascamera records the camera position and zoom levelinternalData stores opaque engine-owned data; use getters instead of editing itOpaque internal engine data.
Environment
Environment is provided to users almost all the time.
It stores GlobalData and CommonData (Similar to GlobalData but just for one scene), so you can get and modify them through the Env.
Remove common data from environment.
Useful when dealing with portable components by yourself.
Most of the time it will not be used since it has been built into prepared update functions.
Add the common data to a Environment without common data.
This type is for user to use when initializing the messenger. It is very useful when dealing with local storage.
Turn GlobalDataInit into GlobalData.
