// 1st; by adding a new option to the array in MenuScreensCustom.cpp and passing attributes/CBs to it
|

// 2nd; by calling the functions listed at the bottom of this file.

// -- Option types
|
|
//
|
|
// Static/select: You allocate the variable, pass it to function and game sets it from user input among the strings given to function,
|
|
// optionally you can add post-change event via ChangeFunc(only called on enter if onlyApplyOnEnter set, or set immediately)
|
|
// You can store the option in an INI file if you pass the key(as a char array) to corresponding parameter.
|
|
//
|
|
// Dynamic: Passing variable to function is only needed if you want to store it, otherwise you should do
|
|
// all the operations with ButtonPressFunc, this includes allocating the variable.
|
|
// Left-side text is passed while creating and static, but ofc right-side text is dynamic -
|
|
// you should return it in DrawFunc, which is called on every draw.
