ofxGlobalContext2

Helper to use the context with singletons

Description

If you use a class that has a specific function (update ...) as a public member via this helper, call that function by assigning that function to an arbitrary timing

Corresponding function

• setup(only when calling setup)
• update(timing changeable)
• beforeUpdate(fixed timing)
• afterUpdate(fixed timing)
• beforeDraw(fixed timing)
• afterDraw(fixed timing)

Example

use class

class Data{
  ...
  void setup(){
    hogehoge...
  }

void update(){
    hogehoge...
  }
  
  void afterUpdate(){
    hogehoge...
  }
  ...
};  

use main app

  void ofApp::setup(){
    ...
    context::setup<Data>(); //call Data::setup() 
    context::setup<Data>(ofEvents().draw, OF_EVENT_ORDER_AFTER_APP); //want to change the update timing
    //If you do not need to call setup and you do not need to change the timing of update, you do not have to write this
    ...
  }

use ather scene

  class Scene_A{
    Data& data{context::get<Data>()};
  };
