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>()}; }; ~~~
