Monkey 2 App Methods

[APCParticipant]

Team,

On Monkey X 1 we use these App important methods such as

OnLoading, OnCreate, OnUpdate, OnRender OnSuspend, OnResume and more.

In Monkey 2 I see OnRender and OnUpdate I did not see OnSuspend and OnResume that are important to mobile apps.

Is there a guide in this forum where I can get the info? Does Monkey 2 follow the same structure of MX1 reganding this methods?

For instance I had to call my own OnUpdate from OnRender because it was not called automatically.

Below is the a portion of my code. You can down load it from here http://monkey2.monkey-x.com/forums/topic/monkey-2-sample-app-and-audio-issues/

In my (incomplete yet) framework I go away from Window class, user know nothing about window – it hidden inside of my Application class that also don’t override monkey’s App class.

Inside of Application we have needed callbacks.

One way is to use OnUpdate, On… () virtual methods ,  other way is to use fields-as-func and subscribe to them . I preffer the second way because you shouldn’t extends class to use these callbacks .

OnUpdate – I think it’s normally in monkey2 to call it from render.

OnSuspend and OnResume logic you can extract from OnWindowEvent – see the docs.

Thank you.

In case I am working on a game my game class should extend View and not Window. does that also apply for mobile devices? Or it depends on the type of app I am developing.

A lot of OnBlah stuff that was in mx1 is now implemented as ‘signals’ in AppInstance, eg: Activated and Deactivated (probably more coming). You can ‘hook’ these up to your own handler like this (inside, say, your window’s constructor):

App.Activated+=OnActivated    ‘Assumes there’s an OnActivated method/function somewhere!
App.Deactivated+=OnDeactivated    ‘Assumes there’s an OnDeactivated method/function somewhere!

For OnUpdate, it’s up to you how to update, easiest way is just to update inside OnRender but you can also create a timer, eg:

New Timer( 60,OnUpdate )

I thought about this one as well as well, at first I thought that it was missing due to some sort of API economy.
For example with “New” you replace the “OnLoad”, with “OnRender” you replace the “OnUpdate”.
