CitrusEngine goes Stage3D with Starling

Hey folks, happy new year! My previous post go back from 1st december, I’ve been really busy : adding Starling in the CitrusEngine, learning iOS and working on my 2nd year school project. And obviously some great holidays between christmas & the new year.

Today I’m very pleased to share with you the Citrus Engine working on Starling! For those who don’t know it, it’s a platformer game engine using Box2D Alchemy and Signal libraries. However, it’s not only made for platformer games, you can use it for every 2D contents even if it isn’t a game thanks to its great Box2D management. So before this update, it has supported : Box2D physics, Signals event, a Sound Manager, a Console for quick debugging & tools, Input management, lots of defined objects like Hero, Baddy, Platform, Coin, Sensor, Moving Platform…, parallax, a Loader manager, level editors thanks to its own (the Level Architect made with Air), or using Flash Pro, or Gleed2D. 2 views : the flash display list and blitting, and a layer management!

Thanks to this update, the CitrusEngine now support the great stage3d framework Starling and I’ve also added 3 new objects Cannon, Teleporter & Treadmill, a Level Manager and an abstract class to store the game’s data. This two last things are optional you may use it or not. In this blog post I will explain how I’ve adapted the CE for Starling, and my updates with some examples. For a quick getting start with the engine please refer on its website or to the tutorials on this blog.

But let’s stop chatting, it’s time to test the demo :

Box2D Sound Spectrum

This week is really challenging : my second year school project has started this week. It’s a team project with a graphic designer, a designer, a project manager and me as a developer. Our concept sounds very promising!

No matter, this short introduction explained that I’m really busy, so this experimentation is not perfect due to a lack of time…
Anyway, click here to see a sound spectrum made with Box2D and the Citrus Engine using BitmapData.

PhysicsEditor template for the Citrus Engine

Some months ago, I bought two softwares from code ‘n’ web : TexturePacker to create SpriteSheet and PhysicsEditor to create easily box2d object from png file.

Today, I’m happy to share my first extension / template for PhysicsEditor’s software : I’ve created a template to export physics object for the Citrus Engine.

This is a quick usage example
.
Click on the physical object and press tab. The console is now open. Then write : set Box2D visible false and you will see its picture. It matches really well to the physical object!

Create a ladder for the Citrus Engine

Hi, today a quick post about how to create a ladder for the Citrus Engine.
It is a preview version, Michael Kerr requested me for his flash game scripting class !

I’m working with Eric to add it into the original package !!

So here is the result : the ladder in action

Teleporter, treadmill and cannon

After my game school project (Kinessia), I’m still doing some experiments with the Citrus Engine.

On its latest update, there was some new objects :
– a powerful particle system.
– new objects : missile, reward and reward box.

In this tutorial, I wil explain how to create new specific object which extends a Citrus Engine object.
At the end, we will have : a teleporter, a treadmill and a cannon that fires missile !
An ugly example.

Kinessia, game school project

Hey,

I’m happy to share with you my game school project made at the french Gobelins school, in Annecy.
It is now online : http://kinessia.aymericlamboley.fr/.

I worked with a graphic designer, Tiffany Francony, which made an amazing job !

For the exam we had high honours and the best rating !!

It is made with the Citrus Engine. The original version used a smartphone as a controller for the game, and all the HUD was displayed on this. I used a Java server to make the synchronization.

This is a simple web version, I can’t pay a Java server. The concept is more raw than the original one, there was a video at the beginning to explain the story, and our approach was on the website. But, that was all in french, so I cut off.

All the source code is available on GitHub.

A short video :

I hope you will enjoy the prototype 🙂

Create a breakout game with the Citrus Engine

Today this is a new tutorial on the great Citrus Engine framework. Before starting my school project, I wanted to try using box2D inside the Citrus Engine, so I will show you how create a breakout game !

Click here to play the game, don’t forget to click in the swf to enable keyboard.

Box2D with the WorldConstructionKit

Before the weekend, I suggest to dig into the Box2D API for Flash with the great WorldConstructionKit.
Box2D is a physical engine wrote in C++ and translated into many languages such as Java, Objective-C, AS3, JavaScript…

For ActionScript3, there are 2 ports : Boris the brave’s port, and the WCK. You can find a performance comparison here made by Allan Bishop.
The WCK is the best thanks to the Alchemy port : it translates the C++ into something which can be understable by Flash. More information here.

The WCK provides a “a toolset / framework for rapidly developing physics based games / websites within the Flash IDE. WCK allows you to layout your 2d worlds / game levels entirely within Flash and have them hook into the physics simulation without writing any code.”
