Booty5 v1.8.5b out now – Cached rendering and Marmalade SDK Audio Support

Well the proof is in the eating and not the making. I’ve spent some time putting together a small game using Booty5 called Leapo that I will eventually distribute as an example of how to use Booty5. Whilst developing this game I have come across various issues or missing features, hence this update.

Booty5 game engine changes:

  • Added new Actor setPositionPhysics() and setRotationPhysics() to set associated physics body position and rotation directly
  • Added new utils class that contains utility functions
  • Fixed actor and scene sorting using new sorting method in Utils called sortLayers()
  • Added new property to TheApp called use_marm which should be set to true if deploying to mobile using the Marmalade SDK
  • Added new property to Sound constructor called reuse which can be used to force the sound effect to be reused (only useful for short sound effects at may not play if one is already playing)
  • Added new stop / pause methods to Sound class, only usable with reusable sounds
  • Sound class will now use the powerful Marmalade audio system instead of standard, if its available
  • Added new method TheApp.parseAndSetFocus(scene_name) which parses xoml JSON and sets the named scene as the current scene
  • TimelineManager.add() now returns the timeline that was added
  • Scene.addActor() now returns the added actor
  • Actor.addActor() now returns the added actor
  • TheApp.addScene() now returns the added scene
  • ParticleActor.addParticle() now returns the added particle
  • Main loop timer replaced with requestAnimationFrame for smoother rendering
  • TheApp now measures average frame rate via avg_fps property
  • TheApp has new property called adaptive_physics which will run physics update multiple times within a single frame if frame rate falls considerably outside target frame rate
  • Actors can now all be cached by setting cache property to true. When cached the actor will be rendered only once to an off screen canvas, subsequent rendering will be of the cached version. note that the Size of the actor as specified by its properties will determine the size of the cached canvas area. In the case of unfilled actors, the allocated size will be slightly larger to allow for stroke thickness. Note that shadows and composite operations are not cached

Booty5 game editor changes:

  • ExportName Scene property is now saved and restored correctly
  • Load scene property now cloned correctly
  • Target frame rate now exported
  • Fixed main.js for Marmalade SDK export, also now copy wb.js over from SDK into build folder
  • Marmalade native audio will be used in place of standard audio if available
  • Added new property to Sound resource called reuse
  • Added new project property called Adaptive Physics which can be used to run physics multiple times per game update
  • Unfilled rounded rects with corner radius now render properly
  • Actors can now be marked as cached which causes them to be rendered once to an off screen canvas
  • Added new measure button next to size property in properties panel, this will set the actors size to the extents of any attached geometry
  • Exported main.js will now wait until resources are loaded before starting TheApp

Whilst all of the above changes are a positive, one of the more important changes includes caching of actors for rendering. HTML5 is not particularly fast (especially on mobile) at rendering things like gradients and shapes. Actors can now be marked as cached which will force them to be rendered once to an off-screen surface, subsequent renders will render the cached version. When deployed via Marmalade Web I am seeing a good 30-60 fps frame rate for Leapo on an iPhone 5C.

Goji Editor v1.8.4b out now

The Goji editor has had a new update today, mainly to bring the features more in line with Booty5. Changes include:

  • Added Support for ALT Tab to switch between previous / last resource
  • Added image preview to Icon background property
  • You can now select most resources directly in the object properties panel
  • Added shape editor
  • Added shape shape bitmap tracer and mesh optimiser
  • Concave fixtures are now exported as multiple convex fixtures
  • Changed code editor font to fixed size
  • Fixed actor insert crash bug
  • Fixed script / image auto reload
  • Fixed main canvas scaling
  • Fixed various export options
  • Fixed geometry not updating correctly bug
  • Fixed auto shut down of editor when clicking close button on are you sure dialog
  • Fixed deployment with Marmalade free license
  • Main changes relate to usability / productivity, just making things a little easier to use. Also the addition of the shape editor makes it possible to create physics shapes and geometries within Goji, avoiding the need for an additional shape editor.

    Booty5 v1.3 the free open source HTML5 game engine now available

    More happy coding evenings and weekends for me means more juicy features for you. Well, that’s a bit of a fib, the latest version 1.3 is more of a tidy up and documentation phase. I’ve spent a few hours each evening this week putting together the Booty5 introduction and the Booty5 API reference and along the way I ended up tidying up the source code. By the way, did I mention that the minified version of Booty5 without Box2D functionality is only 50k!

    v1.3 changes:

    • Added more comments
    • Actor setters now only dirty transform if a change is made
    • Actor.findActorDeep() removed
    • Actor.findActor() has additional parameter that allows recursive searching
    • Actor.sendToBack() added
    • Actor.addFixture() now returns the created fixture
    • Actor.addJoint() now returns the created joint
    • Scenes now active property which can be used to pause processing
    • Scenes will now still be processed when not visible
    • Scene.findActorDeep() removed
    • Scene.findActor() has additional parameter that allows recursive searching
    • Scene.sendToBack() added

    I’m hoping to have full support for Booty5 in the up and coming next beta release of the Goji Editor, so watch this space.

    Goji Editor the game IDE update

    Just a quick heads up on the direction of the Goji Editor. With the news of a free Marmalade SDK license becoming available, I am going to rework Goji to integrate much more tightly with the Marmalade SDK. This will include features such as:

    • Integration into the Marmalade build and deployment system, enabling deployment to all Marmalade supported platforms
    • Test / debug using the more capable Marmalade simulator
    • Development using C++ as well as Lua and XOML
    • Deployment to device from the editor
    • In depth publishing options which enable you to set up all of the different Marmalade deployment options more easily
    • Marmalade code snippets / help / tutorials to aid development
    • Code samples / tutorials section
    • EDK builder to assist in the creation of Marmalade extensions

    Other game development systems such as Corona and Gideros will still be supported for now. If you strongly want to keep support for Corona / Gideros then let me know

    Shuffle Match – Made with the Goji Editor

    I’ve just released a new game for Android called Shuffle Match that is entirely created with the Goji game editor exported to AppEasy. Its currently available on Google Play and will be available on other stores sooonish, including Apple. I will be releasing the entire project for this game in the near future, so that others can learn from it.

    The game was inspired by my youngest daughter, who likes to play matching games.

    Heres a few details about the game:

    Put your memory through a fun workout that starts with an easy warm up and progresses to a gruelling challenge worthy of any memory master.

    • Endless challenge, go as far as your memory will take you
