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

December 18, 2014

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

December 3, 2014

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 v1.8.4b the free HTML5 game maker out now, support for the Marmalade SDK added

    November 28, 2014

    I realise that two updates inside of a week is a bit much but I wanted to get this update out quickly because I have changed the way gradients are used by game objects substantially, I’ve also added project generation for the Marmalade SDK using Web Marmalade. Web Marmalade is a system that enables you to package your HTML5 games / apps into a native app for a variety of different mobile phones and tablets, allowing you to submit them to the app stores. Web Marmalade also provides access to native device specific features. To export a Marmalade compatible project simply go to the Project Settings, select the Marmalade tab and tick the “Export MKB” option then either run or test the project. This will generate a project in the marmalade sub folder inside your project folder. You can import this file into the Marmalade Hub and then deploy your HTML5 game as a native app to a device or run in the simulator to test.

    Changes for this release include:

    • Replaced gradient angle with gradient start / end vectors
    • Labels can now use gradients
    • New Marmalade properties section added to project properties which enables a Marmalade SDK compatible web application to be exported

    Changes to the editor include:

    • Added support for gradients to unfilled shapes
    • Removed gradient angle property and replaced with gradient start and gradient end points
    • Added support for text gradients
    • Moved gradient style creation out of Xoml class and into Gradient class

    Booty5 the free HTML5 game maker 1.8.3b is out now

    November 25, 2014

    Booty5 is a free HTML5 game maker, for more information visit the Booty web site

    Been very busy since the last update extending the features of Booty5 to bring more HTML5 specific features into the editor. The editor changes for this release include:

    • Added mouse wheel joint type to list of joint types
    • Added new property called ExportName to Scene, this changes the name of the scene, but not its exported file name
    • Added support for corner radius to rects enabling rounded rects
    • Added support for none filled polygons, arcs, rects and labels
    • Added support for stroke colour and thickness
    • Layers are now exported and used by engine
    • Added support for shadows to all actor types
    • Added support for composite operations
    • Added support for Scene OnKeyPress, OnKeyDown and OnKeyUp events
    • Added new gradient brush type and gradient editor
    • Actors can now render gradient brushes at any angle

    Engine changes:

    • Added support for wheel joint
    • Added panning property to Scene to determine when the scene is being touch panned
    • Box2D begin and end contact callbacks now call both objects that were affected
    • Added corner_radius property to rectActor to render rounded rects
    • Added support for stroke colour and thickness to rect, arc, polygon and label actors
    • Added support for scene and actor layer ordering. Set layer via _layer property and not layer variable to ensure that re-sorting takes place
    • Added new shadow properties all actor types (shadow, shadow_x, shadow_y, shadow_colour, shadow_blur)
    • Added support for composite operations to actors
    • Added support for Scene onKeyPress, onKeyDown and onKeyUp events
    • Added new Gradient class that handles gradient brushes
    • Rect, Arc and Polygon actors can now render gradient brushes at any angle, angle is specified by new grad_rotation property
    • Added new demos keys, mouse joint, bitmap animation, shapes and gradients

    The idea is with this last crop of changes is to bring in more HTML5 and SVG style specific features such as support for keys, gradient brushes, rounded rects, shadows amd so on. Here are a couple of screen shots showing some of the new features:

    .NET open sourced!!!!

    November 19, 2014

    Not many things in the software development field surprise me these days, in fact the only things that have seriously surprised me in recent years are a) how good the Marmalade SDK is and b) how HTML5 is not really my enemy. However Microsoft open sourcing .NET has hit me like a truck full of surprises. I’ve always been a fan of C# and .NET, which all of my tolls are built on, so this is lovely news.

    Booty5 HTML5 Game Maker v1.8.2 out now

    November 16, 2014

    Much hammering and tightening has been under way of late, Santa and his helpers have nothing on how many hours have been put into getting 1.8.2b ready for release! :)

    Ok, enough about Santa, version 1.8.2b of Booty5 the Game Maker for HTML5 developers is now available for download.

    Changes for this release include:

    • Added brush background preview to Actor properties panel
    • Added ability to select shapes, actors, images and brushes across all property panels
    • Added shape editor
    • Added shape bitmap tracer and polygon shape mesh optimiser
    • Concave fixtures are now exported as multiple convex fixtures
    • Fixed crash that occurs after dragging an image into scene, deleting it then clicking on its generated brush
    • Fixed issue when saving a project for the first time using the Save button
    • Fixed issue where changing actors geometry was not being updated properly

    The most notable change for this release is the addition of a shape editor which enables you to create / edit shapes that can be used for clipping, actor visual representation and physics fixtures.

    The shape editor also supports auto tracing of bitmaps to generate optimised meshes, which are exported as sets of convex fixtures for physics.

    Another new cool feature is the ability to select many components using a list of selections. For example, you no longer have to type the name of a fixture shape in directly, instead you can select it from a list.

    Here are a couple of new screen shots:
