(In this implementation, I center the image horizontally and vertically, but if all your frame textures have the same size, you can omit that step.)
The correct frame (texture) is then displayed by the “mFrameDisplay” object. Here, we find out which frame needs to be displayed at the current moment. This method is part of the “SPAnimatable”-protocol, and will be called by the juggler in every frame. The interesting part happens in “advanceTime”. The “addFrame”-method just adds the texture to our frame array, and it creates the frame display image if that hasn’t been done before. A user of the class will not see the methods that are declared here. If you haven’t seen this before: that’s the Objective C way of marking methods as private. Here is the header of our class: SimpleMovie : SPSprite & lt SPAnimatable & gt part right at the beginning is a private interface.
SIMPLEMOVIEX MOVIE
As soon as the movie clip is added to the juggler, it will execute the animation. As you can see, we also add the movie object to a juggler - just like you do with tweens. The atlas contains the frames for the animation, and all relevant frames are added to the movie object.
I think that should be quite self explanatory. Let’s first see how we will use the class: SPTextureAtlas * atlas = mMovie = initWithFps : 5 ] ] ] ] When the animation is running, the “SPImage” will change its texture at a specified interval. It will also contain all “SPTexture” instances that are part of the animation. The class will be a subclass of “SPSprite” and will contain one “SPImage” object. But as such a class is really easy to create in Sparrow, I think it might be interesting to see how you could create it yourself. The next Sparrow release will most probably contain a class called “SimpleMovie”, which makes it easy to display those animations. I recommend that you add all your frames to a texture atlas - or several texture atlases, if necessary. To display these animations in Sparrow, you need to export each frame of your movie as an image. If you want, you can still create your movie clips in Flash, or in any other animation tool you like. In Sparrow, you have to use textures to create animations. In Flash, you normally use the Flash authoring tool to create animations (like the walk cycle of your main character), and then display and manipulate these movie clips in the game. One thing that many Flash developers will miss in Sparrow is the MovieClip class. However, reading this post is worthwhile nevertheless, because you can use this technique for your custom classes, too._
SIMPLEMOVIEX PRO
QuickTime Pro is not required.Update:_ Since version 0.8, Sparrow contains a movie clip class, so you don’t need to create one yourself, as it is shown in this tutorial. QuickTime MPEG-2 Playback Component is required to take advantage of MPEG-2 capabilities.
SIMPLEMOVIEX MAC OS X
Simple Movie CutterSimpleMovieX requires Mac OS X v10.3 or higher.
SIMPLEMOVIEX FOR FREE
įor occasional users, an unlimited demo version of SimpleMovieX is available for free download.
SIMPLEMOVIEX TV
SimpleMovieX is a tool for a wide public: Discriminating TV viewers that clean their recordings of commercials, Users of a digital camera, mobile phone or camcorder that need to edit, compile, convert and share their personal footage, Video collectors compiling music concerts or Google Video shorts. Huge files beyond 4GB, for example 6 hours of TV recording, can be edited without truncating. SimpleMovieX also provides a search pane to quickly find a sequence and an adaptable timeline for accurate playhead positioning even in large duration movies. Powerful editing operations like splitting a movie into clips, a Batch Converter, an Audio Waveform tool to make sharp audio editing and synchronization, are among most appreciated features of version 3. This new version adds a redesigned timeline, now using in/out/playhead model and can create MPEG-4 file with chapter markers, to be enjoyed on your iPod or iPhone. The main advantage of native editing is speed and quality, since no re-encoding is required to save edited movies. With a feature set roughly similar to QuickTime Pro, SimpleMovieX extends editing capabilities to other popular video formats AVI, Google Video, MPEG-1, MPEG-2 and MPEG-4.
