Introduction
In this training topic, you will learn how to construct an AnimationSequence class and introduce AnimationDelay class to create an animation sequence.
Steps:
- AnimationSequence Class
Prerequisites
You have prepared the Host PC with all the development software tools and Ensemble Graphics Toolkit source code as explained in:
You have installed and prepared the Eclipse IDE for C/C++ Developers as explained in:
You have performed the exercises on the topic:
AnimationSequence Class
In this section, you will modify the timer.cpp source code that you entered in the training topic Ensemble Graphics Toolkit: Animation Part 1 to construct an animation sequence.
In this training topic, you will use EgtProject and its settings you entered in the training topic: Ensemble Graphics Toolkit: Animation Part 1.
1
Modify the event.cpp source code by adding the following lines of code:
2
Save your program by selecting File > Save. You may also save with the command CTRL+S.
3
To build the project, hover over EgtProject, right-click, and select Build Project from the menu. Or you can click on the Build icon.
The Console window (bottom pane) will display the build progress.
4
Click on the Run button.
5
Observe the WVGA Display on the target:
The timer.cpp executable is running remotely on the target.
Observe the label “Ensemble Graphics Toolkit” at the top of the WVGA Display move (animate) along the animation sequence entered in the source code above.
AnimationSequence class
From ~/egt/docs/html/annotated.html, click on the AnimationSequence class. All the functions, attributes, and constructors associated with the class are documented here.
The AnimationSequence class allows users to add and manage a series of animation objects and run them as a single animation. It also allows users to add one sequence into another to create complex animations.
AnimationDelay class
From ~/egt/docs/html/annotated.html, click on the AnimationDelay class. All the functions, attributes, and constructors associated with the class are documented here.
The AnimationDelay class allows user to insert simple delays into an animation sequence.
6
To stop the program, press the Stop button (upper left hand, just below the menu bar).
Before you start another session, be sure to Stop the current session.
Summary
In this training topic, you learned how to construct an AnimationSequence class and use AnimationDelay class to create an animation sequence.
