    <p>I have a Sprite, which is a ball, and it is falling properly, acording with my FixedStepPhysicsWorld options. But I would like a vector follow this ball as it is falling. So I decided to override the onManagedUpdate sprite's method.</p> <p>After lots of tests, I just got 1 vector drawn, then I realized that the pSecondsElapsed, were not being incremented.</p> <p>Here is my code:</p> <pre><code>@Override public void onPopulateScene(Scene pScene, OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception { sPlayer= new Sprite(200,0, playerTextureRegion, this.mEngine.getVertexBufferObjectManager()){ @Override protected void onManagedUpdate(float pSecondsElapsed) { super.onManagedUpdate(pSecondsElapsed); Log.d("&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;,&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;"+pSecondsElapsed+",""); } </code></pre> <p>The output is the following:</p> <pre><code>11-07 21:14:32.242: D/&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;,&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;0.02 (23720): [MainActivity.java:359:onManagedUpdate()] 11-07 21:14:32.257: D/&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;,&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;0.02 (23720): [MainActivity.java:359:onManagedUpdate()] 11-07 21:14:32.281: D/&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;,&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;0.02 (23720): [MainActivity.java:359:onManagedUpdate()] </code></pre> <p>My Engine is like:</p> <pre><code> @Override public Engine onCreateEngine(final EngineOptions pEngineOptions) { return new FixedStepEngine(pEngineOptions, 50); } </code></pre> <p>QUESTION: 1 - Why pSecondsElapsed is not changing? 2 - I want to draw vectors for each position of this ball. Should I detach and atach a new Line each time this method(onManagedUpdate) is called?</p>

    1. COthat variable is the time since last tick so it should be constant. but onManagedUpdate is called per tick so your code should still work as needed.

    3. COYou should make something like -> int sec = 0; sec+=pSecondsElapsed; and the use this "sec" instead of pSecondsElapsed.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
