    <p>I'm trying to rotate the camera around an object by using the touchscreen. The rotation around Y axis works fine (The X axis is disabled). Rotation around the X axis is really weird. when the Object (its a rocket) gets higher <code>rocket.position().y++ &amp; scene.camera().position.y++</code>, the rotation around the x axis gets bigger and weird. If the rockets stops <code>rocket.position().y = 500; &amp; scene.camera().position.y = 500;</code>, I can't rotate around x axis, I zoom in or out the object instead. With both axis enabled its weird as hell.</p> <p>In <code>initScene</code> I set the camera to look at the center of the rocket. </p> <p>Here's my code:</p> <pre><code>initScene: scene.camera().position.z = 90; scene.camera().target = raketeOBJ.position(); onTouchEvent: public boolean onTouchEvent(MotionEvent me) { if (me.getAction() == MotionEvent.ACTION_DOWN) { xpos = me.getX(); ypos = me.getY(); return true; } if (me.getAction() == MotionEvent.ACTION_UP) { xpos = -1; ypos = -1; touchTurn = 0; touchTurnUp = 0; return true; } if (me.getAction() == MotionEvent.ACTION_MOVE) { float xd = me.getX() - xpos; float yd = me.getY() - ypos; xpos = me.getX(); ypos = me.getY(); touchTurn = xd / -200f; touchTurnUp = yd / -200f; return true; } try { Thread.sleep(15); } catch (Exception e) { } return super.onTouchEvent(me); } UpdateScene: if (touchTurn != 0) { scene.camera().position.rotateY(touchTurn); touchTurn = 0; } if (touchTurnUp != 0) { scene.camera().position.rotateX(touchTurnUp); touchTurnUp = 0; } </code></pre>

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.
