    <p>I'm making a game using <a href="http://github.com/danielrh/jiglibjs" rel="nofollow noreferrer">JigLib</a> and <a href="http://www.glge.org/" rel="nofollow noreferrer">GLGE</a>. The camera follows the player the way I want it to, but when the player is close to a wall, the camera moves to the other side of the wall, which is annoying when there is something that needs quick reflexes.</p> <p>I tried using picking to move the camera when it can't see the player, but it only moves until half of the wall is in front of it and half is behind it, making an annoying split screen effect where one half of the screen is blank.</p> <pre><code>camera.setLocY(Math.max(playerMesh.getLocY() - 10, 3)); camera.setRotY(playerHeading); camera.setLocX(playerMesh.getLocX() + Math.sin(playerHeading) * Math.max(camera.getLocY() - playerMesh.getLocY() + 5, 0)); camera.setLocZ(playerMesh.getLocZ() + Math.cos(playerHeading) * Math.max(camera.getLocY() - playerMesh.getLocY() + 5, 0)); camera.setRotX(Math.atan2(playerMesh.getLocY() - camera.getLocY(), Math.max(camera.getLocY() - playerMesh.getLocY() + 5, 0))); var playerVec = [playerMesh.getLocX(), playerMesh.getLocY(), playerMesh.getLocZ()], cameraVec = [camera.getLocX(), camera.getLocY(), camera.getLocZ()]; scene.removeChild(playerMesh); scene.removeChild(floor); do { var ray = scene.pick(canvas.width / 2, canvas.height / 2); if (ray.distance &amp;&amp; ray.distance &lt; GLGE.distanceVec3(playerVec, cameraVec)) { camera.setLocX(ray.coord[0]); camera.setLocY(ray.coord[1]); camera.setLocZ(ray.coord[2]); cameraVec = ray.coord; camera.setRotX(Math.atan2(playerMesh.getLocY() - camera.getLocY(), Math.max(camera.getLocY() - playerMesh.getLocY(), 0))); } } while (ray.distance &amp;&amp; ray.distance &lt; GLGE.distanceVec3(playerVec, cameraVec)); scene.addChild(playerMesh); scene.addChild(floor); </code></pre> <p>Is there a resource where I could find information about how to move the camera to avoid walls? Is my code wrong?</p>

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.
