This section will cover the main steps for implementing a new layer whose purpose is showing all targets of a selectable [[Tutorials|tutorial]] on a Canvas/MapStructure map. | This section will cover the main steps for implementing a new layer whose purpose is showing all targets of a selectable [[Tutorials|tutorial]] on a Canvas/MapStructure map. | ||
First of all, we need to find an aircraft that comes with a tutorial that contains targets: | |||
<code>cd $FG_ROOT/Aircraft/c172p/Tutorials && grep -nr targets</code> | |||
<pre> | |||
taxiing.xml:29: <targets> | |||
taxiing.xml:55: </targets> | |||

So, for testing/development purposes, we will be using the default FlightGear aircraft, i.e. the c172p, because it comes with well-maintained tutorials, and because its '''Taxiing''' tutorials contains a number of <code>targets</code>. | |||
