createMarker question

[Luft08 27]

The wiki gives an example of the use of createMarker:

_marker1 = createMarker ["Marker1", position player];

It also explains the parameters as: name, position and says that it returns a string. However, I don't understand what the string is. How can I use it? Is it some kind of id?

It will be "Marker1" the name given to the marker, as all markers are referenced via their name.

For instance getMarkerPos

Syntax:

getMarkerPos markerName

Parameters:

markerName: String

So it returns one of the parameters that I supply? I don't understand how that is helpful?

You can then use that string to further manipulate the associated marker, for instance to move it, change its appearance, or delete it.

Yes, but my point is that it is a string that I supplied so I could do that even if it didn't return anything. I already have the string.  Maybe I'm not understanding something?

 

Oh well, it is what it is...

You can use the returned string to check if the marker has been created successfully.

Marker creation can fail if the marker name is already used by a marker, the createMarker command returns an empty string in that case.

Now that makes sense. Thanks.
