Error deriving RTSBuildingMarker from StaticShape

Hi,

I've added a "build_point" helper node to one of our building .dts files, and I need to be able to call something like this:

object->getShape()->findNode("build_point");

I can do that with an actual RTSUnit object because it inherits from ShapeBase. However, the "build_point" node needs to be accessible *before* the actual building is placed/created (so I can tell the builder where to go to build the thing). At that point all I have is the RTSBuildingMarker, but that class inherits from TSStatic and doesn't have any "findNode" capabilities (as far as I can tell). So to get the functionality I needed, I tried to derive RTSBuildingMarker from StaticShape (which inherits from ShapeBase). But when I do that I get an error during object creation because the datablock field is NULL.

I'm just setting up the datablock like this (in client/scripts/buildings.cs):

datablock StaticShapeData(csBarracksBlock)
{
	shapeFile = "~/data/shapes/buildings/barracks/barracks.dts";
};

and then in the same file (in the startPlaceBuilding function) I create the object like this:

$NewBuilding = new RTSBuildingMarker()
{
	dataBlock = csBarracksBlock;
};

But when I try to run it I get this error: "Object 'csBarracksBlock' is not a member of the 'GameBaseData' data block class". I'm obviously doing something stupid but I can't see it. The only thing I can think of is that even though the datablock is defined in the same script as the "new RTSBuildingMarker" call, the script engine somehow doesn't really "know" about the datablock. Is that possible?

Is there an easier solution to all of this? I'm trying to keep the building marker class purely client-side and use as lightweight an object as possible. I just need to be able to get to that "build_point" node.

Thanks!
