Setting tiles by grid co-ords[Solved, kind of]

#1 Well, here's my method for tile placement, don't know if this is the best method, but this works for me in my current game. There might be a much better way to do this, but this is the way i figured out.

T2DTileType _targetTileType = _tileLayer.GetTileByGridCoords((int)_lastPosition.X, (int)_lastPosition.Y).TileType;
T2DTileObject _newTile = new T2DTileObject();
_newTile.TileType = _targetTileType;
_tileLayer.SetTileByGridCoords((int)vec.X, (int)vec.Y, _newTile );

So you can see, I basically get a tile type, create a brand new tile object, asign the object a new tile type, and set the tile by grid coords... seems to work.

-Will

#2 That's pretty much the exact same thing I'm doing except that as soon as I call SetTileByGridCoords I get that disposed Vertex Buffer crash.

#3 Perhaps there is something that is done when you assign the tile type, that doesn't get done when you clone it.. did you try it my way?

#4 Yeah. I used that way initially.

_finishTileVert = new aStarNode();
            _finishTileVert.TileType = SceneObject.TileTypes.Find(delegate(T2DTileType obj) {
                if(obj.MaterialRegionIndex == 4)
                    return true;
                return false;
            });
            _finishTileVert.TileTypeIndex = _finishTileVert.TileType.Index;
            _finishTileVert.TileTypeName = _finishTileVert.TileType.Name;

(I've run the debug and the delegate finds a tile type and it is the one I'm looking for)
And then setting the tile like so:

bool x = SceneObject.SetTileByGridCoords((int)tile.GridPosition.X, (int)tile.GridPosition.Y, _finishTileVert);

(aStarNode is an overload of T2DTileObject that I use for my pathfinding. It just adds 3 properties to the T2DTileObject. I've changed my T2DTileLayer as well to take aStarNode as inputs for the picktile, gettile and settile methods. I've also made the list of tiles in the T2DTileLayer a list of astarNodes. It hasn't given me any problems so far and I couldn't see how this would create this kind of problem with invalidated resources)

#5 Alright, I loaded up a brand new project and tried doing the same thing and it works, so it must be the changes I've made to the engine.

#6 Hm, now this is boggling my mind.

I've created a new project, I can set tiles. I even tried loading up my altered code with the aStarNode changes and it works fine (all of my changes. I did so by creating a Tortoise patch that I applied to the new project). I'm using Tortoise to go through all of the changes I've made to the source. In the mean time, does anyone know what might be happening?

Here's the stack trace if it helps anyone:

EDIT:

Well, it's definately not the source. I've copied it back from the working new project and still no dice.

I'm going to try to find when this is getting disposed.

EDIT:

Well, I've sorted out that it all works, except that you cannot seem to call a SetTileByGridCoords in a particle collision delegate. I'll fire Pino an e-mail about it.
