Trouble loading t2dTileLayer

#1 Okay, so I solved that. I didn't realize that you had to load the tile layer into a tilemap before you could load a layer file into it. My problem now is that it's not receiving mouse events. Here's the code I have now:

%streetLayer = new t2dTileLayer() {
			class = "streetClass";
			UseMouseEvents = "1";
		};
		$mapManager::tileMap.addTileLayer(%streetLayer);
                %streetLayer.loadTileLayer("~/data/tilemaps/emptyLayer.lyr");

And the code for my mouse event handler looks like this:

function streetClass::onMouseDown(%this,%modifier,%worldPosition,%clicks) {
	echo("street clicked on.");
        ...
}

That never get's called, at least I don't see the echo. Again, any help would be appreciated. Thanks.

#2 I don't understand this fully myself Darius. I was trying to figure out the onCollision callback and why it wasn't working for my own class. The only work around I found was using t2dTileLayer::onCollision, which to me would seem to be problematic if you had multiple tile layers and you wanted to ascribe different behavior to them all.

I asked about the rationale for this in another thread (http://www.garagegames.com/community/forums/viewthread/86745) but got zero replies. Wish I could help more.

#3 @Darius - try applying the useMouseEvents after you load the layer.

%streetLayer = new t2dTileLayer() {
class = "streetClass";
UseMouseEvents = "1";
};

$mapManager::tileMap.addTileLayer(%streetLayer);
%streetLayer.loadTileLayer("~/data/tilemaps/emptyLayer.lyr"); 
%streetLayer.setUseMouseEvents(true);

I have add similar problems with static sprites.

@Aaron - I don't know if this will help but it is useful if you are going to be doing a lot of mouseEvents with different overlapping objects. www.garagegames.com/community/forums/viewthread/77324 Darius you might want to check it out too

#4 Thanks for the suggestions. What I ended up doing was changing the mouse events flag and the class name in the gui, then saving it to the tile layer I was trying to load.

It worked, but it still seems like a screwy way of getting around things.

#5 I'm having a similar problem (TGB 1.7.4 on Windows XP). If I try something just like this:

%streetLayer = new t2dTileLayer() {
	class = "streetClass";
	UseMouseEvents = "1";
	};
$mapManager::tileMap.addTileLayer(%streetLayer);
%streetLayer.loadTileLayer("~/data/tilemaps/emptyLayer.lyr");

Then it tells me $mapManager::tileMap isn't a tilemap. So then I try something like this:

$mapManager = new t2dTileMap();

%streetLayer = new t2dTileLayer() {
	class = "streetClass";
	UseMouseEvents = "1";
	};

$mapManager.addTileLayer(%streetLayer);
%streetLayer.loadTileLayer("~/data/tilemaps/emptyLayer.lyr");

And TGB crashes when it runs the $mapManager.addTileLayer(%streetLayer); line.

Where are you defining $mapManager and what is the purpose of doing $mapManager::tileMap ?

#6 $mapManager is just a namespace for a set of variables, if you look at the script style guide, it recommends declaring global variables with a namespace prefix specifying a class or module that the global variable is related to. I could just as easily have called the variable $tileMap instead of $mapManager::tileMap.

When you define a t2dTileMap() you need to give it a scenegraph, otherwise it will crash when you try to add a tile layer, I'm not sure why though. You could do something like this:

$mapManager = new t2dTileMap(){
		scenegraph = sceneWindow2D.getSceneGraph();
	};

That should take care of your crashing problem.

#7 Thank you Darius, both for explaining the crash problem and pointing me to that script style guide.
