createTileLayer is not working ( at least for me ).

Hi,
I created a level for my game. I am able to load the map, to call createVisual. That is working. But when I call createTileLayer it doesn’t.

Am I the only only having this problem ?

The “createTileLayer” function is only for when you require to load a single specific layer, for most situations you won’t need to use it.

You should be fine with just:

[code]

local map = lime.loadMap( “map.tmx” )
lime.createVisual( map )

In fact I have game levels with 4 layers. On layer 1 and 2 I have static items. On layer 3 I have moving items driven by the game engine and on layer 4 I have static items. The aim of the fourth layer is to hide the moving items on some portions of the screen. So how do I do to access the display group corresponding to the third layer ?

I also have another question. I was playing with the tutorial about properties and I don’t understand why I need to create a visual of the map to access the properties associated with the tiles.

Thanks.

To get the visual of a certain layer you can do this:

  
local layer = map:getTileLayer( "layerName" )  
local visual = layer:getVisual()

And as for properties, you don’t need to create the visual to get access to properties, but you do need to create it to use Property listeners. [import]uid: 5833 topic_id: 10074 reply_id: 36839[/import]

Ok. Thanks. I am going to have a look.

It is working except for the properties :
If I put that :

 local layer = map:getTileLayer ( "StaticItems" ) ;  
 local list = layer:getTilesWithProperty ( "Type" ) ;  
 if list == nil then  
 print ( "Number of items = 0" ) ;  
 else   
 print ( "Number of items = "..#list ) ;  
 end  
  
 -- Create the visual  
 local visual = Lime.createVisual ( map ) ;

The result will be 0.

If I put that :

 -- Create the visual  
 local visual = Lime.createVisual ( map ) ;  
  
 --   
 local layer = map:getTileLayer ( "StaticItems" ) ;  
 local list = layer:getTilesWithProperty ( "Type" ) ;  
 if list == nil then  
 print ( "Number of items = 0" ) ;  
 else   
 print ( "Number of items = "..#list ) ;  
 end

The result will be 3.

Ok thanks, I will look into that. Out of curiosity, is there any reason you need to have properties before creating the visual? [import]uid: 5833 topic_id: 10074 reply_id: 36943[/import]

I have two components : the GameEngine ( logic ) and the GraphicEngine ( graphics ). The GameEngine creates the GraphicEngine. I associate properties with the tiles ( such as Type=Obstacle ) so that I can build some kind of topography I will use with my PathFinding function.

OK cool, I will see if I can get the properties accessible before visual is created for the next version. [import]uid: 5833 topic_id: 10074 reply_id: 37141[/import]

Hi,
just to tell you I found a workaround :
_ I create the visual in my GameEngine but set the property isVisible to false.
_ Get all the properties to build the logic representation of the world.
_ Pass the map to my GraphicEngine.
_ Call getVisual function on the map and then set the isVisible property to true.

Et voila.

Thank you for keeping me up to speed, I hope to have the issue solved for the next version so you won’t need to use the workaround but good to know just in case :slight_smile: [import]uid: 5833 topic_id: 10074 reply_id: 38248[/import]
