Support / Objects in Tile Maps?

« on: January 23, 2014, 07:14:03 am »

I want to have a level-designer/artist work on creating my map(s) using Tiled, and I would like them to be able to position objects in the scene using Tiled's object layers.

Do you have any plan to extend 2D Toolkit to expose TMX object information?  I really only need to be able to access the XML data, but it would be cool if that was mapped to a dictionary for easy lookup instead of ugly XML parsing methods.

Something like this:

• Get a list of ObjectLayers from the tile map object
• ObjectLayers have a list of MapObjects.
• MapObjects have information about their type (rectangle, ellipse, etc.), and a dictionary/map of key/value pairs entered from Tiled.

Also, the ability to replace an object with a prefab (the way you allow with tiles) would be great.

I'd be willing to help out with this if you're interested in including it.

Support / Loading PNGs from byte array

« on: March 03, 2012, 02:08:46 am »

I have a project where I need to do the following:

• Load a ZIP file using the WWW class
• Unzip the PNG files contained in the ZIP into byte arrays (one per image)
• Create a 2D UI object that is based on that PNG image data

Ideally, I could keep this all in memory rather than saving the PNG out to a file first.  The code might look something like this:

  // Pseudo-code for Zip reading
  byte[] data = myZipFile.sizeInBytes(filenameToUnzip);
  bool result = myZipFile.read(filenameToUnzip, data);
  // Create an object to use with 2D Toolkit (not sure what name your class would be)
  Sprite s = Sprite.create(data);

If there was no other way, it would also be OK to create the image from a PNG file.  In that case, I would unzip the PNGs into byte arrays and save them to the local file system.

  Sprite s = Sprite.loadFromZip("myFile.zip");

Even more ideally, I could call a method like this and it would load an image directly from the ZIP file itself:

  String pathToTheFileToReadFrom = "Folder/SomeFilename.png";
  Sprite s = Sprite.createFromZip("myFile.zip", pathToTheFileToReadFrom);


Is this possible with 2DToolkit now?  In the future?

Thanks!
