  He means this:

  global number X = 0

  global number Y = 0

  global number a = 45

  X = cos(time*300)*200

  Y = sin(time*300)*300

  Object.x = X*cos(a) - Y*sin(a) + center.x

  Object.y = Y*cos(a) + X*sin(a) + center.y

  I can be done with the canvas plugin. For example look at the capx here:

  http://www.scirra.com/forum/cut-or-slice-an-Object_topic56228_post351923.html#351923

  Event 2 under the "dragdrop" group checks if a visible pixel is clicked.

  Here is a technique for isometric sorting with any sized blocks:

  http://bannalia.blogspot.com/2008/02/filmation-math.html

  The concept is simple, take any two visually overlapping blocks and you can calculate which should be drawn first by comparing their positions and sizes in isometric coordinate space.

  The second part of it is a bit trickier, which involves sorting by that comparison. It's apparently a topological sorting problem but it can be thought of in a simpler way.

  1. Make a list for each block of the blocks that need to be drawn first.

  2. Keep track of what blocks have been drawn.

  3. Draw the blocks whose list contains only drawn blocks.

  4. repeat 2 and 3 until all blocks are drawn.

  EDIT:

  Here is a test:

  http://dl.dropbox.com/u/5426011/examples17/iso3.4.13.capx

  Sorting fails if any objects are overlapping in isometric space or if there is a loop of blocks that need to be drawn before each other.

  It runs fine here. My OS is WinXPsp3.

  Did it just recently stop responding?

  I suppose I have just gotten used to it but to get an event out of being a sub event I drag it above the event it's a sub event of. Then I can switch the order to what it was before with another drag.

  The cases in which this is used is limited and it is more time consuming for me to design, code, debug and provide support for a plugin. So I won't make a plugin for this.

  Edit: Read too fast... Standby while I test something out...

  It will probably be fixed if you incorporate z position. With z position the texture will look correct with perspective. It also has the added benefit of eliminating the need to manually do the perspective transform.

  To add files to your exe look at the project toolbar. There is a folder called "files" that you can right click on to add files. Disregard the "sound" and "music" folders they are not used. Then change your sound actions to "play from resource".

  It looks like the uv's are changing. Unless you want a sub-texture, u and v displace should be left at 0.

  Perhaps try updating your graphics card driver.

  The 9-patch object is a good replacement for the tiledBG in this situation.
