  Do sprites display correctly? Older ati cards have crummy drivers for opengl. I have an ati card on my laptop that is about 4 years old and for me re-sized sprites become transparent. The latest drivers did not fix it but for me tiledbackground objects display correctly. You can try to tweak the opengl display settings for your card as that sometimes can affect it. Another thing you can try is http://titaniumgl.tk/, which wraps opengl to directx.

  I found this site which has a fairly simple approch to doing weighted random.

  http://eli.thegreenplace.net/2010/01/22/weighted-random-generation-in-python/

  and implemented in c2:

  It can be made into a function fairly easily by using the "function plugin".

  You could use the tiledbackground object.

  DirectX plugin? You mean the runtime?

  The math isn't too complex:

  If you want it to just rotate relative to the screen remove the "set y" actions.

  Sprite.VertexX(1, 1) returns the displacement of the point from it's normal grid position, so if the point is unmoved it will be zero. If the point is moved then it returns the displacement relative to the size of the sprite. So if the sprite is 128x128 and you set the relative displacement of (1,1) to -128,0 then then Sprite.VertexX(1, 1) would return -1.

  To calculate the absolute position of any vertex at (column, row) use the following:

  X:

  ((Sprite.VertexX(column, row)+column/Sprite.MeshCols)*Sprite.Width+Sprite.Left

  Y:

  (Sprite.VertexY(column, row)+row/Sprite.MeshRows)*Sprite.Height+Sprite.Top)

  http://dl.dropbox.com/u/5426011/examples%208/absoluteVertex.cap

  Note:

  the above expressions do not work if the sprite is rotated.

  Age 27 (1/5th of my lifespan)

  Programming has been a lifelong interest.

  Maxis' "Klik n Play" was the first game creation program I had the pleasure of using and by logical progression I came to use Construct.

  If you're including the file and you're still getting the error then the second part of my answer probably applies.

  Windows explorer says that the python26.dll in construct's folder is version 2.6.2150.1013. Put that dll in the same folder as your exported exe and it should work.

  Edit: It isn't necessary to pm me with a duplicate of what you posted here.

  If you're still having issues you can find solutions yourself by doing small changes over an working install of CC. That way you can isolate what changes introduce the problems and go from there.

  Textures would be useful but I have to work out a clean way to reference them in expressions.

  Animmaniac

  You can do what you describe with effects.

  For example use the "Destination out" effect to subtract alpha:

  That error means StringIO.pyc can't be found/loaded. When exporting, python files are pulled from the .\data\python folder and put inside the exe. If the file can't be found then it can't be included. Another idea is .pyc files are compiled python scripts which only work for one version of python, so if the versions are different the pyc file can't be used. If that's the case then use the python26.dll that's in construct's install folder, that's the dll that's used in previewing.

  I added polygon filling to the first example and implemented a pressure based softbody from the paper here:

  https://www.dropbox.com/s/sshkr7gt8c646 ... .capx?dl=0

  It's a bit slower.

  I found a paper explaining a way to improve the simulation by using a pressure force instead of a spring force to a center. It looks like it will help with the edges getting tangled.

  Here's an way of doing one soft body.

  I did it with the physics behavior and implementing springs from a center to the edge points, and springs from point to point around the body.

  https://www.dropbox.com/s/984j5w3fh7y9v ... .capx?dl=0

  For graphics you could hide the center and edge points and use the canvas plugin to draw a filled polygon through the edge points.

  Well looking at the Facebook javascript sdk, in particular here it appears that everything on Facebook is potentially accessible.

  Per pixel collision detection is a must for such a game, but since C2 doesn't have per-pixel collisions you'll have to implement it manually.

  Here I used an array to store the pixel collision data and the canvas plugin to do the visual portion.
