  Is it slow or just not work? I'll check it out but there's no reason it should work any different than the browser.

  Version 0.3:

  [Added] load image.

  [Added] Textured quad drawing.

  --- A separate image can be loaded and then drawn distort map style. Works in both webgl and canvas2d.

  Erasing is done by pasting objects with the "destination out" blend.

  You could use a second canvas with the "destination out" blend and draw to that then paste it to the first canvas.

  The paster does this with quads. I'll have to have to consider a way to cleanly add it to the ACEs for this plugin. In the mean time you could try the methods above.

  Looking at the js files it doesn't appear to use a framebuffer. Webgl just scales better than canvas2d when drawing a larger scale.

  I just reviewed your comment and there was an issue with the "clear with color" action but it should be corrected in version 0.2.

  To fix the color make the "color" paster invisible and the "mix" paster visible. The RES stuff is working fine for me... try setting the resolution to something low like 100x100 to see the effect more readily? With linear sampling it can be very subtle at times.

  As for speed the new method is certainly faster with webgl on. With webgl off it's slower but that's only because it uses 4 canvases instead of 2.

  That method of shadows is basically what my latest examples do. The paster and canvas plugins support pasting objects with "destination out". The paster object also already allows you draw a quad with your blend of choice.

  Change the sprite's blend mode to additive and make sure it's black under them. You can then get any color.

  I fiddled around with the composition some more and put it in one of my older examples to test it out with scrolling.

  Ashley Kudos! Copy/pasting between capx' and the replace object function work great!

  The function is the same in Paster as it was in canvas. The issue here at least for me is the texture size is bigger than the max supported size of my video card. Also at least for this example you only need to cover the window not the entire layout.

  eg.https://dl.dropboxusercontent.com/u/5426011/examples19/NewLight.capx

  If you scroll just reposition the canvas accordingly.

  Updated to version 0.2

  This update adds more hotspot positions than just "center" and it adds the ability to draw colored quads with a blend mode of choice.

  With vanilla C2:

  1. Select the bottom layer and set transparent to true.

  2.Goto "Project Properties" and set "Clear Background" to "No".

  3? If "Enable WebGL" is "on" add the brightness effect to the layout.

  There you go, no clearing between frames.

  For more control you could try out the canvas or paster plugins. Both work well when webgl is off, Paster is much faster with webgl on.

  Because the pasters are just created they can't be picked from a family until the next toplevel event. A solution is to add a second "start of layout" event and move the "set resolution" action to that, or you could discard the family completely and do a "set resolution" for each paster type.

  RES isn't used, I forgot to remove it. If you want to use it just change set resolution int the start of layout to 640/RES,480/RES. It isn't used elsewhere.

  Hi,

  I converted the example to use the Paster plugin instead of the Canvas plugin so it will be much faster with webgl.

  This is the result of much tinkering and unfortunately even I have a hard time to see what I did. Basically the lighting is done with transparency and then the color is a separate canvas below so I can have finer control of the blending.

  Here is a simplified version that just has one light.

  Doesn't "wait 0 seconds" already wait 1 tick?

  From the manual:

  ne more trick: "Wait 0 seconds" postpones the following actions until the end of the event sheet.
