Yann many thanks for taking the time to look at this. Unfortunately I can't get it to work.
With WebGL enabled in Chrome and Canary I get the following log:
WebGL: INVALID_VALUE: texImage2D: no canvas
With WebGL disabled I get this alert:
Javascript error!Uncaught Error: InvalidStateError: DOM Exception 11http://localhost:50000/Polygon_plugin.js, line 231 (col undefined)This is either a bug in Construct 2 or a problem in a third party plugin or behavior - please report it to the developer!
Any help would be great! Thanks again!
