It works really well for separating<br> the blocks, buttons, etc. from the actual graphics drawn by the Turtle. But<br> I am at the point where the turtle graphics performance is not adequate.<br> <br> The problem is, each time I draw, the accumulated rendering gets redrawn,<br> so over time, the turtle crawls along. Further, even when I first start<br> drawing, the performance is more than 100% slower than drawing directly to<br> the canvas.<br> <br> I'm doing what I think it recommended practice by Easeljs:<br> <br> turtleCanvas = new createjs.Shape();<br> stage.addChild(turtleCanvas);<br> <br> various calls of the sort:<br> <br> turtleCanvas.graphics.moveTo<br> turtleCanvas.grpahics.lineTo<br> <br> I've trted using cache to cache the shape, but that seems to be even slower.<br> <br> Just writing to the canvas context is much faster, but I don't know how to<br> combine the two worlds.<br> <br> Any suggestions?<br> <br> The code in question is in turtle.js in<br> <a href="http://github.com/walterbender/turtleblocksjs/js" rel="noreferrer" target="_blank">github.com/walterbender/turtleblocksjs/js</a><br> <br> -walter<br> <br></blockquote></div></div></div></div></div></span></div> <br></div></div>_______________________________________________<br> Sugar-devel mailing list<br> <a href="mailto:Sugar-devel@lists.sugarlabs.org" target="_blank">Sugar-devel@lists.sugarlabs.org</a><br> <a href="http://lists.sugarlabs.org/listinfo/sugar-devel" rel="noreferrer" target="_blank">http://lists.sugarlabs.org/listinfo/sugar-devel</a><br> <br></blockquote></div><span><font color="#888888"><br><br clear="all"><div><br></div>-- <br><div data-smartmail="gmail_signature"><div dir="ltr"><div><font><font>Walter Bender</font></font><br><font><font>Sugar Labs</font></font></div><div><font><a href="http://www.sugarlabs.org" target="_blank"><font>http://www.sugarlabs.org</font></a></font><br><a href="http://www.sugarlabs.org" target="_blank"><font></font></a><br></div></div></div> </font></span></div> <br>_______________________________________________<br> Sugar-devel mailing list<br> <a href="mailto:Sugar-devel@lists.sugarlabs.org" target="_blank">Sugar-devel@lists.sugarlabs.org</a><br> <a href="http://lists.sugarlabs.org/listinfo/sugar-devel" rel="noreferrer" target="_blank">http://lists.sugarlabs.org/listinfo/sugar-devel</a><br> <br></blockquote></div><br></div> </div></div></blockquote></div><br><br clear="all"><div><br></div>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><font><font>Walter Bender</font></font><br><font><font>Sugar Labs</font></font></div><div><font><a href="http://www.sugarlabs.org" target="_blank"><font>http://www.sugarlabs.org</font></a></font><br><a href="http://www.sugarlabs.org" target="_blank"><font></font></a><br></div></div></div> </div></div>
