Hello all :)
Here's my two examples. This sample is the same on GM HTML 5 and Construct 2 with the same calculation (for moves). We can compare.
This is a moving ball test with 20 sprites at the same times. Each balls have his own speed.
Launch each sample with Opera (and only Opera because it's this browser that cause pb for me) and let it run a minute and look at the ball.
You should see that with the C2 version, ball (and espacially ball with small speed, with them, we can look at it better), movements are very loud, with some glitches, or I don't know how to say that, but with the GM HTML 5 version, and Opera, the movement is more "smooth".
But as you can see (and test it) if you launch the C2 sample with other browsers like Firefox 7 or Google Chrome or IE that's perfect !
Now here's the samples (open it first with Opera) :
The Construct 2 version : Click here to see the C2 TestBall version
The Game Maker HTML 5 version : Click here to see the GM HTML 5 TestBall version
Thank you for help :)
