On my Computer it's definitly not jumping more than the above and the Framerate of the lower is higher. The Movement on the lower is much smoother, as far as I can see.

The lower of the two jumps around allot, while the top one is stable throughout the game. I think the point of this was optimized and stable frame rate.

The little red Box at the top is showing constant 60 for the lower and 38-42 for the upper Version. Does this mean the old version of the game Timer is now the better solution?

I followed these tutorials and found that their technique results in phenomenal performance within the web browser when working with simple and numerously repeated bitmap sprites. However, even with their optimized game timer loop, their technique struggles with high-resolution mobile devices like the iPad. As a simple test, I compiled their optimized game timer loop for Asteroids as an iPad app after changing the canvas size to 1024×768.

i was recently experimenting with some different timer systems for individual units in this little flash game of mine. and i saw what everyone is talkin bout… some strange jittery motion on my objects (just boxes on a single color background [no blitting yet]) but during my experimentation i discovered a weird … technique.

so i got a document class that drives my main game loop timer… i got “new timer(5)” and that timer event triggers the “e.updateAfterEvent”. additionally i put “this.stage.frameRate=10;” in the constructor. which combines to make 100 fps i think

so then rather than have this document class go through and update each unit and then draw, i got three different unit classes managing themselves. one with a time sytem built around enterframe, another with a deltatime system combined with enterframe, and finally for just a weird test a class with a timer of 1 ms(additionally calculating deltatime). each one of these classes ‘time system’ calls there own respective ‘tick’ functions that move them like so
“x+=(5*dt); x=x%800;”

the strange thing is the timer(1) class moves smooth as hell, while the others move like michael j fox… what gives?

Unfortunately last December we saw that the latest Flash players started to hiccup when "update after event" is turned on. If you want a simple solution, comment out the e.updateAfterEvent() in the loop. This will band-aid the problem but your game will work. The frame rate will become a little choppy though. At the 11th hour, as the book was about to be published we had to completely re-write everything to use standard timers (plus I add in a time-based step timer) in the last few games. I was livid that we had to do this and none of my emails were returned by Adobe on the subject. I tried everything I could think of to get this to work, but nothing replicated the e.updateAfterEvent() method of smoothing out the render. The time-based step timer does this in a different way and works, but it just isn't the same.
