  • You should always include delta-time (the time since the last tick) in movements. For example, use

    Rotate 90 * dt degrees clockwise

    If you rotate 1 degree per tick like you had, at 10fps it rotates 10 degrees a second, and at 60fps it rotates 60 degrees a second (6 times faster). So to make games move at the same rate you always need to use dt. In the above example, it rotates 90 degrees per second regardless of the framerate.

    When you set the timescale to 0, dt becomes 0 as well, so movements using dt also stop.

  • I had a quick look, but are you aware that triggers only run if all their parent events are true too?

    For example, you have 'On B pressed' as a subevent to "Layer ItemSelection is visible". If that layer is not visible, the 'On B pressed' trigger won't fire.

    Can you reproduce an issue with triggers which are not in subevents or do you think it's just how you've set up the events?

  • If you click Yes, does Visual Studio have any useful information in it? (Lucky you have it installed!)

  • Works fine for me on r56, Windows 7. I just nudged the ball down a bit and hit save. Did I do something wrong?

  • Space Blaster is deliberately designed to exercise hardware acceleration by having tonnes of sprites and explosions. It's perfectly possible to make games that run well even on software rendering!

  • Thanks for the ideas. We're not going to do tilemaps right away by the looks of things, but when we do, we'll come back and review these ideas and talk about it with everyone to make sure we do the right thing :)

  • Oh, Direct2D isn't available on Windows XP, I forgot. It's part of DX10 for Vista+ only. Duh! Well, I'm not sure how to tell then.

  • Now I think about it, it would make sense to do polygon collisions before physics really - otherwise all your physics collisions will be bounding box too!

  • Yeah, you should resize the ghost shooter window to the same size as the other tests to keep it fair.

    Firefox 4+ uses hardware acceleration, but only if your drivers are up to date. Go Firefox menu -> Help -> Troubleshooting information, and under "Graphics", check "Direct2D enabled" is "true".

    Firefox 6 seems a fair bit faster than Firefox 4 - in some of my tests, it actually has come out the fastest of all browsers. Different browsers are good at different things.
