Hi I am a beginner programmer (Blitz) and have completed a few simpe games, but would like to tackle a simple rhythm action game... however, my mind has completely hit a blank when it comes to this. If I was to have a main track as a stream (ogg, mp3 or wav) - I just have no idea how to syncronise whatever objects (sprites or 3d models) to appear on screen in time to prompt the player what key to press, or how to judge the player's timing. Are there any articles I could read about this stuff, or does anyone have any advice? Many thanks!
