Hi! I have some music in my game. Each song have a constant bpm (beats pro minute). I added some models with alpha textures in my level (thats my spotlights).

Now my problem:

If I play my music, the spotlights (models) should be rotate exactly to the beat(speed) of the current song, like a lightshow or a music-visualization.

Its a time problem, because the frametime in the engine is variable and I need a constant time for my beat.

I thought, that an equalizer is very helpful for this. I find "Fmod wrapper", but I cant download it.

Can someone help me?


Regards

You can adjust the timing very close with time_step. Don't use time_frame for this. Also total_ticks could be helpful for your problem.

Yes, I test it with time_step in the next time. ;-) But I dont understand, why is the total_ticks helpful for my problem? Can u give me an example code ?

Regards

total_ticks counts the number of ticks, ie.e 16st of seconds, passed since game start. So if you have a track with 120 bpm this makes 2 beats per second, i.e. you have a beat every eight ticks. You can now switch your lights by watching if total_ticks modulo 16 is greater than 8 or lower. Switch it off for lower values and on for values greater than 8. This way you get a light, that is off for the first beat and on for every second beat.

many thanks
