Hello I come posted to you because I have a problem with my code, before it worked well with a Zorder problem but it is fixed only, my current problem is that I got confused with my backups, I started a game again and now the mix does not respect my waiting time before starting, nor the duration of the mix, it starts directly and never stops… if a great javascript coder could help me, thank you in advance, It’s too big for a picture so here, sorry…and i speak french but I made a translation for you
