Few questions

[Essen]

Alright, tried it all out. Entities work, although I haven't tested them in game yet, what I have a problem is that credits stuff however. I tried out that thing via Checkpoint as you guys said, however, one problem occured. There's a corridor with script area at the end and two script areas at the start. One script area at the start stands for Checkpoint you guys told me to make. The second area starts spawning monsters chasing the player+Custom sound starts playing. Now, everything works fine until I either die or get to the end of the corridor. What should happen is, if I die, credits with what happened should start, and Custom Music should play, if I make it to the end of the corridor, different credits start, also saying what happened with protagoinist, and other, different Custom Music plays. I made script in order to stop the custom sound once credits appears. Now, problem is, it simply doesn't work. The sound just won't stop playing, it isn't set to be looping, however, it's quite long. I tried to put StopSound in different places of the script, but the sound still goes on. It interrupts the music a lot. I could solve this out for an option of making it to the end of the corridor, I would add next Script Area right before the Script Area triggering the credits, and would script it to make sound stop. However, what if I die? I can't anyhow script that, because I don't know how long it will take to player to die.
How to solve this out?
