This command block system makes it so whenever you die you will respawn at a location a distance away from your death location. This is really useful for any Parkour maps so you start a few jumps away from your fall or PvE maps so that if you die you do not respawn in the middle of the mobs. The system comes with its own new gamerule "/gamerule SmartRespawn 1" will turn the syetem on and "/gamerule SmartRespawn 0" will turn it off. The command block box also comes with a sign to remove the system when it needs to be removed.
Big thanks to MrGarretto who designed the command block combiner system: http://mrgarretto.com/cmdcombiner
I hope you like it and find it useful in maps. I am making a map right now that uses it so look out for that.
