Hey, i have an idea, an idea that could be interresting. The command to spawn a mob is really cool, but have a huge limit. there is the problem :S Hou have to spawn a mob where you are? - Ok just enter the command in the chat. Hou have to spawn a mob in a specified world? Ok enter the coordinates + the world Hou have to spawn a mob into a unspecified world with command block? C'ant So, i had an idea, the command to spawn a mob at specified location lookslike that: /mm mobs spawn <mob> 1 <world>,x,y,z And i'm asking to an improvment like that: /mm mobs spawn <mob> 1 <thisworld>,x,y,z (if world unspecified) So in real term, the global command would look like that: /mm mobs spawn <mob> 1 x,y,z #(if you don't specify the world, the mob will spawn at the coordinates, but from the world were the command has been entered) So, you should ask me "Why the f*ck do you want to not specify the world?" The reason is simple, i have a huge server where i have some dungeons, thoses dungeons have many commands blocs and the total configuration is too long to explain here but, when a group of players enter into one of thoses dungeons, a copy of the dungeon's world is created where the group is alone in. It create a 'false world' where they could start the dungeon, activate command blocs, destroy the map if they want, without modify the former map. And doing it again and again. The problem here is the false world created have the name of the former world-1 (example, Antarion is the real dungeon name, a player enter in, a world Antarion-1 is created) So, actually all commandBlocs have the "Antarion-1" specified to spawn the mobs, so it works ... yes, until another group of player wants to enter the dungeon too. If another group of player wants to enter into the dungeon, another world is created, named "Antarion-2" And then all commands blocs are inefective, because they will spawn the mobs into the first opened dungeon. It's a hard problem, because here it's just if there is 2 groups in the same time, but actually it's more a 7/8 group in the same time than 2 ... I had to open only 1 dungeon for everyone, and eachs groups have to wait the end of the first group etc etc, i'ts not reliable. So, could you add a command like that /mm mobs spawn <mob> 1 x,y,z If world unspecified, it would spawn into THIS WORLD Thanks for reading.
