Recently i made a battle game mode with this system and it works very well
so i decided to give a guide on how to make a map selection system since i havent seen it on here before.
Selection
first make atleast 2 buttons then a counter here is an example from my map of how the settings look
button 1
you are going to want to add a text countdown like this
have a repeater repeat a task 41 times
make a counter that starts at 40 and has a target number of 0
make the counter update a property and then when the counter reaches 0 you need to send a message to do a check that checks that if the stage property equals 1 it sends a message on one channel and if equals -1 it goes on another. then make 2 relays then make it relay when receiving on those 2 channels. once you have done that make it send a message on a channel that when recieved a teleporter teleports the players to a stage
the property is for some block code (its simple VERY simple so dont worry!)
Welcome to the forums mate!
Its chaos here, but you will get used to it.
Of course, there are rogue users impersonating others and posting off-topic content.
Hope you have a great time here and rank up in the Trust Levels!
Good first guide though.
