Well i kinda want to make a game on byond that has the same gameplay as tactics arena online so that means tunbased but not just 2 player

There will be like 3 teams
red blue and green for example
and u can have like lots of people on 1 map at the same time taking their turns moving towards someone and attacking if they are a warrior they will ahve to be like 1 space away but if they are mage they can be like 5 spaces etc

how do i make thi turn based system similar to tactics arena online
any help wuld be nice

also i just started coding so i dont know much ...

thanks in advance
