Scripts

When initializing each region in the list, a function is created on the spot for it, which will be called by the trigger. For the function, the name of the region is written into a local variable using upvalues. After that, you can perform any actions with the region's name (and, accordingly, its properties) and the hero.

regions = {
list = {
["Region123"] = {active=nil, activator=nil},
...
},

init = function()
for region, props in regions.list do
  regions.list[region].enter = function(hero)
                                               local reg = %region
                                               regions.list[reg].active = 1
                                               regions.list[reg].activator = hero
                                               -- Actions with the region, access to whose properties can be found by the local name reg
                                             end
  Trigger(REGION_ENTER_AND_STOP_TRIGGER, region, "regions.list['"..region.."'].enter")
end
end,
}

regions.init()
