You may "comment" out certain lines by adding a // or # at the beginning of the line. The bot will not perform any goals or scripts written on a commented line.
This is a good way to remind yourself what a line is meant to do, eg:
// Tell my bot not to fire any hero I capture of lvl 100 or higher keepcapturedheroes any:level>=100 // Tell my bot to farm lvl 5 npcs config npc:5
It is also a good way to temporarily turn off a feature in your goals, eg:
// Disable the next line temporarily until I get around to porting my city... #keepresource AnotherTown w:20000000,i:20000000 5000000
I also use comments to seperate my goals into sections, eg:
// resource stuff config trade:1 tradepolicy /type:food /min:3d /batch:1m tradepolicy /type:wood /min:10m /max:30m /batch:1m /allowselltomin tradepolicy /type:stone /min:500m /batch:1m tradepolicy /type:iron /min:10m /max:30m /batch:1m /allowselltomin tradepolicy /type:gold /min:100m keepresources hubcity w:25m,i:25m,f:700m 10m // hero stuff config hero:20,keepatthome:1,feastinghallspace:1 keepheroes any:level>=100|any:base>=65 keepcapturedheroes any:level>=100|any:base>=70 traininghero bigdude 120 180 0 // farming stuff config npc:5,buildnpc:5 npcheroes 5 any,!bigdude
