Customise how borders work

[XHawk87]

• Make border changes only take place at TC and after wait time
• Allow military land units to claim border tiles within city radius
• Prevent invaders from using captured infrastructure until TC and after wait time

[XHawk87]

This could be done like this:

• Turn off restrictinfra, we're going to simulate this another way
• Create a new flag extra that confers tile ownership
• Create a new civilian resistance unit
  • Very weak
  • Can't move
  • Discreet graphics - Looks like a flag or something?
  • No ZoC
  • Can't be bribed
  • Can't be disbanded
  • Unhomed
  • No upkeep
• Create restricted variants of roads, rails and maglev with no move bonus
• When a civilian resistance unit is defeated, the flag extra is destroyed, and any roads, rails or maglev are replaced with their restricted counterpart
• At TC, flag extras appear
  • In all owned tiles not under foreign occupation
  • In foreign tiles under your military occupation within your city working radius
• At TC, civilian resistance units appear in all tiles where you control a flag extra
• At TC, restricted infrastructure not under foreign occupation are replaced with their normal counterparts
• Wait time:
  • Record the time when units are last defeated for each tile
  • At TC, on tiles where a unit was defeated:
    • Don't plant flags if within X timeframe
    • Don't unrestrict infrastructure if within X timeframe
    • Delete old records outside of X timeframe
  • On pulse events, if X timeframe expires from when a unit was defeated:
    • Plant a flag for current owner, if not under foreign occupation
    • Plant a flag for occupier, if within their own city working radius
    • Create a new civilian resistance unit, if there's a flag
    • Unrestrict infrastructure, if there's a flag
    • Delete time record for tile
