Suggestion: Add Multiple Flags Per Siege

[Goosius1]

Background

• With current code, battles take place very close to a town, but not inside:
• Some players then naturally want to "invade" the town during the battle, but SW does not currently support this.
• While the idea of town invasion is potentially feasible in SW (see Suggestion: Add option to require town invasions to win sieges #621), the required algorithm looks difficult to achieve, and has not even been developed yet.
• Furthermore, while requiring towns-invasions can work well (Event War has a good design for this), there are a few downsides to the idea generally, for example it inevitably causes battlefields to be more constricted (simply due to the nature of urban warfare), and there is a risk of Obsidian-Cube-towns or the like.
• Thus instead of putting effort into supporting town invasions, this ticket suggest that SW should play to its strengths, and actually "Lean in" to open battlefields
  • It looks like SW can achieve this very effectively with a surprisingly simply adjustment -> By creating multiple banners/flags for a siege, and placing some of them randomly in the wilderness near the town.

Details

• Rename "Siege Banners" to "Flags
• Starting siege:
  • When siege starts, all new locations of the flags are generated, on a radius around the Besieged town homeblock.
  • Any wilderness square.
  • In the square flag is usually at random location inside it
• Flags. Configure:
  • Number of flags - default 7 : Flag A, Flag B.....etc.
  • Percentage chance that a flag will be on besieged town border - 20%
  • Max distance from homeblock: 1,500
• Siege Zone
  • This extends around every flag. No building in claims within 32 blocks
• Terrain protection
  • Because flags are randomly placed, we cannot rely on attacker to put them in nice places
  • Being anywhere, it may be necessary to remove some automatic terrain protection features
  • Consequently, it would become even more important to add rollback after sieges / battle sessions, probably
    of the whole siegezone.....
• Dynmap
  • Would show all the flags obviously, and the letters could be shown on the first ? line
• Capturing flags
  • Flags can no longer have multiple cappers (too complicated probably)
  • Instead it is enough for one person to capture one
  • Terms: "Siege on X: The attackers are at Flag B"
  • Terms: "Siege on X: The attackers have captured Flag A"
• Timed point gains
  • These may need to increase......because without multiple cappers, even with 5 flags captured, the timed points would be generally much less than before.
• Static Points?
  • Maybe this is a chance to hardcode all the points configs????.......because unlike Money amounts, it could be that there is an optimal cross-server configuration of point gains...... In which case, it would help everyone to hardcode it.......
• Server Mod Rules
  • IMPORTANT: A server must have a rule forbidding empty spaces inside towns or this feature would break.
• Terrain Protection
  • Because most or all of the flags wi
• NOTES
  • The feature should work well with anything which enchances tactics and maneuvres on the open battlefield
  • e.g. TownyCombat 4.0.0

• Important note:
  • Multiple flags will have to work differently in TownyProvinces
  • Because with TP there are no rules against donut claiming, therefore a purely random flag placement could end up placing a flag in a donut of claims, which would require staff work to sort out, and would cause tension as staff would have to decide where to reposition the flag
  • Instead with TP a good solution might be to place all the wilderness flags on the province border.
