Further Technology Hooks

[Kieran P]

We would like the following hooks into the technology system. I've attached my work for the first point, but it doesn't work because farms are initialized with a player of -1, and the technology system doesn't like that.

• Player techs should be able to modify the ResourceSupply/Amount values for their own structures (namely fields to increase the max supply through technologies like "Irrigation" and "Water Wheel" etc).

• Modify traders speed and carrying capacity

• Modify healers range, hp restore amount, and rate of healing r11679

Are the following tricky/impossible?

• Player techs should be able to modify Gaia resources (trees, animals, mines etc), without affecting another players (this might be hard without causing a desync?). I'm thinking when two different players are harvesting the same tree, and one has a tech that supplies 50 more wood per tree, and the other play exhausts the tree on their end... Not sure how to handle that.

Initial go at farm supply upgrade - not working

Philips comments on the last point (about modifying a trees max supply):

11:16 <@Philip`> k776: Instead of increasing the amount of wood in a tree (which sounds bad for lots of reasons), maybe it'd be better for units to receive e.g. 1.5 units of wood while the tree loses 1
11:16 <@Philip`> so units will eventually receive more wood than the tree nominally contains
11:17 <@Philip`> (because they're more accurate at chopping and will waste less of the wood, so they can end up with more than an average chopper would expect)
11:18 <@Philip`> Or just increase the gathering rate instead, which seems more intuitive

Seems to me then we need 3 values:

• GatheringRate (for a "Efficient Tools" tech)
• GatheringMultiplyer (for a "Efficient Mills" tech)
• GatheringCapacity (for a "Wheel barrow" tech)

Those three would supply the best combination of possible changes for resource gather.

In 11679:

Make some healer modifiable by techs. Refs #1357.

[Zilcho]

Instead of modifying the amount of wood the gaia resource have why not instead give upgrades some sort of modifier so when they gather 1 resource instead they get 2.

[Kieran P]

Hey Zilcho. Yes, that is probably the way we'll go about it. You're welcome to take a stab at implementing it if you want.

Farms will eventually be totally revamped.

See: #1318

In 11711:

Implements TerritoryInfluence/Radius tech modification. Adds C++ interface for TechnologyManager. Renames its message to MT_TechnologyModification defined in TypeList.h. Refs #1357.

[Kieran P]

Closing this as invalid. The remaining techs rely on #1358 to be implemented first.

The remaining tech needed are also listed at ​https://docs.google.com/spreadsheet/ccc?key=0AgXkx2Fjag5hdDI5bDNUZ3V5UDhvYWhvb2I2b1RJMEE#gid=0
