Map Generation Library

r19929 !Fix SimpleGroup? and RandomGroup placement retries (Phab:D249, #4294)

Tutorial Maps

r20084, r20085, r20086 Convert the Introductory Tutorial to a tutorial map
r19998 Fix tuturial being stuck (#4696, #4697)


r20001 Shadow map quality option (#4351, #743)


r19951 (and a few more later) Allow the AI to load custom templates (follow-up to #2951) (Phab:D693 )
r19952 Allow using {civ} in builder lists when some civs don't have those templates without errors (Phab:D707 )
r20035 Fix an assertion failure when closing the game in the map loading scren (#4154)
r20067 Add a window icon (#4363)
r20120 Allow specifying the gravity affecting projectiles

This allows for different flight paths (eg mortars, magical projectiles).

To keep the same behaviour as previous iterations of the game add <Gravity>9.81</Gravity> to the <Attack> tags of your templates.

r20141 Add -unique-logs parameter to make debugging of OOS issues locally easier
r20181 Move placeable templates out of special/.

Specifically special/territory_pull is now other/territory_pull, and special/trigger_point_[A-K] are trigger/trigger_point_[A-K], update your map xml files and trigger scripts accordingly.

This is part of a change from a placeable filter approach (where one has to explicitly list all folders/templates that can be placed in atlas) to an unplaceable filter approach. This should make it easier for modders to use a different folder structure than the public mod, and having it work without any changes. We assume that adding unplaceable templates happens less often and that modders will notice if they can suddenly place something they added that shouldn't be placeable.

r20196 Add FloatDepth? property to Position.

This allows to have amphibious units that swim at a certain depth.

To keep the current behaviour add <FloatDepth>0.0</FloatDepth> to all <Position> tags of your templates (probably as high up in the inheritance hierarchy as possible).

r20203 Move damage types definition to a helper similar to how resources are handled.

This should make it somewhat easier to add new damage types. (See #4801 for more improvements.)

r20204 Delayed damage. Can be used for grenades or similar. (#1911)

To keep the current behaviour for ranged attacks add <Delay>0</Delay> to the <Ranged> tag of your <Attack> tags.

r20215 Remove special_units/ by using inheritance.
r20241 Move formation templates from formations/ to special/formations.

Part of the placeable/unplaceable restructuring.

Make the same moves for your mods, also update all templates specifying formations (<Formations> tag within <Identity> tags).

Update your civ.json files. Prefix special/ for all entries in the "Formations" property array.

r20242 Move special_filter/ templates to special/filter/.

Move any filters you have in your mod to the new folder.

r20244, r20252 Make rubble non-decaying by default.

If your mod specifies rubble in <SpawnEntityOnDeath> (within <Health>), or elsewhere you should prefix those occurences with decay|. Specify different decay settings in the individual rubble templates, the decay| filter just activates the decay.

See the commit for a *nix one-liner to make this change for you. (As always check the end result, and use a version control system.)

r20246 Switch back to an unplaceable filter for templates.

This makes rubble/ placeable.

The only unplaceable templates from now on start with template_ or special/. All other templates now show up in Atlas, and in code queries for all templates.

Allows using different template organization schemes (subfolders, different folders, etc).

r20249 Command line options can now start with - or --.

Performance Optimizations

r20256 Fix lag from moving to the edge of the map
r20438 Fix lag from sinking ships (#4713)
r20630 Improve Hierarchical Pathfinder Update, somewhat substantially on larger map sizes
r19936 Stop copying the territory grid when recomputing the texture.(Phab:D741 )
