Building Created Event [snippet for mod makers]

For mod makers.

What it does
This mod contains code that defines a lua event that fires off when a building is created. The event does not fire for buildings with 0 or less hammer cost unless they have a faithCost greater than zero and are enabledByBelief. The lua event provides the information you need to get the city object and the buildingclass.

If an end-user is playing with multiple mods that use this snippet it will work properly.

Compatibility
This code is compatible with Vanilla, Gods & Kings and Brave New World.

How to incorporate into your mod
The building created event will only work correctly if you are also using the unit created event snippet. A copy of the unit created event code is included in this mod.

Copy the "unit created" directory and all its contents to your mod. Have the XML file update the database (via the Action tab) and set the LUA file as an "InGameUIAddin" (via the Content tab).

Copy the "building created" directory and all its contents to your mod. Have the XML and SQL files update the database (via the Action tab) and set the LUA file as an "InGameUIAddin" (via the Content tab).

How to use
Add your functions to the "LuaEvents.BuildingCreatedEvent" event.

How it works
This code creates a new unit class for every building class. These units are named "UNIT_BCE_BUILDINGCLASS_TEMPLE", "UNIT_BCE_BUILDINGCLASS_MONUMENT" etc (BCE = Building Created Event). It then has every building provide 1 free copy of the unit class for it. The unit created snippet is used to detect when a "buildingClass" unit is created and immediately delete the unit and fire off the event.

The end user should never ever see a "buildingClass" unit. They serve no purpose other than to be detected and deleted immediately.
