3.长城相邻加成修改

这个比较复杂，要修改两处，首先要向<Improvement_Adjacencies>标签内添加加成ID。

然后要根据每个ID设置加成及生效科技，单纯添加两者中的一个都无效

第一处：邻接ID添加到<Improvement_Adjacencies>标签，相似的结构都可以添加，只是加成的条件不同罢了，当然，必须是条件类标签。

<Improvement_Adjacencies>

        <Row ImprovementType="IMPROVEMENT_FARM" YieldChangeId="Farms_MedievalAdjacency"/>

        <Row ImprovementType="IMPROVEMENT_FARM" YieldChangeId="Farms_MechanizedAdjacency"/>

        <Row ImprovementType="IMPROVEMENT_GREAT_WALL" YieldChangeId="GreatWall_Gold"/>

        <Row ImprovementType="IMPROVEMENT_GREAT_WALL" YieldChangeId="GreatWall_Culture"/>

        <Row ImprovementType="IMPROVEMENT_KURGAN" YieldChangeId="Kurgan_Faith"/>

        <Row ImprovementType="IMPROVEMENT_COLOSSAL_HEAD" YieldChangeId="ColossalHead_FaithForest"/>

        <Row ImprovementType="IMPROVEMENT_COLOSSAL_HEAD" YieldChangeId="ColossalHead_FaithJungle"/>

    </Improvement_Adjacencies>

第二处：根据ID设置加成与生效科技

<Adjacency_YieldChanges>标签与上边的<Improvement_Adjacencies>呼应。

<Adjacency_YieldChanges>

<Row ID="Farms_MedievalAdjacency" Description="Placeholder" YieldType="YIELD_FOOD" YieldChange="1" TilesRequired="2" AdjacentImprovement="IMPROVEMENT_FARM" PrereqCivic="CIVIC_FEUDALISM" ObsoleteTech="TECH_REPLACEABLE_PARTS"/>

<Row ID="Farms_MechanizedAdjacency" Description="Placeholder" YieldType="YIELD_FOOD" YieldChange="1" TilesRequired="1" AdjacentImprovement="IMPROVEMENT_FARM" PrereqTech="TECH_REPLACEABLE_PARTS"/>

<Row ID="GreatWall_Gold" Description="Placeholder" YieldType="YIELD_GOLD" YieldChange="1" TilesRequired="1" AdjacentImprovement="IMPROVEMENT_GREAT_WALL" PrereqTech="TECH_MASONRY"/>

<Row ID="GreatWall_Culture" Description="Placeholder" YieldType="YIELD_CULTURE" YieldChange="1" TilesRequired="1" AdjacentImprovement="IMPROVEMENT_GREAT_WALL" PrereqTech="TECH_CASTLES"/>

<Row ID="Kurgan_Faith" Description="Placeholder" YieldType="YIELD_FAITH" YieldChange="1" TilesRequired="1" AdjacentImprovement="IMPROVEMENT_PASTURE"/>

<Row ID="ColossalHead_FaithForest" Description="Placeholder" YieldType="YIELD_FAITH" YieldChange="1" TilesRequired="2" AdjacentFeature="FEATURE_FOREST"/>

<Row ID="ColossalHead_FaithJungle" Description="Placeholder" YieldType="YIELD_FAITH" YieldChange="1" TilesRequired="2" AdjacentFeature="FEATURE_JUNGLE"/>

</Adjacency_YieldChanges>

红字为长城相邻加成ID内容

Description="Placeholder"   此加成的种类，简单的修改可以不用管，提一句给爱研究的玩家。

YieldType="YIELD_GOLD" YieldChange="1"  加成资源，加成数量

TilesRequired="1"   邻接需求数量，几个相邻的建筑可以进行加成。

PrereqTech="TECH_MASONRY"    生效科技

<Improvement_>标签下还有很多关于长城的设置，例如观光加成，简单改动就没必要细说了。
