# city sample

[city sample](https://www.unrealengine.com/marketplace/ja/product/city-sample)

ニューヨーク(NY)をモデルに都市が作られています。人と自動車が動いています。自動車は乗ることや破壊することができます。

## game animation sampleとの統合

他のassetとの統合を考えるとき、city sampleをベースにします。なぜなら、city sampleは複雑すぎるためです。ここではcity sampleをinstallした上で、game animation sampleをそこにcopyします。

なお、`GameAnimationSample/Binaries/Win64/UnrealEditor.modules`だけはcopyしません。

```sh
# 以下のfileをcopy
GameAnimationSample
    Binaries
        Win64/UnrealEditor.modules #このfileだけはcopy(rewrite)しない
    Build
    Content
```

次に`CitySample/Binaries/Win64/UnrealEditor.modules`を編集します。

```json
{
    "BuildId": "xxx",
        "Modules":
        {
            "CitySample": "UnrealEditor-CitySample.dll",
            "CitySampleAnimGraphRuntime": "UnrealEditor-CitySampleAnimGraphRuntime.dll",
            "CitySampleEditor": "UnrealEditor-CitySampleEditor.dll"
        },
        {
            "GameAnimationSample": "UnrealEditor-GameAnimationSample.dll"
        }
}
```

これでGASPが機能すればokです。

他には`$project/Config`と`$project/xxx.uproject`を見比べてみましょう。必要そうなものを追記します。

	],
	"TargetPlatforms": [

		"Windows"

	"EpicSampleNameHash": "111"
}
```

また、`/Config/DefaultEngine.ini`に注意してください。

```sh
[/Script/Engine.CollisionProfile]
+DefaultChannelResponses=(Channel=ECC_GameTraceChannel11,DefaultResponse=ECR_Ignore,bTraceType=True,bStaticObject=False,Name="Traversable")
+DefaultChannelResponses=(Channel=ECC_GameTraceChannel12,DefaultResponse=ECR_Ignore,bTraceType=True,bStaticObject=False,Name="EnemyProjectile")
+DefaultChannelResponses=(Channel=ECC_GameTraceChannel13,DefaultResponse=ECR_Block,bTraceType=True,bStaticObject=False,Name="BulletHell")
+DefaultChannelResponses=(Channel=ECC_GameTraceChannel14,DefaultResponse=ECR_Ignore,bTraceType=True,bStaticObject=False,Name="LookAtTrace")
```

`Collision Trace Channel`は作り直さなければ機能しないことがあります。

### Gameplay Camera

例えば、camera(Gameplay)を有効にするには`$project/Config/DefaultEngine.ini`に`DDCVar.NewGameplayCameraSystem.Enable`の行を追加します。`CBP_SandboxCharacter`にある関数の`SetupCamera`を確認してください。

```sh
[/Script/Engine.DataDrivenConsoleVariableSettings]
+CVarsArray=(Type=CVarBool,Name="DDCVar.NewGameplayCameraSystem.Enable",ToolTip="",DefaultValueFloat=0.000000,DefaultValueInt=0,DefaultValueBool=True)
```

現在、[characterのcollisionが機能しない問題](/city/00_err.html)が発生します。

### Collision Trace Channel

`Collision Trace Channel`を設定するには、`Config/DefaultEngine.ini`を編集する必要があります。以下の手順で行います。GASPは`traversable`を追加します。これが追加されていないと動きません。

`ECC_GameTraceChannel${n}`に注意してください。

```sh
[/Script/Engine.CollisionProfile] 
+DefaultChannelResponses=(Channel=ECC_GameTraceChannel11,DefaultResponse=ECR_Ignore,bTraceType=True,bStaticObject=False,Name="Traversable")
```

## 他のmapとの統合

mapにはactorがまとめられているものがあり、それはmapにくっついていません。移動できない場合があります。

基本的にはA-mapとB-mapはある程度位置を完成させてからcopyしましょう。
