问题描述
错误CS0136：无法在此范围内声明名为ter的局部变量，因为它会给ter赋予不同的含义，ter已在子范围内用于表示其他内容
案例2：
地形ter =（地形）terrain.GetComponent（typeof（Terrain））;
if（ter = = null）{
返回;
}
TerrainData ter = ter.terrainData;
terrain.splatPrototypes = terData.splatPrototypes;
EditorGUILayout.Separator（）;
float mouseX;
EditorGUILayout.BeginHorizontal（）;
GUI.skin = terrain.guiSkin;
GUILayout.Label（纹理坡度）;
我试过的：
i在我收到更多错误后尝试将tre更改为其他名称。
error CS0136: A local variable named `ter' cannot be declared in this scope because it would give a different meaning to `ter', which is already used in a `child' scope to denote something else
case 2:
Terrain ter = (Terrain) terrain.GetComponent(typeof(Terrain));
if (ter == null) {
return;
}
TerrainData ter = ter.terrainData;
terrain.splatPrototypes = terData.splatPrototypes;
EditorGUILayout.Separator();
float mouseX;
EditorGUILayout.BeginHorizontal();
GUI.skin = terrain.guiSkin;
GUILayout.Label("Texture Slope");
What I have tried:
i try to change tre to some other name after i am getting more errors.
推荐答案
TerrainData ter = ter.terrainData;
应该是
It should be
TerrainData terData = ter.terrainData;
因为之后你正在使用 terData 变量。
because you are using a terData variable afterwards.
Terrain ter = (Terrain)terrain.GetComponent(typeof(Terrain));TerrainData ter = ter.terrainData;
类型 ter = ... 表示新变量必须创建类型（此处为Terrain或TerrainData）类型。但是在 TerrainData ter = ... 中，在相同（或外部）范围内已存在 ter 类型的变量，因此它可以这样做。
给第二个'ter'一个不同的名字： TerrainData data = ter.terrainData; 例如。然后在任何需要的地方使用数据变量。
您说的是在尝试时遇到更多错误另一个名字;如果上面的步骤是您尝试过的但它会出错，那么请阅读错误（如果需要，可以进行Google搜索）并找出代码有什么问题。
Type ter = ... says that a new variable of type Type (here Terrain or TerrainData) has to be created. But at TerrainData ter = ..., there already exists a variable of type ter in the same (or the outer) scope, so it can't do that.
Give the second 'ter' a different name: TerrainData data = ter.terrainData; for example. Then use the data variable wherever you need it.
You speak of getting "more errors" when you tried another name; if the above step is what you tried but it gives errors, then read the errors (maybe do a Google search if necessary) and figure out what's wrong with the code.
