Unity Addressable 实现Build时自定义剔除资源组

核心原理

重写BuildScriptBase的ProcessGroup,让其在需要剔除的时候返回string.Empty或null即可

代码实现

先写一个Schema来给需要管理的Group上标记

csharp 复制代码

using UnityEditor.AddressableAssets.Settings;

public class BuildExclusionSchema : AddressableAssetGroupSchema
{
    public enum FilterType { 
        Normal,
        TestOnly,
        ReleaseOnly,
    }
    public FilterType filterType = FilterType.Normal;
    public bool ShouldExclude() { 
        if(filterType == FilterType.Normal)return false;
        if (filterType == FilterType.TestOnly) return !CommonData.isTest;
        if (filterType == FilterType.ReleaseOnly) return CommonData.isTest;
        return false;
    }
}

随便写的，具体自己的项目里想怎么改怎么改

然后是核心，自定义一个AA的BuildMode

这里直接继承默认的BuildScriptPackedMode

csharp 复制代码

using UnityEditor.AddressableAssets.Build.DataBuilders;
using UnityEditor.AddressableAssets.Settings;
using UnityEngine;
[CreateAssetMenu(fileName = "BuildScriptPackedFilterMode.asset", menuName = "Addressables/Custom Build/Filter Build Script")]
public class BuildScriptPackedFilterMode : BuildScriptPackedMode {
    public override string Name => "Filter Build Script";
    protected override string ProcessGroup(AddressableAssetGroup assetGroup, AddressableAssetsBuildContext aaContext) {
        var customFilter = assetGroup.GetSchema<BuildExclusionSchema>();
        if (customFilter != null && customFilter.ShouldExclude()) {
            Debug.Log($"[AA Filter Build] 剔除资源组: {assetGroup.name}");
            return null;
        }
        else { 
            return base.ProcessGroup(assetGroup, aaContext);
        }
    }
}

记得重写Name属性，在各种面板上显示时都要用的
