游戏的资源目录用的是assets

# make sure assets is exist
if [ -d "$APP_ANDROID_ROOT"/assets ]; then
    rm -rf "$APP_ANDROID_ROOT"/assets
fi

mkdir "$APP_ANDROID_ROOT"/assets

上面的意思是如果存在assets文件夹,就删掉重建,用于完全更新资源,避免有漏删漏更的问题

# copy resources
for file in "$APP_ROOT"/Resources/*
do
if [ -d "$file" ]; then
    cp -rf "$file" "$APP_ANDROID_ROOT"/assets
fi

if [ -f "$file" ]; then
    cp "$file" "$APP_ANDROID_ROOT"/assets
fi
done
