# TaskGroup::GetProgress

```cpp
float GetProgress() const
```

**注意：** 此方法当前为**空实现/桩代码**。

获取任务组的完成进度。

**参数：** 无

**返回：** `float` - 始终返回 `0.0f`（任务组为空时返回 `1.0f`）

**复杂度：** O(1)

**当前状态：** 此方法为空实现，始终返回 `0.0f`，因为 `m_completedCount` 未被更新。

**示例：**

```cpp
TaskGroup* group = TaskSystem::Get().CreateTaskGroup();

for (int i = 0; i < 1000; ++i) {
    group->AddTask([i]() { ProcessItem(i); });
}

// 显示进度（注意：当前实现始终返回 0.0f）
while (!group->IsComplete()) {
    float progress = group->GetProgress();
    printf("\rProgress: %.1f%%", progress * 100.0f);
    Thread::Sleep(100);
}
printf("\n");
```
