# InputManager::IsAnyKeyDown
|
||
|
|
|
||
|
|
查询是否存在任意键盘键或鼠标按键当前处于按住状态。
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
bool IsAnyKeyDown() const;
|
||
|
|
```
|
||
|
|
|
||
|
|
## 行为说明
|
||
|
|
|
||
|
|
当前实现会：
|
||
|
|
|
||
|
|
- 如果未初始化，返回 `false`
|
||
|
|
- 先扫描 `m_keyDown`
|
||
|
|
- 再扫描 `m_mouseButtonDown`
|
||
|
|
- 任一数组里存在 `true` 就返回 `true`
|
||
|
|
|
||
|
|
这意味着当前 “any key” 的统计范围并不只限于键盘，鼠标按键也会让它成立。
|
||
|
|
|
||
|
|
## 返回值
|
||
|
|
|
||
|
|
- `bool` - 当前是否存在任意键盘键或鼠标按键处于按住状态。
|
||
|
|
|
||
|
|
## 示例
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
if (XCEngine::Input::InputManager::Get().IsAnyKeyDown()) {
|
||
|
|
// ...
|
||
|
|
}
|
||
|
|
```
