UE5增强输入持续游戏手柄摇杆绑定

Question

我想要的行为是游戏手柄左摇杆 2d 向量将在其最新位置的每个刻度处发送输入，无论它是四处移动还是已返回到 0。

• 当我

  EnhancedInputComponent->BindAction(AimAction, ETriggerEvent::Started ...

  时，每次摇杆移动超过驱动阈值时，我都会收到 1 个事件 - 不太酷，因为当摇杆位置发生变化或返回到 0 时，我不会收到更多事件
• 当我

  EnhancedInputComponent->BindAction(AimAction, ETriggerEvent::Ongoing ...

  时，我根本没有收到任何事件。
