And I tried 3 types of make noise function, but none of them AI not hear. With more than nine billion transistors, it delivers 32 deep learning TOPS (trillion operations per second), as well as more than 10X the energy efficiency and 20X … If this is the first time you heard about Perception AI System you might be pleased to know that UE4 has a set of ready-to-use functionalities that let you easily extend your AI with senses like sight and hearing.

UE4のAIコンポーネントには視覚や聴覚がひとまとめになった「Pawn Sensing」と呼ばれるコンポーネントがあります。 このコンポーネントの便利なところは視野範囲（広さ、角度）、聴覚範囲が設定出来るところです。これにより少し面倒な視野範囲の計算だったり視認時の距離チェック等が不要になるため非常に手軽に扱えます。 しかし、このコンポーネントには「視野内にキャラクタが入った」というイベントは受け取れますが、「視野外にキャラクタが出た」「見失った」というイベントまでは取得 … Press J to jump to the feed. Then, we have to add at least an element in the array “Register as Source for Senses”: it will define which senses are affected by this source.
