In Wwise, Switches represent the different alternatives that exist for a particular game object within the game. Sound, music, and motion objects are organized and assigned to Switches so that the appropriate sound or motion object will play when a change is made from one alternative to another in game. The Wwise objects that are assigned to a Switch are grouped into a Switch Container. When an Event signals a change, the Switch Container verifies the Switch and the correct sound, music, or motion object is played.
例6.2 スイッチの活用例
例えば、ファーストパーソン・シューティングゲームで、メインキャラクターが次々と変わる環境を歩いたり走ったりする状況を考えてみましょう。環境に応じて地面も変化し、コンクリート、芝生、土などの地面素材によって足音も変えていきます。In this case, you can create Switches for the different ground surfaces and then assign the different footstep sounds to the appropriate Switch. When the main character is walking on a concrete surface, the “concrete” Switch will become active and its corresponding sounds will play. If the character then moves from a concrete surface to a grassy surface, the “grass” Switch will become active and its corresponding sounds will play.
The following illustration demonstrates how the active Switch determines which footstep sound is played.
