AC & WWise - Any integration to easily trigger events in action lists?

AC Ver: 1.70.4
Unity Ver: 2019.2.4f1

Hello,

Before I go delving into custom actions, is there any existing integration for using WWise events inside action lists?

Thanks!

    So I've written a custom action that seems to do the job for now. It's not very elegant, could be a lot better, but it will play a WWise event assuming you type the correct names.

    Ideally this would offer a drop down selection of all the available WWise events and then you just select the one to use, but I've no idea how to do that!

                // (Optional) Return a string used to describe the specific action's job.
    
                return string.Empty;
            }
            #endif  
        }
    }
    
  • There's a lot of fat you can trim here, since you have no need for Skip or SetLabel functions. Here's something a little easier to manage:

    using UnityEngine;
    #if UNITY_EDITOR
    using UnityEditor;
    #endif
    
    namespace AC
    {
    
        [System.Serializable]
        public class ActionPlayWWiseEvent : Action
        {
    
            public string WwiseEvent;
            public GameObject gameobject;
    
            public ActionPlayWWiseEvent()
            {
                this.isDisplayed = true;
                category = ActionCategory.Custom;
                title = "Play WWise Event";
                description = "Plays an event from WWise";
            }
    
            override public float Run ()
            {
                AkSoundEngine.PostEvent(WwiseEvent, gameobject);
    
                return 0f; //Action only happens on one frame
            }
    
            #if UNITY_EDITOR
    
            override public void ShowGUI ()
            {
                // Action-specific Inspector GUI code here
                WwiseEvent = EditorGUILayout.TextField("Wwise Event:", WwiseEvent);
                gameobject = (GameObject)EditorGUILayout.ObjectField("Game Object:", gameobject, typeof(GameObject), true);
    
                AfterRunningOption ();
            }
    
            #endif
        }
    }
    

    Ideally this would offer a drop down selection of all the available WWise events and then you just select the one to use, but I've no idea how to do that!

    I'm not familiar with WWise myself, but if you know in advance what the events are you can just create a string array:

    using UnityEngine;
    #if UNITY_EDITOR
    using UnityEditor;
    #endif
    
    namespace AC
    {
    
        [System.Serializable]
        public class ActionPlayWWiseEvent : Action
        {
    
            public int eventIndex;
            public GameObject gameobject;
    
            private string[] WwiseEvents = new string[] {"One", "Two", "Three"};
    
            public ActionPlayWWiseEvent()
            {
                this.isDisplayed = true;
                category = ActionCategory.Custom;
                title = "Play WWise Event";
                description = "Plays an event from WWise";
            }
    
            override public float Run ()
            {
                string WwiseEvent = WwiseEvents[eventIndex];
                AkSoundEngine.PostEvent(WwiseEvent, gameobject);
    
                return 0f; //Action only happens on one frame
            }
    
            #if UNITY_EDITOR
    
            override public void ShowGUI ()
            {
                eventIndex = EditorGUILayout.Popup ("Select event:", eventIndex, WwiseEvents);
                gameobject = (GameObject)EditorGUILayout.ObjectField("Game Object:", gameobject, typeof(GameObject), true);
    
                AfterRunningOption ();
            }
    
            #endif
        }
    }

    Ah thanks @ChrisIceBox, that is definitely a nice clean up. I remember it was only a few months ago I was terrified at the prospect of trying to write custom actions for AC, but it's one of the most powerful ways to extend it. I love it.

  • Hi @Temmy! How are you? I was wondering if you could share some of your experience with AC and Wwise.

  • This script is awesome! I just tried it yesterday and it solved a major problem I was having using Wwise. Was there ever any upgrades to it?

    Thank you.
