Trigger Chat by bowing in VR

[SuperSal]

So I'm getting to the point where I will set up characters and the Dialogue System in VR. A month ago, I asked to create a chat if you remember when I asked how can I set up Skyrim, Fallout, Dishonored style chat system in Unity. So yeah,its related to that and since its a VR project I was thinking to add some interactivity. I was wondering if you can tell me how can I trigger a chat when I bow before the character to trigger chat..


Also when I will set up the question how will chose question that needs to answer, will I use Oculus Rift's touch controls to point towards the question or will scroll down from the list?


- Cheers

Hi,

Detecting the player's bow motion is outside the scope of the Dialogue System. Maybe you could use an asset such as AIRSIG's 3D Motion Gesture Recognition.

Once you've detected the bow, you can call the nearest Dialogue System Trigger's OnUse() method to start the conversation. One way to know the nearest Dialogue System Trigger is to use the Dialogue System's Proximity Selector component. Instead of "using" the selection with an input button, you'll use it by detecting the bow.

Remember that the dialogue UI uses standard Unity UI. You just need to set up your project to use Oculus Touch with Unity UI. It's not specific to the Dialogue System. You can find instructions on Oculus's site: Easy Controller Selection.

Since, time is short for me and my project is due within few days. Could you show me how can do that with the suggested VR assets?

I've never used 3D Motion Gesture Recognition. I'm just trying to help point you to resources that can help you with things that are outside the Dialogue System's scope, such as recognizing VR gestures.

For Unity UI, just follow the setup instructions in the Easy Controller Section link I provided.

Does the Proximity Selector component get put onto the player game object?

Does the Proximity Selector component get put onto the player game object?

Yes, or a child GameObject. If it's on a child, assign the main player GameObject to the Actor Transform field.

Then either the Proximity Selector or the Usables need trigger colliders. In the example below, the NPC has the trigger collider:



But you can do either way. In the tutorial, the player has the trigger collider.

I missed the part about the player needing a Trigger Collider. Once I did that, it started to work Thanks, Tony!

Glad to help!

Sorry to necropost, but this is relevant to this discussion as I'm trying to fire "use" on my NPC dialogue in the same manner that the GP mentioned, except that mine is via a different gesture.

I have the gesture working, I have a Debug.Log firing to tell me when my Proximity Selector enters the NPC's dialogue manager and also when it exits. In my code, when my gesture is detected, I do:

Code: Select all

Debug.Log (proximitySelector.CurrentUsable);
proximitySelector.UseCurrentSelection ();

Unfortunately, I get a null in my log for the CurrentUsable and, of course, the conversation does not start. If my Proximity Selector comes into contact with a Usable, should it not become the CurrentUsable?

Thank-you.

Is the NPC's Usable component enabled?

How are you doing this part?

I have a Debug.Log firing to tell me when my Proximity Selector enters the NPC's dialogue manager and also when it exits.

Have you hooked into the Proximity Selector's SelectedUsableObject(Usable) C# event or the OnSelectedUsable() UnityEvent?

I'm finishing work for the day, but I'll be back online first thing in the morning.
