HTC Vive Raycast

Hi Tony & Team

Is there any way to enable a visual raycast from the dialogue system so I know where it's aiming? I'm running into a case where the Usable icon ("press spacebar to talk to this NPC") is only appearing when I look near it's head but off to the side a bit...

Second: I can't seem to customize the Usable icon. I've followed what I found on the forums in creating a Basic Standard Usable UI 1 game object and placed it as a child of my NPC but it doesn't show up in my headset. I only see the default one on my screen/monitor. I want to see it in world space so that I can see it in my VR headset.

It isn't built in. But you can write a script to do it, or add a line-shaped GameObject as a child of the camera. If you only want it to appear when a Usable is targeted, you can hook into the OnSelectedUsable() and OnDeselectedUsable() events. There are also corresponding SelectedUsableObject and DeselectedUsableObject C# events if you want to do it in code without using UnityEvents.

The Standard Usable UI is in world space. Here's an example where I've added the Basic Standard Usable UI prefab to an NPC:



Is yours positioned correctly for your NPC? Maybe it's offset really far from the NPC.
