I've just released (beta) support for the Oculus Rift in Leadwerks Game Engine. The implementation was much simpler than I expected, and isn't intrusive at all in our game structure.
Previously, I wrote about my experience trying Valve's VR room. Since then, I graduated from my MBA program and moved up to Seattle to be closer to the PC gaming industry. (Previously, I lived an hour away from Silicon Valley, but it's more mobile-centric there.)
I've just released (beta) support for the Oculus Rift in Leadwerks Game Engine. I am targeting the latest OculusVR SDK and not SteamVR at this time, but I am definitely open to adding support for a range of hardware. The implementation was much simpler than I expected, and isn't intrusive at all in our game structure. To enable VR in any game, you just add the Window::VRDisplay flag in the creation flags in the Window::Create() function:
Window* window = Window::Create("My VR Game",0,0,1024,768,Window::Titlebar|Window::VRDisplay);
Or in Lua:
local window = Window:Create("My VR Game",0,0,1024,768,Window.Titlebar + Window.VRDisplay)
Head tracking and rotation are just automatic, and it works with pretty much any game. Of course, you likely will want to adjust your control scheme for VR mode, as I find bad controls to be the biggest offender of nausea inducement.
I added the following commands for extra control over the simulation:
Vec3 VR::GetHeadRotation()
Use this to modify the way your controls work. For example, use the player's head rotation to change the direction they move in when a key is pressed. You do not need to rotate the camera yourself, as this is done automatically.
Vec3 VR::GetHeadPosition()
If you do any line of sight tests this would be useful.
void VR::Recenter()
Recenters the headset orientation according to the current position and rotation.
void VR::HideWarning()
Disable the Oculus warning popup, typically by pressing space or another key.
Overall, I found the Oculus Rift DK2 to be a big step up from the DK1, but the speed and tracking are still behind SteamVR. With the DK2 I sometimes get that feeling of presence, but as soon as I start to get into it the illusion is often broken with bad tracking or lag. I'm sure this will keep improving and I look forward to seeing what the final consumer hardware looks like.
