PlayMaker Help / uGuiVrGazeButton on Ecosystem
« on: November 06, 2017, 07:08:39 AM »
I've downloaded the uGuiVrGazeButton from the Ecosystem and it works great if I'm just using the mouse pointer. Now I'm trying to use it with a Oculus headset, either with a standard camera or on a Oculus camera rig but it's not quite working, the Raycast is not centre to the camera, it ends up hitting somewhere below centre.

I don't fully understand the 'Rect Transform World to Screen Point' action and how the Screen Position relates to the Camera in World space.

Can anyone help?

Thanks in advance.

PlayMaker Help / Raycast for UI elements [SOLVED]
« on: October 26, 2017, 03:14:44 AM »
Hi all, I've been using a Raycast on a camera and pointer to select/interact with gameObjects which works fine. I want to use a similar method for UI elements. From what I understand I need a Graphic Raycaster but that doesn't seem to be in Playmaker or the Ecosystem. Am I missing something?

I've looked at using GUI Element Hit Test but it seems a bit backwards as I have to attach to every UI element, rather than just once to the camera/pointer. Also, I have to add an old GUI Texture component to each element.

Many thanks, Andy

VR Help / Load Level using Steam VR
« on: July 11, 2017, 03:33:44 AM »
Hi all,
I'm using 'Load Level' on a SteamVR project. Every time I load a new level I see the Steam VR compositor\loading screen for half a second or so, when what I am after is just a black/blank screen.

From what I understand I need to use SteamVR_LoadLevel but I've no idea how to make that work with Playmaker.

Can anyone help?

Many thanks

PlayMaker Help / 1 action for multiple game objects
« on: October 28, 2016, 10:00:51 AM »
What I'd like to do is set the position of 20 gameObjects to the same  position on a single event. The only way I know of how to do this is to create 20 separate 'set position' actions for every gameObject which seems crazy.

Is there a better way to do this?

Thanks in advance.

PlayMaker Tips & Tricks / Google Cardboard GazeInput using Playmaker
« on: March 20, 2016, 12:38:49 PM »
Posting here as a follow on from another thread, where I ran into a wall -;topicseen#new

Following the steps from the previous post:

1. Whatever object you wish to turn into a gaze trigger, make sure it has a Collider component. Note that you *don't* have to check "IsTrigger"--it will work anyway.

2. Attach Playmaker's Raycast action to an FSM in the MainCamera inside Cardboard's Head object.

3. On the Raycast action, set Direction to X: 0, y: 0, Z: 1. This makes the raycast always aim directly forward from the Main Camera.

4. Set the Hit Object and Hit Event to any variables you like, and you're done!
*This is where I am going wrong.

In a really simple example, I have a cube and I have used Playmaker to set up 2 states. Using Set Material colour, mouseEnter is red, mouseExit is black. This works fine pre Cardboard. After Steps 1-3, what do I need to do to make this work with GazeInput and Gaze click?

Much appreciated if anyone can help.
