SteamVR Template - Controllers not operating correctly

[JacksonBrent]

In the Lua code in the SteamVR template, it is scripted that you can use the touchpad to move around inside the model.  This does not work.  Am I missing something or is this a bug?

I really need the ability to relocate to different positions on the level.

Here is a snippet of the code that should work but doesn't seem to do anything.

 -- Move character using touch pad
        if Bit.band(ctrl_buttons.pressed_buttons, SteamVR.BUTTON_TOUCH) ~= 0 then
            move = Vector3.multiply(forward_without_pitch, ctrl_buttons.touch_axis.y)

            if ctrl_buttons.touch_axis.x ~= 0 then
                local rot = degrees_90;
                if ctrl_buttons.touch_axis.x > 0 then rot = -rot end

                local rotated_forward = Quaternion.rotate(
                    Quaternion.axis_angle(Vector3(0, 0, 1), rot),
                    forward_without_pitch
                    )

                move = move + Vector3.multiply(rotated_forward, math.abs(ctrl_buttons.touch_axis.x))
            end
        end

Thanks for your help.

I will look into this.  Sit tight.

You can move around in the steam template however you like. You can set your input via flow, via lua or you can teleport. I recommend teleporting.

Use lua or flow to set your tracking space. You can do a raycast out from your controller, draw a line wiht a raycast, then teleport to that location. These flow nodes already exist and the lua funcitons are in the flow callbacks script.

function SteamVRFlowCallbacks.set_tracking_space(t)
    if not SteamVR then return t end
    
    local pose = Matrix4x4.from_quaternion_position(t.rotation, t.position)    
    local scale = t.scale or Vector3(1, 1, 1)
    Matrix4x4.set_scale(pose, scale)
    Project.play_area_offset:store(pose)
    
    return t
end

I'm a little unclear on how to connect the controller -> raycast -> Steam VR Set Tracking in flow.

I've been trying for a while but just can't get it.

Can you post a basic raycast from a controller to teleport flow?

[JacksonBrent]

This is what I have so far, but I can't seem to get it to teleport me where I have it pointing.

Hey, ok, well you have 1 thing straight off the bat that is going to pose problems.  You are going to need to have some sort of a boolean gate on your steamvr button pressed.  Otherwise it will teleport you a gazillion times when you press it.  It is firing on every level update.

What you are going to want to do is as follows.

1.  After the Steam VR Button Pressed, Add a Compare Objects Node.

2. Plug into that a Boolean Data set it to false and a Get Boolean Variable...  name it something like TeleportPermitted

3. Directly after the compare objects node, you are going to have a set boolean data node.  It should be named the same so... TeleportPermitted = False

This is now only runs the command once.

4. At the end of the teleport sequence the last thing you will need to do it set TeleportPermitted=True

Another problem i am seeing is in the logic of your design.  It looks like you are using both head tracking and controller tracking.  Im not sure what is going on there or what you ar inteneding.  If you are teleporting based on your head position, then you should just be using it.  if you are doing it based on your controller, then you should only use that.  i dont see why you are trying to use both.  Maybe i am missing something?

You will also want to use Steam VR World Pose, not local pose.  maybe that is the root of your issue.

I would actually start there.

[paulkind]

lastly i think you may need to make use of the "hit" boolean.  This way you only teleport to the position when you are intersecting somthing.  I am not entirely sure what the result will be otherwise.  I will try and build this out tomorrow when i have some more time.  i need to test a few things since i have personally never done this myslef.  For the most part you seem to be on the right track.

Here is an example:

You will raycast from your controller outward. Where you hit, on a button press you will set your tracking space. To visualize this, I've added spawning a circle mesh at the ray cast hit location and I've added a 'laser' mesh that I set the scale to the length of the ray cast. It helps to see where you are going. Your art is your choice though 🙂

It looks like you are using a more advanced version of the Steam VR plugin.  I do not have a hold option on my Steam VR button, and there are a few other things that seem different.  That being said, I got it working!  Thanks for you help.  I had to use a relay that was only latched on when a unit was not spawned in order to get my spawning model to not spawn a thousand times.

I appreciate your help and look forward to making more VR activities.

Heh, sorry about that! We've updated the flow nodes -- of course as we continue to develop. These will all be available in v1.4. Glad you got it working 🙂 The concept is the same. You an always write your own custom flow nodes or just use the lua functions.
