Controller Input Restrictions

[yuki-naka4423]

Hello!

I'm currently trying to separate controller inputs based on specific actions.

For example, I'd like to prevent an object from being grabbed with a trigger input, but still allow the Ray to interact with Widgets.

Is it possible to configure inputs in this way?

Hi @yuki-naka4423!

Yes, this is possible! We can do it in 3 steps.

Step 1 - Set up Auto Possess in the Sample Pawn

Note that we're already possessing the Sample Pawn in our sample scene, but this seems to need to be set explicitly in order for the next steps to work. I've taken note of this and will update the sample scene so this is set by default.

• Open the Content Drawer with Ctrl+Space. In the Content Drawer, navigate to All > Plugins > OculusInteractionSamples > Blueprints and open IsdkSamplePawn.
  • (Note that for this step, you may need to enable “Show Plugin Content”. Click the “Settings” button in the top right, and check “Show Plugin Content”)
• In the Components panel, select “IsdkSamplePawn (Self)"
• In the details panel, in the “Pawn” category, change “Auto Possess Player” from “Disabled” to “Player 0”

Step 2 - Unbind Trigger From Ray & Grab

• Open the Content Drawer with Ctrl+Space. Navigate to All > Plugins > Meta Interaction SDK > Inputs and open IMC_IsdkHand
• In IMC_IsdkHand, locate the entries for “IA_Left_HandPinchGrab” and “IA_Right_HandPinchGrab” and delete the respective “Oculus Touch (L/R) Trigger Axis” keys.

This will unbind the trigger input form the Input Action that drives the default ray and pinch grab behavior.

Step 3 - Bind Trigger to Ray Select

• Back in the IsdkSamplePawn blueprint, add the following nodes via the tab menu: IA_Left_HandPinchSelect and IA_Right_HandPinchSelect.
• Expand both nodes by clicking the down arrow icon at the bottom of the node
• From the component panel, drag the IsdkControllerRigComponentRight component into the event graph. Drag off a pin from the resulting node and select “Get Ray Interaction”. Drag off a pin from that node and select “Get Ray Interactor”. From the Get Ray Interactor node, drag off a pin and choose “Select”, and another pin and choose “Unselect”. Connect the IA_Right_HandPinchSelect “Start” execution pin to the “Select” node. Connect the Canceled and Completed execution pins to the “Unselect” node. Repeat this instruction for IA_Left_HandPinchSelect and IsdkControllerRigComponentLeft.
  • (Note that I've pasted these nodes here if you just want to copy/paste: https://blueprintue.com/blueprint/1c44lwrl/)

Note that we're using the HandPinchSelect input action here just because it's already set up. You could use your own input action here if you like.

Let me know if you have any trouble following these instructions, hope this helps!
