Trigger with VR

[Anonymous]

Hi guys,

I need to play/stop an animation when i touch the trigger with Oculus Touch controller or just touch the trigger.

I really don't know code at all, sp, i try to do my best to archive that, but still have some issues:

That is my trigger:

And this is my Flow:

I'm using Oculus Rift with toutch controller to play around in the scene, my animation Works fine, the problem is, when i toutch the trigger, my screen freeze and I receive this error message:

localhost / Lua: [string "..."]:68: Accessing a deleted unit.

I really don't know what i need to do to fix that.

When i touch the trigger, with Oculus Toutch, my animations needs to stop, and when I move my hands out of the trigger, my animation needs to resume.

If anyone have something to help me, thanks.

you need to attach/constraint a proxy mesh with an actor to the controller,/hmd ,having trigger /character template, and set your triggers as character trigger so that when it touches it triggers it,,..  triggers are special physics object that only fire out event if any matching template collides or passes through.

[Shanii2]

and considering your erros you might be having issues with selection outline, node. and that your not giving proper input to it, check your units properly where u asssigned selection outline nodes

I have the same issue. I have read the solution, but have now clue how to attach a proxy mesh to my controller.

Can anybody help me with that?

I have the HTC Vive btw, but that should not be a problem.

I believe u have'nt learnt much basics, Help docs, is ure friend for now..  ALso to parent link something to another. you have to use  Unit Link node. followed by an offset position and rotation after link node is applied..

Dear shanii,

Thats true. I had a 3 day course from autodesk, but that is way to short to get the basics. Looking forward to the help docs, but could not found this, sorry.

But thanks for the heads up!
