Buttons can only be activated from specific angles in projects with physics enabled

Summary

In projects with physics enabled, buttons since the latest version now require you to activate them from a specific angle in-game, regardless of their actual settings/orientation.

What Type of Bug are you experiencing?

Devices

Steps to Reproduce

  1. Create a project with physics enabled in project settings

  2. Place a button device with the default mesh and set it to activate something

  3. The button will only activate the other device when you do it at certain angles.

Expected Result

The button should respect it in-editor settings/orientation

Observed Result

The button requires the player to look at a certain, sometimes extreme angle, for it to send an event.

Platform(s)

All

I can confirm we’re having the same issue in a project with physics enabled.

That is so weird

Try disabling any collision on that mesh. Maybe the collision is interfering with the interaction prompt ?

I’ve tried replicating and i cannot so i would guess that mesh has something to do with it ?

Can you try and let us know.

It seems like there are no issue on a basic button without using a custom mesh

I’ve used a button with a mesh too and its fine so again i believe the issue is either the area of collision or the collision preset ?

It seems very inconsistent and doesnt occur in some sessions

Could you give this a try @RandomBread ?

This does work in a test project however its not really a viable workaround in projects where physics are a core part of the experience. HalcyonKnight mentioned on Twitter that this bug has something to do with line traces and the player capsule, which unfortunately we cant access directly

Is this the similar reason why many maps with interactables, be it later in a session or at the start of it, maybe using the button device would have issues? Like with many roguelike maps having sometimes an 50/50 for this, for a while.

Or some interact ables in tycoons be in weird angles, be it hit detection or otherwise.

Thank you, we’ll be sure this gets looked at.
