Hotspots in a scene UI

jamesfootlight

what's the best way to have scene based hotspots in a scene based UI menu? I am having trouble accessing the hotspots in my current set up. They don't seem to be accessible within my UI.

For a Hotspot to be interactive regardless of where it is placed, it must be placed on the interactive (Default) layer, and given a Collider to be picked up by raycasts.

I am still having trouble with this, please see video:

In my experience, only 3D colliders can be raycasted in UI menus. A Box Collider 2D won't be detected.

You could feasibly switch your game's Camera perspective to 3D while the Menu is open, but it's a bit hacky.

I'd advise against placing Hotspots in your UI.

So I need inventory objects to be used on my ui. As the player needs to unlock the door using inventory objects. How would I go about this? Apart from moving the ui into the scene and using game objects instead of canvas?

It is possible to detect if an item is currently selected when clicking on a UI component by reading the value of AC.KickStarter.runtimeInventory.SelectedItem inside an OnSelect function.
