Unity UI Limit UI navigation scope

Hi, I got multiple canvases : game, overlay, ui, popups...

I have a problem: I want to add controller support. But the automatic navigation option scope includes all my canvases, so when I use the controller to try to change the selected gameobject, I can select totally unrelevant gameObjects from other canvases.

I want to be able to limit the automatic navigation to a specified depth. If this is not possible, will I be obligated to implement all the UI transitions by hand?

I'm already aware of the solution consisting of using canvas group and making the root canvas group set inactive and set current UI window active at each transition, but this is not what I'm looking for since I want background UI elements to have their original look and color remain even if a popup pops up, and this is not possible with canvas group solution because background UI gets grayed out.

 

You could try the navigation mode "Explicit" ?

 

I could

 

I agree; use Explicit. You may also want to monitor the currently-selected object. If there isn't one, or if it's on the wrong set of selectables, it's possible that the player bumped the mouse and changed the selection. In this case, reselect a valid selectable.

 

met same problem. mode [explicit]'s problem is, how about dynamically generated UI objects? how explicit set them before even instantiated? At its prefab? Then how to explicit them each other? There is none because now in editor and not the game play mode now, so don't know now how much of them will be generated.

 

Are there no sample codes about this manipulation?
