Activate text and RTX subtitle UI

[culacant]

We currently have a function to set an activation text implemented as follows:

• UIManager.ShowInteractionText(string ...)
  • called from MainUIScript.SetActivateText(...)
    • called from RGScriptedObject.ACTIVATE(...)
      • called from the black magic that is the game script interpreter.

When facing an interactable object, this text flickers.
I tried using this ShowInteractionText to display NPC dialog subtitles, and it appears for one frame before disappearing. This probably also causes the flickering above.

Issue 1:
Obviously, get rid of the flickering. Dumb fix is to add a 1-frame delay or something, a better fix is highly encouraged.
How to verify: Load a world and run up to a door :D

Issue 2:
When we have a working UI text, might as well make the dialog (RTX) subtitles visible. This should be a new function in UIManager with 2 parameters:

• string text > the string to show
• float duration > time the text should be active in seconds. Could also be an integer with milliseconds to show if that makes things easier.

Suggested signature: UIManager.ShowSubtitle(string text, float duration)

How to verify: Align with me to plumb the new function in the RGScriptedObject functions. Krisandra in the silversmith area has her script working at least up to RTX playback.

Screenshot, "Talk to Erasmo" is the activate text bottom left, "What? What? what-what" is the RTX text, bit above and centered.

sorry about the PSP UI, I dont know how to turn it off :(

I just remembered that i developed this in my test scene "Interaction Tests". I used the PlayerInteractionManager.cs to call ShowInteractionText(). It definitely works perfectly in that scenario.

Does your PlayerInteractionManager have a selected object when you are expecting to see an interaction text?

I was about to say we don't have an interaction manager, but we do and that's what's causing the flickering:
the RGScriptedObject is running a map script, eg:

The ACTIVATE("$exv") line triggers the following calls:
->RGScriptedObject.ACTIVATE(...)
--> MainUIScript.SetActivateText(...)
---> Game.uiManager.ShowInteractionText(...)
Text shows up no problem, however next frame we run into a problem:
The Player unity object has PlayerInteractionManager enabled, which hides the text again since we never set any selected objects:

I do not see an easy way to re-add the selected objects, since all the "selecting" is being done by the map scripts, and it doesnt really unselect things, it just doesnt call the ACTIVATE when the player is out of range.

Brings me back to the dirty fix:

• Add a small delay to MainUIScript.SetActivateText, where it hides the interaction text after 0.1 seconds or something, timer needs to be reset when a new SetActivateText comes in.
  We will need a timer mechanism in here for the subtitles anyways, so its not as ugly as it seems.
• Disable the PlayerInteractionManager on the Player object since we do not use it.
