Mouse bug with an InputMethod.KeyboardOrController;

Hi!

I'm making a "side scroller" kind of game. The game is controlled by a keyboard or controller only, but I have a mouse-related bug.

Game looks like that

When the player character is near the hotspot, the player can press the InteractionA button to interact with the hotspot. But sometimes mouse-related code deselects the hotspot, and I'm not sure why.

The setup for the scene looks like that:

KickStarter.settingsManager.inputMethod = InputMethod.KeyboardOrController;
KickStarter.settingsManager.hotspotDetection = HotspotDetection.PlayerVicinity;
KickStarter.cursorManager.allowMainCursor = false;

I also have a custom interaction script:

void Update() {
        if (Input.GetButtonDown("InteractionA")) {
            Debug.Log("click hotspot");
            var hotspot = KickStarter.playerInteraction.GetActiveHotspot();
            if (hotspot != null) {
                hotspot.RunUseInteraction();
            }
        }
}

The problem is that sometimes I can see a hotspot menu, but the GetActiveHotspot() returns null.

I've investigated the engine code and I've found where exactly problem happens but I'm not sure how to better fix that as I don't want to modify the code directly and complicate updates in the future.

The "problematic" code is in the file PlayerMovement.cs line 86 or something.

if (KickStarter.playerInput.GetMouseState() == MouseState.SingleClick && !KickStarter.playerMenus.IsInteractionMenuOn() && !KickStarter.playerMenus.IsMouseOverMenu() && !KickStarter.playerInteraction.IsMouseOverHotspot())
{
    if (KickStarter.playerInteraction.GetHotspotMovingTo())
    {
        KickStarter.playerInteraction.StopMovingToHotspot();
    }

    KickStarter.playerInteraction.DeselectHotspot(false);
}

It detects the InteractionA keyboard button as a mouse click and then deselect the Hotspot.

Am I doing something wrong? I would appreciate any help

I'd need to look into this properly, but it may be a bug. The first line may need to include a check for the Hotspot detection method.

Try replacing it with:

if (KickStarter.playerInput.GetMouseState () == MouseState.SingleClick && !KickStarter.playerMenus.IsInteractionMenuOn () && !KickStarter.playerMenus.IsMouseOverMenu () && !KickStarter.playerInteraction.IsMouseOverHotspot () && KickStarter.settingsManager.hotspotDetection == HotspotDetection.MouseOver)
