Unity UI Cursor Help

ChrisIceBox

Assign it in the component we're talking about - not Unity UI Cursor.

jamesfootlight

Sorry which component needs to be assigned? I’m unsure. Where do I find the raw image?

jamesfootlight

Done it! My bad! Thanks. So from looking at my animator, how would I then have an animation for pulsing chosen interaction (ie Pick Up which is on left of main cursor)? Thanks

jamesfootlight

Would I still need to do this?

Once the hotspot is clicked I would like for either the clicked interaction icon (use, examine etc) to pulse, and then the cursor to do the close animation.

You can hook into the OnHotspotInteract event to update the Animator when a Hotspot interaction is run. Use Animator an transition with "Has Exit Time" to automatically play another animation once the "pulse" animation has ended.

Can you explain more on how I would implement the Pulse on interaction click?

ChrisIceBox

Your script will invoke a Trigger parameter in your Animator named "Interaction" when clicking on a Hotspot. Use this to transition to your pulse animation, optionally accounting for the "CursorID" parameter if you want to use different animations for Use, Examine etc.

Awesome, ok got thay working, my next question is how do I disable the hotspot until the interaction is complete? or another interaction is chosen? As the problem is that once the hotspot closes, it re-opens again as the cursor is in the hotspot area, any way you think that can rectify this?

Check "Cutscene while moving?" in your Hotspot interaction if you want to prevent interactions while the Player moves to a Hotspot.

To have the cursor react to the game being in cutscene mode, create a new bool parameter named "IsInCutscene", and add this to the Update function:

_animator.SetBool ("IsInCutscene", KickStarter.stateHandler.IsInCutscene ());

You can then use that parameter to prevent the Hotspot icons from showing during cutscenes.

jamesfootlight

Ok, think I almost have it, problem is, as soon as the interaction choice is now chosen the cursor automatically closes and we now lose the pulse. Is there a way to let the pulse anim happen first and then the IsInCutscene parameter to apply?

ChrisIceBox

That's down to how you make use of it in your Animator transitions.

jamesfootlight

Ok thanks, can you offer any clue? Here are screenshots of two versions that I have tried that both don't currently work. (Hotspot - Cutscene while moving is on)

This is no longer an AC issue. If you want animation transitions to occur instantly, however, uncheck "Has Exit Time".

jamesfootlight

Hi, maybe so, but now I have added the line to my script:

_animator.SetBool ("IsInCutscene", KickStarter.stateHandler.IsInCutscene ());

and turned on "Cutscene while moving?" the cursor closes regardless of using the IsInCutscene parameter in my animator?

See video:

jamesfootlight

Are you able to offer any further help on this? Thanks Chris, I've tried all anim options i am aware of, I think the script my just close it regardless of my pulse anim?

Also, when I’m cutscene I’d like the ‘cutscene’ cursor to show but after the chosen interaction has pulsed and cursor closed… it’s all quite complex!

Thanks

ChrisIceBox

Aside from displaying the inventory graphic when an item is selected, the script only affects Animator parameter values. How these are used are down to your Animator's transitions - AC is not involved.

As all of your transitions stem from the "Any State" state, however, they will always trigger regardless of which animation is currently playing. If you want certain transitions to only occur while specific animations are playing, you must rely on transitions between those specific states rather than from "Any State".

jamesfootlight

Ok thanks Chris, am setting up animator without Any State set up, not getting there yet for what I want but I will persist, can you let me know which of these parameters I do not need based on my script and AC's set up?

Also Chris, how would I make my cursor holding an inventory object pulse on interaction? Thanks!

ChrisIceBox

can you let me know which of these parameters I do not need based on my script and AC's set up?

The script requires the presence of UseIconID, HasLookIcon, IsSpeaking, InConversation, Interaction, MenuOverrideID, CursorID, InvID, IsInCutscene parameters.

how would I make my cursor holding an inventory object pulse on interaction?

As in, an outline around the item graphic itself? You would need to rely on the InvID parameter I mentioned, and use animation to control the cursor while an item is selected - rather than disable the animator during this time.

jamesfootlight

It’s more that when the cursor is holding an inventory object and it is used on another hotspot, it pulses (changes in size).

Do you think there is an easier way to do what I’m after? I’m terms of interaction, pulse, close

jamesfootlight

Can a UI cursor still draw from the spritesheet cursor animations in the cursor menu? if so I can just animate the raw image as the parameter cursorID call will pull in the animation? Thus reducing the amount of animations I need in my animator?

ChrisIceBox

You can have a script hook into the OnSetHardwareCursor custom event to update your RawImage component with the cursor graphic assigned in the Cursor Manager - and will work with the animated cursor options.

The provided Unity UI Cursor component uses this technique if you assign its "Raw Image To Control" field. Essentially, it's just a case of:

private void OnSetHardwareCursor (Texture2D texture, Vector2 clickOffset)
{
    if (rawImageToControl)
    {
        rawImageToControl.texture = texture;
        rawImageToControl.enabled = texture != null;
    }
}

When combining this with an Animator, you need to be careful not to have your Animator control the RawImage's texture at the same time - otherwise the two will conflict. If your Animator only affected the size of the RawImage object's RectTransform, you'd be fine.
