Animate Cursor Over GUI Button

[VENOMDRINKER]

I'm trying to script my mouse cursor to animate over GUI buttons and Inventory items like it does over Hotspots.

I understand the Pointers are used somehow but I'm completely new to scripting and have no idea how to get my Cursor to animate in the GUI.

[RootBound]

I would create a global int variable called MouseOverButton which is 0 by default.

Then, in the global script, under repeatedly_execute, put something like this:

Code: ags

if (GUIcontrol.GetAtScreenXY(mouse.x, mouse.y) != null){
  MouseOverButton += 1;
  // if you want it to animate only over certain buttons you'll need to add more conditions to the above if statement 
}

if (Guicontrol.GetAtScreenXY(mouse.x,mouse.y == null){
  MouseOverButton= 0;
  //If mouse animation is repeating, add a line to stop it here
}

if (MouseOverButton == 1){
  //Animate mouse cursor here, non-blocking
}

There might be simpler ways to do this but I'm not at my computer right now. Didn't test it.

Put this somewhere above the repeatedly_execute function in the global script:

Code: ags

int mouseAnimFrame;

function HandleMouseAnim() {
  GUIControl* gc = GUIControl.GetAtScreenXY(mouse.x, mouse.y);
  InventoryItem* ii = InventoryItem.GetAtScreenXY(mouse.x, mouse.y);
  
  if (gc != null && gc.AsButton != null || ii != null) mouseAnimFrame++; // hovering
  else mouseAnimFrame = 0;

  int view = MOUSE_ANIMATION; // view name here
  int frame = (mouseAnimFrame / 5) % Game.GetFrameCountForLoop(view, 0); // speed: 5
  ViewFrame* vf = Game.GetViewFrame(view, 0, frame);
  Mouse.ChangeModeGraphic(Mouse.Mode, vf.Graphic);
}

Now add this line inside the repeatedly_execute function:

Code: ags

  HandleMouseAnim();

I attempted this but didn't get any results.

Put this somewhere above the repeatedly_execute function in the global script:

Code: ags

int mouseAnimFrame;

function HandleMouseAnim() {
  GUIControl* gc = GUIControl.GetAtScreenXY(Mouse.x, Mouse.y);
  InventoryItem* ii = InventoryItem.GetAtScreenXY(Mouse.x, Mouse.y);
  
  if (gc.AsButton != null || ii != null) mouseAnimFrame++; // hovering
  else mouseAnimFrame = 0;

  int view = MOUSE_ANIMATION; // view name here
  int frame = (mouseAnimFrame / 5) % Game.GetFrameCountForLoop(view, 0); // speed: 5
  ViewFrame* vf = Game.GetViewFrame(view, 0, frame);
  Mouse.ChangeModeGraphic(Mouse.Mode, vf.Graphic);
}

Now add this line inside the repeatedly_execute function:

Code: ags

  HandleMouseAnim();

Used this on got a message at the "GUI control* gc = GUIcontrol.GetAtScreenXY(Mouse.x, mouse.y);" line

"Must have an instance of the struct to access a non-static member."

[Khris]

Yeah, I should've listened to my gut and not changed these.

Replace the offending lines with

Code: ags

  GUIControl* gc = GUIControl.GetAtScreenXY(mouse.x, mouse.y);
  InventoryItem* ii = InventoryItem.GetAtScreenXY(mouse.x, mouse.y);

(lower case mouse.x and mouse.y)

Also note that you have to use your own view's name (or number) where it says MOUSE_ANIMATION in my code.

Also please go easy on the quotes, this is really messy to read

Fixed the mouse letter casing.

Now it's telling me "Nested functions not supported (you may have forgotten a closing brace) on the repeatedly_execute() line

[RootBound]

I realized after I posted that the if statements might be in the wrong order. It may also be increasing the variable multiple times per loop, so that it is above 1 before the next line  runs. Apologies for overestimating my own coding skills.

Could be fixable but I am still away from my computer unfortunately.

Khris's code looks like it will give you more precise control over everything anyway.

Nevermind, forgot to end the function with a }

But now when the game starts it crashes saying
"error running function 'repeatedly_execute':
Error (line 107): null pointer referenced"

Line 107 being

Code: ags

 If (gc.AsButton != null || ii != null) mouseAnimFrame++; // hovering

[Khris]

Bah, it was really late

Code: ags

  if (gc != null && gc.AsButton != null || ii != null) mouseAnimFrame++; // hovering

I should have been thinking about time zones before posting 

Changed the line and now my cursor animates over GUI buttons and items!

Something else, now when I select an item and which to the Use Inv cursor it no longer switches to the CursorImage with it's custom hotspot marker but instead stays on the default cursor while the item is selected.
