Runaway-type cursor? *Finally solved!*

[Bulbapuck]

Hi!
I'm trying to create a game with a 'Runaway' cursor, i.e. a cursor that changes depending on what it's over.
for example: 'talk to' when it's over a character and 'pick up' when it's over an object.
Does anyone know how to do this?

p.s. Is there any way to change the cursor to 'look at' if you press the right mouse button?

In the game's global script there's a function "on_mouse_click", and this is where you'll want to make your changes...

if (button == eMouseRight)
{
  mouse.Mode = whatever mode you need
}

[Akatosh]

For the cursor automatically changing, you could make clever use of the repeatedly_execute function, mouse.x, mouse.y, and Custom Properties.

[Wonkyth]

Thats the way I did it in one of the games I ,made when i was just fooling aroun, and it seemed to work.

[Ghost]

Yes, I use a similar method for my SCUMM ripoff (  ) - basically a custom string to store "look", "get", "use", talk" that is read in repeatedly_execute.

I think you could also create a temporary hotspot/object/character object and check against that, since it's sensible to always talk to a character/examine a hotspot and use an object. If you always want to have the same interactions, you won't need the (more flexible) custom property at all.

Thanks for the quick response !
However, a problem came up.

The cursor seems to be flicking back and forth between the eMode I set it to in repeatedly_execute and the cursor I start with.

Any idea what I should do?

[Ghost]

Put this somewhere on top of your script:

Code: ags

function myUpdateCursor() {
  bool stop;
  stop = false;
  
  if (GetLocationType(mouse.x, mouse.y) == eLocationNothing
  {
      mouse.Mode = eModeWalkto;
      stop = true;
  }
  
  if (!stop && GetLocationType(mouse.x, mouse.y) == eLocationHotspot) 
  {
     mouse.Mode = eModeLookAt;
     stop = true;
  }

  if (!stop && GetLocationType(mouse.x, mouse.y) == eLocationObject) {
    mouse.Mode = eModeInteract;
    stop = true;
  }

  if (!stop && GetLocationType(mouse.x, mouse.y) == eLocationCharacter) {
    mouse.Mode = eModeTalkTo;
    stop = true;
  }
}

Put this in repeatedly_execute:

Code: ags

myUpdateCursor();

And in on_mouse_click you write:

Code: ags

else if (button == eMouseLeft) 
  {
    ProcessClick(mouse.x, mouse.y, mouse.Mode);
    myUpdateCursor(); 
  }

This *should* work...

[Bulbapuck]

Good gravy that was fast!

Thanks Ghost (and Akatosh and wonkyth)
You saved my day

[Bulbapuck]

BUMP!

Okay, I am still using the cursor that you guys helped me with in this thread.

What I'm now trying to do is add an inventory that you don't have to press a button to open, a GUI that is constantly visible (I'm bad at explaining these things) 

But with this cursor I don't know how you can use that inventory since the cursor's eMode is "WalkTo" when it's over the inventory window.

Need help!

Multiple ways:

1) Add another condition to the myUpdateCursor() function, using something like

Code: ags

if (gInventory.GetAtScreenXY(mouse.x, mouse.y) mouse.mode=eModeInteract;

2) You could turn 'Handle inventory clicks in script' to True, and script the interactions yourself. (hence not need it to be in Interact mode)

gInventory.GetAtScreenXY(mouse.x, mouse.y)? I think you might mean:

Code: ags

if (GUI.GetAtScreenXY(mouse.x, mouse.y) == gInventory) mouse.Mode = eModeInteract;

In addition to doing this, I also store a global variable, something like bool walkmode. Then when I check for the inventory I first set the walkmode flag to (mouse.Mode == eModeWalkto). I also add an additional clause:

Code: ags

else if (walkmode) mouse.Mode = eModeWalkto;

[Bulbapuck]

Thanks guys I knew it was something simple all along.

Before I posted here I did infact give the manual a guick glance, and GetAtScreenXY was one of the things I looked at : Guess I was tired or something.

Thanks again Trent and monkey!

[monkey0506]

Glad to hear you got it sorted out. Of course things could even be made simpler if mouse.SaveCursorUntilItLeaves supported inventory items....but that's another story entirely. Best of luck with your game.

[Trent R]

I think you might mean:

Indeed, I forgot it was a static function. Good to hear it worked for you Bulbapuck.

Well, this is embarresing...

I thought it was solved but it wasn't. You see, it was a sort of optical illusion...
The cursor seemed to change to the inventory item but what really happened was that it dissapered

Here's my code:

Code: ags

function repeatedly_execute() 
{
  
 
  if (IsGamePaused() == 1) return;

  if (GetLocationType(mouse.x,mouse.y) == eLocationCharacter && stop == 1 && mouse.Mode != eModeUseinv)
  {
      mouse.Mode = eModeTalkto;
      stop = 3;
  } 
  
  if (GetLocationType(mouse.x,mouse.y) == eLocationHotspot && stop == 1 && mouse.Mode != eModeUseinv)
  {
      mouse.Mode = eModeInteract;
      stop = 0;
  }

  if (GetLocationType(mouse.x,mouse.y) == eLocationObject && stop == 1 && mouse.Mode != eModeUseinv)
  {
      mouse.Mode = eModeInteract;
      stop = 0;
  }

  if (GetLocationType(mouse.x,mouse.y) == eLocationNothing && stop != 1 && mouse.Mode != eModeUseinv)
  {
      mouse.Mode = eModeWalkto;
      stop = 1;
  }
  if (stop!=6)
  {
    if (GUI.GetAtScreenXY(mouse.x, mouse.y) == gGui2 && mouse.Mode != eModeUseinv)
    {
    mouse.Mode = eModeInteract;
    stop = 5;
    }
  }
}

Code: ags

function on_mouse_click(MouseButton button) {
  // called when a mouse button is clicked. button is either LEFT or RIGHT
  if (IsGamePaused() == 1) {
    // Game is paused, so do nothing (ie. don't allow mouse click)
  }
  else if (button == eMouseLeft) {
    if(mouse.Mode==eModeWalkto)
    {
       ProcessClick(mouse.x, yvalue, mouse.Mode );
    }
    else
    {
    ProcessClick(mouse.x, mouse.y, mouse.Mode );
    }
  }
  /*else if (button == eMouseRight || button == eMouseWheelSouth){
    // right-click our mouse-wheel down, so cycle cursor
    mouse.SelectNextMode();
  }*/
    else if (button == eMouseRight && mouse.Mode == eModeUseinv && GetLocationType(mouse.x,mouse.y) == eLocationNothing)
  {
      mouse.Mode = eModeWalkto;
      
  }
  else if (button == eMouseRight && mouse.Mode == eModeUseinv && GetLocationType(mouse.x,mouse.y) == eLocationCharacter)
  {
      mouse.Mode = eModeTalkto;
  }
  else if (button == eMouseRight && mouse.Mode == eModeUseinv)
  {
      mouse.Mode = eModeInteract;
  }      
  else if (button == eMouseRight && stop == 0)
  {
      mouse.Mode=eModeLookat;
      stop = 2;
  }
  else if (button == eMouseRight && stop == 2)
  {
      mouse.Mode=eModeInteract;
      stop = 0;
  }
  else if (button == eMouseRight && stop == 3)
  {
      mouse.Mode=eModeLookat;
      stop = 4;
  }
  else if (button == eMouseRight && stop == 4)
  {
      mouse.Mode=eModeTalkto;
      stop = 3;
  }
  else if (button == eMouseLeft && stop == 5)
  {
    stop = 6;
  }
  
  ...

Sorry for asking again but I just can't seem to figure it out.

Not tested!

Thanks KhrisMUC  Really appreciate your help.

Even though your code didn't quite work it gave me some intresting ideas on how to solve this.

I'll try to solve it myself for now since I need some practice in scripting. I'll update soon!

[Bulbapuck]

I found a solution! 

thank you all so much for your help, I've learned a lot
