a "set global" or a "Object.GetAtScreenXY" or.....

[Flyman]

I think is complecated!! I used AGS 3.1
The question:
I have a room and in the room a object " a ball" (1) to pick up. I will that the character can pick up the object "ball" (1), only if, after the character give a inventory item (bombom) to a  object "cat" (2), and the cat move in a new position, the character can pick up the object "ball" (1), else the character say "I can't pick up". How can solve??
I've think for a "set global" or a "Object.GetAtScreenXY" or there is aanother command the I know??
My code:
\\ character give inventory item (bombom)  and the object "cat" (2) move to a new position
if (UsedAction (A_USE_INV)){
  if (MovePlayer (301, 95)) {
   FaceDirection (player.ID, DIR_RIGHT);
   Wait (5);
  PlaySound(35);
       character[16].LoseInventory(iInventory14);
   object[1].SetView(52, 0);
while (object[1].Moving) Wait(20);
object[1].Animate(0, 1, eRepeat, eNoBlock);
object[1].Move(360, 80, 1, eBlock, eAnywhere);
object[1].StopAnimating();
object[1].SetView(50, 0);
while (object[1].Moving) Wait(20);
object[1].Animate(0, 1, eRepeat, eNoBlock);

\\character pick up a object " a ball" (1)    "the code  is incomplete"

if (UsedAction (A_PICK_UP)) {
 if (MovePlayer (325,134)){
\\ must I put a "set global" or a "Object.GetAtScreenXY" command??
   FaceDirection (GetPlayerCharacter (), DIR_RIGHT);
   Wait (5);
   AddInventory (10);
   PlaySound (4);
   ObjectOff (0);
   }
   else {
     DisplaySpeech(GetPlayerCharacter(), "I can't pick up.");
 }
}

Open the Global variables pane, then create a new bool variable. Name it "cat_has_bombom" and set its initial value to false.

After you gave the bombom to the cat, use

Code: ags

  cat_has_bombom = true;

When the player tries to pick up the ball:

Code: ags

  if (cat_has_bombom) {
    // player picks up ball here
  }
  else {
    player.Say("I can't pick up the ball.");
  }

(Older versions of AGS used SetGlobalInt() and GetGlobalInt() to do the same thing; best forget about those as quickly as possible )

Also, PLEASE use [code] tags and indent your code properly.

Thanks Chris for your HELP! Very Great!!
I've see that the new version of AGS is great!! (I've study bool variable ).
But there is also something that dosn't work!!
The code work in part....I've set bool and...
At first, when I pick up the ball....not work
After give bombom cat I pick the ball...work
mmmmm....what is wrong??

After Char give the bombom to the cat,  I've used code:

Code:
if (UsedAction (A_USE_INV)){
 if (MovePlayer (301, 95)) {
   FaceDirection (player.ID, DIR_RIGHT);
   Wait (5);
       PlaySound(35);
       character[16].LoseInventory(iInventory14);
      cat_has_bombom = true; \\ here I've just lose inventory item 14 (giving bombom)
    object[1].SetView(52, 0);
while (object[1].Moving) Wait(20);
object[1].Animate(0, 1, eRepeat, eNoBlock);
object[1].Move(360, 80, 1, eBlock, eAnywhere);
object[1].StopAnimating();
object[1].SetView(50, 0);
while (object[1].Moving) Wait(20);
object[1].Animate(0, 1, eRepeat, eNoBlock);  

Char pick up:
if (UsedAction (A_PICK_UP)) {
 if (cat_has_bombom) {
 if (MovePlayer (325,134)){
   FaceDirection (GetPlayerCharacter (), DIR_RIGHT);
   Wait (5);
   AddInventory (10);
   PlaySound (4);
   ObjectOff (0);
   Wait (5);
   player.Say("A ball.");
   }
   else {
     player.Say("I can't pick up the ball.");

So, what doesn't work?

I thought this is what you wanted, the player can't pick up the ball, only after they gave the bombom to the cat.

Here's how you're supposed to code it:

Code: ags

  if (UsedAction(A_PICK_UP)) {

    // always move the player to the ball
    if (MovePlayer(325, 134)) {
      FaceDirection(player.ID, DIR_RIGHT);
      Wait(5);

      if (cat_has_bombom) {
        player.AddInventory(10);
        PlaySound(4);
        oBall.Visible = false;            // you can use a name instead of object[0]
        Wait(5);
        player.Say("A ball.");
      }
      else {
        player.Say("I can't pick up the ball.");
      }
    }
  }
