Default script for using 1 invent with another

[Jhumjhum]

Hello Guys!

In my game, I want a default message when you're using 1 inventory item on another. Something like (U can't use item 1 with item 2)

I read the help file & tried to put such a condition in the Unhandled_event. When I test the game, it gives no errors, but just as I open the inv window, select 1 item & click over another, the game crashes with the message "Invalid inventory item specified).

But my default script for using an inventory on a hotspot & using an inventory on an object works just fine.

Here's my script:
--------------------

function unhandled_event (int what, int type) {
string name;
string invent;
GetLocationName(mouse.x,mouse.y,name);

if ((what==1) && (type==4)) //Talk to any hotspot
     DisplaySpeech (EGO, "I don't think the %s can talk",name);
     
    else if ((what==2) && (type==2))//Talk to any object
     DisplaySpeech (EGO, "I don't think talking with the inanimate %s will help. Try looking or interacting with the %s.",name, name);


else if ((what==1) && (type==2))//Use Hotspot
     DisplaySpeech (EGO, "I don't think I can fit the %s inside my pocket",name);

else if ((what==1) && (type==1))//Look at Hotspot
     DisplaySpeech (EGO, "Its not worth looking at the %s",name);

else if ((what==1) && (type==3)) {  
      GetInvName(player.activeinv, invent);
      DisplaySpeech (EGO, "I can't use the %s with the %s",invent, name);//use inventory with hotspot
         }    
           
else if ((what==2) && (type==3)) {  
      GetInvName(player.activeinv, invent);
      DisplaySpeech (EGO, "I can't use the %s with the %s",invent, name);//use inventory with hotspot
         }                
           
else if ((what==5) && (type==3)) {
    GetInvName(player.activeinv ,invent);
       
    DisplaySpeech (EGO, "I can't use the %s with this",invent);//use invent with invent
           
}        
}

Can you tell me just what I'm doing wrong?

DisplaySpeech (EGO, "I can't use the %s with this %s",invent,name);//use invent with name

Above workaround seemed to work for me. I'm still using ags 255.

Hello!
I'm having the problem ONLY when I try to use 1 inventory item with another inventory item.
Using an invent item with a hotspot or object works fine. The problem is:

else if ((what==5) && (type==3)) {
    GetInvName(player.activeinv ,invent);
       
    DisplaySpeech (EGO, "I can't use the %s with this",invent);//use invent with invent
           
}      

The error comes in the following line:

GetInvName(player.activeinv ,invent);

It says invalid inventory item.

I believe the problem is that there is no such global variable player.activeinv. Instead you should use this: character[CHARID].activeinv.

Are you using the default built-in inventory window, or a custom inventory?

AGS doens't set the player.activeinv variable in the default inventory window, until you exit the window. Thus, the variable is not yet set, so try  game.usedinv  instead:


GetInvName(game.usedinv, invent);


This will be fixed in the next version to make it consistent.

that would explain why I didn't get the error since my inventory screen is not the default.
It's always visible on screen.

Hi again!
My problem got solved after I replaced  

GetInvName(player.activeinv ,invent);
                        with
GetInvName(game.usedinv, invent);

Thanks to all of you who've answered my post. And yes I'm using the built in inventory window.

But I have another question, if I have to use 1 invent item with another, I will be calling the first selected item as "activeinv" how do I refer to the item I clicked on next ?

Say: the player tried to use a key with a note. The description of key is stored in
GetInvName(game.usedinv, invent);
But how'll I refer to the note?

It may be a stupid question but I'm really new in scripting & variables so I don't know. Please tell me.

Thanx again!

It works like a charm now!
