What did I do wrong here?

[Nine Toes]

1. Can someone tell me if it's possible to add the value of two variables together within the script?

2. I see there are variables, such as @GIx@, and the @SCORE@ variables that can be put into messages and will display your current score, or whatever, but are there such variables that you can use to plug a character's name, or an inventory item's name into a message.

3. One last thing, I declare my globalints/variables in the script header, correct?

[strazer]

(If the variable is smaller than or equal to 10, but greater than or equal to 7, then do this...)

You just combine two conditions (AND expression), like this:

 if ( (variable >= 7) && (variable <= 10)) {
   //code
 }

An OR expression would use || instead of &&

I see there are variables, such as @GIx@, and the @SCORE@

I knew about @SCORE@ and so forth, but where did you read about @GIx@? Didn't know that and I couldn't find it in the manual.

One last thing, I declare my globalints/variables in the script header, correct?

AFAIK the script header covers (all) rooms only, don't know if the variables work in the global script then.
I define my variables in the global script

 int variable;

then I export it at the end of the global script

 export variable;

then import them in the script header

 import int variable;

This way, the variable is available in both global script and in all rooms.

Sure, it's in the manual under "Setting Up The Game".

This is what it reads:
token   replaced by
@INx@  number of inventory item x that the player has
@GIx@  the current value of GlobalInt x (used with SetGlobalInt/GetGlobalInt)

There are those variables, as well as "%s" and a few others I can't quite remember or find.

What about adding the values of two variables?  Do you know anything about that?

Ah yes, thanks.

Don't quite know what you mean. Doesn't

variable3 = variable1 + variable2;

work?

[Nine Toes]

Correct.  I wasn't aware that AGS could do something like that.  I didn't see it in the manual, so I just thought I'd ask.  (but I feel like a dumbshit now... )

Thanks for the help.  

[strazer]

Anytime, pal  

[Nine Toes]

Okay, I've been reading through the manual for about an hour now, and I just can't seem to find exactly what I've done wrong here....

function game_start() {
  // called when the game starts, before the first room is loaded
  SetInvDimensions(49,49);
  int jim_health = 10;
}

function repeatedly_execute() {
  // put anything you want to happen every game cycle here
*  if ((jim_health <= 10) && (jim_health >= 7)){
    AnimateButton (STATUSBAR,0,8,0,2,1);
    AnimateButton (STATUSBAR,1,9,0,2,1);
  }
  if ((jim_health <= 6) && (jim_health >= 4)){
    AnimateButton (STATUSBAR,0,8,1,2,1);
    AnimateButton (STATUSBAR,1,9,1,2,1);
      }
  if ((jim_health <= 3) && (jim_health >= 1)){
    AnimateButton (STATUSBAR,0,8,2,2,1);
    AnimateButton (STATUSBAR,1,9,2,2,1);    
  }
  if (jim_health == 0){
    AnimateButton (STATUSBAR,0,8,3,2,1);
    AnimateButton (STATUSBAR,1,9,3,2,1);
  }
}

The * is where this error message comes up when I test the game:
Error (line 11): undefined symbol 'jim_health'

The writing in bold is the script I'm trying to make work.  I didn't know where to declare my variables, so I just declared them in the same area as SetInvDimensions.

Any ideas?

Put that variable declaration line of jim_health outside of game_start() function, otherwise it will be declared within the function and destroyed when the function ended.

So just put the line:
int jim_health = 10;
ON TOP OF the global script, OUTSIDE any functions, and it should work.

The special codes like @GIx@ and @OVERHOSTPOT@ are largely redundant now. The recommended method is to use StrFormat to include whatever variables you want.

For example,

string buffer;
StrFormat(buffer, "Your name is %s.", character[EGO].name);
SetLabelText(STATUSBAR, 1, buffer);
