Problem with variables (SOLVED)

[Joe]

Hello everyone!

I'm making a game which has a float called 'health' but I've got a problem really difficult to explain.
Let's see:

Code: ags

//Script header
float health= 100.00;

Code: ags

//In global script, at repatedly execute
lblhealth.Text=String.Format("Health=%.0f",health);

This code doesnt work very well, because if I call a function like this in the globel script:

Code: ags

//E.g.:At dialog request
health=health+10.00;

It works, but if I call it from room repeatedly executed. E.g.:

Code: ags

//script for Room: Repeatedly execute
//At attack time
health=health- 10.00;

This one isnt shown in the 'lblhealth'.

Hope you understand.
Thankyou.

Dunno if it's related, but you should never initialize a variable in the script header

Put this at the top of your global script:

float health= 100.00;
export health;

And then, in script header, replace what you had with:

import float health;

See if that helps.

Yeah, thanks a lot, it works perfectly.
I had tried that before, but i had fogotten 'export health;'
Thanks again.

Seems to be the same problem then:

If you define variables in the script header, separate variables are created for the global script and each room script. Changing the variable's value from within a room script thus doesn't affect any of the others.

To create a global variable that you can use outside the global script, you have to define it in the global script, export it and then import it into the script header:

Code: ags

// global script

int catStat;
export catStat;

Code: ags

// main script header

import int catStat;

Hmm...perhaps (and I don't know if this is even reasonable), but maybe AGS could generate a warning if you try to compile with variables defined in script headers that a new copy will be created for each room?

It just seems that this causes a lot of confusion.

[Rui 'Trovatore' Pires]

Oh, I can't think of an instance where variables defined in script headers might be useful... but it might. Hey, you never know.

[strazer]

Yes, but some kind of warning wouldn't be amiss.
