Scripts (new question at bottom)

[shaungaryevans]

Hi,

My game at the moment in samll so all the coding is on the rooms and the global scrpits. The gobal scprit is filling up but I want to build a large game but the gobal scrpit will get too full and it will be very hard finding what I want. I know you can make more scripts but if you made a scipt called 'Misson 2'. how would you go about linking a GUI (which is for 'Mission 2') to the 'Mission 2' script please?

Do you have the link the GUI to the 'Mission 2' script through the global script?

Thank you in advance

Straight from the *manual*:

The main global script still has to contain all the event functions (Look At Character scripts, Interact With Inventory scripts and so forth) and all the GUI handlers (btnSave_Click, etc).
But if you have any custom functions then you can put them in a separate script in order to divide up your code.

So you can move any selfmade functions into an additional script to avoid clutter- this will essentially allow you to build a small library you can easily move between projects. And of course you can CALL your selfmade stuff from the GUI code in your global script, just as you said.

How do you link a GUI button to your own script?

[Khris]

Create a script by right clicking the scripts node in the project tree. Make sure it is above the global script (you can right-click a script and select "move up/down").
In there, put the custom function, e.g.

Code: ags

function my_loadbutton_click() {
  ...
}

Import the function in the new script's header to make it available in the other scripts.

Code: ags

import function my_loadbutton_click();

In the global script, inside the button's OnClick, call the function:

Code: ags

function loadbutton_OnClick() {
  my_loadbutton_click();
}

In there, put the custom function, e.g.

Code: ags

function my_loadbutton_click() {
  ...
}

Is this in the global script or the scrpit i made?

[shaungaryevans]

Can you import the function on_key_code with the int keycode

[Ghost]

a) The button's script will be in the GLOBAL SCRIPT. Because it is a GUI function, and GUI functions need to be in the global script. From within the button's script, you can call a selfmade function.

b) function on_key_press(eKeyCode keycode). Part of the global script too, so it's already available to the whole game. Where do you want to import that, and why??

[shaungaryevans]

it alright, i done it now, thanks

[shaungaryevans]

I have tried the new script out and I did it like this,

I put

function doyouwant_1_OnClick(GUI *theGui, MouseButton button){}

in the global script, then I imported this function into the .ash file  of my scrpit. then I put it in my main script (.asc) and then put what a want it to do when i click on it.

Am i doing it right? 

[shaungaryevans]

Want does this mean please...

Error running function 'doyouwant_1_OnClick':
Runtime erroe: wrong number of paeameters to exported function 'doyouwant_1_OnClick' (expected 1, supplied 2)

[Trent R]

You need 2 parameter to called that function. A GUI, and a MouseButton.

But why are you exporting/importing that function into another script? It would make more sense to create a do_you_want function and then call that in the button's OnCliick function, and wherever else it is needed.

Yes, Trent's right. There's really no need for you to import or export stuff into files where it doesn't belong, and won't work.

Look, try it like this.

For examples sake, let's say you want a button that makes the player say a random quote. Each time you press the button, the player will come up with a funky one-liner.

First, create the button.
Second, create the button's OnClick event. This will go into the global script:

Code: ags

btnGuiButton1_onClick(GUIControl *control, MouseButton button)
{
}

You do NOT need to import or export this at all. What you do now is: You write your own function. This can be in the global script or in ANOTHER script file you create. (as Khris explained already, you need to have these OVER the global script)

Let's say it looks like this:

Code: ags

function SayRandomQuote()
{
  int i = Random(3);
  if (i == 0) { player.Say("We all live in a Yellow Submarine!"); }
  else if (i == 1) { player.Say("Hehey... I am the walrus!"); }
  else if (i == 2) { player.Say("Here comes the sun..."); }
  else { player.Say("Strawberry Fields forever!") };
}

And now, in the button's OnClick (in the global script), you call your selfmade function.

Code: ags

btnGuiButton1_onClick(GUIControl *control, MouseButton button)
{
  SayRandomQuote()
}

And that's it. Now each time you click the button, your character will come up with a random Beatles song, called from the function SayRandomQuote.

Think of all these events for Gui elements as "entry points" where you can add a lot of stuff, including functions you wrote yourself.

Hope that clears it up a little.

edit:
Removed incorrect code.

[Lt. Smash]

Code: ags

btnGuiButton1_onClick(GUIControl *control, MouseButton button)
{
  function SayRandomQuote()
}

you may overlook but you call a function only by its name, its parambrackets and a semicolon.
so it should be

Code: ags

btnGuiButton1_onClick(GUIControl *control, MouseButton button)
{
  SayRandomQuote();
}

you may overlook but you call a function only by its name, its parambrackets and a semicolon.

Oh yes. Sorry, I didn't know. I mean, how should I? Duly corrected.
Is parambrackets a word?

[shaungaryevans]

It works now. I was doing it the wrong way round.

Thank you guys (and girls) for all your help.

[Ghost]

Glad it helped.

Where's the girls?

[Lt. Smash]

Oh yes. Sorry, I didn't know. I mean, how should I? Duly corrected.
Is parambrackets a word?

Not directly. I meant the brackets ( ... ) in which you send your parameters to the function.

[Ghost]

Sorry- could be read the harsh way, that wasn't intentional...
