Global/Local variable problem with Dialog

[Bbartram 0]

I have an object, a sign, that has a UserAction which opens a dialog. In this dialog a player can select from a ComboBox any of 5 options. I have a button, CLICK_ME, which I would like to execute a script which will change a marking on the sign based on which option is selected. I have a script, TexSwap.sqs, which uses setObjectTexture to make the change. Obviously I'll need to pass the selection choice to TexSwap.sqs, but for starters I just want to call it with no parameters sent.

I've tested the script TexSwap.sqs when it was directly connected to the UserAction, and it works fine. But now that I'm trying to call it from inside description.ext, I'm having global/local variable problems.

In description.ext:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

class CLICK_ME : RscActiveText

{

idc = 101;

style = ST_CENTER;

x = 0.4;

y = 0.65;

w = 0.2;

h = 0.05;

text = "Click Me!";

action = "[_this select 0] execVM 'TexSwap.sqs'";

default = true;

};

TexSwap.sqs looks like this:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

_ZoneSign = _this select 0

_ZoneSign setObjectTexture [0,"\flextest1\0.pac"]

The error I get when I try this is

Quote[/b] ]

'[_this|#| select 0] execVM 'TexSwap.sqs": Error Local variable in global space

Can somebody please clue me in where I'm going on. Still a beginner at OpFlash scripting.

Thanks,

Brian

Based on that error message, it must be needing 'this' rather than '_this'. (Edit: that's not correct either - see post below)

N.B.: This assumes that ActiveText even has a 'this' parameter for it's actions. Not everything does and those that don't, return random data.

Topic BIKI this shows it to be different for various cases.

setObjectTexture

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_ZoneSign setObjectTexture [0,"\flextest1\0.pac"];

Side topic: I have never got setObjectTexture to work in a normal script. Tried 6 months ago. Is that actually working now? Would love to be using that now.

What object type is _ZoneSign?

Hopefully Dr_Eyeball's diagnosis will fix the issue, however, I have never been able to pass arguments (this, _this, or other types) via a dialog button action code string. I have always had to temporarily make the variables global so they are available in any script and then make them nil once they have been reassigned as local variables in the script called/executed by the dialog button. Please let us know how it works out.

[dr_eyeball 16]

Quick testing seems to indicate ActiveText does not support 'this' or '_this'. So you cannot pass in 'this' or '_this' from an ActiveText since dialogs will only ever deal with dialog controls or properties.

clarify

Looking it at it again, it doesn't quite make sense.

Your post says you are supposed to pass in your "selection", but based on TexSwap.sqs, you are supposed to pass in an "object".

Perhaps you are trying to pass in '_this' from the calling script.

global variable (quick solution)

So like Loyalguard said, it's probably easier to use a global variable in that case.

It all depends. Insufficient info provided to decide.

buttonSetAction (long solution)

Otherwise, you could define the action within the script, not in the class property in description.ext.

Eg: In your script which creates the dialog, you could add:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">buttonSetAction [_idc, format["[%1] execVM 'TexSwap.sqs'", _this select 0]];

However, you cannot pass in objects this way, only ID's and let TexSwap.sqs map the ID to an object via an array or other method.

Thanks for the replies, guys. The global variable fix worked, I added a global called ThisSign. What's the best way to set my global variable back to null? Something like

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">ThisSign = 0?

Is there a way to destroy/deallocate variables?

[loyalguard 15]

I think nil is best.
