Galaxy variables

[DeForce]

Hello,

I'm trying to write in custom script in galaxy editor, i'm can achieve something from it, but for now, I've no idea how to declare any variable via custom script.

I've tried to read from script,

    // Variable Declarations
    int lv_a;

    // Variable Initialization
    lv_a = 0;

That's from script when I create variable via gui, but if i create variable via custom script like that:

    int lv_b;
    lv_b = 0;

It just gives me syntax error in int lv_b; side.

So, can i create variables via custom script, or it's not implemented?

Thanks for response.

You can. I recommend you try omitting the prefix (lv_) since that might cause problems when it parses it, dunno.

you can only create local variables at the beginning of a function definition. so if you are in a gui trigger, and use the custom script action to create local variables, it will not work since the trigger will automatically put stuff like

if(!runActions){
    return true;
}

at the beginning of the Actions function, before your custom script. You can, however, use custom script to create local variables for gui functions. Personally, I prefer to do everything through custom script so I have complete control over my code.

The custom script trigger object is outside a function, meaning that any variables declaired are globals. Any variable sets have to be run inside a function however you could do this for optimization sake.

int lv_b = 0;

The action block for GUI is mid function, meaning locals can not be declaired.

So, it means that I can't declare variables with custom script action? But if i write triggers with custom script trigger, any variables that I declare, will multiple "a" in various triggers ruin my triggers all over?

But thanks for response.

You can't unless you create an entire custom script section, which you probably should if you want to code Galaxy. Also, multiple local variables in different functions will not cause conflicts (locals are declared inside functions, globals are declared outside of them).

Thanks for response, you've helped me a lot.

A day passed, and I'm learning how to write own triggers via custom script =)
