hi fellas!

so i have this actor on screen with 50 animation frames, starting at zero, stopped, called
"energyTopLeft" and in Create Actor Event i have:

Code: Select all

ChangeAnimationDirection("Event Actor", STOPPED);
animpos=0;

Fine. Now, in a function i do this:

Code: Select all

switch(collide.whichOne)
        {
            case 0: playSound(1); energyTopLeft.animpos++; break;
        }

which works somehow!
The sound (from my other function) is played.
BUT: the animpos won´t change at all, it stays at zero.

So my question is: What am i doing wrong here? Or is this a bug?

Thanks for any help or ideas

Where is that code located?
In some collision event?
Is whichOne an actor variable?

Answer those questions so I can help you.

If it is in a function, I assume you mean global code, and that is your problem. Using actorName.actorVar is messed up in global code. You can access the event actor's variables, but if you want to use any others you have to add a comment with the actor's name in the event. This is a really undesirable fix... but it is the best we have.
Global Code -> function

Code: Select all

void
darkenMenu ()
{
    menu.r=100;
    menu.g=100;
    menu.b=100;
}

If you want that to work when you call it, do this.

Code: Select all

// menu
darkenMenu();

Now if you have multiple actors with vars being set, you can put in more names in the comment before the function call. It is really annoying problem, and the fix makes no sense since comments are supposed to be ignored, but that should fix your problem.

@lcl: Thanks, global code! its a function. and "whichOne" is an actor variable!

@skydereign: Thanks! no THAT is weird! i have to add a comment with the actor´s name i wanna modify?
tried this, still no luck (global code function)

Code: Select all

switch(collide.whichOne)
        {
            case 0:
            // energyTopLeft
            changeEnergyTL();
            break;
        }

and the function:

Code: Select all

void changeEnergyTL ()
{
    energyTopLeft.animpos++;
}

Could it be a problem because i´m running a function from within a function somehow?

i´ve now simply used another method, via the Event Actor variables

Code: Select all

switch(collide.whichOne)
        {
            case 0:
            collide.doEnergy=1;
            break;
        }

and in my energyTopLeft actor´s draw Event:

Code: Select all

if (doEnergy)
{
    doEnergy=0;
    animpos++;
}


The comment has to go in the event code. Comments before functions within functions still need the comment in the event (not global code). Here's an example.
Global Code

Code: Select all

void
funcA ()
{
    actor.r=0;
    actor.g=0;
    actor.b=0;
}

void
funcB ()
{
    funcA();
}

player -> KeyDown (space) -> Script Editor

Code: Select all

// actor
funcB();

Notice the comment is in the event code and not the global code.

ahhh! thanks very much!
