Using nextFrame(), prevFrame(), and gotoAndStop() to navigate

actionscript-2

I'm trying to make an easy image galleri (one photo each frame), and then two buttons to navigate right/left. When it gets to the final frame, it jumps back to the first if you click next and vice versa for left.

The problem with the code is that I'm only able to jump back to last frame, and forth to first frame again.

Here's the code.

Left button:

on (release) {
if (_currentframe = 1) {
    gotoAndStop(_totalframes);
} else {
   prevFrame();
}    
}

Right button:

on (release) {      
    if (_currentframe = _totalframes) {
    gotoAndStop(1);
    }
    else
    {   
    nextFrame();
    }
}

Made it work by altering the code a bit.

Left button:

on (release) {
    if (_currentframe > 1) {
        prevFrame();
    } else {
        gotoAndStop(_totalframes);
    }
}

Right

on (release) {
    if (_currentframe < _totalframes) {
        nextFrame();
    }
    else
    {   
        gotoAndStop(1);
    }
}

Anyway, there is no direcy way of deleting objects in AS even though you have a new operator to create one. All objects are garbage collected when there are no strong references of that object. Here are two things that you can do:

When adding event handlers to the button object or whatever, mark them as weak OR set the eventhandlers to NULL when you are through
Though there is no explicit delete in AS you can set the object to null using the var = null syntax to enable the garbage collector to mark it as read y for cleanup.

You probably need to set some state variables for each button first, to keep track of what's been clicked and what hasn't. Something like:

var cakeMixSelected = false;
var waterSelected = false;
var chocolateSelected = false;

When one of these is released, change switch its variable to "true".

Then the if statements in your check should look something like this:

if(waterSelected == true) {
    if(cakeMixSelected == true && chocolateSelected == true) {
        //go to chocolate code here
    } else if (cakeMixSelected == true) {
        //vanilla here
    } else {
        //water only here
    }
} else {
    // no water code here
}
