setProperty problems

The script is not realizing the value of "menuh"&(counter) (ex: menuh1 = 14). Any idea why?

This is loaded first:

Quote:

---

// Set up variable to keep track of which menu is being clicked.
menu_num = "0";
menuh1 = "14";
menuh2 = "195";
menuh3 = "245";
stop();

---

This brings the category UP:

Quote:

---

counter = menu_num;
while (Number(counter)<3) {
counter = Number(counter)+1;
setProperty("/menu"&(counter), _y, getProperty ( "/menu"&(counter), _y )-"menuh"&(counter));
}

---

This brings the category DOWN:

Quote:

---

counter = menu_num;
while (Number(counter)<3) {
counter = Number(counter)+1;
setProperty("/menu"&(counter), _y, getProperty ( "/menu"&(counter), _y )+"menuh"&(counter));
}

Seems to be a mixture of Flash 4 and Flash 5 code.

In Flash 5 and higher you dont use the & character to combine variables but the + character.

setProperty("/menu"+counter)

The slash syntax is not recommended anymore and may not be present in future players.

figures...I guess thats what happens when you use an old tutorial.

It still isn't working though:

setProperty("menu"+(counter), _y, getProperty ( "menu"+(counter), _y )+"menuh"+(counter));

Does it know that when I say "menuh"+(counter) I want it to determine which menuh variable it is...say menuh1 and use was it is defined as (in this case 14)... so it would be 14 in place of "menuh"+(counter)

If you want the value of menuh1 variable you have to use eval()

+eval("menuh"+counter)

I don't think I can use eval because I am in MX...

I attached my fla, maybe you can take a look?

eval() is depreciated in MX and was replaced by the array element syntax, thus:

Code:

---

_root["menu"+counter]._y

---

Will work for you (although eval() should still work)

In MX there is no indication of deprecation of eval().

The array object does not evaluate.

For instance, you may have a variable called whatever2.

Then you can have
a=eval("whatever"+i);

to get a to display the value of whatever1.

The array object can not do that to my knowledge.

For arguments sake, I take back the depreciation comment, maybe I was a bit hasty! But, the array object can indeed be used to evaluate:

Code:

---

this.createEmptyMovieClip("holder", 0);
this.holder.lineStyle(1);
this.holder.moveTo(-25, -25);
this.holder.beginFill(0x000000);
this.holder.lineTo(25, -25);
this.holder.lineTo(25, 25);
this.holder.lineTo(-25, 25);
this.holder.lineTo(-25, -25);
this.holder.endFill();
for (i=1; i<=5; i++) {
    holder.duplicateMovieClip("holder"+i, i);
    _root["holder"+i]._y = i*55;
    _root["holder"+i]._alpha = i*20;
}

Try it out and observe the last 2 lines in the for loop affecting the alpha properties and the vertical position of the duped MCs. See? :)

Cheers

But is that an evaluation. Isnt it just putting a string and a variable together to form the name of a movieclip.

I mean.. If you have a variable var1=10;

How would you combine "var"+1 to get the value, if not using eval()

On some further reading it becomes apparant that in Flash 4 and 5, this is legal:

Code:

---

var count = 20;
eval("identifier" + count) = "Dave";
// sets identifier20 to "Dave"
trace(identifier20);

---

But due to the increase in keeping with ECMA-262 specificaction you can't use eval() on the left side of an operator, so in MX, you have to use

Code:

---

var count = 20;
this["identifier" + count] = "Dave";
trace(identifier20);

---

If you try out the first code in MX you'll see that it fails.

Yes I know about leftside assignment and those things. Im curious if you could use my example with the array object.

If I have...

identifier1="dave";

Can you then make "identifier"+count result in "dave" like

// A will here get tha value DAVE
a=eval("identifier"+count);

How would you do it with the array thing?

I have one more question for you experts.

Using the code below, how can I get the links in a target frame (html code)?

I swear this is in another language....

traguardo = new Array(n.length);
traguardof = new Array(fields.length);
inizio = new Array(n.length);
function traguardi() {
cont = 0;
for (i=0; i<n.length; i++) {
nome = "oggetto"+i;
if (i>tasto) {
traguardo[i] = (i+n[tasto])*16+1;
for (a=cont; a<cont+n[i]; a++) {
traguardof[a] = traguardo[i];
}
cont = a;
} else if (i<tasto) {
traguardo[i] = inizio[i];
for (a=cont; a<cont+n[i]; a++) {
traguardof[a] = traguardo[i];
}
cont = a;
} else if (i == tasto) {
traguardo[i] = inizio[i];
for (a=cont; a<cont+n[i]; a++) {
if (a == cont) {
prima = a-1;
}
traguardof[a] = 16*(a-prima)+traguardo[i];
}
cont = a;
}
}
}
clip._visible = 0;
clip1._visible = 0;
cont = 0;
for (i=0; i<n.length; i++) {
nome = "oggetto"+i;
duplicateMovieClip(_root.clip, nome, i+100);
traguardo[i] = i*16+1;
inizio[i] = i*16+1;
_root[nome].tasto = i;
_root[nome]._y = i*16+1;
_root[nome].title = titoli[i];
for (a=cont; a<cont+n[i]; a++) {
nome1 = "oggettonuovo"+a;
duplicateMovieClip(_root.clip1, nome1, a);
traguardof[a] = i*16+1;
_root[nome1].field = a;
_root[nome1].link = links[a];
_root[nome1]._y = traguardo[i];
_root[nome1].title = fields[a];
}
cont = a;
}
function spegni() {
cont = 0;
for (i=0; i<n.length; i++) {
nome = "oggetto"+i;
_root[nome].gotoAndStop(1);
}
spegni1();
}
function spegni1() {
for (i=0; i<fields.length; i++) {
nome = "oggettonuovo"+i;
_root[nome].gotoAndStop(1);
}
}
function chiudi() {
cont = 0;
for (i=0; i<n.length; i++) {
nome = "oggetto"+i;
_root[nome].gotoAndStop(1);
traguardo[i] = inizio[i];
for (a=cont; a<cont+n[i]; a++) {
traguardof[a] = traguardo[i];
nome1 = "oggettonuovo"+a;
_root[nome1].gotoAndStop(1);
}
cont = a;
}
}

Yeah, I've just tried and it seems I can't without using our old friend eval() I was positively certain it could be done though, so I'm sorry for any confusion. I guess it's a lesson learned!

Cheers

(sorry for the thread hijack :))

My idea was that you would add _root[nome1].targer = "mainFrame" here:

duplicateMovieClip(_root.clip1, nome1, a);
traguardof[a] = i*16+1;
_root[nome1].field = a;
_root[nome1].link = links[a];
_root[nome1]._y = traguardo[i];
_root[nome1].title = fields[a];

nevermind...I got it
