syntax question: track an array using variable values

hello everyone ^^

i'm just optimising the dialogs engine in my game, but here's my current problem: for now, i have:

> an array that contains all in-game texts:

Code:

---

dialog = new Array();
dialog[0] = "hello, my name is...";
dialog[1] = "goodbye, i'm leaving.";

---

> now, when a popup window appear, the dialog is called in a dynamic text field:

Code:

---

this.dynamic_text = dialog[1];

---

> you guessed it, "goodbye, i'm leaving" is the text that appears (my actual engine is a bit more complicated, but the idea is the same).

now
imagine that the previous array is named differently:

Code:

---

dialog_pox2_poy4 = new Array();
dialog_pox2_poy4[0] = "hello, my name is...";
dialog_pox2_poy4[1] = "goodbye, i'm leaving.";

---

here are also two variables

Code:

---

popo=2
pipi=4

---

my question
how to call the array "dialog_pox2_poy4" using the variables values? (i mean, how to replace "2" and "4" in the array with the variables)...

> example that is not working, but to show you what i mean:

Code:

---

this.dynamic_text = this["dialog_pox"+popo+"_poy"+pipi+"[1]"];

---

thanks for your answers

this.dynamic_text=dialog_pox2_poy4[popo]

like this?

oh no, not at all ^^

> change the bold part
this.dynamic_text = dialog_pox2_poy4[1];
> using the variables values popo and pipi

Code:

---

popo = 2
pipi = 4

---

Code:

---

eval("dialog_pox"+popo+"poy"+pipi)[0] = value;

---

Blink, didnt you forget "_" infront of "poy"?

eval("dialog_pox"+popo+"_poy"+pipi)[0] = value;

i do believe i did:o

Code:

---

this.dynamic_text = this["dialog_pox"+popo+"_poy"+pipi][1];

---

this should work.
k. ;)

thanks guys, it's working like a charm ^^
