string comparsion problem

[kellynoky]

Hello there,

I got here a string comparing problem (or I think it is). I try to random generate a number and, say I will drag that number over some other instances, when that number match a instance's name, it will shows "correct"
Now, I got a object instance called a07.

on (release) {
display = substring((Math.random()), 1, 3);
}

Occasionally, display will equal 0.7
Now, with the following coding,

hello = "0." + substring(this._droptarget, 4,1);
// where this.droptarget is the instance a07
if (hello == display) {
_root.green_box.gotoAndStop(2); //Let's say it do stuff A
} else {
_root.green_box.gotoAndStop(3); //Let's sat it do stuff B
_root.a07.gotoAndStop(3);
}

hello should equal 0.7 as well. However, everytime I drag the number over a07, it will do the else part rather than the if part. I must have misunderstand something about the string class...


Could anyone help me here? Thank you very much.

try using some tracing, ex

code:

---

hello = "0." + substring(this._droptarget, 4,1); 

trace(hello);

// where this.droptarget is the instance a07 

if (hello == display) {

trace("yes it equals display");

_root.green_box.gotoAndStop(2); //Let's say it do stuff A

} else {

_root.green_box.gotoAndStop(3); //Let's sat it do stuff B

_root.a07.gotoAndStop(3);

trace("oh no, it doesnt equal display");

}

---

see if it's actually running that or if theres some problem
oh, and use the [/as] [as] tags for code (i put them in wrong order so they dont work

Hello there,

Thanks for the advice. I tried the trace line, and it ends up the display has NOTHING in it...empty string..... but it appear on screen all right. I have look at my display variable, which is a single line dynamic text. I wonder if this is the problem, something like local variable which can't be use outside the function. I was looking at the ActionScript manual, whcih said you can use either setVariables action or (=) assignment to set a gobal variable, which I already did

code:

---

on (release) {

	display = substring((Math.random()), 1, 3);

}

Am I doing something wrong?
