x and y coordinates and angle

Hello,

I know this question might sound stupid to most of you guys but it is very necessary for me to know the answer.

How can you get x and y coordinates of an instance? My instance is called "rock". This is what I have tried:

PHP Code:

---

onClipEvent(enterFrame){
    trace(rock.x);
    trace(rock.y);
    } 


---

but it does not work.

Next, how can I make this instance go up by a certain angle?

Thank you very much.

in AS2, it's _x and _y

PHP Code:

---

onClipEvent(enterFrame){ 
    trace(rock._x); 
    trace(rock._y); 
    } 


---

in AS3, it's .x and .y (like you have). however, there is no onClipEvent in AS3, so you must be in AS2.

btw, this is the AS3 board.

Um............thank you for your reply. I am sorry about the board error. But in my output window only the word "undefined" is coming up. And I am using AS2 in Flash CS5. Any idea what I am doing wrong? And can you solve my angle problem too? Thank you.

And I also know that I have had posted this question in the general question forum but now that I have posted it here, please help me.

i answered your question in the first part of my reply.

for AS2, properties have an underscore before the name. your code says "rock.x" - it should be "rock._x" - notice the underscore. i'll repaste the corrected code:

PHP Code:

---

onClipEvent(enterFrame){ 
    trace(rock._x); 
    trace(rock._y); 
    } 


---

for angles, the most simple formula is this:

PHP Code:

---

var TO_RAD = Math.PI/180;
object._x = Math.sin(angle * TO_RAD) * distance;
object._y = Math.cos(angle * TO_RAD) * distance; 


---

so if you wanted rock to be positioned at 100 pixels 45 degrees from 0, 0, you'd use:

PHP Code:

---

var TO_RAD = Math.PI/180;
rock._x = Math.sin(45 * TO_RAD) * 100;
rock._y = Math.cos(45 * TO_RAD) * 100; 


---

note that this very simple method will start at the 6 o'clock position and go CCW.
