[MX] Mouse Game

ok on my frame I have this

Code:

---

set (mousex, _xmouse);
set (mousey, _ymouse);

---

and on my object I have this

Code:

---

onClipEvent (enterFrame) {
        if (mousex = 29.9 && mousey = 54.2) {
                _root.gotoAndStop(7);
        }
}

---

and when I test it I get this error messsage

Code:

---

**Error** Scene=Scene 1, layer=back, frame=5:Line 2: Left side of assignment operator must be variable or property.
            if ("mousex" = 29.9 && "mousey" = 54.2) {

Total ActionScript Errors: 1          Reported Errors: 1

please help...its a game where you have to keep your mouse in a certain area(picture) and if you rollOut it goes here and if the mouse coordinates are that you go here...I got pretty much everything to work except this

I've been into as3 for some time and I not a sharp as I use to be. mousex is being call from with in a MC(or what not). I believe you need to add _root.mousex to the code.

onClipEvent (enterFrame) {
if (_root.mousex= 29.9 && _root.mousey= 54.2) {
_root.gotoAndStop(7);
}
}

still got the same error

Try removing the quotation marks and change the = to ==

Code:

---

if (mousex == 29.9 && mousey == 54.2) {

---

still got the same error

Try it without the flash 4 syntax:

Code:

---

var mousex = _xmouse; // instead of Set
var mousey = _ymouse; // instead of Set

---

ok so I have the above post and this aprt

Code:

---

if (mousex == 29.9 && mousey == 54.2) {

---

but I'm still getting errors

Have you tried tracing out mousex and mousey to fully ensure your scope is correct?

What are the errors now?

the same as original. And no I havent becuase tracing pops up in the output box and I hate that

oh dear, looks like your flash future will be very slow and painful.

try:

Code:

---

mousex = _xmouse;
mousey = _ymouse;

onEnterFrame = function () {
        if (mousex == 29.9 && mousey == 54.2) {
                _root.gotoAndStop(7);
        }
};

golden rule - DON'T USE CLIP EVENTS!

and why in the world do you need to check a decimal place for a mouse position? i'm not even sure that's possible, mouse is whole pixels, unless the object is scaled maybe.

I couldn't leave it as onEnterFrame...so I changed it and no errors but doesn't go to frame 7

just look at the logic for a second and you'll see that its close to impossible to trigger that behavior.

the mouse's position is stored in some variables at the start of your game. These numbers are never updated. So if the user had his/her mouse at 5,15 at the start of your game, your "if statement" will never be true.

what you need to do is update the mousex and mousey variables in the onEnterFrame function. Then check these numbers in the if statement. You also need to set your numbers to "whole" numbers. The mouse can never be a decimal (unless the object containing the mouse is scaled)

Code:

---

//store some temporary variables

var mousex;
var mousey;

onEnterFrame = function () {
       
        //update the mouse
       
        mousex = _xmouse;
        mousey = _ymouse;       
       
        //check the mouse's coordinates
       
        if (mousex == 30 && mousey == 54) {
               
                _root.gotoAndStop(7);
        }
};

well still didn't work

i should put that in my sig.

huh? I don't get it, I didn't I tried what the person above me said and it didn't work

please post your fla, or trace out the numbers.

maybe an explanation of what you're trying to achieve can help.

ok can't to big. So how would I do trace?

trace("xmouse: " + mousex + " | ymouse: " + mousey);

didn't work...no errors but didn't go to frame 7

A trace cannot effect anything in your work. It just shows you that what your trying to do is working. Other stuff too..... lol. But cant effect your game, gameplay-wise. So you did something else to get that error.

well using trace, and still checking for when mouse x and y hit that point, works and doesn't work. It works in the sense that there are no errors. But it doesn't work as in when your mouse x and y hit that point, nothing happens

Listen Kraxyk, You're checking for the mouse to hit ONE PIXEL rather than the entire area of the green square! :

if (mousex == 30 && mousey == 54)

30,54 is the location of ONE pixel. (And by the way, I personall would put it like this: if ((mousex == 30) && (mousey == 54)), but that's not the issue here really.


Add this immediately before that IF statement:

trace(mousex+","+mousey);

Now Test Movie and watch the output box. It will show your mouse cursor coordinates in real time. See how there is a wide variety of values when the cursor is over the green box?

this is what I did. copy and past in frame 5's actions

Code:

---

//store some temporary variables

stop();
var didHitStart:Boolean = false;
onEnterFrame = function () {
        if (didItHit(start)) {
                didHitStart = true;
        }
        if (didHitStart && didItHit(end)) {
                _root.gotoAndStop(7);
        }
        };
didItHit = function (m:MovieClip) {
        if (m._xmouse<=m._width/2 && m._ymouse<=m._height/2) {
                return true;
        } else {
                return false;
        }
};

I know I made this code a little long, but you put code into MovieClips. I wanted to us the onRollOver but ,you have a on(RollOut) in the black L shaped Movie Clip. This code will allow you to do what your trying to do.

Just delete the code in frame 5 and replace it with what I put above. Remember or start to put all your code in the a Frame not a Movie Clip. I not trying to fix your game I'm just trying to get you past a hump you can't get over. LOL I put "hump".
