variables

[KingKong]

how do you use variables in flash and also what is the variable for an objects location? For example: treelocation=20,30 where treelocation is the variable for the location of the tree and it being equal to 20,30 represents where it is.

Hi,

Assigning a variable name and value is simply....

variableName = someValue;

You can use arrays and objects to store lists of information, but for simplicity, assigning a property value to a variable could look something like this.......


myMovieClipX=_root.mcName._x;
myMovieClipY=_root.mcName._y;
_root.mcName.onPress=function(){
startDrag(this);
trace(myMovieClipX);
}

What do I replace what you wrote with variable names and values?

Hi,

Yes, just replace the 'mcName' with the name of your mc and that code will show you the corresponding _x and _y coordinates of the movieclip. The variable being defined is....

myMovieClipX....... given the value '_root.mcName._x'

and

myMovieClipY......... given the value '_root.mcName._y'

Can you give me an example of that code with numbers and actual and names? thanks.

Hi,

The demo code should be pretty easy to understand the way it is. Try creating a movieclip named "box" and paste this onto the first frame of the test movie.....


_root.box.onPress = function() {
startDrag(this);
this.onEnterFrame = function() {
myMovieClipX = _root.box._x;
myMovieClipY = _root.box._y;
trace("My box x position is " + myMovieClipX);
trace("My box y position is " + myMovieClipY);
};
};
_root.box.onRelease = function() {
stopDrag();
};


Assigning values to any variable depends on the project. The demo here uses movieclip properties _x and _y, but variables can contain any data that you need to reference later....

myMoneyVariable = 0;
_root.onMouseDown = function(){
myMoneyVariable+=10;
trace(myMoneyVariable)
}

If myMovieClipX and myMovieClipY = the location of myMovieClip than shouldn't there be a number somewhere after the = sign?

[KingKong]

what's supposed to happen. what was the code supposed to do because I don't think it worked.

The code works correctly. It displays the _x and _y coordinates in the output window.
