moving a mc only with actions

[webzoogirl]

hi all
I'm learning how to use as for moving mc. I've used 'motion using action script' tutorial to move a mc to a x and y value (i just changed some values) but now I'd want my mc to move on the stage between two coordinates: x=20 to x=40 and Y=21 to y=53. So my mc must start with x=20 and y=21, move to x=40 and y=53, and when it reaches this coordinates, I want to put it to the original coordinates (x=20 and y=21) and redo the same movement (to x=40 and y=53) again. How can I do it? please help me, I'm a newbie with as ;-)

thanx

Well, you're going to need variables now. Have u read the variables tutorial yet ? Basically u declare one like this :
_root:variableName = someValue;

So, u could say something like :
_root: originalX = 20;
_root: originalY = 21;
_root:borderX = 40;
_root:borderY = 53;
// PLZ note, there's no space between : and O but was nessecary to prevent smilies)

Next, use if statements to check if u have reached your border :
var currentX = _root.mcThatsMoving._x;
var currentY = _root.mcThatsMoving._y;
// var is a local variable. It's removed from yer memory after its not needed anymore
if (_root.mcThatsMoving._x <= _root:borderX) {
_root.mcThatsMoving._x = _root.mcThatsMoving._x + 2;
} else {
_root.mcThatsMoving._x = _root: originalX;
}

Do the same for the Y, and you're good to go. Do note that its calculted from the registration point (the black cross)

Good luck !

now it works :-)))
I wrote the > or = condition in separate scripts, that's why it didn't work...

thx very muuuuuuuuuuuuuch!

:-D

well (blush blush !) ...
welcome to the forum, webzoogirl !

[webzoogirl]

he he
here I am again! just one thing...

what is the difference between these two ways of setting variables:

_root.namevariable = 10 I've always used this

and

_root:namevariable = 10 this is that one you gave me


???

what is exactly ':' ?

have a nice day ;-)

ehm ... I'm not really sure myself. They both work. But : only works for variables, thus u now its a variable. I believe it depends on yer notation. Using the tidy-code way it makes no difference, but old-style it does (? <- like I said, not sure).:rolleyes:

Ah ... just one ? :p Then u too.

me thinks it's a matter of taste or coding style as well.

i too use the dot to declare variables. i might consider the colon in the future tho to make it more clear that a variable is being declared as opposed to modified. i could see it's benefit.

also, when i declare a local variable, i do not use 'var'... does THAT make any difference? it seems from my working with it that it does not, and again, i am thinking it's a matter of coding preference... but i would just like to make sure.

.:er:.

Like I said. local variables using var are removed from your memory after the code's done. The normal ones remain there.

I have a ton of free scripts that move or movies acording to variables and different math formulas. If you want to try any other ways of doing it, I have downloadables at www.geckoarts.com
hope this helps, frank
