_name of hitTest() clips

[XLax]

I've been trying to find a way to find the _name property of a movie clip a certain other movie clip is collided against but can't. Does anybody know?

If you're using MovieClip.hitTest(TargetMC), you already know the name of MovieClips?

I'm trying to find a way so that instead of telling me if the hitTest is true or false, it tells me what movie clip is colliding with my main movie clip.

1. Workout the area classifies as collision. For example, if a MovieClip is within the area within TargetMovieClip location plus/minus 50px it classifies as collision.

2. Go through all the MovieClips on Stage and check if the location is within the area defined.

If I express above in AS it would be:

[tt]// main timeline
onEnterFrame = function ():Void {
for (var s in this) {
if (typeof (this) == "movieclip") {
if (s != "mcTarget") {
if (this._x>mcTarget._x-50) {
if (this._x<mcTarget._x+50) {
if (this._y>mcTarget._y-50) {
if (this._y<mcTarget._y+50) {
trace(s+" is collided with mcTarget!");
}
}
}
}
}
}
}
};
//[/tt]

I am getting this error message:

// in output window
Symbol=Game, Layer=Play, Frame=1: Line 1: '{' expected
onEnterFrame = function ():Void {

Symbol=Game, Layer=Play, Frame=1: Line 17: Unexpected '}' encountered
};
//

The script is correct.

Are you using AS1? If so remove type declaration ":Void" from onEnterFrame line. Also this is a frame script, do not attach to a MovieClip.

Can you explain what your script is saying line by line?

 

[kennethkawamoto]

//Run this script on every frame refresh

onEnterFrame = function (){

//Go through every object in "this" (_root) using "s" as iterant variable

for (var s in this) {

//Is the iterant object MovieClip?

if (typeof (this) == "movieclip") {

//...and it's not "mcTarget"?

if (s != "mcTarget") {

//...and its xy position is within +/-50px of mcTarget?

if (this._x>mcTarget._x-50) {
if (this._x<mcTarget._x+50) {
if (this._y>mcTarget._y-50) {
if (this._y<mcTarget._y+50) {

//...if so then the iterant is collided with mcTarget!

trace(s+" is collided with mcTarget!");

Kenneth, you're a genius.

 

[kennethkawamoto]

I wouldn't go that far!

Oh one more thing
//
function detectCollision(what) {
for (var s in this) {
if (typeof (this) == "movieclip") {
if (s != what) {
if (this._x>what._x-50) {
if (this._x<what._x+50) {
if (this._y>what._y-50) {
if (this._y<what._y+50) {
trace(s+" is touching");
}
}
}
}
}
}
}
}
onEnterFrame = function () {
detectCollision("player");
};
//
I have that, and it keeps tracing "instance3 is touching"
Do you know why?

 

[kennethkawamoto]

Try:

if (this._x>this[what]._x-50) {

etc...

Totally works.
