[FMX] Hittest and functions

programming flash
1

I have a problem running a hitTest on a duplicated object - it doesnt work.

Here is what I have so far, all of this code is in the onload of a movie that is just holding my code-
[AS]
//Makes the rocks
function dupRockFunction() {
var chance = Math.round(random(25));
if (chance == 11) {
rockdepth++;
_root.spaceRock = this.duplicateMovieClip("_root.rock"+rockdepth, rockdepth);
_root.spaceRock._y = random(400);
_root.spaceRock._xscale = random(50)+30;
_root.spaceRock._yscale = _root.spaceRock._xscale;
_root.spaceRock._rotation = random(360);
}
//Moves the rocks
function moveRemoveRockFunction() {
//moves clip to left
this._x -= rockSpeed;
//removes clip when off stage
if (this._x<20) {
this.removeMovieClip();
}
if (this.hitTest(_root.ship)) {
trace(“Hello”);
}
}
[/AS]

I call both functions in the enterframe section of the same MC
[AS]
_root.spaceRock.onEnterFrame = moveRemoveRockFunction;
_root.rock.onEnterFrame = dupRockFunction;
[/AS]

Why doesnt that hittest work? if “this” works to move them across the stage why doesnt it also see the contact of the two MCs??

I am new to functions - slowly learning so if you see anything else major I should change please let me know.

Thanks,

… is that moveRemoveRockFunction inside dupRockFunction? is that what you wanted? and where are
_root.spaceRock.onEnterFrame = moveRemoveRockFunction;
_root.rock.onEnterFrame = dupRockFunction;
?
They arent in the onClipEvent(enterframe) are they?
And do you know duplicated clips keep all functions attached?
also in the name part of duplicate movie, you dont need to specify _root. - just the name

At first glance Im having a little trouble seeing the setup of this. a file would be nice :slight_smile:

NO they should not be inside each other - I dont think they are.

and where are
_root.spaceRock.onEnterFrame = moveRemoveRockFunction;
_root.rock.onEnterFrame = dupRockFunction;?
They arent in the onClipEvent(enterframe) are they?

all of the code I pasted is sitting on a MC - the function section is in the onload and the function calling: [AS]
_root.spaceRock.onEnterFrame = moveRemoveRockFunction;
_root.rock.onEnterFrame = dupRockFunction;
[/AS] is in the enterframe section of the same clip - is that bad? I could not get it to work if I stuck it in the first frame of the game scene

And do you know duplicated clips keep all functions attached?
Yes. . . I think so - does my code not reflect that? That is why I expect the hitTest to work - using this. moves the object but it wont see the hitTest.

I need to add: all the code referenced is on the blue circle left of stage. Thanks

this was my problem, senocular, pointed it out but I ignored him becuase everything else worked. I would love it if someone could explain why it dupicates correctly with _root. there but will not do the hitTest correctly?

[AS]_root.spaceRock = this.duplicateMovieClip("_root.rock"+rockdepth, rockdepth);
[/AS]

should be

[AS]_root.spaceRock = this.duplicateMovieClip(“rock”+rockdepth, rockdepth);
[/AS]

no _root in front of “rock”

just sharing!

for function dupRockFunction the closing } is missing, that’s why sen asked about the nesting, 1st } closes the if only…
“_root.rock” or “rock” +rockdepth will be the instance name of the duplicated clip, so it’s not the same…
