ActionScript 2.0 :: How To Get Simple HitTest To Work With Two MCs (Lines)
Nov 30, 2009
I am having trouble getting a hitTest to work. My two MCs are lines, one horizontal, one slanted. When the horizontal line gets within the "bounding box" of the slanted line the hitTest is true, but it's not touching the slanted line yet. I saw that the shapeFlag property comes into play here, but only when using coordinates... I'm not sure how to apply it to these two lines. I want the hitTest to be true only when the lines actually touch. I have attached a simple FLA of the problem.

I've been trying to write a hittest that will work for rounded walls on my RPG. But I've been epic phailing.
Heres my code:
onClipEvent(load){speed=10;
}onClipEvent(enterFrame){if(Key.isDown(Key.UP)){this._y-=speed;this.gotoAndStop(5);
}if(Key.isDown(Key.DOWN)){this._y+=speed;
this.gotoAndStop(6);}
if(Key.isDo wn(Key.RIGHT)){this._x+=speed;this.gotoAndStop(7);
}if(Key.isDown(Key.LEFT)){this._x-=speed;this.gotoAndStop(8);}

I'm having a bit of a problem with my script. I currently have a square that moves across the screen. There is another square on the stage as well. I want the other square to call a hitTest with the first square (that moves), which we'll give an instance of "hero". The hitTest should make the "hero" (or first square) rotation a specific degree (in this case 30) and then move him in a specific direction, either up, or down the y-axis or left or right on the x-axis. This is my current code, attached to my second square.
onClipEvent(enterFrame){
if(this.hitTest(_root.hero)){
_root.hero.rotate += 30;
[code]....

Non-programmer here, struggling with having to now (finally) work in AS3.I've looked around, but can't find something similar (or as simple) as my old AS2 scoring - hitTest method was.Problem 1: my converted AS3 game does not hitTest or score.[code]I have a Dynamic text box on the stage named "scorecounter" which is now displaying "0" when the game plays. This is correct.When the gun (mouse) is clicked, we then tell the "hittest1" MC to play, which will detect hits. All Correct.[code]The hittest1 MC plays, and checks if the "cursor" MC was touching the "bug1", and tells it to animate (splat) All bug detections are listed in the hitTest frame - "bug1" through "bug30", ie. the code below x 30. This Fails - maybe because the hitTest MC lists all 30, and not all bugs are visibile at once, some are hidden until required later in the game?[code]Then on the last frame of the "bug1" MC (frame 10), it tells the score to add one. Also Fails - maybe because of errors above, nothing is being processed now.[code]

I am trying to create a game. My game is birds eye view game and I am trying to get it so my character (instance name hero_mc )can't pass through the buildings(instance name block_mc). I have been looking at tutorials on the web and most of them cover it so that a text appears if you hit the object whereas I want it so my character can't pass through or well is "push back", the one tutorial I found doesn't want to work for me, but it's not giving me any errors so I really don't know what is wrong with it.
Actionscript Code:
hero_mc.addEventListener(Event.ENTER_FRAME, enter_frame); function enter_frame(event:Event):void{if (hero_mc.hitTestObject(block_mc)) { trace("hero _mc is next to block_mc") } else { hero_mc.y += 10 hero_mc.x += 10 } }
My character still passes through the block objects.

I have this very simple .fla file and you use the keys to move the bus around. As it detects the hittests with the other movie clips on the stage it goes to and plays a frame on that mc's movieclip. It all works fine but i dont want the hittest to repeat after it has done it once(on each movie clip) so that as you drive the bus around you reveal the photo. [URL]

Code:
//The Austin Weisgrau (El Nacho)

[Code]....
the character instance is Blob and the background instance is Background. i can't get the hitTest to work with either of those two things in the /* */ and i need to no how i can

For some reason I cannot get my hitTest to work on an mc within an mc within an mc...which is assigned to a variable...
Code:
var miniWin:MovieClip = CAD_mc_mini.zoomControl.miniWin;
trace(miniWin); //returns _level0.CAD_mc_mini.zoomControl.miniWin
var mouseListener: Object = new Object();

I was trying to make it so you had to hold up this ball, and if it touched the block near the bottom of the screen, it would go to the first keyframe. (The menu.) So, I labeled the ball, "ball", and the block, "block". Then, I added this code to the block:
onClipEvent (enterFrame) {
if (ball.hitTest(block)){
gotoAndPlay(1)[code]....
And tested it out. To my dismay, it didn't work at all. I've spent about 30 minutes testing other ways, and I cant seem to make it work.

import flash.display.BitmapData;
import flash.geom.Point;
//
var BitmapA:BitmapData = new BitmapData(550, 400, true, 0x00);
[code]....
This is using the bitmapdata.hittest way to check whether the one bitmap is overlapping the other. Throug pixel-to-pixel detection.But I'm having trouble understanding this line:
Code:
if (BitmapA.hitTest(destPoint, 255, BitmapB, currPoint, 255))
I know that destPoint is the topleft point from which it is determining all opaque pixels. No value is given to destPoint so basically it is checking from 0,0. Having determined all opaque pixels from that bitmap it should compare them with the opaque pixels of the other bitmap. But why does currPoint use the topleft coordinate of its movieclip? Couldn't it just as well use 0,0 too? I mean when determining the opaque pixels of bitmap two it might as well start checking for those from 0,0 as the topleft position as well?

i am making a game where a ninja runs through a course, every thing is running smoothly. EXCEPT hittest will not work, hittest never works on ANY of my projects. I know im doing it right, because ive even tried copying and pasting working ones. Look at the attached fla file to see what im talking about.is it my computer that wont let it work, because the exact codes worked for all of the people on youtube that used it.

I am trying to use the following code to simplify multiple Hittests using an Array, but the code won't work. Can anyone tell me why?

I have this code so that when a spaceship goes through a blackhole it plays the spaceships moveiclip. This works fine on the first part of the code when the user just clicks the start button.However, i have put in a difficulty setting and when you change the difficulty setting the hittest doesn't work anymoreand there are no error messages. I have tried putting the blackHoles array in the difficulty function but nothing changes and i didn't really think this would make a difference as the easy function is already using the blackHoles array outside the difficulty function.

I have about 100 movieclips that scroll across the stage from out of bounds. They are supposed to hit another movieclip both in bounds and out of bounds, but it seems like Flash only detects the hittest when it happens within the frame.
if(_root.sceneclip.reef1.hitTest(this._x+300, this._y+350, true) ){

So I'm doing this project for school and all, and I'm trying to do a htitest on an object. For some reason, it doesn't work. So I tried writing out my own method... Which halff worked, but wasn't as exact as it should've been.
Heres my code (Though I'm pretty sure somethings wrong with my MC, so i'll upload the main .fla file)
Code:
right = true;
left = false;
itemX;
itemY;

Lets say that I got movieclips A,B,C,D in my scene and E,F which only come into scene when A hitTest B and C hitTest D.I was able to make the A+B and C+D hitTest functioning properly. But when E,F came into the scene, I tried to make E to hitTest F to get something else function but they won't work.# note that there is some short animation before E & F come into scene.I am pretty sure all the instance names are named properly.

I have two pieces of code, that won't work together.First: this makes a hitTest on an mc to make it run on rollover:
Code:
onClipEvent (enterFrame) {
if (this.hitTest(_root._xmouse, _root._ymouse, true)) {
if (this._currentframe<this._totalframes) {
nextFrame();
[Code]...
Each work seperately, but they won't together. How do I get around this?

Ok, I am new to Flash and I am using CS3. I just learned about creating lines and choosing their end cap styles and joint style. I created 2 lines that were connected, highlighted both with the selection tool and tried to change the join style to miter. It would not work. I also tried round and bevel but they would not work either. I did this over and over with many different sets of lines, and I could not change the join style. What am I doing wrong?

for some reason the hitTest I have setup in the attached file seems to work in relation with the blue box's that surround objects and not with the actually objects. Anyways I'm pretty sure that it has to do with the border.

I have this little slideshow, it is for practise for my students. It always worked well in as 2.0, 5 slides, and two buttons: back and next.The script in2.0 has: prevFrame and nextFrame in the code and for the exceptions in frame 1, and frame 5 we made a new frame 1 in the actions layer, and coded the back button, gotoAndStop(5); and a new frame 5, and coded the next button: gotoAndStop(1); Works.
Now I put the thing over tot as 3.0: And I can not get it to work properly....the buttons work, but when I am on frame 5, and go back to 4, it will go no further than 4, evenso when I go back to frame 1 from 5, I can not go further up than frame 1.
import flash.events.MouseEvent;
stop();
next_btn.addEventListener(MouseEvent.CLICK, volgendFrame);//next_btn.addEventListener(MouseEvent.CLICK,[code].....

I'm not familiar with AS3 at all.I'm working on a simple 2 minute presentation. For testing purposes, I have a layer named "label" that I am using to set a label called "test" (currently it's on frame 1445)I'm trying to put an action in the timeline, frame 1, that will cause the play head to automatically jump to the "test" label so as I build the presentation and test it, I don't have to sit through the entire thing just to see if my latest animations are working as expected. I'd like to move this "test" label down the timeline as I continue to build new parts of the presentation. I would expect this code to jump the play-head to where ever I put that "test" label..Instead, it either doesn't work at all, or it jumps to some other random spot around frame 160. NO other labels are being used in this presentation (I'm using the FlashEff component plugin for effects, in case that info is necessary)
