IDE :: Collision Detections For Multiple Mc?
Feb 10, 2010
I am trying to create collision detection between mcs without having to write the code 10 times.
I thought this would work but it gives me this error:
TypeError: Error #1034: Type Coercion failed: cannot convert "crisisAnimation" to flash.display.MovieClip.
at ImagineServicesText2_fla::MainTimeline/hitTester()
Code:
var target_mc:Array = new Array();
var numTextBoxes:Number;
target_mc = ["crisisAnimation","eventTextAnimation","mediaRelationsAnimation", "mediaAnimation", "graphicAnimation", "webAnimation", "advertisingAnimation"];
[code]....

Here's the low down of what I have
- a hero in the middle of the screen who follows the mouse
- he can shoot bullets, so there are multiple instances of the BulletClass
- zombies spawn, so there are multiple instances of the ZombieClass
Where is the best place to put my collisions detection code, and how would I even start? I'm new to AS3 so there's no real code to show you, I just need some starting advice.
Would I have to add each name of the bullet and zombie instances into an array and check them against each other in every enterframe? that could get pretty big....

I'm having a problem with a hitTest that I'm not sure how to correct. Long story short, I have a box that is added to the stage and beings to tween down to the bottom. If the user presses the left arrow to catch the object before it leaves the stage, they get 1 point (hooray!).The issue that I'm having is this...multiple instances of the same MC are supposed to be added to the stage by a timer but because of how I've set it up, they all have the same instance name. That leaves me with one of 2 options. I can get the hit test to work, but only 1 instance ever actually shows up or a bunch show up, but the hitTest fails. How can i add multiple instances of the same object, but still be able to determine if one of them is overlapping the box when the user hits the arrow key?[code]

I want to detect collision for several different objects, but want to keep the code as short as possible. whether I can use an array to hold the different movieclips and then detect collision with the entire array, or if I have to create a class and do it that way.

I read the tutorial about Multiple Object Collision Detection. What I want to do is have there be 3 circles and 3 squares. the circles are moving randomly while the squares are stationary. The actionscript would need to be checking to see whenever the moving circles collide with the stationary squares. However, it doesn't seem to be working. I followed the logic of the tutorial pretty closely, by making a separate list for the instance names. Here is the code for the collision detection.

I'm using Flashcs3 in AS2.[code]My character gets stuck in walls and slows down trying to get out, also, hes about 10x faster now. any suggestions? Im working on a flash overhead shooter, multiplayer only. and I need the script to work so there can still be a bullet collision on each wall and not to be able to walk through it.

Okay, here's the rub. I'm making a little maze game. In this maze game, I have walls. They link to a class called Wall.as. In order to collision detect with the player, I do this:
MovieClip(parent).checkCollisonWithPlayer(this);
Where (parent) is a manager logic class. The parent does this
public function checkCollisonWithPlayer(wall:MovieClip)

I'm trying to create a sort of tree diagram such that, if you click on one of the circles, its child circles spread outward with some degree of randomness from the original circle, connected by lines. I have this working, but now what I want to do is make sure that none of the circles collide with each other and none of the lines criss cross. You can see the screenshot for what is currently happening. My code is below. How do I change this code so that it checks for collisions and avoids them? I've read up on flash's hitTestObject command, but that only works in the context one object to another. I want to test for one object contacting any display object.
import com.greensock.TweenMax;
var sw = stage.stageWidth;
var sh = stage.stageHeight;

I am creating a game where I have two separate arrays of objects that I need hitTested with each other. I found an old tutorial in AS2 that I modified to come up with this code:
ActionScript Code:
for (var w:Number = 0;w < enemyLaserArray.length;w++) {
for (var R:Number = 0;R < barricade1Array.length-1;R++) {
if (enemyLaserArray[w].hitTestObject(barricade1Array[R])) {
[code]....
This code executes like I believe it should, but along with removing the two objects, and splicing them from their arrays, I get this error
Code:
TypeError: Error #1010: A term is undefined and has no properties.on the line hitTestObject line. I have had similar problems in other areas of my project, but this time no matter what I try using trace statements I cannot fathom quite what the problem is.

so I have a function on the Main Timeline that creates an instance of the class Ball once every 60 frames (1 second). In the class code for Ball I have this:
Code:
package {
import flash.display.MovieClip;
import flash.events.*;
[Code].....
As you can see, I am trying to make it so that if two instances of the class Ball collide, then it should output "STOP". But it isn't working.

I'm actually working on a multiple collision detection in actionscript 3.0, using pixel collision for a game for my assignment, where an enemy patrols around and searching for the hero. So, i draw a line between the enemy and the hero, to check whether there's some collision happened between those two. if the line colllides with an obstacle such as wall, door, etc. enemy will not be able to see the hero. When i tried a single line collision with a wall (one object only) it works perfectly.
But here's the problem. For the multiple objects collision (several walls and doors included), i added those objects in an arraylist, When i used for loop to check the collision between the line and those objects in the arraylist, none seems to react , except the first object in the arraylist or index 0.
Is there any simpler way to do the multiple collision detection?

I'm having a problem with my multiple collision detection code for a platformer game.. It checks for collisions on all objects separately and it checks only one object per frame. I need to make somekind of a loop so that it would check every object in one frame. Anyone got an idea? It's coded like this:

I worked on a new Flash project, but I cant seem to find a good solution for how I want my objects to collide. In my project I have: a Ball(moving object) and a Floor(not moving).
The ball is positioned over the floor and drops onto the floor through the gravity that is applied with the code.
[Code]...
Is there a way to have a global gravity in flash AS3. In which you could choose what objects you want to be affected by it? Is there a way to have a block of code that separates moving from still objects and will not let any objects collide(not overlap)?

First: the -23 in the code is what I don't like. Second: every single object that deals with collisions would need to be put into the if statement.Is there a way to have a global gravity in flash AS3.

What kind of code would one need to check for collisions between two symbols? I am hoping to become a game designer so this is important for future references.

I am trying to use boxes for hit collision. I want to be precise with the collision so I was thinking about making multiple small boxes and checking for collision that way. This maybe a stupid idea or a smart one. If I do this way will that affect the performance of the game even though the boxes are invisible and wont be drawn on the stage.
map out the object starting from its center outward. Like right, left, top and bottom. I am creating a flying shooter so the plane has a long wing span. I could also map out the wing span and tail and so on.

suppose I have a set of movieclips on stage. Each movieclips has its own name. I can drag one of these and check when my dragged movieclip collide with the other ones. Is there a way to determine the name of the movieclip that was hit by the dragged one without having to use a for-loop statement and/or array?

I have two particles (mc's) that are linked together to a line. Both particles use xspeed and yspeed when they are moving.
Then to my question.. how will the particles xspeed/yspeed change when the line collide into another movieclip? I know how I can check the collision, but I don't know how I'm going to change the speeds.
I have to use (in the very collision moment);
particle_1's xspeed/yspeed
particle_2's xspeed/yspeed
the lines rotation the direction the line came from the length of the line where on the line it collides

Its been many years since I've used flash and I was just wondering what the easiest way to do collision detection was now. I know that there was some hit test bounding box stuff present earlier but I don't know the capabilities of flash cs4 and the advances that have been made. Google searches have yielded things like complex pixel-perfect collision detection but not a lot seems to have been written about CS4 yet.

I am trying to get some collision detection working. What I have is a ball moving around the stage. There is a box in the middle which when the ball hits, I would like it to bounce off the box. I can get the x axis working fine using hitTestObject but when I detect for collisions on the y axis, the two axis conflict. Does anyone have a way of doing this properly?[code]

I am making a game and it has falling objects (similar to shooting) and it also has some other random generating objects going to the other direction. So the objects aren't already on the stage. I was wondering if when I spawn them if I could put them in an array or something and check collision between the two arrays or what?

With AS3 I managed to resolve the problem I said in the thread, but now I face a new problem.If you hit the wall, it will register a collision as it should. Goes the same for the exit. But if you look to the upper left, there's a rotating rectangle. If you hit the rotating rectangle, it will register a collision IF YOUR CURSOR MOVED.That's right, if you freeze the cursor in place as the rectangle comes sweeping in, it WILL NOT register a collision, meaning if it were a maze game, people could cheat by just staying still.I forgot, here's the code:
Code:
stop();
stage.addEventListener(MouseEvent.MOUSE_MOVE, detectHits);
