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:
[Code]...
I have a movieclip called nest, which also contains a movieclip called wall. The bullet is created in the nest movieclip, and I am trying to make the bullet disappear when it hits the wall.The problem is, when the bullet is at B, the hittest succeeds when there is nothing at b. [code]The bullet just passes through the walls.
View 2 Replieshow can I make the collision detection working in my game?I find it really difficult because I have no idea where to start...What I want to do is, when the spaceship hit the asteroid, the game will over (jump to the "end" scene)
View 5 RepliesI have two mc's on the stage, the first one is called missiles and the second one is called boxes. So accordingly I put boxes in the boxes mc and missiles in the missiles mc. My problem is how to detect whether any of the missiles collide with boxes and make damage to the box.
I am using simple and effective algorithm which works but it is very slow when there are many missiles and boxes on stage. I am using two nested "for" cycles which is a bad practice, but I don't have other idea at the moment.
Here is the code
public function onEnterFrame(e:Event) {
for(var i:int=0;i<ground_mc.boxesLayer_mc.numChildren;i++){
mc1=ground_mc.boxesLayer_mc.getChildAt(i);
for(var j:int=0;j<ground_mc.bmLayer_mc.numChildren;j++){
[code].....
Are there other techniques to solve this problem. I have already tried to add detection code in every missile but it is also slow with "for".
ok so I am making a game for a college course and I am having some difficulty getting the collision between my player and the walls to work. Here is my code
Code:
// Collision Wall Test
public function WallTest()
{[code]...........
I'm getting this error every time the function is called
"TypeError: Error #1010: A term is undefined and has no properties.at GamePlay_v01/WallTest()at GamePlay_v01/keyDownFunction()"
I've been at it for hours and cannot figure out for the life of my why its not working. I have set up sentry points around as a perimeter on my character.
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 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.
View 1 RepliesI 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.
View 6 RepliesI 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.
a way, to manage a multiple collision detection with pixel level detection, for objects, not necessarily circles, irregular objects.
View 5 RepliesI have an art based platformer with a movie clip that is basically a triangle shaped object that serves as the slope.My problem is in the collision detection with the slope. Here's the code that i currently have - [code]This basically places the rectangle shape that serves as the main player (_rec) along the slope and increments its y position based on it's current x position. The reg point of the slope is on the bottom left.The problem is that this code comes into effect even if _rec is jumping over the triangle because of the square shaped hitbox of the slope. Also, for the same reason, I cannot jump while on the slope itself.I know of a way to rotate the character based on the incline in the ground but I don't really like that idea. The character should stay vertical at all times. I really don't want to do a tile based version as I have a lot of art already designed, it's only the ground objects that are basic shapes.
View 1 RepliesI'm doing a project at the moment where I am creating a side scrolling platformer in AS3. Currently I have:
-The "Character' which is a ball that can be controlled using the arrow keys and has bounce, friction, gravity etc.
-A scrolling system, the character can move freely within an invisible inner boundary, once the character leaves this boundary the background will scroll to compensate.
The thing I am having issues with is creating collision detection between the "Character" and the "Background.Ground" so that the character can move along the shape of the Ground movieclip within the background movieclip.

I'm in the process of building a platformer with Flash MX using Action Script 2.0, I'm following this tutorial: [URL].. However I'm not following the tutorial, I downloaded the .fla file and followed that. The .fla file available for download functions, but my recreation does not.
I have used all the elements from the tutorial platformer, the scoring counter, the health counter, the pickups, the enemies etc. But it does not work properly.
Here is my attempt for download, can someone please explain where i've gone wrong, and if it's not too much trouble, fix it.
I want to create a platformer game, but there is no tutorials that actually tell you how.What I dont understand is:
- How the level changes when you get to a certain point
- How to do collision with walls
- How to make the player move
I'm making a simple side scrolling platform game called Kit Run. For moving left and right, I have the sprite run in place while the background scrolls in the opposite direction. However, when the sprite jumps straight up and down, the background stays stationary. What I need help with is getting the background to scroll down when the sprite moves up beyond a certain point, and up when the sprite moves down beyond a certain point. Ive tried several probably unnecessarily complicated methods that only sort of work.
View 4 RepliesI'm about to create a scrolling platformer game, something like Gum Drop Hop, where the background is scrolling constantly, and you have to keep running or else you'll die. Do you know any tutorials on how to do something like this? I'm not really sure how I would generate random platforms all the time...

View 5 RepliesIts 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.
View 3 RepliesI 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]
View 4 RepliesSo I've been googling around for information on detecting collisions in AS3 and I found this page which has what troy claims to be a 'pixel-perfect' collision detection algorithm:[URL]..
[Code]...
HitTestObject seems to check collision of bounddaries of shapes, it seems to consider everything rectangular. Also if one object jumps two pixel and other five pixels on EnterFrame it seems like there won't be any hit detection. Seriously guys what else method do you use, if you use hitTestObject how do you use?
View 1 RepliesI'm making small interactive games in flash to learn AS3,I need to check the collision between the player and the wall which is normally simple using the hitTestObject function.But now I made a wall object totally surrounding the player with corridors and turn, a collision playground so to speak. Now when I use the hitTestObject function to check whether the player is in collision with the wall it tells me it always collides supposedly because the player object is within the bounds of the wall object.So assuming that I'm correct about the error:How can I prevent getting a collision when I'm inside the bounds of the wall object but not touching the actual walls in that object?
View 2 RepliesI'm trying to make a game like Mario. I've made a character which can jump right now, but I've got some problems with collision detection.
I would like my character to jump on a bar, which is placed higher. My collision detection doesn't work at all I gues..I've made a cirle which has a instance name mcMain and I've made a MovieClip of it. T also made a rectangle which has a instance name balkje, I also made aMovieClip of it.
I hope you can tell me what is wrong about my code and what I've to change to make the collision detection work!

I have Object "A" that moves around and collides with other objects. There are hundreds of other different objects it can collide with. The only way (I found) to test for collision is to loop through every other object. That seems rather inefficient considering I don't even know how many objects exists. Other objects are constantly created and deleted. So this loop would be rather complicated.Is there a way for object A to receive what other object it collided with so that I can then do some code on that other object. Any way to avoid looping? I later need to find out how to detect what objects are near (within x pixels or so) of object A to decide with which one to interact. Maybe that could also be used now to limit the test of collision? Or maybe it gives someone an idea of what to try?
View 4 RepliesI am in the process of building a project in which several MovieClips "swim" around semi-randomly, and another MovieClip that appears and expands over the mouse on click alters the frequency of the turns. Do do so, I simply need to change the value of a single variable on the first MovieClip's timeline when the two collide. I am using hitTestObject, but I keep running into errors. The expanding MovieClip does not have an instance name, because it only appears when the mouse is clicked, and quickly disappears.
I am receiving the error 1067: Implicit coercion of a value of type Class to an unrelated type flash.display.DisplayObject My code causing my first MovieClip to "swim" is on that MC's timeline, while the rest of the code is on the main timeline.
I have this problem: I am making a game with flash cs5, and i am coding in as3 i have written some code, that spawns an child (a fireball) from the character position. i made a movieclip symbol on my main scene, that mc is the "parent" for all the enemies that i am adding but now i need to detect the collision between an enemy child and a fireball child, does anybody know how to do that? if asked i can post some parts of my code
