I am trying to figure out the collision physics for a top-down racing game in Flash / AS3. I am currently using the hitTestPoint method for detecting collisions, but I don't know how to apply a decent physics method to bounce a vehicle off of a wall that it hits.
View 2 RepliesI have the values (x, y, xSpeed, ySpeed) of the movieclips (Hero and Badguy)Now, when they collide, how will i calculate how hard the collision is?Obviously weight, acceleration, etc. are out of the question, as it just needs to be based on their speeds.

View 1 RepliesHow can I modify 2d racing game to seem like isometry? Flash + ActionScript3
ScreeShot:: The game is totally in 2d. Car moves like it should and while it drives the ground everything is fine.I've added a grey ramp. Now the car should move like the arrows are showing, creating illusion of a 3d (isometry).
Ramp is divided in 3 sectors
-first,sector to the right (where the car is currently situated);
-second,sector to the left;
-third, sector on top;
Plus I need the car,to jump out from the ramp when the speed is high. I reffer to old scholl game Rock'n'Roll Racing (Blizzard's game for Sega)So the questions are
1) How should I change car's angle and velocities(velocityX and velocityY) when driving on the ramp ?
2) How can I initiate jumping out of the ramp? For example like in Rock'n'Roll racing? or how Blizzards essentially did it?

View 1 RepliesI need help with one of my Flash projects,I'm trying to use gskinners shape based collision detection, but for some reason I cant get it to work, but im pretty new to using classes, so I dont understand the structure too much. Can i get a tutorial on how to use the gskinner class? im using the as2 version.heres the code, bare with me, there's a lot here. in all codes, mc1 is the track outline MC, and mc2 is the car
basicly im making a 2D top down version of WipEout HD Fury, so file structure is something like this (the .fla is called wipeout as3 because i was initialy coding in as3 and never changed the filename).wipeout as3.fla (the flash file containing all the MCs and animations, but only enough coding to import all of the external code files, as well as the VCam and its script)
the code is;
Code: Select all #include RaceControl.as"
the RaceControl.as is used to determine the Car's control scheme, and refers to a physics code called RaceCar.as. i found it on the interwebs, all credit to matt carpenter;
Code: Select all// Race control
// Create key listener[code]........
the Bounce Function is my own work, and is what i want to happen when a collision is detected.now, the movieclip used for the car is my own drawn design, as is the track, and i want to use GSkinner's shape based collision to detect the collisions properly. so far i have the car driving around quite happily but i need it to collide with the walls of the track, rather than drive right through them.
I want to make a 3D Racing game, becuase i only see crappy overhead one's that are tooo simple to make. so I was wondering the best approach on how to do this. i was thinking of make the race track, as a animation then adding events so when arrow key is moved play event act but then how would the bike react at the same time?
View 15 RepliesI'm building a top-view racing game and I'm using the uch published code to calculate my x and y speed:
speedx = Math.sin(rotation1*(Math.PI/180))*speed*-1;
speedy = Math.cos(rotation1*(Math.PI/180))*speed;
My question is, how can I modify this code to give the car more of a rally-style movement whereas it will go sideways as I go around corners?
I am trying to make a racing game with an overhead view looking down. There will be a separate mc for the ground and another separate mc for the players car. How can I do this? O ya and just in case i am thinking the way I did: I tried to "rotate" the ground but when the car moves down the ground it moves away from the registration point, so therefore it rotates non relative to the car i want to make this game in as3.
View 2 RepliesBasically there will be a club and a ball. You can control the power and angle to hit the ball. How do I go about implementing this? Is flash the easiest way to go? I want to implement this as a facebook game. Any game libraries specific to this I can use to quickly implement a basic version? I am comfortable with Java and PHP.
View 1 RepliesI 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.

I wanted to study some physics code lines related to flash actionscript 2.0.Is there anyway to build a model with physics incorporated without a physics engine? By bare actionscript?If yes, can anyone show me a tutorial or an explanation to learn somehting about it, please?
View 0 RepliesI know you can add a var to add grvity and velocity ect. But what are the limits of this?Can i have a ball roll downhill using physics from within flash, without a external physics engine like box 2D.Can i have impulses? Well thats not important just wondering really.What can you do with physics in flash?
View 5 RepliesLike when the ball bounces off of other objects. I've tried "xvel *= 1;" but it does not work well at all and had some glitches.
View 3 RepliesI'm starting with actionscript 2 and I can't figure out how I set a collision mask for enemies and characters. I've got birds that flap their wings but I only want the player to collide with the body, not with the wings, as they take up too much space and it would be unfair.
I tried mc.setMask and other things I found online, but somehow it didn't work, ie: did nothing. I think I don't get the way this works. I thought you'd need like an invisible rectangle that it checks collisions against instead of the actual animation.
in this how can rotate car when it goes to collied with the track side.
package

import flash.display.MovieClip;
import flash.events.Event;[code]............
I'm trying to create a flash shooter game as my first project. But I can't remove the bullets and enemies when they are hit or off-screen.I've searched for a solution on the problem multiple times and copied about 4 of them (plus I've tried my own ideas) but they are not working.The current method of checking for collisions is:[code]How can I remove the enemies and bullets? removeChild and splice?

View 5 RepliesI'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 m under the process to create a platform based game,but stuck in a problem ,its probably concern with x-axis, actually my player stops certain distance before right wall and with left wall too,i tried to reduce the distance but end up in failure,i have attached the concern fla.

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

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.
I want to make a game using physics in Flash, so I stumbled upon Box2D, but i find that hard to use [the basics are simple, but when i see the scripts,so i was wondering if there are easy to use flash physics engines?
View 6 RepliesThere are some open SDK for Flash, that could be done. Rotating photos with physics? Examples of such programs BumTop, ePic, Coloris (no physics). The photo on the plane, it can be moved to the real physics?

View 4 RepliesIntroduction: I think Nape is a relatively new engine so some of you may not know it. It's supposedly faster than box2d and I like that there is decent documentation. Here's the site: [URL] I'm relatively new to programming. I am decent at AS3's basic functionality, but every time I try to implement some kind of engine or framework I can't even seem to get it to work. With Nape I feel I got a little further than before but I still got stuck.
My problem: I'm using Adobe CS5, I managed to import the SWC file like described here. Next I tried to copy the source of one of the demo's like this one and get it to work but I keep getting errors. I made a new class file, copied the demo source to it, and tried to add it to the stage. My stage code basically looks like this:

I've made a character, and used the bone tool to make it move in runtime.This works fine, but now I want to add gravity/physics, so I can throw my character and it lands on the ground like a real ragdoll. How do I do this in actionscript 3 ? And is it possible to do this within the fla (no class file).
View 1 RepliesOkay so I need to make a basic activity (working Flash/as3) that simulates very basic weighing scales. All the objects that go on to the scales are the same weight.
If you imagine the classic weighing scales [URL]..we are dragging/dropping stuff on to the sides and animating accordingly.
I don't want anything fancy, just the maths required to affect the scales according to how many objects are on each side.
What I'm looking for is probably the angle of rotation of the horizontal arm. Any pointers?
