I'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 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 1 RepliesI 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 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'm creating a drag based control in Flex / Flash, similar to a film strip, where an individual can swipe horizontally to scroll through the items. To make the control feel a bit more natural I've added some inertia to slow the scrolling once a swipe has taken place. When first loaded up there will be five items in view with 'x' numbers of items to scroll through with the 3rd item centred and selected.
My problem though is that I want, when animating, a swipe gesture to determine whether an item will end up the middle (3rd position) and adjust its movement calculation accordingly so it docks with the 3rd / centre position. Imagine you perform a long swipe, it flys pasts 'x' amount of items, but as it slows to a stop it elegantly stops with an item centred / in the 3rd position. To do this I believe I need to determine the distance to travel just from the speed value (as time is irrelevent to the user experience, i.e. a longer / stronger swipe would justify a longer animation skimming through the items).
At the moment I'm invoking the animation routine (with inertia) in the ENTER_FRAME event when the user generates a MOUSE_UP event. When they do this, I obtain the speed of drag (by monitoring this beforehand) and then decrement this speed value on each call of the ENTER_FRAME event until it reaches an appropriate value to stop the animation.
Unfortunately all the speed calculations I've seen deal with Speed and Time to determine distance, I just need Speed. Admittedly, my knowledge isn't strong in this area so I might be missing the obvious.
I am uploading files using the upload() method of the FileReference class. I want to display the current connection speed and I was wondering what was a good way to do that.
My current technique is to use a Timer every 1 mili second such as follows:
var speed:Function = function(event:TimerEvent):void {
speed = Math.round((currentBytes - lastBytes) / 1024);
lastBytes = currentBytes;
}
var speedTimer:Timer = new Timer(1000);
speedTimer.addEventListener(TimerEvent.TIMER, uploadSpeed);
and currentBytes gets set into the ProgressEvent.PROGRESS. This technique seems imprecise. I was wondering what other ways I could use to calculate the upload speed while uploading and display it in real time.
The game is like Asteroids where four rocks are placed in the corners of the stage at the beginning and then start moving randomly around the stage. The problem is the timer used is started the moment that the flash file starts not the moment the player clicks the start button. So if you are on the start screen for 5 seconds before you click play when the game actually begins the rocks are where they would be after 5 seconds of play, which could be right over the player.

I am developing a game for mobile in AIR (as3). I have created some bots for this game that initially just wander around. But when a bonus enters the stage, they have to move to the bonus.The detection of a new bonus and moving of the bots works fine, but there is something wrong with the manipulation when a new bonus enters the stage.Basically, this is how it works (or I try to make it work):My bot moves along with his rotation as a parameter. (works fine)
private function moveToNextLocation():void
{
var angle:Number = _rotation * 0.0174532925; // 1 degree = 0.0174532925 radians
var speedX:Number = Math.sin(angle) * _speed;

I want to add an animated .gif file to my movie. So I created a new symbol and then imported the .gif file to the stage. This created the symbol containing the animated .gif.I dragged the symbol onto the scene where I want it. However, the animation seems to play at a different speed (fps) than normal. So I changed the fps of the symbol (at bottom of Timeline where it says "fps"). But for some reason this changes the fps of the rest of the entire movie.
View 3 RepliesI'm tweening a movieclip from startX to finishX. The value of startX varies but finishX is a constant. But as the startX increases in value the animation appears to be quicker. How do I adjust the speed of the tween to ensure a consistant speed regardless of the value of startX?

View 2 RepliesI have a movie clip on my scene which has a speed applied to it making it move across the screen. This is duplicated when it reaches the other end of the screen.On my scene I have some action script which is acting as a timer. After a set time I want it to increase the speed of the movie clips, making the game become "harder". I seem to be able to manipulate the alpha of my movie clips but can't seem to trigger the speed increase.If i use a setInterval it seems to trigger the speed increase but it does it each time the movie clip is duplicated (so the delay resets, it does not change once and apply throughout)However, where I am changing the alpha I cannot seem to change the speed.

I'm trying to calculate the distance between two images (A and F - there are other images between A and F) but I can't seem to figure out how to do it the right way. The image A.x is "(stage/2) - (A.width/2)" and image F.x is "E.x - imgSpace" which is a negative value (all the images x is of negative value to image A.x). In my oppinion the calculation is F.x - A.x and although it might be right I still ned the value to be non-negative.

I am wracking my brain over how to figure this out and it is REALLY frustrating me. If we have a cannon on a castle wall that shoots a cannonball from (0,0) toward an enemy that sits below on the ground off to the right at (50,-10) and we want the cannonball to always reach 20 units in the air, how do I make a line function where I can plug x in (which will be 0-50) to calculate y out?
y = -a(x - h)^2 + k
is the equation for this where (h,k) is the vertex. This means k will always be 20. I know to keep 'a' negative because that will give an upside down U parabola. But how do I figure out what 'h' and 'a' are? Systems of equations? How on EARTH would I write a function to do that in Actionscript?
