realistic car

[slyerguy]

can anyone tell me how to make a realistic car, a speedometer, and easy to change stats of the vehicle like max speed, handling, and acceleration?

[Pasquale]

wowzers- that's a lot to ask- I say just start learning basic AS tutes

[Nich]

No kidding... Man that's like a couple months worth of content... A speedometer wouln't be too hard, but the rest would be.

[slyerguy]

well i found this tutorial on making a car but it wouldnt work when i used the code.

[slyerguy]

i used the information in that tutorial i found and modified it to this. this works well but when you are accelerating forward, the car doesn't increase speed until you release the up arrow key.


onClipEvent(load){
speed = 0;
maxSpeed = 40;
minSpeed = -20;
}
onClipEvent(enterFrame){
if (Key.isDown(Key.UP)){
speed += 2;
} else {
if ((Key.isDown(Key.DOWN)) and speed >=0){
speed -= 5;
if ((Key.isDown(Key.DOWN)) and speed < 0){
speed -= 1;
} else {
speed *= .9;
}
}
if (speed >= maxSpeed){
speed -= 2;
} else if (speed <= minSpeed){
speed += 1;
}
if (Key.isDown(Key.LEFT)) {
_rotation -= speed;
}
if (Key.isDown(Key.RIGHT)) {
_rotation += speed;
}
x = Math.sin(_rotation*(Math.PI/180))*speed;
y = Math.cos(_rotation*(Math.PI/180))*speed*-1;
if (!_root.move.hitTest(_x+x, _y+y, true)) {
_x += x;
_y += y;
} else {
speed *= -.3;
}
}
}

[slyerguy]

nevermind that last post i forgot to remove the "else {" so now i have a decent car, can anyone help me with the speedometer? i have figured out how to put in upgrades for the car so i won't need help with that anymore either

[nathan99]

Heres one, not the best, not the worst

[slyerguy]

ty that is way better than what i had before

[slyerguy]

does anyone know how to make a tachometer and a gear shift

[Pasquale]

LOL go the graphics.

@slyerguy- if ur jst gonna keep asking for things to be made- its kinda moving more toward a job request. This is kinda turning into a requests forum lol

[slyerguy]

well this is the very last thing i need to know

[Pasquale]

I'd say it's the first ;)

[KIERIOSHIMOTO]

SlyerGuy:: Do some research...

[Pasquale]

:) you can learn anything you want (pretty much) here - at these forums. Look @ source code- and the tutes :)

[vini]

y dont you do some research. May be we can think on those lines and work on it

[InfestedDemon]

well your very lucky to have nathan cut a peice of his brain temorarorly to bring you a flash. he's probs the best flash guy i know. your lucky

[slyerguy]

I have this right now for tachometer but for some reason the gear is always 5 and even when i press the key to lower the gear, it goes to 4 then immediately back to 5 so if someone could help me fix this, it would be greatly appreciated.

My GOD!!! Lol, If I can find a sec later I will look at it for you ;)

[Dancso]

Heres one, not the best, not the worst That's awesome!! Too bad i got mx 6, and not 2004....:( so i cant load the source in mx6. Is there any way to solve this problem?
(Get mx2004 i guess..:/)

I would really need the source, because im making a game, and im in search for a good "car simulator" thingy, so if u could paste in the source, i'd be really happy.:)

EDIT: Pls hurry with the reply, im really goin out of time, i have to complete my game before may19th.:(

[Dancso]

I'd really need the source!
Im doing a game-making competition on Jatekfejlesztes.hu (hungarian site)
If i'm not finished with my game before may 19, they'd think im a loser, who cant even make a good racing game.:(

I CAN make cars move, but those are really.... er... weak. I mean like the Flash MX Car component (or what....)
But it's really un-realistic.

[Joppe]

Um, if its for an competition. Why should we help you.. Cheat? :S

[JoshuaJonah]

Considering Nathan just gave you the code for the entire structure and engine of your game, I would say that is cheaing.

If i was hosting this competition and found that you were getting free code from an old master and copying it line for line, then on top of that, milking all the rest of the components out of people on an advanced actionscript forum, I would disqualify you.:|

[slyerguy]

well i still havent figured out why the gears get stuck so could someone help me plz

[nathan99]

Provide a FLA?

Likewise.

[nathan99]

and yes.. I'm in accordance with the other people.. I think I should enter :D

[TheCanadian]

I have this right now for tachometer but for some reason the gear is always 5 and even when i press the key to lower the gear, it goes to 4 then immediately back to 5 so if someone could help me fix this, it would be greatly appreciated.
Your first problem is that you are using the assignment operator (=) instead of the comparison operator (==) in your if statements.

[Pasquale]

I'm not sure you should help - unless you get full creadit for it guys. I'd hate to see somone ripped off.

[hybrid101]

definitely join, nathan:D
and i know it isn't right to ask for fla's with all the code...especially when joining a comp end entering it:P
it would be worse if you won
oh and if i were you slyerguy, give us your fla. try fto make something first, then let us help when you're stuck

and google (www.google.com) is good

[slyerguy]

first off thanks TheCanadian using == insted of = solved the problem with the gears but now can someone help me figure out how to change the rate of acceleration and also make it so holding down the gear key it will still only change one gear insted of keep changing. if you didnt understand that, the fla might help.

[Mr.Pancake]

that handling and such starts off good i will keep an eye on this thread :)

[slyerguy]

im still in need of some help

[Joppe]

It changes many gears when holding down, what you need help with dude? :/

[slyerguy]

i want it only changing one gear when u press the key even if u press and hold down the key.

[Joppe]

here

[slyerguy]

thanks thats just what i wanted

[biznuge]

Why not just investigate into some basic physics and mathematics. RATE OF CHANGE might be especially helpful to you, as would "torque" and "turning effects"

Here's an oldish idea I haven't got around to finishing off though! might help you with momentum and things.

Car Tilez (http://www.biznuge.co.uk/cargame/)

Cursor keys to control, and space bar for handbrake guys!!!
