## Realistic Car Movement

The car tutorials I have seen have a good system but just don't hit 'realistic' to me.

This is a modified version of Mathew Dennis' 'Creating realistic car movements' tutorial with a few upgrades. Made in MX but it might work in earlier versions.

First, create the car movie clip.

Insert the folowing code into the clips actions :

``````  onClipEvent (enterFrame) {
//When key UP is pressed, speed is increased
if (Key.isDown(Key.UP)) {
speed += 1;
} else {
//When key DOWN is pressed, speed is decreased
if (Key.isDown(Key.DOWN)) {
speed -= 1;
} else {
//If UP or DOWN aren't pressed then the speed decreases

speed *= .9
}
}
//The car will start to slow down after the speed of 25
if (Math.abs(speed)>25) {
speed *= .6;
}
//Turns the car left
if (Key.isDown(Key.LEFT)) {
_rotation -= speed;
}
//Turns the car right
if (Key.isDown(Key.RIGHT)) {
_rotation += speed;
}
//Moves the car
speed *= .9;
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;
}
}

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
