It’s called a hitTest, there is a tutorial here on kirupa that should help you out. I’ll see if I can find it for you.

There you go 🙂
Just change the code where it changes the text to be nextFrame(); and change the movieclips to the instance names of your movieclips (car and finishline)

onClipEvent (enterFrame) {
if (\_root.circle, hitTest(\_root.block)) {
\_root.text = “Collision Detected”;
} else {
\_root.text = “No Collision”;
}
}
thats what it gives me on that turtorial… so do i change it 2…
onClipEvent (enterFrame) {
if (\_root.car, hitTest(\_root.finishline)) {
\_root.nextframe();
??

Thats all i can think of and it isnt working…
onClipEvent (enterFrame) {
if (\_root.car, hitTest(\_root.finishline)) {
actions
}
nextFrame();
} else {
play();

```auto
onClipEvent (enterFrame) {
if (_root.car, hitTest(_root.finishline)) {
_root.nextframe();
} else {
stop();
}
```
it should look something like that.

K… I attached wat you said 2 and now my car wont move…
onClipEvent (enterFrame) {
if (\_root.car, hitTest(\_root.finishline)) {
\_root.nextframe();
} else {
play();
onClipEvent (enterFrame) {
//This code will advance the car forward.
if (Key.isDown(Key.UP)) {
speed += 1;
}
// This will make the car go backwards
if (Key.isDown(Key.DOWN)) {
speed -= 1;
}
//The car will start to slow down after the speed of 25
if (Math.abs(speed)\>25) {
speed \*= .6;
}
// This will change the angle of the car
if (Key.isDown(Key.LEFT)) {
\_rotation -= 15;
}
if (Key.isDown(Key.RIGHT)) {
\_rotation += 15;
}
// This will make the car move
speed _= .98;
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 \*= -.6;
}
that is wat the movieclip car has attached 2 it and now it wont move as i added that hittest stuuff…
these errors keep poping up as i test teh movie
cene=Scene 1, Layer=Layer 2, Frame=1: Line 36: Syntax error.
Scene=Scene 1, Layer=Layer 2, Frame=1: Line 1: Statement block must be terminated by '}'
onClipEvent (enterFrame) {
Scene=Scene 1, Layer=Layer 2, Frame=1: Line 36: Syntax error.
its really getting anooying… plz help…
note \*I put the movieclip finishline on a seperate layer but that wont matter i dun think as long as it has it’s instance name

all little tut:
[size=3]That goes up, must come down.
[size=2]
the same is for font=Courier New,{},[],""
[/font][/size][/size]
end tut
[size=3][size=2][font=Courier New]
[/font][/size][/size]now take a look at you code
```auto
onClipEvent [color=Sienna]([/color]enterFrame[color=Sienna])[/color] [color=Blue]{[/color]
if[color=DarkOrange]([/color]_root.car.hitTest[color=DarkOrchid]([/color]_root.finishline[color=DarkOrchid])[/color][color=DarkOrange])[u]**[color=MediumTurquoise]{[/color]**[/u][/color]
_root.nextframe[color=Lime]()[/color];
[color=MediumTurquoise] }[/color] else [color=Red]{[/color]
play[color=Green]()[/color];
[u]**[color=Red]}[/color]**
**[color=Blue]}[/color]**[/u]
```
bold and underline are things you missed.
