need help using hit test

[SlaughterDog]

here's teh deal. (im using action script 1).

ive got a wall called blocks20 with this script:

onClipEvent (enterFrame) {
    _y = _y -20;
}

so that makes that wall move up (why up instead of down, i don't know. maybe its because ive got it inside of another movie clip).

and ive got this ball above it that falls. when it hits the wall, i want it to rise up as if the wall is pushing it up.
here's teh script that im using that don't work:

onClipEvent (enterFrame) {
    _y = _y +10;
    if (_root.ball.hitTest(blocks20, true)) {
        _y = _y -20;
    }
}

now it does fall down, but it goes right down past teh wall. as you can see, it must be flawed. i have no clue how to use hitTest right, and maybe there's some other problem too. can you tell me what i should use for that last part?

first off you have'nt provided the instance of the ball, who's _y property will change so it should be like:-

code:

---

onClipEvent (enterFrame) {

    _y = _y +10;

    if (_root.ball.hitTest(blocks20, true)) {

        _root.ball._y = _root.ball._y -20;

    }

}

---

but I'd suggest

code:

---

onClipEvent (enterFrame) {

    _y = _y +10;

    while (_root.ball.hitTest(blocks20, true)) {

        _y -= 1;

    }

}

Oh and subracting from the _y walue makes it go up because _y and _x are counted from the registration point (Usually the top-left corner). They increase as you get further away from the reg point so going down makes _y increase. Therefore, subtracting from _y makes things go upwards.

Hope this helps.

well i can't say that either of those scripts worked. here are some things that i think you should know: the ball and wall are not in the same layer on the timelene. and, i said that blocks20 had the action script on it. it doesnt. it's a movie clip inside of it that does.

here i will give you the FLA. it is how i tried to set it up. please make all the action script changes so that when the ball hits the wall, it stops falling and rides up with the wall.

what i did was save a copy, and then remove all the stuff that makes the filesize huge (music, stuff i didnt use yet, backgrounds, etc)

Hey. The code was very uneven, see inside the blocks 20 mc for the new code, I hope this is what you want.
