Flash melder fejl.

Jeg er lige for 5 min begyndt på flash, og har så mange problemer med det der "Actionscripts"

Jeg kiggede på eksperten efter nogle fx. spil, fx et skydespil hvor scriptet er:

onClipEvent(load) {
    if (_name eq "bullet") {
        _visible = 0;
        t = 0
        function shoot() {
            if (!t) {
                this.duplicateMovieClip("bull_" add int(_root._xmouse) add "_" add int(_root._ymouse), ++depth);
                t = 3; // change here...
            }
        }
    } else {
        var speed = 15; // change here...
        dist_x = int(_name.split("_")[1]);
        dist_y = int(_name.split("_")[2]);
        var angle = Math.atan2(dist_y-_y,dist_x-_x);
        x_change = speed*Math.cos(angle);
        y_change = speed*Math.sin(angle);
        x_dir = x_change > 0 ? 1 : -1;
        y_dir = y_change > 0 ? 1 : -1;
    }
}
onClipEvent(enterFrame) {
    if (_name eq "bullet") {
        t = (t > 0) ? t-1 : 0;
    } else {
        if (x_dir*_x < x_dir*dist_x && y_dir*_y < y_dir*dist_y) {
            _x += x_change;
            _y += y_change;
        } else {
            this.removeMovieClip();
        }
    }
}

onClipEvent(mouseDown) {
    if (_name eq "bullet")
        shoot();
}



Men i mit "output" panel siger den:

**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 1: Clip events are permitted only for movie clip instances
    onClipEvent(load) {

**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 22: Clip events are permitted only for movie clip instances
    onClipEvent(enterFrame) {

**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 35: Clip events are permitted only for movie clip instances
    onClipEvent(mouseDown) {

**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 3: Type mismatch in assignment statement: found Number where Boolean is required.
            _visible = 0;

Total ActionScript Errors: 4     Reported Errors: 4
