I'm Having A Recurring Error That Says "TypeError: Error #2007: Parameter hitTestObject must be non-null.
at flash.display::DisplayObject/_hitTest()
at flash.display::DisplayObject/hitTestObject()
at VideoGameGravityTest_fla::MainTimeline/hitTest()"
This Happens When I Go From Frame 4 To Frame 1, The code for Frame 1 Is:
stop();
import flash.events.Event;
winner.visible = false;
stage.addEventListener(Event.ENTER_FRAME, hitTest)
var counter = 0;
function hitTest(evt: Event)
{
score.text = counter;
ball_mc.x = mouseX;
ball_mc.y = mouseY; {
if (counter > 0){
score5.text = "HIT!"
}
if (counter > 10) {
score2.text = "Nice!"
}
}
if (counter > 100) {
score2.text = ""
score3.text = "Almost Their!"
}
if (counter > 199) {
score.text = ""
score3.text = ""
score4.text = "Click ->"
john.x = 497
winner.visible = true
score5.visible = false
}
if (ball_mc.hitTestObject(wall_mc)) {
counter += 10
}
}
john.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);
function fl_ClickToGoToAndStopAtFrame(event: MouseEvent): void {
gotoAndStop(4);
john.removeEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);
stage.removeEventListener(Event.ENTER_FRAME, hitTest)
}
And the code for frame 4 is:
stop();
var bobb: int = 0;
count.text = "" + bobb;
ball_mc.x = 2000
uhoh.visible = false
var flyup: Boolean = false;
var flydown: Boolean = false;
var shoot: Boolean = false;
bullet.stop();
boom.stop();
exit3.x = 2000

If you have any ideas on how to fix this let me know
