[AS3] TypeError: Error #1010 when i try to detect collision

[Rabbel]

Hi, struggling programming student here. I am making a game where you click on people to have them fall and land on a building. I can not get collision detection to work. I have 3 different people with the different instance names but its the same movieclip, they have "states" and i use a switch case break system for their moving(falling) function.

I get the TypeError: Error #1010 when I use this code to detect collision with the building movieclip, the game gets weird and wont work properly.

function DudeMove (dude:MovieClip):void
{

var gravity:Number = 0.08;
switch(dude.State)
{
case CLINGING:

dude.x = Choppah_MC.x+ dude.pos;
dude.y = Choppah_MC.y + ((Choppah_MC.height * 0.5) - 10);

break;

case FALLING:
//dude.addEventListener(MouseEvent.MOUSE_DOWN);


dude.removeEventListener(MouseEvent.MOUSE_DOWN, fall_begin);
//dude.velocity = Choppah_MC.velocity;
//dude.first_fall = false;

if(Choppah_MC.velocity.x > 0) { wind_force.x = -wind_force.x; }



dude.velocity.x += wind_force.x;
dude.velocity.y += wind_force.y;

//Gravity
dude.velocity.y += gravity;

dude.x += dude.velocity.x;
dude.y += dude.velocity.y;

if (dude.target.hitTestObject(building_MC))
{
trace("collision");
}
break;

Ugh. What does the error say after #1010? Errors aren't just obstacles to get around, they are clues as to the nature of the problem.

I Googled your error number, and it's apparently, "A term is undefined and has no properties." So your next step is find out which term is undefined, "dude" "dude.target" or "building_MC" then check the places where you thought you were defining them, etc.
