AS3.0 How to get a movieclip to avoid cursor?

hello everyone,

 

i trying recreate simple interactive application movieclip, mybutterfly, avoids cursor, , @ same time restricted within specific boundary set rectangle object. having trouble getting work. there specific process asked follow , appreciate if can point me in right direction, or me out. here specifications , code have far.

 

specifications:

• i need define following variables:
  • to store values: 15,40,285,185 rectangle
  • to store speed of butterfly: 5
  • to store distance, mouse needs butterfly affect it: 20
  • to store direction of movement in x direction. use 1 indicate movement right , -1 move left.
  • to store direction of movement in y direction. use 1 indicate movement downward, , -1 move upward.
• i need add listener detect mouse moves.
• i should define function named avoidme handle behavior of butterfly.
• within function, need to:
  • use if statements determine direction move butterfly both vertically , horizontally , set direction variables accordingly
  • move butterfly multiplying speed , direction variables
  • keep butterfly within boundaries specified rectangle object

 

here code have far:

 

//variable definition

//rectangle boundaries

 

import flash.geom.rectangle;

import flash.ui.mouse;

import flash.events.event;

 

var xlocation:number = 10;

var ylocation:number = 10;

var widthofrect:number = 270;

var heightofrect:number = 170;

 

var rectboundary:rectangle = new rectangle(xlocation, ylocation, widthofrect, heightofrect);

trace(rectboundary)

 

// butterfly speed

var butterflyspeed:number = 5;

 

// mouse distance butterfly

var mousedistance:number = 20;

 

// movement direction

/* need define direction variables here

one x , 1 y. these contain values 1 or -1

i not sure if should use array here or not */

 

 

// avoidme function

 

stage.addeventlistener(event.enter_frame,avoidme);

function avoidme(event:event):void {

 

                    //if butterfly within 20 pixels of mouse

                    //think how determine - involves finding difference

                    //between mousex , butterfly's x position y positions

                    //

 

                    //next check see if mouse on left or right of butterfly

                    //if mouse on left want move butterfly right

                    //otherwise want move left.

                    //to move left need subtract, move right need add

                    //so here direction variables should have declared above come in.

                    //i need set direction variable either 1 or -1

 

                    // need same thing y , set direction variables

 

                    //now using direction variables, need move butterfly multiplying

                    //the direction variables speed , adding result current

                    //position of butterfly followed adding or subtracting speed

 

 

                    //to check see if it's within boundaries, nee compare position of butterfly

                    //with left,right, top , bottom properties of rectangle object

                    //if butterfly out of bounds, need move in. might have offset the

                    //position butterfly's width or height since registration point in middle

                    //of buttefly

 

}

 

help me!!!

why there such restrictions on how this?  school assignment?  problem having interpretting instructions outlined in avoidme function form of code?
