How can I do something like this?

[Sprite_MC]

Hey, this surely is a newbie question... but here it goes anyway:

I'm trying to make a simple rpg game and I would like to add something like a pop-up text box for the dialog that shows when the character interact with the npcs/items
(like on this game: http://www.mspaintadventures.com/?s=6&p=004692)
but I can't figure out how to do it.
I'm already using a text function that I learned on a tutorial but it isn't exactly what I wanted. I can't even open and close the text with the same key...

onClipEvent (enterFrame) {
    distance = 45;
    ux = _root.char._x;
    uy = _root.char._y;
    hx = this._x;
    hy = this._y;
    if(Math.sqrt((ux-hx)*(ux-hx)+(uy-hy)*(uy-hy))<distance && Key.isDown(Key.SPACE)) {
        _root.TextInstance.text = "text goes here";
    } 
    if (Key.isDown(Key.SHIFT)) {
        _root.TextInstance.text = "";
    }
    
} 

So I would really appreciate some help with this
If someone could link me to a tutorial or whatever that could help it would be awesome

Hope this help.

Create 2 movieclips, one for main character and the other for another character. Name the main character main and the other man.

Create a dynamic textbox on stage and name it instance name statusTxt.

Put this script on your first frame

var xSpeed=4;
var ySpeed=4
main.onEnterFrame=function(){
    radius=8;
      
if(this.hitTest(man)){
    if(Key.isDown(Key.SPACE)){
       statusTxt.text="Save? Yes(Y)  No(N)";
    }
       if(statusTxt.text==""){
       }
       else {
       
        if(Key.isDown (89)){
         statusTxt.text="Saved Successfully.";
       }
      if(Key.isDown(78)){
          statusTxt.text="Remember saving your game later!";
       }
    
    }
}
else {
     statusTxt.text="";
}

    if (Key.isDown(Key.DOWN) &&Key.isDown(Key.UP) ){
        this.ySpeed = 0
        

    }
    else if (Key.isDown(Key.UP)){
        this.ySpeed = -5
        
        this.gotoAndStop("walking");
    }
    else if (Key.isDown(Key.DOWN)){
        this.ySpeed= +5
        
        this.gotoAndStop("walking");
    }
    
    else {
        this.ySpeed=0
    }
    
    if (Key.isDown(Key.LEFT) && Key.isDown(Key.RIGHT)){
    this.xSpeed = 0
    
    
    }
    
    
    
    else if (Key.isDown(Key.RIGHT)){

                this.xSpeed = +5
        this.gotoAndStop("walking");
    }
    
    else if (Key.isDown(Key.LEFT)){
        
        this.xSpeed = -5
        this.gotoAndStop("walking");
    }
    
        
    else {
        
        this.xSpeed =0
    }
    if (this.xSpeed ==0 && this.ySpeed ==0){

    this.gotoAndStop("stand");
    
    }
    
    
    this._x += this.xSpeed;
    this._y += this.ySpeed;
    
    
    while (man.hitTest (this._x, this._y+radius, true)){
this._y--;
this.gotoAndStop("stand");
}
while (man.hitTest (this._x, this._y-radius, true)){
this._y++;
this.gotoAndStop("stand");
}
while (man.hitTest (this._x-radius, this._y, true)){
this._x++;
this.gotoAndStop("stand");
}
while (man.hitTest (this._x+radius, this._y, true)){
this._x--;
this.gotoAndStop("stand");
}
    
    
    
};

Move the character with keyboard arrows, then when close to the man movieclip, hit SPACE aand then Y and N. I can add more things if you want, so it fits what you need.
