Question

Drag and Drop a color?

Asked by: plundquist

Hi! I am working with MX.

I am making a movie where people can try different colors of paint on walls or trim of a room to see what it will look like.

The color "chips" will be on the side, and I want the user to be able to just drag the chip and drop it on the place in the photo where they want to put the color, and the wall or woodwork in the photo will remain that color until they try a different color in that spot.

So far I have the photograph set, and the walls and woodwork are partly transparent. Then I traced the shape of the walls, and the woodwork and made them into movies that are under the right spot in the photo. I have a few color chip buttons up as well. I need the code to know how to do this, or direction to a similar tutorial or something. Thanks so much for your help, and please let me know if you need me to clarify something. Thanks!

Oh, I forgot to say that if it is easier to do, I would also be inclined to use a "click the color, click the spot" approach instead of drag and drop. I am open to suggestions on which is easier/better. Thanks!

I would put a variable in _root that contains the currently selected color and the desired alpha:

var currentColor:Number = 0x000000;
var currentAlpha:Number = 0;

Then I would put onRelease event handlers on the paint chips movieclips like this:

redpainchip.onRelease = function(){
    currentColor = 0xFF0000;
}

Now you just need a wall to "Paint the walls".  If you are publishing the swf for Flash 8 you can use a "Color" filter, otherwise you can use the drawing API in Actionscript:

partOfTheWall.onRelease = function(){
  if(this.wall != undefined) this.wall.destroyMovieClip();
  var wall:MovieClip = this.createEmptyMovieClip("wall",this.getNextHighestDepth(),{_x:0,_y:0});
  wall.beginFill (_root.currentColor, _root.currentAlpha);
  wall.lineStyle (0, 0x000000, 0);
  wall.moveTo (this._x,this._y);
  wall.lineTo (this._x+this._width, this._y);
  wall.lineTo (this._x+this._width, this._y+this._height);
  wall.lineTo (this._x, this._y+this._height);
  wall.endFill();
}

This should get you started - let me know if you need more help!  I need to get my expert status back :D

Thanks so much for your help!! I REALLY appreciate it!
Apparently I am a total novice because part 1 I am not really understanding where to put it.

I think I get part 2, so that is great.

I think I see what is going on in part 3, the only issue for me is that the photos I am using have walls that aren't a perfect rectangle in shape. So I made a movie that is the shape of each wall, and I was hoping that there would be a way to make that shape change color. (I have the photo semi-transparent, and then overlayed over the "wall shape" movies). I REALLY appreciate all of your help, and sorry I am so green at this!! Any "dumbed down" help you could give me would be wonderful:) Thanks!!

When I say _root I mean in the first frame of your timeline, not inside any movieclips.  All the example code I gave above would be in the first frame.  You need to give "instance" names to the movieclips that represent the walls, like "partOfTheWall" so you can refer to it that way in the actionscript, and same for the paint chips that represent the colors the user can choose from.

Part 3 was partially complete but I forgot the most important part.
Right before the last '}' you want to put this code:

// make a copy of the part of the wall and put it above the current one
this.duplicateMovieClip("_root."+this._name+"_2",this.getNextHighestDepth(),{_x:this._x,_y:this._y});
// take the big rectangle of color and "mask" it with the shape of the wall, so the color will be that shape,
// and you will see the color through the alpha of the MC we made above
wall.setMask(this);

I will explain more when I have more time later. Good luck! :D

Thanks so much! I will hopefully get some time later tonight, or tomorrow to give it a try, and I will let you know how I come out. Thank you so much for your expertise!!!
