question after drag & drop

eric · #1 (**permalink**) 06-05-2004, 02:48 PM

I would like to ask about a question, that is, after we successfully drag and drop a particular object to its dropzone, it there any command that allow us to make the dropped perfectly objects can't be draggable anymore after it drops to the correct zone?

Here is my coding:

Code:

onClipEvent(load){
	origX = this._x;
	origY = this._y;
}
onClipEvent(mouseDown){
	if(this.hitTest(_root._xmouse, _root._ymouse)){
		this.startDrag();
	}
}
onClipEvent(mouseUp){
	if(this.hitTest(_root._xmouse, _root._ymouse)){
		this.stopDrag();
		if(_parent.dropZone1.hitTest(this._x, this._y, true)){
			this._x = _parent.dropZone1._x;
			this._y = _parent.dropZone1._y;
			_root.start_button.total++;
		}else{
			this._x = origX;
			this._y = origY;
		}
	}
}

why wont u introduce a simple variable to state it is already in the drop zone ... eg ::

Code:

onClipEvent(load){
	origX = this._x;
	origY = this._y;
       this.fixed = false; 
}
onClipEvent(mouseDown){
	if(this.hitTest(_root._xmouse, _root._ymouse) && this.fixed == false ){
		this.startDrag();
	}
}
onClipEvent(mouseUp){
	if(this.hitTest(_root._xmouse, _root._ymouse)){
		this.stopDrag();
		if(_parent.dropZone1.hitTest(this._x, this._y, true)){
			this._x = _parent.dropZone1._x;
			this._y = _parent.dropZone1._y;
			this.fixed = true; 
			_root.start_button.total++;
		}else{
			this._x = origX;
			this._y = origY;
		}
	}
}

OR ... just include some constraint on the if statement to drag the object .... eg ::

Code:

onClipEvent(load){
	origX = this._x;
	origY = this._y;
}
onClipEvent(mouseDown){
	if(this.hitTest(_root._xmouse, _root._ymouse)  &&  (this._x != _parent.dropZone1._x && this._y != _parent.dropZone1._y)){
		this.startDrag();
	}
}
onClipEvent(mouseUp){
	if(this.hitTest(_root._xmouse, _root._ymouse)){
		this.stopDrag();
		if(_parent.dropZone1.hitTest(this._x, this._y, true)){
			this._x = _parent.dropZone1._x;
			this._y = _parent.dropZone1._y;
			_root.start_button.total++;
		}else{
			this._x = origX;
			this._y = origY;
		}
	}
}

aku biasa pakai the first method tu, declare variable when the object is dropped.
