"Unblock Me" style of game

Hi. I am trying to make a game similar to the game "Unblock me".

The problem is when i use the "DragDrop" behavior, the object just go through another object. I have tried to use the "Solid" behavior but still the DragDrop seems to ignore the Solid.

I've also tried using the "Physics" property(immovable) but still the result is the same.

Is there any ways to make the dragged objects stop when encountering a solid object??

Here's an example I made a while ago. The basic premise is that it forces the tile to drop from its drag-and-drop if it collides with another block, and realigns it to the grid.

Be sure to pay attention to the collision polygons for the blocks: they're slightly smaller than the images themselves.

GeometriX Awesome example - is it solvable? <img src="smileys/smiley29.gif" border="0" align="middle" />

JohnnySix it sure is. It uses the original layout for this kind of puzzle, which can be solved in a minimum of 81 moves.

It's not easy though ;)

sorry for the late reply but thanks a lot <img src="smileys/smiley1.gif" border="0" align="middle" />
