# Drag and drop demonstration

This task shows you the drag and drop capabilities of PsychoPy and PsychoJS.
The demonstration uses a drag and drop puzzle game. 
The task requires you to drag and drop the black and white pieces into the empty square.
in order to match the puzzle presented above the empty square. 
When you have finished, press the "Continue" button to see whether or not you were correct, 
and how long the trial took.

To generate more designs, you can run the shapeMaker.psyexp task from Builder.
When you run the shapeMaker task, you will be asked for a number of rows. You 
can choose either 2 or 3 rows for 4 or 9 piece shapes, respectively. Each shape
consists of a grid in the following orders. 

### For 4 piece shapes
| 1 | 2 |
| --| --|
| 3 | 4 |

### For 9 piece shapes
| 1 | 2 | 3 |
| --| --| --|
| 4 | 5 | 6 |
| 7 | 8 | 9 |

The answers for each new shape need to be added the the conditions file, where columns
`a1` to `a9` relate to the shape grid locations as described above. E.g., `a1` relates to space 1
in the grid. So, for an all white shape created using 2 rows (so a 4 piece shape), 
you would enter `"white.png"` in columns `a1` to `a4` in the conditions file, 
and leave the rest of the cells for that row blank.
