Drag and Drop

[prock-fife]

Many rpgs need a drag-and-drop functionality, where an image can be “dragged” across the screen by the mouse cursor. This would also be useful for the editor.

The implementor will have to decide where best to implement this feature. There’s even been some discussion of a purely script-based implementation. My guess is it is best implemented directly into the video module.

One constraint is that the code should behave well with Guichan. For example, many of the use cases for this feature will involve clicking a Guichan icon and dragging its image into another Guichan widget.

Other use cases include: clicking an instance on a map and dragging it to another location on the map (editor feature).
