Debugger - Interaction
The interaction tool (enabled by the 
button in the debugger overlay) allows you to change game elements, e.g. move sprites, while the game is still running.
It is highly recommended, however, that you pause the game using VCR's pause button 
before using the interaction tool. You can always resume the game by clicking VCR's play button 
after you are done with the interaction. If the game is not paused during the interaction, objects affected by acceleration, for instance, will continue to move, making your work harder.
Interaction tools
When the interaction is enabled, a toolbar containing a few related tools is displayed on the left side of the screen. Below is a description of each tool.
Pointer
The pointer tool 
allows you to select game elements. In order to use it, simply click elements on the screen:
Currently only elements that extend FlxSprite can be selected (which exclude tiles of a tilemap, for instance). Elements that belong to your selection will be highlighted in red. If you click an empty space, the selection will be discarded.
You can add/remove elements to/from your existing selection by holding CTRL when you click elements. It is also possible to add/remove a group of elements by clicking and dragging the mouse cursor to create a selection area:
If you press the DELETE key when elements are selected, the debugger will invoke the kill() method of each element in that selection. You can also press DELETE while holding SHIFT to invoke the kill() method and additionally remove the elements from memory, i.e. elements will be removed from Flixel's display list.
Mover
The mover tool 
allows you to move game objects that were selected by the pointer tool. In order to use this functionality, select any element(s) using the pointer tool, then pick the mover tool and click-and-drag anywhere on the screen:
The selected elements will follow the movement of the mouse cursor until you release the mouse button.
The mover tool is also activated while the SHIFT key is kept pressed, so you can move selected elements at any time, even when any other tool is active. After performing a selection, hold SHIFT then click-and-drag anywhere on the screen to move the selected element(s):
When you stop pressing SHIFT, the element(s) will stop moving and your previously active tool will become effective again.
Transform
The transform tool 
allows you to resize and rotate a selected game object. In order to use this functionality, select a single element using the pointer tool, then pick the transform tool and click-and-drag any of the markers around the object:
The circular marker at the top-left corner of the selected object can be used to rotate it, while the squared markers can be used to resize it.
