Destroy all objects in the render window.

[Gus Gus]

Hello everyone,
I'm working on a very small project on SFML, where I spawn square shapes in the render window using left mouse button. However, I have been trying for days to find a way to assign the R button for basically erase or destroy every object on the render window and start again. basically a restart button , without being forced to close the render window.

I appreciate your help:).

Wouldn't that be as simple as; 0. Detect a RMB down event.  1. clear() the screen (which you should be doing every frame anyway).  2. Clear the container holding the objects you draw every frame.

This is a problem if you are a Lua programmer.
