hi,

strangely enough, this may be achieved with a simple abstraction, and a minor hack in pd.tk.

The attached MouseState.pd abstraction follows a MouseState interface (Max class). First outlet (mouse button) requires making a few additional changes to pd.tk, 2nd/3rd outlets (x/y position) work in a polling mode only, while 4th/5th outlets (dx/dy) work in a waiting mode only.

To get into it, insert the following line in pdtk_canvas_motion procedure in pd.tk (0.35test-4: before line 976):

pd #mouse motion $x $y ;

and run pd MouseState-test.pd''. Starting Pd without the test patch will also do, if you do not mind watchingno such object'' complaints -- the modified pd.tk requires that a #mouse target exists during an entire Pd session (I have not found any usable target available already in Pd to borrow from).

If transformed into an external, MouseState would not cause such trouble, because it would dynamically modify Tcl definitions and/or bindings. If transformed into an internal, it would behave even better. This is one of the cases, when it is harder to make a prototype, than a real thing.

Btw. I have been catching mouse motion in an external (sic) made as an attempt to emulate Max's assistance feature in Pd. The external itself is working (clumsily), but no way I will soon find the time needed to compile the docs. Expecting major changes to be done to Pd internals, I think the spy project must wait anyway...

I am looking for a way of translating mouse (or touchpad etc) speed to amplitude: the faster the mouse speed, the louder the sound. (The mouse button can be pressed in.)
