Hello,

I have a problem, and I'm pretty new to Pure Data so I thought I'd ask it here.
I have absolute numbers that change by moving the mouse (x and y). This works OK.
But I need to output the relative speed at which this number changes, so +12 or -30 and not the absolute pixel position.

Is there an easy way to achieve this?

Kind regards,
Jelte

Sorry to double post!

I have a solution to this already.
I used [trigger float float] cross-connected to a minus object, that got me the first difference.
Actually I have another problem now. The mouse is limited to the boundaries of the screen, and unfortunately I need the numbers to go on "forever", and not stop at the end of my screen.
I thought of using the mouse wheel (that keeps giving data/had no end), but I can't catch that with the [cursor] object...

Does anybody know a solution to that one?

Thanks!
Jelte

I recently discovered the [tot] object from the toxy lib in the help browser.

Give it the name of a patch and it returns all keybord and mouse events happening in that window, including every mouse button.

Hi Jelte,
could be a little precise about what you mean "go on forever"? Your screen is limited insize, true, but so is the table under your mouse, isn't?
I don't if that could be of any use to you, but i recently posted a patch that enables you to control two sliders at once with you mouse. The workings are very simple really, but maybe that could give you some ideas. the name of the thread is Bi-Dimensional real time control.
