This question is probably quite basic as I am still quite new to programming in pd.

I have checked the help docs concerning the use of linear and spline path but I haven't been able to figure out how to use [tabwrite] properly. It is my understanding that the linear/spline path objects must get their coordinates from an array(s.) I have found [soundfiler] for example, but I am looking for a way to graph movement into an array rather than sound.

In other words is there a way to track the movements of the mouse within the gemwindow and graph them into an array?

Also, is there a way to save this graph as a series of coordinates in a text file that could be saved and read later?

look at the conways game of life example. it uses arrays to do exactly this

That's amazing. Thx. I'll be sure to post something once I figure it out.
I hesitated to check the game of life before because it's listed under glsl and I haven't had much luck understanding how shaders work or how to make one. Cheers for the tip.
