How can I do multiple pickers using the Picking library?

in Contributed Library Questions • 3 years ago

Hi,

I'm in the process of writing a sketch using a database. I'm trying to link picking ids to database row ids. I've got several tables I'm pulling data from and would like to have a separate picker for each table for different visualizations.

Does anyone have an idea on how to distinguish which picker an object is associated with?

For example, I draw 1000 circles and 1000 squares. The circles have a picker and the squares have a picker. I can get the ids from each picker if I mouse over an object, but how do I distinguish if it's a circle or square that the mouse is over?

Or will the library work as long as the buffer colors are not the same? Or as long as the objects aren't overlapping?

Thanks,

Max

I haven't been able to have multiple pickers (from the picker library) operate at the same time. The second one that I initialize doesn't work well, even when the shapes aren't overlapping.

I now this is a late reply and I feel sorry about that.

Anyway : you can't use two pickers at the same time, because a picker acts as a "recorder" and a PApplet can't have more than one recorder.

If you have only one window running, then there is no reason you would need more than one picker actually. In the example above, you should associate a unique id to each object. You just need to find a clever way to distinguish circles and squares. Maybe odd and even ids?
