The Vuo sketch works by creating a list of 200 ovals. each time the ‘Build List’ index port reaches 100 an event signal is sent from the ‘Select Event Output’ to decriment the y-value by 0.02. But since I’m not sure how to reset the ‘Set Count’ port for the x-axis (sending the same event to this port doesn’t work) I get the wrapped around version in the image below.
What I want is to also reset the x-value to -1 each time 100 ovals are reached so that the oval rows are aligned perfectly vertically.
The general concept is that you need two lists, if one list is for your x coordinates, then y coords is a list of the x coord list (your for loop does y coords first, then x). The pic shows an example, Make Points Along Line generates a list, you can use two, one for x range, one for y range.
I know this pic shows a different approach from using Build List, certainly possible with that node, but there are built in tools for grids that solve the issue. Controlling the order grid items generate would be another matter, there’s an exercise that might be worth pursuing.
If you want to animate how the grid generates on screen, left to right, top to bottom, etc. would have to also animate end point on Make Point Along Line. I think that would work… left alone it always fills the range, i.e., generates from center out.
