Inconsistent result from calculation

Hello @RMurphy195,

A related example:

Why circle disappears at y-coordinates ~ 250

Hello, This was in my Drafts and a late response… it may still be helpful to some. It is because the math is exceeding the maximum value of an integer at some point in the code: https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html This code shows what happens to y1 when millis() (an integer) is greater than 14654: [image] The above code shows where the point of concern is in the code. You are using millis()/1000 for time. Consider using this floating point division…
