In Windows, p3d always reports an error. During the check, the previously written items are lost. For Linux, it can be displayed, but smooth () cannot be used, saying that my hardware does not support it. In addition, the code written in Linux cannot be copied. paste a picture to make it happen.

The two squares are converted along different coordinates.

Bytes -------------------------------------------------------------------------------------

Millis(): Millisecond

Second() Seconds

Minute() Points

Hour() Hour

void setup(){  size(300,300);}void draw(){  background(0);  int ms = millis();  int s = second();  int m = minute();  int h = hour();  fill(255,0,0,100);  rect(ms/100,0,30,70);  fill(0,255,0,100);  rect(s*2,75,30,70);  fill(0,0,255,100);  rect(m,150,30,70);  fill(0,255,255,100);  rect(h,225,30,70);}

The four small rectangles are moved by time.
