not sure what your goal is
here we start from 0 using timer1, so the block moves every 1,1 seconds
int xPos = 0;
int timer1 ;
void setup() {
size(400, 400);
noStroke();
}
void draw() {
background(220);
fill(255, 200, 40);
rect(xPos, 30, 40, 40);
if (millis() - timer1 > 1100) {
xPos+=10;
timer1=millis();
}
}
//
