Move a rectangle across a window by incrementing a variable. Start the shape at

Question

Move a rectangle across a window by incrementing a variable. Start the shape at x coordinate 0 and use an if statement to have it stop at coordinate 100. Rewrite the sketch to use the if statement. Fill in the missing code.

// Rectangle starts at location x

float x = 0;

void setup() {

size(200, 200);

}

void draw() {

background(255);

// Display object

fill(0);

rect(x, 100, 20, 20);

// Increment x

x = x + 1; what should I put after this?

Explanation / Answer

float x = 0; void setup() { size(200,200); } void draw() { background(255); // Display object fill(0); rect(x,100,20,20); // Increment x x = x + 1; // If x is greater than 100 if (x > 100) { // Set it back to 100 x = 100; } // Using constrain instead // x = constrain(x,0,100); }
