To temporarily multiply a vector in p5.js, you can use the mult() function available in the p5.Vector class. Here's an example:

1
2
3
4
let myVector = createVector(2, 3); // Create a vector with x = 2, y = 3
let multipliedVector = myVector.copy().mult(2); // Make a copy of the original vector and multiply it by 2 temporarily

console.log(multipliedVector); // Output the multiplied vector


In the above example, myVector.copy().mult(2) creates a copy of the original vector myVector and multiplies it by 2 temporarily without modifying the original vector. You can use the mult() function to multiply vectors by a scalar value to scale them up or down as needed.
