Implementation of PVector.setHeading()

[arijit4]

There's an method named PVector.setHeading() in p5.Vector class of p5.js to set the direction of an vector to any given angle. But there's no such option in Processing. It can be settled down easily. But the function seems more self explanatory and easy to understand. It also goes well with the PVector.heading() method already present in Processing.

An implementation might look like the following :

void setHeading(float angle) {
    this.rotate(angle - this.heading());
}

Adding it for parity with p5.js… Here's the full implementation from there:

_main.default.Vector.prototype.setHeading = function setHeading(a) {
  var m = this.mag();
  this.x = m * Math.cos(a);
  this.y = m * Math.sin(a);
  return this;
};

@benfry In 673a19e, you added

public PVector setHeading(float angle) { 
    float m = mag();
    x = m * Math.cos(a);
    y = m * Math.sin(a);
    return this;
 }

shouldn't it be the following?

public PVector setHeading(float angle) { 
    float m = mag();
    x = m * Math.cos(angle);
    y = m * Math.sin(angle);
    return this;
 }

Yes, and it was immediately fixed in the next commit.

@benfry PVector.setHeding() isn't highlighted as other methods in PVector. But it works perfectly though...
