Question about Flee vs. Seek in Nature of Code 2

[kind grove]

Hello people. I’m following the Nature of Code 2 video about Flee (https://editor.p5js.org/codingtrain/sketches/v-VoQtETO) and I’m having some confusion about the following part of the code in the definition of the class Vehicle:

return this.seek(target).mult(-1);
}

seek(target) {
let force = p5.Vector.sub(target, this.pos);
force.setMag(this.maxSpeed);
force.sub(this.vel);
force.limit(this.maxForce);
return force;
}```

I think conceptually the “flee” function is supposed to make sure that the desired velocity of the vehicle points away from the target, therefore the flee desired velocity = seek desired velocity * (-1), correct? But seems in the code above rather it is the steering force that is being flipped instead by the *(-1)…I don't think they are equivalent. Is my thinking correct? Appreciate your input as always 😉

Your thinking is absolutely correct, in that the Dan's implementation of Flee does not match that proposed in the paper, and in some sense can be said to be "incorrect".
