scalar * vector

[Yours3lf]

Hi,

I'm stuck at this.

I can scale a vector by a scalar (float), but I can't do it in the opposite way.

vec2f a = vec2f(1.0f, 1.0f);
float b = 1.0f;
a = a * b; //this works
a = b * a; //this doesn't 

Here's the function I'm using

vec2f vec2f::operator*(float num)
{
    return vec2f(v[0] * num, v[1] * num);
}

how can I make it work both ways?

Best regards,

ok whatever I solved it:)

I just needed to declare a non-member version of it:
vec2f operator*(float num, vec2f vec);

and define it as:

vec2f operator*(float num, vec2f vec)
{
  return vec * num;
}

Make the operator a friend function, and overload it for (vec2f,num) AND (num,vec2f).
