a	Start point
b	End point

Returns

Normal point

Definition at line 48 of file VectorExtensions.cs.

    {
        var ap = p - a;
        var ab = (b - a).Normalized();
        var dot = ap.Dot(ab);
        return a + (ab * dot);
    }

Jitter()

static Vector2 VectorExtensions.Jitter ( this Vector2  vector, float  coef  )

inlinestatic

Add a random value to X and Y components.

Parameters

vector	Current vector
coef	Coefficient

Returns

Vector with jitter

Definition at line 33 of file VectorExtensions.cs.

    {
        var vec = new Vector2(vector.x, vector.y);
        vec.x += MathUtils.Randf() * coef;
        vec.y += MathUtils.Randf() * coef;
        return vec;
    }

NormalizeTo()

static Vector2 VectorExtensions.NormalizeTo ( this Vector2  vector, float  length  )

inlinestatic

Normalize a vector using a specific length.

Parameters

vector	Current vector
length	Target length

Returns

Normalized vector

Definition at line 14 of file VectorExtensions.cs.

    {
        var vec = new Vector2(vector.x, vector.y);
        var len = vec.Length();
        if (len > 0)
        {
            len /= length;
            vec.x *= len;
            vec.y *= len;
        }
        return vec;
    }
