Find intersecting points between vectors

Question

Hi,

I try to find the blue vector in my image. Hopefully the the picture says enough, otherwise I'll be happy to elaborate. Any help would be appreaciated! The unit vectors and constants are known and will all be wit$$anonymous$$n reasonable bounds. XY-space.

I'll just give you the code and hope not to have missed anyt$$anonymous$$ng lol

 Vector2 V1;
 Vector2 V2;
 float const1;
 float const2;
 
 Vector2 U1 = V1 / V1.length() * const1;
 Vector2 U2 = V2 / V2.length() * const2;
 
 float t = ((U1.y + U2.y) * V2.y/V2.x + U2.x + U1.x)/(V1.y - V1.x * V2.y / V2.x);
 Vector2 point = t * V1 + //If it doesn't works, set t$$anonymous$$s to -
                 new Vector2(V1.y, -V1.x) * const1 / V1.length();

I do really hope I've not missed anyt$$anonymous$$ng...

Will check it in a while. Both vectors are 2D,right? And they are all centered in the origin? That math will only work if your center is the origin

Took away my old answer, found out a minor mistake by me, works like a charm! Thanks a lot!
