How can I get an object to intercept a moving object's path?

Basically, just Vector math. You're going to want to work out a how long your stationary object is (probably) going to take to get to an intercept point on the other one, then work out where the other one is going to be at that time, probably by multiplying that object's movement vector by the time.

You could also run a loop which moves the intercept point around until it finds the best match, knowing the other objects speed and path. It's problems like this that always prompt me to keep plenty of scratch paper near my desk.

But as a third point, typically for a basic 'zombie' AI, I just have the object move to where the moving object is, and that creates a nice chase thing.

 This is what i did using simple maths and physics works 100% precise

     public Vector3 CalculateInterceptionPoint3D(Vector3 PC, float SC, Vector3 PR, Vector3 VR)
     {
         //! Distance between turret and target
         Vector3 D = PC - PR;
 
         //! Scale of distance vector
         float d = D.magnitude;
 
         //! Speed of target scale of VR
         float SR = VR.magnitude;
 
         //% Quadratic EQUATION members = (ax)^2 + bx + c = 0
 
         float a = Mathf.Pow(SC, 2) - Mathf.Pow(SR, 2);
 
         float b = 2 * Vector3.Dot(D, VR);
 
         float c = -Vector3.Dot(D, D);
 
         if ((Mathf.Pow(b, 2) - (4 * (a * c))) < 0) //% The QUADRATIC FORMULA will not return a real number because sqrt(-value) is not a real number thus no interception
         {
             return Vector2.zero;//TODO: HERE, PREVENT TURRET FROM FIRING LASERS INSTEAD OF MAKING LASERS FIRE AT ZERO!
         }
         //% Quadratic FORMULA = x = (  -b+sqrt( ((b)^2) * 4*a*c )  ) / 2a
         float t = (-(b) + Mathf.Sqrt(Mathf.Pow(b, 2) - (4 * (a * c)))) / (2 * a);//% x = time to reach interception point which is = t
 
         //% Calculate point of interception as vector from calculating distance between target and interception by t * VelocityVector
         return ((t * VR) + PR);
     }

@PoyrazGoksel how do I make my game object move to the point of interseption?
