# How to make object follow line vectors

I’m using the below code to create a line which shows an objects intended path of travel. It works really well, but I can’t for the life of me figure out how to use the vectors created to have an abject follow that path at a set speed. Would really appreciate someone pointing me in the right direction.

``````void DrawQuadraticBezierCurve(Vector3 point0, Vector3 point1, Vector3 point2)
{
lr.positionCount = 200;
float t = 0f;
B = new Vector3(0, 0, 0);
for (int i = 0; i < lr.positionCount; i++)
{
B = (1 - t) * (1 - t) * point0 + 2 * (1 - t) * t * point1 + t * t * point2;
lr.SetPosition(i, B);
t += (1 / (float)lr.positionCount);
}
}
``````

Really dirty attempt to do it. Stored the points on a Vector3 array and used a simple logic on Update to switch between each vector, passing its position to the gameobject transform.position. `There should be a better way of doing this, this is just a simple test that could give you a clue to come up with a better answer.`

``````public float stepDuration = 0.01f;
public bool isActive;
private Vector3 B;
private Vector3[] BPoints;
private int index;
private float t;

private void Update()
{
if (isActive)
{
t += Time.deltaTime;
if (t / stepDuration >= 1)
{
index++;
t = 0.0f;
}
if (index <= BPoints.Length - 1)
{
Vector3 targetPosition = new Vector3(BPoints[index].x, transform.position.y, BPoints[index].z);
transform.position = targetPosition;
}
}
}

void DrawQuadraticBezierCurve(Vector3 point0, Vector3 point1, Vector3 point2)
{
BPoints = new Vector3[200];
lr.positionCount = 200;
float t = 0f;
B = new Vector3(0, 0, 0);
for (int i = 0; i < lr.positionCount; i++)
{
t += (1 / (float)lr.positionCount);
B = (1 - t) * (1 - t) * point0 + 2 * (1 - t) * t * point1 + t * t * point2;
lr.SetPosition(i, B);
BPoints *= B;*
