public void SetPosition(int index, Vector3 position);

Parameters

indexWhich position to set.
positionThe new position.

Description

Set the position of a vertex in the trail.

You can only use this method to modify existing positions in the Trail. You cannot use it to add new positions.

When setting multiple positions, consider using SetPositions instead because it is much faster than making individual function calls for each position.
