Get the closest waypoint to a position. Uses a direction vector to select the correct lane.
Declaration
public static int GetClosestWaypoint(Vector3 position, Vector3 direction)
Parameters
Name
Description
position
The index of the vehicle to be instantiated. Can be active or inactive at the time of instantiation.
direction
The vehicle will be instantiated with the front wheels axis on this position.
Returns
int - The index of the closest waypoint.
Example
using Gley.TrafficSystem;
using UnityEngine;
public class Test : MonoBehaviour
{
public GameObject playerCarGo;
private void Update()
{
if(Input.GetKeyDown(KeyCode.Space))
{
ShitchPlayerCarWithTrafficVehicle();
}
}
private void SwitchPlayerCarWithTrafficVehicle()
{
// Get the current position and rotation of the player car
Vector3 currentCarPosition = playerCarGo.transform.position;
Quaternion currentCarRotation = playerCarGo.transform.rotation;
// Get the rigidbody of the player car.
Rigidbody manualRg = playerCarGo.GetComponent<Rigidbody>();
// Deactivate the player car
playerCarGo.SetActive(false);
// Get the closest waypoint from the player car in the moving direction.
// Direction is important because the closest waypoint might be on the other way.
int nextWaypointIndex = API.GetClosestWaypoint(playerCarGo.transform.position, playerCarGo.transform.forward);
// An index of the vehicle that looks exactly with the player car
int trafficVehicleIndex = 0;
// Instantiate the traffic vehicle
API.InstantiateTrafficVehicle(trafficVehicleIndex, currentCarPosition, currentCarRotation, manualRg.velocity, manualRg.angularVelocity, nextWaypointIndex);
}
}
