racing game multiple checkpoint system query

Question

currently I have placed 2 checkpoints, halfcheckpoint and finalcheckpoint. at first finalcheckpoint is disabled this is script attached to halfcheckpoint

void OnTriggerEnter() { finalcheckpoint.SetActive(true); halfcheckpoint.SetActive(false); }

so when player reaches halfcheckpoint, finalcheckpoint is enabled and halfcheckpoint is disabled

this is for finalcheckpoint

void OnTriggerEnter() { finalcheckpoint.SetActive(false); halfcheckpoint.SetActive(true); }

so when player reaches finalcheckpoint, finalcheckpoint is disabled and halfcheckpoint is enabled again. this works perfect.

but the problem is I want to have more than 2 checkpoints like 8 or 10 or something. so I will have to write separate script for all checkpoint1, checkpoint2, etc and attach it to respective checkpoint. I dont want to do that. is there a way I can write 1 script and attach it to parent gameobject of all the children checkpoints ??????

Add script to your player that detects checkpoints.

 GameObject lastCheckpoint;
 void OnTriggerEnter(Collider other ) {
  if (other.gameObject.tag == "checkpoint") {
     if (lastCheckpoint) {
        lastCheckpoint.setActive(false);
     }

     other.gameObject.setActive(true);
     lastCheckpoint = other.gameObject;
   }

Add the tag to your checkpoints.

I dont understand. I'm new to programing. explaining each and every step will be very helpful. thank you

what I want to do is create empty(CheckPoints), make all checkpoints its child. attach script to this empty as follows

public class CheckPoints : $$anonymous$$onoBehaviour {

 public GameObject CheckPoint1;
 public GameObject CheckPoint2;
 public GameObject CheckPoint3;
 public GameObject CheckPoint4;
 void OnTriggerEnter(*CheckPoint2*)
 {
     CheckPoint3.SetActive(true);
     CheckPoint2.SetActive(false);
 }
 void OnTriggerEnter(*CheckPoint3*)
 {
     CheckPoint4.SetActive(true);
     CheckPoint3.SetActive(false);
 }

}

and so on how do I make it work

Yeah sure. So do you just want to set them active and not active just for visual effects, or do you need to record the checkpoints that have been passed through?
