Extremely Fast Travel

Questions & Answers
1

I have been messing around with simulating real life space distances, and scales. I solved floating point problems, but when I try to travel at real life light speed, my script cannot correct fast enough to avoid floating point problems. I am wondering if there is anyway to make this correction faster than every frame. Here is the script:

using UnityEngine;
using System.Collections;

public class Reposition : MonoBehaviour {

	public float maxDist;
	public GameObject[] sceneObjects;
	void Awake () {
		sceneObjects = GameObject.FindGameObjectsWithTag("Respawn");
	}
	
	void Update () {
		Vector3 xpos = new Vector3(0, transform.position.y, transform.position.z);
		Vector3 ypos = new Vector3(transform.position.x, 0, transform.position.z);
		Vector3 zpos = new Vector3(transform.position.x, transform.position.y, 0);


		if(transform.position.x > maxDist){
			transform.position = xpos;

			foreach(GameObject obj in sceneObjects){
				obj.transform.position = new Vector3(obj.transform.position.x - maxDist, obj.transform.position.y, obj.transform.position.z);
			}
		} 

		if(transform.position.x < -maxDist){
			transform.position = xpos;
			
			foreach(GameObject obj in sceneObjects){
				obj.transform.position = new Vector3(obj.transform.position.x + maxDist, obj.transform.position.y, obj.transform.position.z);
			}
		}

		if(transform.position.y > maxDist){
			transform.position = ypos;

			foreach(GameObject obj in sceneObjects){
				obj.transform.position = new Vector3(obj.transform.position.x, obj.transform.position.y - maxDist, obj.transform.position.z);
			}
		}

		if(transform.position.y < -maxDist){
			transform.position = ypos;
			
			foreach(GameObject obj in sceneObjects){
				obj.transform.position = new Vector3(obj.transform.position.x, obj.transform.position.y + maxDist, obj.transform.position.z);
			}
		}

		if(transform.position.z > maxDist){
			transform.position = zpos;

			foreach(GameObject obj in sceneObjects){
				obj.transform.position = new Vector3(obj.transform.position.x, obj.transform.position.y, obj.transform.position.z - maxDist);
			}
		}

		if(transform.position.z < -maxDist){
			transform.position = zpos;
			
			foreach(GameObject obj in sceneObjects){
				obj.transform.position = new Vector3(obj.transform.position.x, obj.transform.position.y, obj.transform.position.z + maxDist);
			}
		}
	}
}

If you need to do something faster that every frame (which is odd), you can put it in a for loop.

The frame will not progress until the for loop is done.

    //Adds 1 per frame
    //Runs code once per frame
    Update(){
     //code
     number1 ++;
    }
    
    //Adds 1, twice, per frame
    //Runs code twice per frame
    Update(){
     for(int i=0; i<2; i++){
      //code
      number1 ++;
     }
    }
