Temperature Script?

Anyone have a basic script outline of a temperature meter (a GUI starting with 98 degrees and steadily decreasing or increasing), and can change temperature when in range of a specific object (i.e: a campfire for warmth)?

If someone could outline a script that starts me off, that’d be absolutely great. Thanks!

OnTriggerEnter () {

OnTriggerExit() {

Temperature will move closer to the surrounding temperature over time. For a rather crude approximation I would do the following.

  • Create a script that records the temperature of each GameObject
  • Use a sphere cast at some defined frequency, or use OnTriggerStay, to get the temperature of all nearby GameObjects
  • Adjust the temperature closer to the average of all the temperatures of nearby objects
  • You could also define an ambient temperature to use if no GameObjects are close

For an accurate approximation grab a university level physics or engineering textbook, and look up the chapter on thermodynamics and heat transfer. This is not a light topic, I’d suggest running with an approximation rather then trying to create accurate temperature physics.

i know this is a very old question but i think this code snipet works perfectly

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class temp : MonoBehaviour
    public float sc1 =3f; //specific heat capacity
    public float sc2 = 6f;
    public float sm1 = 100f; //mass
    public float sm2 =200f;
    public float sk1=0.609f;//insulation
    public float sk2 = 0.58f;
    public float tickspeed = 0.25f;
    public float surfacearea = 25;
    float C1; // heat capacity
    float C2;

    public float T1 = 370f; // temperature in kelvin
    public float T2 = 315f;
     float ΔQ;
     float Q1;
     float Q2;// thermal energy
    // Start is called before the first frame update
    void Start()

    // Update is called once per frame
    void FixedUpdate()
        C1 = sc1 * sm1;
        C2 = sc2 * sm2;
        ΔQ = tickspeed * Mathf.Min(sk1, sk2) * (T1 - T2) * surfacearea * surfacearea; 
        T1 = T1 - ΔQ / C1;
        T2 = T2 + ΔQ / C2;
        Q1 = C1 * T1;
        Q2 = C2 * T2;
