I need help with raycasts and with color of gameobject [SOLVED]

Question

So i am creating my second game and I want this game to be finished. I am creating a 3d Game. My player is a stationary object and he is looking at a cube. So the cube is on the ground and the cube is changing colors from red to green. I want to make my player lose if he clicks on the cube while the color of the cube is red. I Have been trying for ages and I can't find a fix to this problem. I'm using raycasts because i think this will be the easiest way but i just can't get the script to work. I hope that is all the information i needed to give. Im open to all suggestions on how to do this without raycasts and with something else. Thanks.

Answer 1

Hello. You can do a simple thing like this:

 public class CubeStatus : MonoBehaviour
 {
       public bool isGreen = false;
       
       void SwapColor(bool green)
       {
             // Change color material
             isGreen = green;
       }
 }

In this way you've saved the state of the cube.

Where you do the Raycast, add a reference for the CubeStatus component:

 public class RaycastShooter : MonoBehaviour
 {
     [SerializeField] CubeStatus status; // Assign it in the inspector
 
     public void Shoot()
     {
         RaycastHit hit;
         if (Physics.Raycast(rayOrigin, forwardVect, out hit, range))
         {
             if (hit.transform.CompareTag("TheCube"))
             {
                 if (status.isGreen)
                     // we've hit good
                 else
                     // game over               
             }
         }
     }
 }

Look that in this case the Cube must have the tag "TheCube", otherwise it will not pass the if condition.

maybe you try

if(hit.gameobject.meshrender.sharedmaterial.color == color.green) { //do stuff }

Thank you both for your answers here :). @silvematt @dahiyabunty1 Setting booleans is such a obvious thing to do idk why I didn't do it tho:/. I will try both solutions today and I will let you know what works for me. I have a problem with the first script tho. So on the first script when I change the color of the cube won't it stay the same color all the time? Right now Im using coroutines for the color changing on the cube beacuse I want it constantly to be changed not only one time. The second script is good thank you:)
