Raycast check bool on hit object

Questions & Answers
1

I have a script for an animal that has the bool : isDead. I want my raycast to check if isDead is true or not. I have tried messing around with the syntax but I can’t figure it out. Thank you in advance!

using UnityEngine;
using System.Collections;

public class RayCast : MonoBehaviour {

	Camera cameraMain;
	float showWaterText;
	public PlayerNeeds player;

	void Start() {
		cameraMain = GetComponent<Camera>();
	}

	void OnGui()
	{
		if (showWaterText == 1) {
			print ("Water 2");
			 GUI.Box (new Rect ((Screen.width) / 2 - (Screen.width) / 8, (Screen.height) / 2 - (Screen.height) / 8, (Screen.width) / 4, (Screen.height) / 4), "Press E to drink."); 
		}
	}

	void Update() {
		Ray ray = cameraMain.ViewportPointToRay (new Vector3 (0.5F, 0.5F, 0));
		RaycastHit hit;
		if (Physics.Raycast (ray, out hit, 3)) {
			if (hit.transform.gameObject.tag == "Water") {
				print ("Water");
				showWaterText = 1;
				if(Input.GetButton ("Use"))
				{
					player.playerThirst = 20;
				}
			}
				else{
				showWaterText = 0;
			}

		}
		if (Physics.Raycast (ray, out hit)) 
		{
			if(hit.transform.gameObject.tag == "Animal")
			{
				if(hit.collider.gameObject.GetComponent<Animal>.isDead)
				{

				}
			}
		}
	}



}

PS. The GUI box doesn’t show up when I look at the water. If you could also shed some light on that I would greatly appreciate it.

if(hit.collider.gameObject.GetComponent.isDead)
{

                 }

has to be

if(hit.collider.gameObject.GetComponent<Animal>().isDead)
                 {
 
                 }

Note the “()” as part of the GetComponent function.

As fo the GUI Box, create a simpler rectangle for it to see if maybe you are trying to draw it outside of the screen space, and check the inspector if the watertext variable is 1 when you look at the water.
