Hi everyone! Help to solve problem! I need that script to read “health” from Properties!(And script Properties is attached to the chacacter with tags “Air” and “Ground”)
Can not understand what is not right.

`using UnityEngine;
using System.Collections;

public class Power_ups : MonoBehaviour {
public float Health;	
public GameObject bullet;
public float damage = 100;
public GameObject btn_power_up;
	
	void Awake(){
		bullet.SetActive(false);
	}
	
	void Start(){
	 UIEventListener.Get(btn_power_up).onClick += PowerStart;	
	}

	void PowerStart (GameObject btn_power_up) {
		bullet.SetActive(true);
	}
 
	void  OnTriggerEnter (  Collider hit   ){
    if(hit.gameObject.tag == "Air")
    {
       bullet = hit.gameObject;
       TakeDamage(); 
    }
		if(hit.gameObject.tag == "Ground")
    {
       bullet = hit.gameObject;
       TakeDamage(); 
    }
}
 
	void  TakeDamage (){
	    health properties = GetComponent<Properties>();
		Health = properties.health;
		Health -= damage;
		

    }
}

You’re trying to assign Properties object to variable of type health, should be:

 void  TakeDamage (){
       Properties properties = GetComponent<Properties>();
       Health = properties.health;
       Health -= damage;
 
 
    }
