Getting float variable of child object in uinty

Question

I have Unit gameObject which contains 2 subOnjects in it: Monster and HealthBar. Now Health has float - max_Health which I want to access using onTriggerEnter.

print(co.transform.GetChild(1));

Gives me "HealthBar" Which means I get correct subobject but now how can I get meaning of its float variable "max_Health" ?

I've tryied this:

print(co.transform.GetChild(1).transform.Find("max_Health"));

But got Null. That's wrong. How can I get it ?

print(co.transform.GetChild(1).Find("max_Health")); not working

print(co.transform.GetChild(1).Find("float max_Health")); not working.

What else can be done ??????

UPDATE

GameObject GG = GameObject.Find("GameObject co.transform.GetChild(1)");
Health bScript = GG.GetComponent<Health>();
print(bScript.max_Health);

gives me error

NullReferenceException: Object reference not set to an instance of an object
Tower.OnTriggerEnter (UnityEngine.Collider co) (at Assets/Scripts/Tower.cs:23)

Your question does not show that you tried. I don't see GetComponent anywhere in your question. That is the correct way to do this, update your question to show what you tried with `GetComponent()`. — Scott Chamberlain, Mar 01 '16 at 18:15
Probably I'm close but doing something wrong. As you can see I'm not pro with coding :) Can you check my last update ? — David, Mar 01 '16 at 18:38
You shouldn't be using `Find()` at all in this case, if you can already access the GameObject's transform with `co.transform.GetChild(1)`. Just use `GetComponent()` with the results of `GetChild(1)`, like so: `co.transform.GetChild(1).GetComponent()` This will give you a reference to the `Health` script component on the child, so you can access any (public) variables/methods you have there. — Serlite, Mar 01 '16 at 19:14
