Trying to get 2 floats synced up.
Hey guys, using NGUI to make a Health bar, problem is that the progress bars float has a value of 0 to 1, but my Health is 0 - 100, I was wondering how I would be able to hook it up so that the health and the NGUI bar is the same value and will increase and decrease respectfully.
Here's what I have so far, I just don't know how to hook it up.
using UnityEngine;
using System.Collections;
public class HealthBarLink : MonoBehaviour {
private UISlider _slider;
public GameObject Player;
void Update()
{
_slider = GetComponent<UISlider>();
Health = Player.GetComponent<Health>();
Health.curHealth == _slider.rawValue;
}
}
The rawValue part is where I'm having trouble.
I knew it'd have to be something like, not sure how to properly implement it in code though. :/
void Update()
{
_slider = GetComponent<UISlider>();
Health = Player.GetComponent<Health>();
_slider.rawValue = Health.curHealth/100;
}
I think this is what you want. However you dont need to do it in update, just change the rawValue to curHealth/100 whenever the health decreases. This way you do not need to check/change the value every frame. Heres an example of how to update the rawValue when your player takes damage.
//Health.cs
void Damage(float damage)
{
curHealth-=damage;
_slider = GetComponent<UISlider>();
_slider.rawValue=curHealth/100;
}
You probably want to do the following:
// Cache these values on startup
void OnEnable ()
{
_slider = GetComponent<UISlider>();
Health = Player.GetComponent<Health>();
}
// Make UISlider match health
void Update()
{
_slider.sliderValue = Health.curHealth/Health.maxHealth;
}
Assuming you have a Health.maxHealth. :-)
I hope this helps!
Yeah, like hijinxbassist says - you should probably only update sliderValue in your "Damage" code, as it'll be faster. (and it'll be the only place the value of the slider changes)
