GUI health status
I have a canvas with a panel, in the panel i want to display an image for each healthpoint the player has, max 20.
The code i use for this is:
float _slots = 0f;
for (int i = 0; i < 2; i++) {
for (int k = 0; k < 10; k++) {
if (_slots <= PlayerHealthPoints) {
GameObject Heart = (GameObject)Instantiate (HeartImage);
HeartSlots.Add (Heart);
Heart.transform.parent = HeartPanel.transform;
Heart.name = "Heart" + i + "," + k;
Heart.GetComponent<RectTransform> ().position = new Vector3 (x, y, 0);
_slots ++;
}
x += 50;
if (k == 9) {
x = 35;
y = y - 50;
}
}
}
I can instantiate and show 20 images fine, the problem is showing less if the player has less health, i tried the if statement but its not working.
I dont want a slider to represent the health, what i want is images like in the Zelda games.

So I highly suggest making a gameobject with two child images, the first is your overlay the second is your underlay (a grey heart for example).
Then this code should be suitable, attach it your heartPanel:
public class TEST
{
float playerHealth;
float slots = 0f;
float x = 0;
float y = 0;
float amountInX;
float amountInY;
float heartSlots;
float health;
List<GameObject> HeartSlots = new List<GameObject>();
GameObject heartObject;
float CalculateHealth()
{
return heartSlots = health / 20;
}
void Start()
{
for (int i = 0; i < amountInY; i++)
{
for (int k = 0; k < amountInX; k++)
{
GameObject Heart = (GameObject)Instantiate(heartObject);
HeartSlots.Add(Heart);
Heart.transform.SetParent(gameObject.transform, false);
Heart.name = "Heart" + i + "," + k;
Heart.GetComponent<RectTransform>().position = new Vector3(x, y, 0);
slots++;
x += 50;
if (k == 9)
{
x = 35;
y = y - 50;
}
}
}
}
void UpdateHearts()
{
foreach(GameObject heart in HeartSlots)
{
heart.gameObject.transform.GetChild(0).GetComponent<Image>().enabled = false;
}
for (int i = 0; i < heartSlots; i++)
{
HeartSlots[i].gameObject.transform.GetChild(0).GetComponent<Image>().enabled = true;
}
}
void Update()
{
UpdateHearts();
}
}
Haven't fully read it through but you get the idea. You'd have to implement bits of it yourself like update the playerHealth etc.
