为什么我的 GUI 健康条从两个方向而不是从一个方向流出？

Question

我想这是因为我没有通过代码告诉它我希望它从哪个方向排出，但我认为这对 unity 来说已经很明显了，因为这是我在层次结构中的 GUI 图像类型上的设置已填充并且填充原点设置为左侧。无论如何，我假设我的代码中的某些内容可能会告诉它从两侧排出？我的生命条从两侧流出，但我只希望它从左侧流出。有人有解决办法吗？

public class meterDrain : MonoBehaviour {

public float maxHungerMeter = 100f;
public float curHungerMeter;
public RectTransform hungerMeter;

public float maxThirstMeter = 100f;
public float curThirstMeter;
public RectTransform thirstMeter;

public float maxEnergyMeter = 100f;
public float curEnergyMeter;
public RectTransform EnergyMeter;

public float maxBowelsMeter = 100f;
public float curBowelsMeter;
public RectTransform bowelsMeter;

public float maxMoraleMeter = 100f;
public float curMoraleMeter;
public RectTransform moraleMeter;


void Start () 
{
    curHungerMeter = maxHungerMeter;    
    curThirstMeter = maxThirstMeter;
    curEnergyMeter = maxEnergyMeter;
    curBowelsMeter = maxBowelsMeter;
    curMoraleMeter = maxMoraleMeter;
}

// Update is called once per frame
void Update ()
{
    TakeDamage ();
}

void TakeDamage(float amount = 10f){    //as of now the meters are being drained towards the middle from both sides. need to fix that
    {
        curHungerMeter -= amount * Time.deltaTime;
        curThirstMeter -= amount * Time.deltaTime;
        curEnergyMeter -= amount * Time.deltaTime;
        curBowelsMeter -= amount * Time.deltaTime;
        curMoraleMeter -= amount * Time.deltaTime;
    }

    if (hungerMeter == null)    //for some reason, this is being applied all meters besides hunger, even though i didn't tell it to. *shrugs* works for me.
        return;

    hungerMeter.sizeDelta = new Vector2 (curHungerMeter, hungerMeter.sizeDelta.y);
    thirstMeter.sizeDelta = new Vector2 (curHungerMeter, thirstMeter.sizeDelta.y);
    EnergyMeter.sizeDelta = new Vector2 (curHungerMeter, EnergyMeter.sizeDelta.y);
    bowelsMeter.sizeDelta = new Vector2 (curHungerMeter, bowelsMeter.sizeDelta.y);
    moraleMeter.sizeDelta = new Vector2 (curHungerMeter, moraleMeter.sizeDelta.y);



}
}

Answer 1

您正在通过设置其 RectTransform 来更改健康栏的大小，而不是您想要更改图像组件的 Fill Amount。为此，您需要将仪表对象（hungerMeter 等）的类型更改为 Image。

为什么我的 GUI 健康条从两个方向而不是从一个方向流出？

why is my GUI health bar draining from both directions instead of from only 1 direction?
