无法在 Unity 中更改 Inspector 变量中的数组大小? [英] Unable to change array size in Inspector variable in Unity?

问题描述

据我所知，这是如何设置矢量大小"

public Color[] teamAColors = new Color[4];

但是当代码运行时它看起来像这样

我为 [4] 设置的数字似乎无关紧要，大小始终保持为 6.我什至不确定 6 数字来自哪里，因为我没有为该数字设置任何内容.

我什至尝试过

 public Color[] teamAColors;

然后让我的数组自动填充长度，但这也不会改变 6.

解决方案

很简单

 public Color[] teamAColors;

但是那个6"呢?不会消失"的价值?

但是您偶然发现了重置"GOTCHYA 团结一致！

只需尝试使用不同的变量名称...

public Color[] teste;

看到了吗?

就是这样，工作正常.您可以动态设置大小，只要不要在代码中输入大小.

秘密在这里:

Unity坚持"以复杂的方式序列化值.

如果您在代码中设置大小甚至一次，Unity记住"即使您随后更改了代码，也是如此.

有一种方法可以重置这个内部"value .. 寻找著名的小重置按钮.

它附在微小的 Cog 符号上.

要记住的关键规则是:

永远不要在代码中为 Unity 中的公共变量设置默认值！！

公共浮点数x；//做这个公共浮动 x=2f；//通常永远不要这样做

当你在做的时候，这里有一个非常方便的技巧.试试这个...

[Header(这有多好?")]公众持股量 x；

这是一个更酷的！试试吧！

[范围(2f,4f)]公众持股量 x；

From what I have read this is how a vector "Size" is set

public Color[] teamAColors = new Color[4];

But when the code is run it looks like this

It doesn't seem to matter what number I put for the [4], the Size always stays 6. I am not sure where the 6 number is even coming from as I have not set anything to that number.

I have even tried to

 public Color[] teamAColors;

And then let my array auto populate the Length, but that doesn't change the 6 either.

解决方案

It's simply

 public Color[] teamAColors;

But what about that "6" value that "won't go away"?

BUT YOU'VE STUMBLED ON TO THE "RESET" GOTCHYA IN UNITY!

Just try it with a different variable name...

public Color[] teste;

See?

There it is, working fine. You can set the size dynamically, so long as you never put the size in the code.

Here is the secret:

Unity "holds on to" serialized values in a complicated way.

If you set the size in code even once, Unity "remembers" this even if you subsequently change the code.

There is a way to reset this "inner" value .. look for the famous tiny reset button.

It is attached to the tiny Cog symbol.

The critical rule to remember is this:

NEVER, EVER, HAVE A DEFAULT VALUE IN CODE FOR PUBLIC VARIABLES IN UNITY!!

public float x;  // do this

public float x=2f;  // generally NEVER DO THIS

While you're at it, here's an incredibly handy trick. Try this ...

[Header("How good is this?")]
public float x;

Here's an even cooler one! try it!

[Range(2f,4f)]
public float x;
