[Warning] missing initializer for member 'sk::timedamage' [-Wmissing-field-initializers]

这个警告表示在定义结构体或类时,某个成员变量没有被初始化。这可能会导致程序在访问这个未初始化的成员变量时出现未定义的行为。
解决这个问题有两种方法:
1. 在定义结构体或类时,为所有成员变量都提供初始值,例如:
```
struct MyStruct {
int x = 0;
float y = 0.0f;
char z = 'a';
// ...
};
```
2. 在代码中使用成员初始化列表来为成员变量进行初始化,例如:
```
struct MyStruct {
int x;
float y;
char z;
MyStruct() : x(0), y(0.0f), z('a') {}
// ...
};
```
在上面的代码中,MyStruct() 是默认构造函数,使用了成员初始化列表来初始化成员变量 x、y 和 z。

warning: missing braces around initializer [-Wmissing-braces]
This warning usually occurs when defining an array or structure without using braces to enclose the initializer values. It is important to use braces to ensure that the initializer values are properly enclosed and to avoid potential errors or unexpected behavior.
For example, consider the following code:
```
int myArray[3] = 1, 2, 3;
```
This code will produce the warning "missing braces around initializer" because the initializer values are not enclosed in braces. To fix the issue, the code should be written as follows:
```
int myArray[3] = {1, 2, 3};
```
In this code, the initializer values are enclosed in braces, which ensures that they are properly initialized and avoids any potential errors or unexpected behavior.

这是一个编译警告,意思是在第83行的代码中,一个初始化器缺少了大括号。这可能会导致代码在某些情况下出现意外行为。为了解决这个警告,你需要添加缺少的大括号来确保初始化器的正确性。例如,如果你有一个结构体变量的初始化器,应该像这样写:
```
struct my_struct {
int foo;
int bar;
};
struct my_struct my_var = {
.foo = 1,
.bar = 2,
};
```
如果你缺少了大括号,会变成这样:
```
struct my_struct my_var =
.foo = 1,
.bar = 2;
```
这是不正确的,应该改为:
```
struct my_struct my_var = {
.foo = 1,
.bar = 2,
};
```
