【C++】指针引发的bug

如果你要从配置里面取一个属性，需要修改这个属性，注意不要把配置的属性修改掉了。取的是配置的指针属性，需要弄个临时属性来修改计算。

	int nLuckValue = WingsAngelCfg.m_Config.nWing[nLevel].nLuck;
	double percentage = (double)nLuckPoint/nLuckValue;
	nCount = WingsAngelCfg.m_Config.nWing[nLevel].nCount;
	if(nCount == 0)
		return calc;
	GAMEATTR* tmpValueProp = WingsAngelCfg.m_Config.nWing[nLevel].PropList;
	if(tmpValueProp == NULL)
		return calc;
	for (int i = 0; i < nCount; i++)
	{
		//if(tmpValueProp[i].reserve[0] == 0)
		{
			GAMEATTR Prop;
			INT_PTR nValue = tmpValueProp[i].value.nValue * percentage;
			if(nValue <1)
			{
				nValue = 1;
			}
			Prop.type = tmpValueProp->type;
			Prop.value.nValue = nValue;	
			calc << Prop;
		}
	}
