Hi Unity Answers,
Out of some weird circumstances, I need to programatically read all the values of playerprefs stored in the registry, and not simply use PlayerPrefs.GetFloat(). When using Regedit I saw that the float registry keys value was `REG_DWORD` and not a `REG_QWORD` or `REG_BINARY`. Also the value is listed as "(invalid DWORD (32-bit) value)". When you view the hex-data stored it seems to have a value, but it does not correlate to the actual value stored in unity.
When I read the value stored at the keys, I get completely different values. For instance I have a float stored in unity with a value of 1, the hex value shown in Regedit is `00 00 00 00 00 00 F0 3F` and the value converted to a float is `4.60718242E+18`. The strange thing is that unity still can read and process these values correctly. The function I am using to process the reg values is bellow:
public void ReadRegistryKeyValues()
{
RegistryKey rk = Registry.LocalMachine.OpenSubKey("Software\\" + PlayerSettings.companyName +"\\" + PlayerSettings.productName , false);
foreach (string key in rk.GetValueNames())
{
var currentKey = rk.GetValue(key);
if(currentKey != null)
{
if(currentKey.GetType().Name == "Int32")
{
int r = Convert.ToInt32(currentKey);
}
if (currentKey.GetType().Name == "Int64")
{
float r = Convert.ToInt64(currentKey);
}
if (currentKey.GetType().Name == "String")
{
string r = currentKey.ToString();
}
}
}
}
Does anyone know how to read the invalid DWORD correctly in c#? Or does anyone know of a Way to force C# to read this key as QWORD? Does a Unity Software Engineer want to reveal the process they use to read these invalid reg keys?
