Unity3d Password box cannot recognize the problem of char

When I wrote the Password box today, I used the help method to parse the information:Unexpected CHAR :'''. Think twice about it.

This is an example of help:

VaR Passwordtoedit =   " My password " ;

Function Ongui () {
//Make a password field that modifies passwordtoedit.
Passwordtoedit=Guilayout. passwordfield (passwordtoedit,'*',25);
}

 

It is estimated that this is a problem of unity3d itself. It does not recognize the char method represented by the simple argument. After thinking down, I think of a new method to solve this problem. The token generation is as follows:

VaR Passwordtoedit =   " My password " ;

Function Ongui () {
//Make a password field that modifies passwordtoedit.
Passwordtoedit=Guilayout. passwordfield (passwordtoedit ,"*"[0],25);
}
