C# InvokeRepeating, has some invalid arguments

In a C# script I have this...

Code (csharp):

1.  
2. InvokeRepeating("slowTween", 0.1, tSTF);
3.  

where the tSTF is a float, however I am told that this argument list has some invalid elements.

 

You need to use

Code (csharp):

1. InvokeRepeating("slowTween", 0.1f, tSTF);

The "f" indicates that the value is a float rather than a double.

 

thanks.
