Setting default values for user command parameters

Hello,

Is there a way to set default values for the parameters passed into a user command?

The C++ syntaxis doesn't seem to work. I would expect to be able to define it similarly. Am I just missing something trivial?

Thanks in advance!!

For example: I would like to define a function as below. But if I call this with one parameter only, I get the error that I am not passing enough parameters.

Hi Lucas,

In the parameters field, you can indicate that the parameter is optional as follows:

(double inputOne[, int inputTwo])

Then in the code, you can check the number of parameters using the parqty function and set the default if necessary:

int inputTwo = (parqty() >= 2) ? param(2) : 42;

where I have used 42 as the default value to distinguish it from the parameter index (2) in this example.

Perfect, thank you Mischa!
