Snippet showing how to read user value via C++ MODO SDK.

getUserValue.cpp

/* To read user value we spawn a new user value command.
 * Then, we are using the attributes interface set to the command
 * to set command's first argument to the name of the user value
 * that we want to read.
 * Next we obtain the index the of "value" argument so we can query
 * command for this argument and store user value's value in the value array.
 * The final step is to read the value from value array and put it
 * inside value int variable. In this case we know it's an int
 * so we go with GetInt() directly. If you do not know value's type
 * you can get it using .Type() method on the ValueArray interface.
 *
 * Similar code can be used to query any command. Spawn command first,
 * then set all the arguments that need to be set for the query to return
 * result you are after and finally query the command for the value.
