# Decorating Commands

Although the different commands Joos provides are very useful, they can sometimes be cumbersome to put together to form new commands. Take this example:

new SequentialCommand(
        myCommand,
        new WaitCommand(4)
);

SequentialCommand(
    myCommand,
    WaitCommand(4.0)
)

It adds a delay of 4 seconds after myCommand finishes. This is not difficult to write, but the syntax can be condensed greatly:

myCommand.wait(4.0);

myCommand wait 4.0

Here are some of the shortcuts you can use to add functionality to your commands:

//Original
new SequentialCommand(
        myCommand,
        new WaitCommand(1.0)
);

//Shortcut
myCommand.wait(1.0);

//Original
SequentialCommand(
    myCommand,
    WaitCommand(1.0)
)

//Shortcut
myCommand.wait(1.0)

//Original
new SequentialCommand(myCommand, otherCommand);

new RaceCommand(myCommand, otherCommand);

new ParallelCommand(myCommand, otherCommand);

//Shortcut
myCommand.then(otherCommand);

myCommand.race(otherCommand);

myCommand.and(otherCommand);

//Original
SequentialCommand(myCommand, otherCommand)

RaceCommand(myCommand, otherCommand)

ParallelCommand(myCommand, otherCommand)

//Shortcut
myCommand.then(otherCommand)

myCommand.race(otherCommand)

myCommand.and(otherCommand)

For the rest of the ways you can decorate commands, see the Kotlin docs or Java docs.
