switchto statement

The switchto statement is similar to the Switch statement, except that the case values are implied. This is useful if you’re frequently inserting and removing cases from a changeState method, since you won’t need to update the case values.

syntax:

(switchto switch_expression
        (
                code_block_1
                code_block_2
                ...
        )
        (
                code_block_1
                code_block_2
                ...
        )
        .
        .
        .
        (
                code_block_1
                code_block_2
                ...
        )
)

Example using the switchto statement:

(switchto state
        (
                (= seconds 2) ; Wait two seconds
        )
        (
                (client setMotion: MoveTo 100 120 self) ; Move to (100, 120) then go to next state
        )
        (
                (drumRoll play:)        ; play the drum rool
                (= seconds 3)
        )
        (
                (drumRool stop:)        ; and stop after three seconds.
        )
)
