The following actions are only available when optional Storyboard plugins has been loaded.
Cause a Lua script function to execute.
libgre-plugin-lua.so
The name of the Lua function to invoke
Additional arguments can be passed to the function by providing additional key/value pairs to the action. The key/value pairs are provided to the Lua function as values in the argument table.
For example to call the Lua function myfunction
with an extra argument, firstargument, that
corresponds to the value of the application variable
myvar you would simply add a new entry to the
parameter list.
The corresponding call to the Lua function would fill the entry into the argument table such that:
function myfunction(mapargs)
print("The value is: " .. tostring(mapargs.firstargument))
end
would print out the value of ${app:myvar}.
Start an animation. Animations are started based on their name. Each animation can have an optional identifier (id) which is used to ensure that animations run in an exclusive manner. If an existing animation is running that uses the same identifier, then that animation is stopped before this animation is started. The data argument is as follows:
libgre-plugin-animation.so
The animation name to start
An optional instance id to be associated with the animation. Animation identifiers can be used with different animations to ensure that only one animation of the set is running at a time.
When the animation stops it will emit a notification event in the form of
gre.animate.complete.[name]. This event will be delivered within the context of the gra.animate action
and will be delivered to the object which invoked the action.
Stop an animation. If you stop an animation only by name then all running animations with that name will stop and emit a complete event. If you stop an animation by id then only that specific animation will stop and emit a complete event. The data argument is as follows:
libgre-plugin-animation.so
The animation name to stop
An optional instance id associated with the name
When the animation stops it will emit a notification event in the form of
gre.animate.complete.[name]
Start or stop the asynchronous playback of a WAV audio file. The data argument is as follows:
libgre-plugin-audio.so
A filename to play, or empty to stop the current playback.
Send a new event over a Storyboard IO channel.
libgre-plugin-greio.so
Storyboard IO channel name to send the event to (required)
The name of the event to generate (required)
The target of the event to generate (optional)
The format of the event data (optional)
The data payload for the event
Control the capture of performance data
libgre-plugin-logger.so
Turn off (0) or on (1) performance data capture
In order for this action to be used, the
libgre-plugin-logger.so must have been started with
performance logging enabled, but not necessarily to have it start capturing
the performance data. For example sbengine -ologger,perf=0 will
enable performance logging but not start capturing events at startup while
sbengine -ologging,perf=1 will enable performance logging
and immediately start capturing events.
Redirect all events to another Storyboard IO channel.
libgre-plugin-redirect.so
Storyboard IO channel name to send the events to

Dump the contents of the screen to an image file.
libgre-plugin-screen-dump.so
The filename of the image file to create. The directory path to the filename must exist and the filename will be overwritten if it is. The filename must end with either a .bmp extension to generate BMP formatted images or .tga to generate TGA formatted images
Start, stop and control a timer.
libgre-plugin-timer.so
The name to use to identify this timer (required)
The time delay in milliseconds relative to the action invocation. Specify a value of 0 to stop an existing timer.
The number of milliseconds to delay after the timer first fires, used to provide a stable repeat timer. Specify 0 for a one shot timer.
The number of times that the timer should repeat before automatically stopping, assuming that the timer is not a one shot timer. Specify -1 to allow an unlimited number of repeat firings
rtime must be specified and a value of 0 for rtime and repeat indicates that the timer should stop firing.
For example, to start a timer that fires in 1s from the event and then every 500ms afterwards:
<action ... type="timer"
data="name=MyTimer,rtime=1000,repeat=500" />
Then to stop the timer:
<action ... type="timer" data="name=MyTimer,rtime=0,repeat=0"
/>
An event will be generated each time that the timer fires and will be named timer.<name> so for the examples above, the event would be generated would be timer.MyTimer.
The following actions can be used to control the media playback. Note that all actions take a “channel_name” argument. This is used to target a specific playback channel. For example if a video is started with “gra.media.new.video” with “channel_name=video1” then any subsequent action which wants to act on this video, such as play/pause, must set the channel “video1”.
