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 base don their name. Each animation can have an optional unique id which can later be used to stop a particular animation. 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
When the animation stops it will emit a notification event in the form of
gre.animate.complete.[name]
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 anaimation by id then only animations with that id 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 perfomance 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
Causes a screen transition to occur by fading the old screen into the new one.
libgre-plugin-screen-path.so
The screen to transition to
Defines how the alpha values will change
| linear |
| easein |
| easeout |
| easeinout |
| bounce |
Number of frames per second
Length of the transition in milliseconds
The direction to transition from
| left |
| right |
| top |
| bottom |
Causes a screen transition to occur by scaling the old screen into the new one.
libgre-plugin-screen-scale.so
The screen to transition to
Defines how the alpha values will change
| linear |
| easein |
| easeout |
| easeinout |
| bounce |
Number of frames per second
Length of the transition in milliseconds
The layers to transition, all of the layers or just the layers that are different between source and destination.
| all |
| delta |
Causes a screen transition to occur by using 3D to switch the old screen into the new one.
libgre-plugin-screen-3d.so
Causes a screen transition to occur by using 3D to rotate the old screen in the x-axis into the new one.
libgre-plugin-screen-3d.so
Causes a screen transition to occur by using 3D to switch the old screen into the new one.
libgre-plugin-screen-3d.so
Causes a screen transition to occur by using 3D to switch the old screen into the new one using a door opening animation.
libgre-plugin-screen-3d.so
Causes a screen transition to occur by using 3D to switch the old screen into the new one by tipping the display forward.
libgre-plugin-screen-3d.so
Causes a screen transition to occur by using 3D to switch the old screen into the new one using a cube animation.
libgre-plugin-screen-3d.so
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. One of rtime or atime values are required. Specify a value of 0 to stop an existing timer.
The time delay in as an absolute value as a YY:MM:DD:HH:mm:ss:ms string format. One of rtime or atime values are required.
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
One of rtime or atime must be specified and a value of 0 for rtime/atime 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.
