Rocket is an intuitive new way of... bah, whatever. It's a sync-tracker, a tool for synchronizing music and visuals in demoscene productions. It consists of a GUI editor (using Qt5), and an ANSI C library that can either communicate with the editor over a network socket, or play back an exported data-set.

Compile Editor

The Rocket editor uses qmake as a build-system abstraction, which can be used to output Makefiles, Microsoft Visual Studio project files or can be built directly from QtCreator. See the qmake documentation for details.

Compile Example

Rocket contains an example client called example_bass. This is a simple OpenGL, SDL 1.2 and BASS audio library application, that demonstrates how to use the Rocket API.

Before compiling the example, you need to make sure you have recent SDL and BASS libraries and includes.

If you're using Microsoft Visual Studio 2013 or above, this should happen automatically, as these libraries are consumed through NuGet.

The header files and libraries can be installed local to the project by copying all .lib-files to examples/lib/, all .h files to examples/include/, and all .dll files to examples/.

Once the prerequisites are installed, the example can be compiled either by opening examples.sln and selecting Build -> Build Solution from Visual Studio 2008 or 2013, or by doing make examples/example_bass on Unix-based systems.

JavaScript

Thanks to the excellent work of mog, there's now JavaScript support. Have a look at js/README.md for more information.

GameCube, Wii

Rocket should work out-of-the-box using devkitPPC. However, before calling sync_create_device, you should init the FAT filesystem and the network interface, eg. by calling respectively fatInitDefault and if_config. Make sure DNS is also set up correctly when testing on real hardware.

Using the editor

The Rocket editor is laid out like a music-tracker; tracks (or columns) and rows. Each track represents a separate "variable" in the demo, over the entire time-domain of the demo. Each row represents a specific point in time, and consists of a set of key frames. The key frames are interpolated over time according to their interpolation modes.

Interpolation modes

Each key frame has an interpolation mode associated with it, and that interpolation mode is valid until the next key frame is reached. The different interpolation modes are the following:

  • Step : This is the simplest mode, and always returns the key's value.
  • Linear : This does a linear interpolation between the current and the next key's values.
  • Smooth : This interpolates in a smooth fashion, the exact function is what is usually called "smoothstep". Do not confuse this mode with splines; this only interpolates smoothly between two different values, it does not try to calculate tangents or any such things.
  • Ramp : This is similar to "Linear", but additionally applies an exponentiation of the interpolation factor.

Keyboard shortcuts

Some of the Rocket editor's features are available through the menu and some keyboard shortcut. Here's a list of the supported keyboard shortcuts:

Shortcut Action
Up/Down/Left/Right Move cursor
PgUp/PgDn Move cursor 16 rows up/down
Home/End Move cursor to begining/end
Ctrl+Left/Right Move track
Enter Enter key frame value

k Toggle row-bookmark
Alt+PgUp/PgDn Go to prev/next row-bookmark
Space Pause/Resume demo
Shift+Up/Down/Left/Right Select
Ctrl+C Copy
Ctrl+V Paste
Ctrl+Z Undo
Shift+Ctrl+Z Redo
Ctrl+B Bias key frames
Shift+Ctrl+Up/Down Quick-bias by +/- 0.1
