DAGviz is a game-state viewer/editor for Sly 2 and Sly 3 using memory.js and graphviz. Downloads are available on the Releases tab.
- Explore the DAG and see task connections
- Watch task states update in real-time
- Right-click a task to edit its state
- Export the graph to a DOT language file
- Export the current view to a PNG image
- Plain-english node labels based on task descriptions
- Changes to DAG persist between reloads
Use the scroll wheel to zoom, and click + drag to pan the current view.
Right click a node to see some options such as copying the memory address of the node, change its state, or export the current DAG
git clone https://github.com/theonlyzac/dagviz
npm install # install dependencies
npm start # run the appThen build the exe with npm run-script build.
Make sure PCSX2 is open and Sly 2 or 3 (NTSC) is running. It may take a moment to populate the DAG.
If it says the correct episode in the top-left but you do not see the DAG, it is probably off-screen. Zoom out with the scroll wheel, and/or click+drag to find it.
If it is not detecting that the game is running, uncheck the "Auto-detect build" box and set the game build manually. Please submit an issue saying which build and which map you were playing on.
Each node corresponds to a task, and tasks are color-coded by their state:
| Value | State | Color |
|---|---|---|
| 0 | Unavailable | Red |
| 1 | Available | Green |
| 2 | Complete | Blue |
| 3 | Final | Gray |
By default, each node displays it's unique ID. You can change this using the "Nodes display" option. Nodes have plain-english names in the game's code, but there is no known method to extract those from the game, so the ID is the next best thing.
Diamond-shaped tasks have checkpoints. When you die, you respawn at the last active checkpoint.
Each box/cluster of tasks is a "mission". Once you complete the exit task for a mission, all the Complete tasks in that job get set to Final.
