CUEP

There is a useful mod called UnityExplorerPlus (find it there), which is made for HollowKnight. This mod port some of it's features to silksong and might be helpful for modding developers.

Additionally, I also referenced FSMExpress to implement an in-game FSM viewer in this mod, which can help you know exactly how the FSM runs.

Implemented features

• Show Fsm Info in the list view.
• Add Collider/Enemy/Renderer Inspect.
• Show and Dump extracted sprite and tk2dsprite.
• Show shader info in inspector of Material.
• In-game Fsm viewer.
• ...

For FSM Viewer

• When you inspect a PlayMakerFSM, a button labeled "Open Fsm Inspector" will appear in the upper-right corner. Click it to open the viewer.
• The State, Event, and Variables pages function identically to their counterparts in FSMExpress.
• The Operations page displays the currently selected State and Transition. With "Recording" enabled, it can also log the FSM's transition process.
• Occasionally, connection lines may appear in incorrect positions. Reopening the viewer typically resolves this issue. If you know how to fix it permanently, feel free to raise a Pull Request.
