The particle viewer can be accessed from the main editor menu (when within a mod, press Tab to open the editor), then click on the text at the top. The menu entry is near the bottom.
Warning: Save your map before you enter the particle viewer! The particle viewer unloads the current map and you will lose changes if you don't save!
Limitations
The particle viewer has no user interface and is entirely controlled via hotkeys. There is no editing functionality -- to edit particles, use a text editor. The mouse cursor is invisible, too.
Some particles are attracted by the mouse cursor or Naija or interact with the environment in some way. Neither of this works in the viewer. Particles that are attracted to something may show weird behavior like zooming off into a corner.
Key bindings
- F1 - Load particle. Enter a particle name, press return to load it (e.g. awesometrail).
- F5 - Reload all partcicle definitions, including the active particle. Restart the active particle. Useful when you have just edited something in the particle definition and want to test the change.
- F9 - Toggle an eel that will follow the mouse, and a black box rotating in a circle?
- Left click - Enable particle spawn (either one-off or continuously, depending on the emitter). The particle emitter will stick to the (invisible) mouse cursor.
- Right click - Disable particle spawn and kill all particles.
- Esc - Close and go back to map
