Essential Roll20 FX Commands
Use core roll20 fx commands to add visual feedback during gameplay. Prefix most chat commands with /fx to instantly trigger effects on the active scene.
Common options include sparkles, fire, smoke, lightning, and explosion graphics. You can target specific tokens or apply effects to the entire viewport.
These commands work alongside Roll20 macros, making it easy to bind complex sequences to a single button press.
Customizing FX with Parameters
Adjusting Duration and Scale
Many roll20 fx commands accept optional parameters for duration, size, and repetition. Adding numbers after the base command can control how long the effect lasts.
For example, appending values can stretch fire effects across larger areas or shorten sparkles to a single burst.
Targeting Specific Tokens
You can limit effects to selected characters or monsters by specifying token IDs. This precision keeps visual clutter low during busy encounters.
Integrating FX into Macros and Routines
Building Advanced Macro Chains
Combine roll20 fx commands with chat commands and API calls inside macros. Sequence effects to match the pacing of combat or scripted events.
Use delays to sync lighting changes with narrative beats, creating a more cinematic experience for the group.
Reusing FX Setups Across Campaigns
Save favorite command bundles as macro buttons for quick access. Label them clearly so you can summon the right ambiance in different scenes.
Performance and Compatibility Considerations
Complex roll20 fx commands can impact browser performance if overused on crowded maps. Limit simultaneous heavy effects during large combat scenes.
Test new effects in a private session before presenting them to players to ensure compatibility with your device and client.
