How to connect your toy to Risk of Rain 2

RumbleRain and RiskOfRumble are BepInEx mods that drives a toy from Risk of Rain 2 combat events. Setup with ToyControl.

Risk of Rain 2 has a chaotic combat loop and several community plugins that route in-game events to a real toy. RumbleRain and RiskOfRumble are two separate, independently maintained mods. Both use Buttplug.io.

ToyControl is a Buttplug.io server, so the mod connects directly through the Intiface bridge.

What you need

Risk of Rain 2 installed (Steam).
BepInEx for Risk of Rain 2.
RumbleRain or RiskOfRumble.
A toy paired with ToyControl in your browser.
The ToyControl helper app running.
The Intiface bridge turned on in ToyControl's Game Link tab. Quit Intiface Central first if you have it installed; the two cannot share the port.

Step 1: Install BepInEx for RoR2

Use the Thunderstore Mod Manager for the easiest install. It handles BepInEx and mod dependencies automatically.

Step 2: Install the toy mod

In Thunderstore Mod Manager:

Search for RiskOfRumble or RumbleRain.
Click Install.
The manager downloads and places the mod in BepInEx/plugins/.

Step 3: Configure

Launch the game once via Thunderstore. The mod generates a config in BepInEx/config/. Open the relevant .cfg file and set the Buttplug server URL to ToyControl's Intiface bridge URL (visible in ToyControl's Game Link tab).

Step 4: Play

Launch RoR2 normally. The mod loads, connects to ToyControl, and starts firing events:

Taking damage: intensity burst.
Killing an enemy: small response.
Boss kills: stronger response.
Item pickup: brief celebration.
Other events depending on the mod version.

Tuning the feel

RoR2 combat is dense; events fire constantly. Start with Multiplier 0.3-0.5x in ToyControl's bottom bar. Set Speed range max to 60-70.

Troubleshooting

Mod not loading

Make sure your RoR2 version matches what the mod expects. Major RoR2 updates can break BepInEx plugins.
Check Thunderstore for the current "working" version.

Connected but no toy response

Confirm ToyControl is running with the helper app.
Verify the Buttplug URL in the mod config.
Click Test toy in ToyControl.

Multiplayer with toy

If you play co-op, only the host's events fire by default. The mod has options for "event when teammates do X"; check the config.

Privacy

Local only. ToyControl, the mod, and the game all run on your computer.
