Description
Description
I'm experiencing problems with data binding in rive-react-native v9.3.1. The useRiveNumber hook isn't successfully updating values in my Rive animation.
Environment
- rive-react-native version: 9.3.1
- React Native version: 0.76.9
- Platform: [Both]
Reproduction Steps
- Set up a basic Rive component with the rewards.riv file
- Attempt to use useRiveNumber to update the 'Energy_Bar/Lives' value
- Press button to trigger the update
- Observe that the animation doesn't reflect the change
Expected Behavior
The Lives counter in the animation should update to the new value (10) when the button is pressed.
Actual Behavior
- The Lives counter doesn't update
- console.log shows {lives: null, setLives: [Function]}
- No errors are displayed
Code Example
import React from 'react'
import { View, useWindowDimensions, Button } from 'react-native'
import Rive, {
Fit,
useRive,
AutoBind,
RNRiveErrorType,
RNRiveError,
useRiveNumber,
} from 'rive-react-native'
export const RiveTestView = () => {
const { width } = useWindowDimensions()
const [setRiveRef, riveRef] = useRive()
let [lives, setLives] = useRiveNumber(riveRef, 'Energy_Bar/Lives')
const onChangeLives = () => {
if(!setLives) {
return
}
setLives(10)
}
console.log({lives, setLives})
return (
<View >
<View style={{ width, height: '100%' }}>
<Button title="Update Rive Text" onPress={onChangeLives} />
<Rive
ref={setRiveRef}
fit={Fit.Layout}
layoutScaleFactor={1}
autoplay={true}
dataBinding={AutoBind(true)}
stateMachineName={'State Machine 1'}
source={require('./assets/rewards.riv')}
onError={(riveError: RNRiveError) => {
switch (riveError.type) {
case RNRiveErrorType.DataBindingError: {
console.error(`${riveError.message}`)
return
}
default:
console.error('Unhandled error')
return
}
}}
/>
</View>
</View>
)
}

Research direction
Start by reproducing the example with the provided rewards.riv asset, React Native 0.76.9, and rive-react-native 9.3.1. Trace the useRiveNumber hook and its data-binding entry point, then verify that the Energy_Bar/Lives value changes from null and updates the animation to 10 when the button is pressed.
