[英]Error R3F hooks can only be used within the Canvas component! UseTHREE function
我正在尝试根据鼠标移动旋转立方体,即使 <我的旋转框是画布的子项,我一直在得到:错误 R3F 钩子只能在画布组件中使用! 它可能是由 useTHREE 函数引起的,因为当我删除它时,错误消失了
import { Canvas, useFrame } from "react-three-fiber";
import "./styles.css";
import { useThree } from "@react-three/fiber";
const MyRotatingBox = (props) => {
const mouse = useThree((state) => state.mouse)
const myMesh = React.useRef();
const [onHover, setOnHover] = useState(false);
useFrame(({ clock }) => {
if (onHover) {
myMesh.current.rotation.x += props.mouse.movementX * 0.1;
}
});
return (
<mesh
ref={myMesh}
onPointerOver={(e) => setOnHover(true)}
onPointerOut={(e) => setOnHover(false)}
>
<boxBufferGeometry />
<meshPhongMaterial color="royalblue" />
</mesh>
);
}
export default function App() {
return (
<div className="App">
<Canvas>
<MyRotatingBox />
<ambientLight intensity={0.1} />
<directionalLight />
</Canvas>
</div>
);
}
您正在混合命名空间。 正确的是晚了,@react-three/fiber
