Question

if (controlsRef !== undefined && controlsRef.current !== undefined) {
    controlsRef!.current!.target = ...
    // Errors with target does not exist on type 'never'
}

useFrame(() => controlsRef.current && controlsRef?.current?.update());
// Errors with update does not exist on type 'never'

调用m.cos时需要使用括号。您的方法调用应如下所示：
