Required Methods

unsafe fn get_node_as<'a, T>(&self, path: P) -> Option<TRef<'a, T>>where
    T: SubClass<Node>,

Convenience method to obtain a reference to a node at path relative to self, and cast it to the desired type. Returns None if the node does not exist or is not of the correct type.

Safety

This method accesses the scene tree. As a result, any calls to this function must follow the official thread-safety guidelines. assume_safe invariants must be observed for the resulting node during 'a, if any.

Provided Methods

unsafe fn get_node_as_instance<'a, T>(&self, path: P) -> Option<TInstance<'a, T>>where
    T: NativeClass,
    T::Base: SubClass<Node>,

Convenience method to obtain a reference to a node at path relative to self, and cast it to an instance of the desired NativeClass type. Returns None if the node does not exist or is not of the correct type.

Safety

This method accesses the scene tree. As a result, any calls to this function must follow the official thread-safety guidelines. assume_safe invariants must be observed for the resulting node during 'a, if any.
