Starting with a parent object, get the first Child Object by name.

orxOBJECT* GetChildObjectByName(orxOBJECT *parentObject, orxSTRING childName) {
	for (orxOBJECT *pstChild = orxObject_GetOwnedChild(parentObject);
		pstChild;
		pstChild = orxObject_GetOwnedSibling(pstChild))
		{
			const orxSTRING name = orxObject_GetName(pstChild);
			if (orxString_Compare(name, childName) == 0) {
				return pstChild;
			}
		}
 
	return orxNULL;
}
