[ad_1] Your getter/setter of objects in your pool manager should not instantiate or destroy gamobjects, but enable and disable them. That is the purpose of pooling. It makes more sense to EnQueue/deQueue them and activate/deactivate like this. private Queue<GameObject> objPool; private Queue<GameObject> activeObj; //get from pool public GameObject GetObjFromPool(Vector3 newPosition, Quaternion newRotation) { GameObject newObject … Read more

[Solved] Compile time Restricted Templates without use of boost

[ad_1] You are missing some typenames and have the class template Move definition repeated three times. Th below code works: #include <iostream> #include <type_traits> using namespace std; template <typename T> class remove_all_pointers{ public: typedef T type; }; template <typename T> class remove_all_pointers<T*>{ public: typedef typename remove_all_pointers<T>::type type; }; template <typename T> class remove_all_pointers<T* const>{ public: … Read more

[ad_1] Your class ‘ZillowListingConnections’ should be – [XmlRoot(ElementName = “ListingConnections”)] public class ListingConnections { [XmlElement(ElementName = “MlsIdentifier”)] public string MlsIdentifier { get; set; } [XmlElement(ElementName = “ListingId”)] public List<string> ListingId { get; set; } } Sample Code public static void Main(string[] args) { var listingConnections = new ListingConnections(); listingConnections.MlsIdentifier = “test”; var ListingIds = new … Read more

[Solved] How to change loop of nested lists linq

by

[ad_1] Avoiding the foreach will lose a small amount of performance and make the code harder to follow, but based on your (probably wrong) question, here is the equivalent LINQ: var ans = listL1.elements.SelectMany(level1 => level1.elements.SelectMany(level2 => listL2.elements.Select(level3 => new Level() { itemFromLevel1 = level1, itemFromLevel2 = level2, itemFromLevel3 = level3}))).ToList(); 2 [ad_2] solved How … Read more

[Solved] Foreach on Json based on value [closed]

by

[ad_1] Here is a crude example, that uses the Newtonsoft.Json nuget package, you can work from and use as inspiration perhaps. It groups by table name and then gets the list for each one. You may want to do it differently I’m not sure. var o = JsonConvert.DeserializeObject<root>(json); var groups = o.tabla.GroupBy(t => t.nombretabla); foreach … Read more

[Solved] Find missing int values from over two or more different dynamic arrays [closed]

by

[ad_1] You can use standard algorithms i.e. : #include <iostream> #include <algorithm> int main() { int array_1[10] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}; int array_2[9] = {0, 3, 4, 6, 7, 2, 9, 8, 5}; int* missingValPtr = std::find_if(std::begin(array_1), std::end(array_1), [&](int arr1Val){ return std::none_of(std::begin(array_2), std::end(array_2), [&](int arr2Val) { return arr1Val … Read more

[ad_1] You can check out this tutorial: http://www.codeproject.com/Articles/20286/GLUI-Window-Template#_articleTop or You can look at mine I did for a school project. https://github.com/sitting-duck/stuff/tree/master/School%20-%20Comp%20Sci/Computer%20Animation%20-%20Fall%202014/Assn1%20-%20Transformations/assn1%20redo/assn1 In this version I just use key bindings to initiate the transformations. Will be easier than making a GUI, so I did that first to learn how to get the transformation code all working, … Read more

[Solved] C++ how to print union name integer [closed]

by

[ad_1] As already mentioned, you cannot somehow “build” some string at run time and use it as variable name. This is a compile time mechanism, and even if this was a compile time problem, it would be a bad idea. You most likely want std::vector<int> nx(someLength); std::vector<int> ny(someLenght); int value = 5; cerr << nx[value] … Read more

[Solved] Unable to assign a value

by

[ad_1] You can simply add using namespace std; before main to make this work. Note: this may cause problems in some situations. Here it’s OK. Moreover, you’re using a wrong header. Use <iostream> instead of <stdio.h>. This will work #include <iostream> using namespace std; int main(int argc, char **argv) { int age1; int age2; cout<<“Enter … Read more

[Solved] Compile time Restricted Templates without use of boost

by

Introduction [ad_1] Compile time restricted templates are a powerful tool for creating efficient and reusable code. They allow developers to create templates that can be used in multiple contexts, while still ensuring that the code is optimized for the specific context in which it is used. This article will discuss how to create compile time … Read more
