Sprite Animation w/ Cocos2dx

For preparing the necessary technology with animation in cocos2dx, I made a really simple repo that includes a straightforward animation demo with cocos2dx.

Here is the development env:

Visual Studio 2017 Community

cocos2d-x-3.17.2

For the sprite sheet and the assets, I used TexturePacker v5.0.9 Free version and bought assets from HumbleBundle. Based on those tools and resources, I made a simple sprite sheet[1] that includes an IDLE animation for a fighter.

Figure 1, the result of the sprite sheet

After that, I placed the sprite sheet to the resource folder inside the cocos2dx project folder.

Okay, all the assets and foundation are ready. Let’s code!

1.Load the plist (It comes with the sprite sheet when you publish a sprite sheet via TexturePacker)

// Load spritesheet info from plist SpriteFrameCache::getInstance()->addSpriteFramesWithFile("fighter.plist");

2.Create a extractor function to get all sprite frames for one animation

Vector idleFrames = this->GetAnimation( "idle_%d.png", 14 ); // ... // Get all sprite frames from the spritesheet based on a string format. // Need to pass the string format and how many frames that this animation has. // It returns a vector of SpriteFrame*. Vector HelloWorld::GetAnimation(const char* pchFormat, int iCount) { auto spriteCache = SpriteFrameCache::getInstance(); Vector animFrames; char str[100]; for (int i = 1; i <= iCount; i++) { // format string from parameters sprintf(str, pchFormat, i); printf(str); // add sprite to animFrames animFrames.pushBack(spriteCache->getSpriteFrameByName(str)); } return animFrames; }

3.Use the first item inside the vector and place it to the centre of the scene

// Set the default sprite frame to the first sprite frame in the vector Sprite* fighterIdleSprite = Sprite::createWithSpriteFrame( idleFrames.front() ); // Align sprite to center fighterIdleSprite->setPosition( origin.x + visibleSize.width / 2, origin.y + visibleSize.height / 2 ); // Add node to scene this->addChild( fighterIdleSprite );

4.Create animation object and apply update frequency

// Create animation by vector of sprite frames and the update fequency Animation* idleAnim = Animation::createWithSpriteFrames( idleFrames, 1.0f / 14 );

5.Apply it to the sprite by running runAction

// Apply animation to sprite by using runAction fighterIdleSprite->runAction( RepeatForever::create( Animate::create( idleAnim ) ) );

Result

Here is the repo link: Github Repo

The most important cpp file will be: HelloWorldScene.cpp Start from Line 105

複数のクラスのメソッドを指定のタイミングで同時に行う【Unity】

こんにちは！お久しぶりです。

「しまだ」です。

久々のブログ投稿になります。

なのでちょっとだけ近況報告をします！

最近は、いろんなゲームイベントに参加しながら東京ゲームショウ アマチュア部門向けのゲームを作っていました。

先日は5/20・5/21の二日間で京都のみやこめっせで行われた

「A 5th of BitSummit」に遊びに行ってきました。

BitSummitには毎年遊びに行っているんですが、今年も面白いゲームが多く展示してあり、二日間会場を動き回りましたw

実際に制作者の方とお話することもでき、刺激を受けることが出来たので、ゲームショウに向けてゲームを作りこんでいきます。

さて、そろそろ本題に入りましょう！

今回の内容はタイトルにもある通り「複数のクラスのメソッドを指定のタイミングで同時に呼ぶ」です！

僕は普段Cocos2d-xを使用してゲームを作っていたのですが、今回のゲームはUnityで制作しています。

Cocos2d-xで制作をしている際、「あるタイミングで異なるクラスのメソッドを一斉に行いたい」という時に「シングルトンのmanagerクラスに、メソッドを受け渡して保存しておく」ことで解決していました。

今回はこれをUnityでも行いたいと思い実装しました。

問題の処理なのですが、Cocos2d-xで行っていた処理はこんな感じでした。

#pragma once #ifndef __Test__TestManager__ #define __Test__TestManager__ #include "cocos2d.h" //シングルトンクラス using namespace cocos2d; using namespace std; class TestManager { public: static TestManager *_instance; static TestManager *getInstance();//インスタンスを取得 bool init(); void update(float delta); void test();//登録した処理を呼ぶ処理 void addFunc(function<void()> func);//処理を登録する処理 private: vector<void()> _testFunc;//メソッド登録用の配列 }; #endif /* defined(__Test__TestManager__) */

.hはこんな感じで

#include "TestManager.h" TestManager *TestManager::_instance; //シングルトンにする TestManager *TestManager::getInstance() { //インスタンスが作られてなかったら作る if (_instance == NULL) { _instance = new TestManager(); _instance->init(); } return _instance; } bool TestManager::init() { // updateが毎フレーム呼ばれるよう登録 Director::getInstance()->getScheduler()->unschedule("TestManagerUpdate", this); function _update = [=](float dt) {this->update(dt); }; Director::getInstance()->getScheduler()->schedule(_update, this, 0.0f, -1, 0, false, "TestManagerUpdate"); _testFunc.clear(); return true; } void TestManager::update(float delta) { } //登録した処理を呼ぶ処理 void TestManager::test() { for (auto func : _testFunc) { func(); } } //処理の登録用メソッド void TestManager::addFunc(function<void()> func) { _testFunc.push_back(func); }

.cppはこんな感じです。

メソッドを登録したいときは、登録したいメソッドを持っている側で

function<void()> func = [=]() { log("test"); }; TestManager::getInstance()->addFunc(func);

のように処理してあげることで登録しています。

function<void()> func = [=]() { 　test(); }; TestManager::getInstance()->addFunc(func);

もちろん、ここで中身にメソッドを入れてあげることで、メソッドの登録もできます。

そして、本題となるこれをUnityで実装した方法なのですが

考え方自体はそのまま使用することができました。

変更するのは、配列とメソッドの引数だけです。

実際のソースはこちらになります。

using System.Collections; using System.Collections.Generic; using UnityEngine; using System; public class TestManager : MonoBehaviour { public static TestManager _instance; //処理を登録するための配列 List<Action> _testFunc = new List(); void Awake() { //インスタンスが作られてなかったら作る if (_instance == null) { _instance = this; _instance.init(); } } //シングルトンにする public static TestManager getInstance() { return _instance; } bool init() { _testFunc.Clear(); return true; } void Start() { } // Update is called once per frame void Update() { } //登録した処理を呼ぶ void test() { for (int i = 0; i < _testFunc.Count; i++) { _testFunc[i](); } } //処理を登録する public void addFunc(Action func) { _testFunc.Add(func); } }

まず初めに、配列を動的に使用したいので、配列ではなくListを使用します。

Listを使用するためには、ソースコードの一番上に

using System.Collections.Generic;

を入れてあげる必要があります。

そして、Listの宣言方法ですが、

//List<型> 変数名 = new List<型>(); List<int> _test = new List<int>();

という形になります。

そして、登録するためのメソッドの型ですが、調べたところAction型を使用することで解決できました。

Action型を使用するためにも、ソースコードの一番上に

using System;

を入れてあげます。

そして、Action型を持ったListを作成します。

List<Action> _test = new List<Action>();

次に、Listにメソッドを登録するためのメソッドを作成します。

//処理を登録する public void addFunc(Action func) { _testFunc.Add(func); }

こちらにも、同じようにAction型を引数にしておきます。

Listに要素を追加する際には、Addを使用します。

これで、メソッドを登録する準備ができました。

あとは、登録したいメソッドを持��ている側のクラスで登録します。

Action func = delegate { test(); }; TestManager.getInstance().addFunc(func);

このように宣言することで、メソッドをAction型で受け渡せるようにします。

あとは、Manager側のクラスで

//登録した処理を呼ぶ void test() { for (int i = 0; i < _testFunc.Count; i++) { _testFunc[i](); } }

このメソッドを実行したいタイミングに合わせて呼んであげれば、指定のタイミングで異なるクラスの処理を一斉に呼び出すことができます。

僕は、Manager側にカウンタを作ることで、数フレーム毎に呼ばれる処理などに使用しています。

これで、今回のブログの内容は終了です！

ありがとうございました！

Enter Booty Quest

After some months soft launched in a small number of countries it seems that the world release date has arrived, and I can finally share the game I worked in during my time in Outplay: 

[kutumbh-blog]

It has been always a challenge to integrate push notification to a project which is not written in native language. Cocos2dx projects which is based on c++ also has to face the same challenge.

COCOS2D X

What is Cocos2d x ?

Cocos2d-x is an open source cross-platform game framework written in C++/Javascript/Lua. It can be used to build games, apps and other interactive programs. Cocos2d contains many branches with the best known being Cocos2d-objc, Cocos2d-x, Cocos2d-html5 and Cocos2d-XNA. There are some independent editors in the cocos2d community, such as those contributing in the areas of SpriteSheet editing, particle editing, font editing and Tilemap editing as well as world editors including SpriteBuilder and CocoStudio.

Features of Cocos2d: Sprites and scenes

All versions of Cocos2d work using the basic primitive known as a sprite. A sprite can be thought of as a simple 2D image, but can also be a container for other sprites. In Cocos2D, sprites are arranged together to form a scene, like a game level or a menu. Sprites can be manipulated in code based on events or actions or as part of animations. The sprites can be moved, rotated, scaled, have their image changed, etc.

GUI

Cocos2D provides primitives to representing common GUI elements in your game scene. This includes things like text boxes, labels, menus, buttons, and other common elements.

Animation

Cocos2D provides basic animation primitives that can work on sprites using a set of actions and timers. They can be chained and composed together to form more complex animations. Most Cocos2D implementations let you manipulate the size, scale, position, and other effects of the sprite. Some versions of Cocos2D let you also animate particle effects, image filtering effects via shaders (warp, ripple, etc.)

Cross Platform

Publish from a single code base to mobile, desktop, web, and console. Cocos2d-x allows developers to focus on building cutting-edge games while it takes care of the heavy lifting on the back-end.

Lightweight & Fast Running

Completely written in C++, the core engine has the smallest footprint, yet the fastest speed of any other game engine, and is optimized for running on all kinds of the devices including low-end Android systems.

Simple & Easy to Learn APIs

Cocos2d-x APIs are created and maintained by industry legend Ricardo Quesada who created the original, super popular Objective-C version. There is a variety of documents, tutorials, and demos to get you started, so dive in and experience Cocos2d-x first hand.

As we can see from above key points cocos2d is very handy software for game devlopment, and the sprites sheets which cocos2d makes that can be editable by using Plist software.

Knockout 2: Wrath of the Karen is hoping to solve problems with fighting on Linux

Knockout 2: Wrath of the Karen boxing action game sees hope for Linux port with Mac and Windows PC. All due to further details from developer ExceptioNULL Games. Due to making its way onto Steam Early Access. Indie game studio ExceptioNULL Games just announced Knockout 2: Wrath of the Karen. Due to have you fight for your honor in a hilarious alternate reality. One where all problems are solved through boxing. Billed as a spiritual successor to Nintendo's Punch-Out!! games. Knockout 2 pits you against the worst of society. So the only way out is with your fists. Got cut in line at the grocery store? That's a boxing match. Offended a scam caller? That's a boxing match, too. In fact, all laws, court cases, and skimping out on sandwich toppings are resolved through combat. Doing so in a world where civil discourse has failed.

On top of that, there is hope for Knockout 2 on Linux:

We've switched from Cocos2dx to Unity for this sequel, making the port work easier. There's at least one other Linux gamer in our Discord asking the same thing. The biggest hurdle we face with committing to Linux is the lack of testing. If Knockout 2 fans can help us put a few hours behind a Linux build once we go Early Access, it would justify the effort.

Thanks to the ExceptioNULL email reply, there is hope for Linux. Since the studio has now switched to Unity 3D. Plus they will need Linux testers when the game hits Early Access for 3 - 6 months. At this time, it shouldn't be difficult to round up some Linux testers. Knockout 2 builds upon the exciting gameplay of its predecessor. ExceptioNULL Games once again flings their sharp comedic storytelling in all directions. As a result, no one is safe from the splashback. Knockout 2 leaves behind the electoral politics of the first game and takes on society at large. Then leading you on a road trip across America and around the world. Mete out pugilistic justice through fast-paced rhythm boxing gameplay. Including tight controls and charming graphics. Tricky opponents comewith a mix of traditional and modern animation. Since each has a puzzle to pick apart and solve before expertly playing them like a fiddle. Knockout 2: Wrath of the Karen boxing action game is releasing on Steam Early Access in 2024. So be sure to Wishlist the game. Due to making its way onto Linux with Mac and Windows PC. Stay turned, there is more to come.

Something I was missing in the previous version on #cocos2dx was to create maps at runtime. Now, with #unity3d, using Voronoi diagrams I'm able to create endless maps variations. super cool!
