Cocos2d-x-samples

[TOC]

Contains different samples that show how to use Cocos2d-x v3.2 with 3rd party libraries:

Running the samples

Download

$ git clone https://github.com/cocos2d/cocos2d-x-samples.git
$ cd cocos2d-x-samples
$ python download-engine.py

Running

Once the samples were downloaded just go any sample, and open the project. eg:

$ cd cocos2d-x-samples/samples/LiquidFun-Testbed/proj.ios_mac
$ open LiquidFun-Testbed.xcodeproj/

Available samples:

LiquidFun

Based on Box2d, LiquidFun features particle-based fluid simulation. Game developers can use it for new game mechanics and add realistic physics to game play. Designers can use the library to create beautiful fluid interactive experiences.

We provide 2 samples:

LiquidFun - Testbed

The Testbed that comes with LiquidFun, adapted for cocos2d-x.

Supported platforms:

• iOS
• Mac
• Win32

LiquidFun - EyeCandy

The Eye Candy demo that comes with LiquidFun, adapted for cocos2d-x. Includes two useful classes:

• LFParticleSystemNode: Wraps a LiquidFun b2ParticleSystem into a cocos2d-x node.
• LFPhysicsSpriteNode: Wraps a LiquidFun b2Body into a cocos2d-x node.

Supported platforms:

• iOS

GAF

From GAF homepage:

"GAF stands for Generic Animation Format. GAF is designed to store Flash animations in an open cross platform format for further playback in a multitude of game development frameworks and devices. GAF enables artists and animators to use Flash CS for creating complex animations and seamlessly use them with various game development frameworks."

This sample shows how to use GAF with cocos2d-x. It has 5 different GAF samples and shows how to play sound events with GAF.

Supported platforms:

• iOS
• Android

How To Create New Samples

1、init environment

$ python download-engine.py

$ cd libs/cocos2d-x

$ python setup.py

2、create new sample

$ cd samples

$ cocos new ProjectName -l [cpp or js or lua] 

attension: only create projectName in samples dir, it will be compiled correctly

cocos2d-x-samples's Issues

Link http://cocostudio.download.appget.cn/Cocos2D-X/ is dead

./download-engine.py can't download engine because the link to the engine in lib/config.json is outdated.
According to the links on the official site, it might be
https://digitalocean.cocos2d-x.org/Cocos2D-X/

gl_PointCoord can not be supported on windows and linux for openGL 2.0

@ricardoquesada
Heard from minggo, that you have a solution for this.
Could you please take a look at it?

Rendering one deformable texture on top of one elastic particle group

Hi ricardo, thanks for the great sample!

I've some questions as I need to render textures on top of each particle group to make jelly simulations (e.g. the one in Loco Roco PSP game). I've been googling but can't find much help maybe due to the wrong keyword... Do you have any idea?

I've seen people doing that on Torque2D: https://www.dropbox.com/s/jscm9pks87c4ohl/Squishy.mov

So I think it must be possible on cocos2d as well, just the technique of doing it without shaders...

Thanks!

Compiling LiquidFun-Testbed Xcode 10.2 - Missing files on compile-time

Should these examples work out of the box?

I've been following the steps from https://github.com/cocos2d/cocos2d-x-samples exactly, namely

Download

$ git clone https://github.com/cocos2d/cocos2d-x-samples.git
$ cd cocos2d-x-samples
$ python download-engine.py

Running

Once the samples were downloaded just go any sample, and open the project. eg:

$ cd cocos2d-x-samples/samples/LiquidFun-Testbed/proj.ios_mac
$ open LiquidFun-Testbed.xcodeproj/

However, when I build the LiquidFun-Testbed.xcodeproj, I get

Showing All Errors Only

Build failed    06.01.20, 22:25    698.2 seconds

Clearly, the compiler is looking for files in
/Users/Chris/Desktop/source/repos/3rd party libraries/cocos2d-x-samples/libs/liquidfun/liquidfun/liquidfun/Box2D/Box2D/

but these were never created.

After following the mentioned steps above, Box2D and its code are instead placed in
/Users/Chris/Desktop/source/repos/3rd party libraries/cocos2d-x-samples/libs/cocos2d-x/external/Box2D

...So why is it looking for these files in

/Users/Chris/Desktop/source/repos/3rd party libraries/cocos2d-x-samples/libs/liquidfun/liquidfun/liquidfun/Box2D/Box2D/??

LiquidFun-Testbed/Particle Drawing have not effect when touching movement

I think it related with the override functions about MouseDown 、MouseMove and MouseUp.

Unknown CMake command "pre_build" linux in CMakeList file

Hi! so this occurs when:

On Ubuntu 14.10 64bits, is it just me?

python2 is dead. Kindly update the download-engine.py

Support of python2 ended in 2020. It still exists and can be used to run python2 scripts, but in the end, things can get worse. It's better to adapt it to the python3 version. After all, it's a tiny script, it can't be so hard.

Some link lines weren't drawed in the tests of TestBed,and the original liquidfun also have these effect

How to integrate and run LiquidFun-TestBed in cocos2d-x 3.2

Hello,

I am trying to run LiquidFun-TestBed in eclipse with cocos2d-x 3.2. On importing the project in my workspace, the project gives error in AppActivity.java file that "Cocos2dxActivity cannot be resolved to a type". Can somebody help me with this issue.

LiquidFun-EyeCandy missing Box2D folder?

It seems that LiquidFun-EyeCandy is missing the Box2D folder. Could I just find it from somewhere else and drop it in? Maybe I should get it from the LiquidFun repository?

Swift sample does not with with xcode6 beta4

Due to some changes in Xcode6 beta4, the Swift example does not work out of the box.
A line like
var a = CGFloat(aFixedValue)
results in an error saying CGFloat is not convertible to UInt8. It can be fixed with an extra cast
var a = CGFloat(Uint(aFixedValue))
but I doubt this is the right solution in the long run

xcode 8 build error

"_CTFramesetterCreateWithAttributedString", referenced from:
"_CTFramesetterSuggestFrameSizeWithConstraints", referenced from:
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Blank screen for Liquidfun-testbed problems on XCode 8.3.3

Following the instructions through:

git clone https://github.com/cocos2d/cocos2d-x-samples.git
cd cocos2d-x-samples
python download-engine.py
cd cocos2d-x-samples/samples/LiquidFun-Testbed/proj.ios_mac
open LiquidFun-Testbed.xcodeproj/

Now I attempt to build and it seems the Liquidfun folder is missing -

Showing Recent Issues
No such file or directory: 'cocos2d-x-samples/libs/liquidfun/liquidfun/liquidfun/Box2D/Box2D/Dynamics/Joints/b2PrismaticJoint.cpp'

Checking in the shell reveals the liquidfun folder is empty:

#ls cocos2d-x-samples/libs/liquidfun/liquidfun
.
..

To try and remedy this I downloaded LiquidFun separately, and placed it in the requested folder. This enabled compilation to complete, but when I run the macOS version I am presented with a black/blank window. Interacting with the window (keys / mouse presses) produces logs as expected.
