After update cretor version from 2.3.1 to 2.4.0 web-mobile build could not find any project resources. Project works from editor preview.
loadScene: Can not load the scene 'db://assets/scenes/StartupScene.fire' because it was not in the build settings before playing.

in creator v1.9.3 i can pass an array to shader uniform without problems.
I do it like that:
in shader code
uniform vec4 test[2]
in js code
this._program.setUniformLocationWith4fv(“test”,[1.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0])
or if i want to set individual elements of the array i should do that
this._program.setUniformLocationWith4f(“test[0]”, 1.0, 0.0, 0.0, 0.0)
this._program.setUniformLocationWith4f(“test[1]”, 0.0, 1.0, 0.0, 0.0)
this._program.setUniformLocationWith4f(“test[2]”, 0.0, 0.0, 1.0, 0.0)
It works correctly.
I don’t see ways to do it in v2.4. Where did i mistake and what should i do?

This tutorial is inspired by this GitHub repo.
Let’s take the above GitHub repository as inspiration and re-create this idea using Cocos Creator using TypeScript. The full project can be found in this GitHub repo.
Demonstration of non-recursive random map generation process:
Demonstration of the pathfinding process of non-recursive random map generation:
What does the labyrinth look like? The definition of the maze is as follows:
Tthe entrance is in the first column of the second row, and the exit is in the second last row:
The algorithm used to generate and find the maze:
The data structure involved is nn the Script/algorithm folder:
The demo of the code contains two parts:
There are a total of 10 demos, which can be selected through the visualType attribute in the editor:

I made PhysicsSprite3Ds by using Physics3DRigidBodyDes like below.
Physics3DRigidBodyDes rbDes;
rbDes.mass = 0.0f;
rbDes.shape = Physics3DShape::createBox(Vec3(10.0f,10.0f,10.0f));
auto ps3d = PhysicsSprite3D::create("box.c3b", &rbDes);
ps3d->setTag(TAG_MAIN_CHARA);
Also I set collision callback to its rigidBody like below.
auto rigidBody = static_cast<Physics3DRigidBody*>(ps3d->getPhysicsObj());
rigidBody->setCollisionCallback([=](const Physics3DCollisionInfo &ci){
if (!ci.collisionPointList.empty()){
auto rigidBodyA = static_cast<Physics3DRigidBody*>(ci.objA);
auto rigidBodyB = static_cast<Physics3DRigidBody*>(ci.objB);
}
}
When collision is detected, I want to know what objects are collide.
So I want to get PhysicsSprite3D, because I set a Tag to know what it is.
But, I can get only rigidBody.
Are there any ways to get PhysicsSprite3D from its rigidBody.
Thank you.

Hello,
i would get the Url of the normalSprite from a Button, i use:
console.log(this.node.normalSprite.nativeUrl);
console.log(this.node.getComponent(cc.Button).normalSprite.nativeUrl);
but both of them give me : undefined
Where do i wrong?
Thank you

Hello,
i’m facing this issue in iOS specifically, it works fine in android.
here’s the code the I use to unzip zip files :
cocos2d::ZipFile zFile = cocos2d::ZipFile(zipLocation);
std::string fileName = zFile.getFirstFilename();
std::string file = fileName;
ssize_t filesize;
unsigned char* data = zFile.getFileData(fileName, &filesize);
std::string directoryName = cocos2d::FileUtils::getInstance()->getWritablePath();
if (!cocos2d::FileUtils::getInstance()->isDirectoryExist(directoryName))
{
cocos2d::FileUtils::getInstance()->createDirectory(directoryName);
}
while (data != nullptr)
{
std::string fullFileName = directoryName + file;
//log("filename DIR : %s\n", fullFileName.c_str());
if (fullFileName[fullFileName.size() - 1] == '/') {
cocos2d::FileUtils::getInstance()->createDirectory(fullFileName);
free(data);
fileName = zFile.getNextFilename();
file = fileName;
data = zFile.getFileData(fileName, &filesize);
continue;
}
FILE *fp = fopen(fullFileName.c_str(), "wb");
if (fp)
{
fwrite(data, 1, filesize, fp);
fclose(fp);
}
free(data);
fileName = zFile.getNextFilename();
file = fileName;
data = zFile.getFileData(fileName, &filesize);
}
the problem comes from the fact the my zip has nested folders inside, the next code piece is responsible for that :
if (!cocos2d::FileUtils::getInstance()->isDirectoryExist(directoryName)){
cocos2d::FileUtils::getInstance()->createDirectory(directoryName);
}
but it’s unable to create directories, i’m getting : Fail to create directory
the code for createDirectory function :
bool FileUtilsApple::createDirectory(const std::string& path)
{
CCASSERT(!path.empty(), "Invalid path");
if (isDirectoryExist(path))
return true;
NSError* error;
bool result = [s_fileManager createDirectoryAtPath:[NSString stringWithUTF8String:path.c_str()] withIntermediateDirectories:YES attributes:nil error:&error];
if(!result && error != nil)
{
CCLOGERROR("Fail to create directory \"%s\": %s", path.c_str(), [error.localizedDescription UTF8String]);
}
return result;
}
I’m using an iphone 8 emulator.

There are many posts on how to do pixel perfect collision detection of sprites in 2.x and 3.x.
Since 4.x uses metal instead of OpenGL, how will this change? Also since android doesn’t use metal, will we have to have to have a separate implementation for iOS and android?

If you plan to release your game under win32, be careful with the 3rd-party libs, as they are compiled using c++ runtime dependencies of different versions of Visual Studio, such as msvcr110.dll, msvcr120.dll and one of dll’s even with msvcr120D.dll. For those who do not want to have problems with the distribution of their games in Win32, I have prepared a set of such libraries without any dependencies at all (actually i’m even prepared a static versions of those libs for myself, to be able to create standalone exe without any dll’s, but static linking probably could broke some foss licenses, so i’m not include static libs in this package), so you can compile your game in any version of Visual Studio you like, and distribute your game with only one version of mscvredist.exe:

When i debug this on chrome devTool i found that following json file was not loading,
build->jsb-links->assets -> internal ->config.97cbc.json
build->jsb-links->assets -> main -> config.ee485.json
build->jsb-links->assets -> resources ->config.9a721.json
I have deleted assets folder and made build for android again, But got same result. After more debugging i found cc.assetManager.loadBundle in main.js was unable to load these json because fs.getStringFromFile(assets/internal /config.97cbc. json) returns empty string and readJson method fail to parse.
Please let me know if there is an issue in new cc.assetManager, Looking for solution
Please check snaps attached

If you wanted to see what the community in Cocos is building, then you’ll have to see this video. If you want to be in the next one, just add your game to our Game/Demo Showcase section and we’ll try to squeeze you in. Already have some amazing games to share for the next video as well.

There is something wrong with the Label class of cocos2d-x v4 when using a TTF font and trying to print any string with the Euro or Pound symbol (example: 1,00€)
Nothing is printed. If I use the label with a system font it works. And it has nothing to do with the TTf used as the symbol is there and I tried with many fonts.
I haven’t got enough time to properly debug CCLabel.cpp but it looks the private UTF32 string is empty whenever the euro or pound symbol are present of the initial string.
Is this a known issue?
