Can we add font file to our project at runtime?

cocos2d-x C++
#1

I need to download file from server , and use it while app is running. Is that possible? Please show solution

#2

I guess you could download it into where getWriteablePath() stores files for your platform and then at some point before have added that same location to FileUtils search paths.

#3

string path = cocos2d::FileUtils::getInstance()->getWritablePath()+“font.TTF”;

I saved this on above path, now

string path = cocos2d::FileUtils::getInstance()->getWritablePath()+“font.TTF”;
cocos2d::FileUtils::getInstance()->addSearchPath(path,true);

But it crashes, when I try to access this label and says unable to find file font.ttf

Please help

I don’t think you need this. Just specify the path.

cocos2d::FileUtils::getInstance()->addSearchPath(cocos2d::FileUtils::getInstance()->getWritablePath(), true);

I’m not sure if you should use true either without taking a look at the source for this function.

No its not working. get crash log:-
Get data from file(font.TTF) failed!
Can you tell me how should I save file downloaded from server using httpresponse. Here is my way :-

oid SplashScene::downloadFontFromServer(){
    
    HttpRequest* request = new (std::nothrow) HttpRequest();
    request->setUrl("server url");
    request->setRequestType(HttpRequest::Type::POST);
    request->setResponseCallback( [=] (network::HttpClient* client, network::HttpResponse* response) {
        
        if (!response)
        {
            log("onHttpRequestCompleted - No Response");
            return;
        }
        
        log("onHttpRequestCompleted - Response code: %lu", response->getResponseCode());
        
        if (!response->isSucceed())
        {
            log("onHttpRequestCompleted - Response failed");
            log("onHttpRequestCompleted - Error buffer: %s", response->getErrorBuffer());
            return;
        }
        
        
        std::vector<char> *buffer = response->getResponseData();
        CCLOG("buffer size %ld ", buffer->size());
        
        string ret(&(buffer->front()), buffer->size());
        
        CCLOG("%s", ("Response message: " + ret).c_str());
        
        std::string dataFromServer(buffer->begin(),buffer->end());


//save file here
string path  =  cocos2d::FileUtils::getInstance()->getWritablePath()+"font.TTF";

    cocos2d::FileUtils::getInstance()->addSearchPath(cocos2d::FileUtils::getInstance()->getWritablePath(),true);
    
//    CCLOG("pathfor saving file %s",path.c_str());
    
	FILE *fp = fopen(path.c_str(), "w");

	if (! fp)
	{
		CCLOG("can not create file %s", path.c_str());
		return "";
	}
    
    
	fputs(file, fp);
	fclose(fp);

can you tell where I am wrong?

I’d place some breakpoints and see what is happening. your path variable still looks wrong and then you try to open it with FILE?
