» 2025-05-21 20:09:32 Update :-) Pozostało jeszcze napisać poprawkę dla słów dłuższych niż zadana szerokość linii. Tzn żeby słowa też zawijało gdy są dłuższe niż linia :-) std::vector < sf::Text * > wrap_text( int line_width, std::wstring text ) {
std::vector < sf::Text * > wrapped_text;
std::wstring line = L"";
std::wstring word = L"";
for( auto & character: text ) {
if( sf::Text( word + character, font, characterSize ).getGlobalBounds().width > line_width ) {
if( line != L"" ) {
sf::Text * t = new sf::Text( line, font, characterSize );
wrapped_text.push_back( t );
line = L"";
}
std::wstring l = L"";
word = word + character;
for( wchar_t & c: word ) {
if( sf::Text( l + c, font, characterSize ).getGlobalBounds().width > line_width ) {
sf::Text * t = new sf::Text( l, font, characterSize );
wrapped_text.push_back( t );
l = c;
} else
l = l + c;
}
sf::Text * t = new sf::Text( l, font, characterSize );
wrapped_text.push_back( t );
word = L"";
}
else if( sf::Text( line + word + character, font, characterSize ).getGlobalBounds().width > line_width )
{
sf::Text * t = new sf::Text( line, font, characterSize );
wrapped_text.push_back( t );
line = L"";
word = word + character;
}
else if( character == L'\n' ) {
if( sf::Text( line + word, font, characterSize ).getGlobalBounds().width > line_width ) {
sf::Text * t = new sf::Text( line, font, characterSize );
wrapped_text.push_back( t );
sf::Text * t2 = new sf::Text( word + L"\n", font, characterSize );
wrapped_text.push_back( t2 );
line = L"";
word = L"";
}
else {
sf::Text * t = new sf::Text( line + word + L"\n", font, characterSize );
wrapped_text.push_back( t );
line = L"";
word = L"";
}
}
