C++ (Cpp) MeasureChar示例

示例#1

文件： Render.cpp 项目： quantumrain/LD24

void DrawString(Vector2 pos, int flags, Colour colour, const char* txt, ...)
{
	char buf[512];

	va_list ap;

	va_start(ap, txt);
	_vsnprintf_s(buf, sizeof(buf), _TRUNCATE, txt, ap);
	va_end(ap);

	if (flags == kTextCentre)
		pos.x -= MeasureString(txt) * 0.5f;
	else if (flags == kTextRight)
		pos.x -= MeasureString(txt);

	const char* letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.:/-!@";

	for(const char* p = buf; *p != '\0'; p++)
	{
		int c = toupper(*p);
		int sprite = -1;

		if (const char* ofs = strchr(letters, c))
			sprite = 256 + (int)(intptr_t)(ofs - letters);

		if (sprite >= 0)
			DrawChar(pos, Vector2(1.0f), sprite, 0, colour); 

		pos.x += MeasureChar(c);
