C++ (Cpp) Clock::getAccumTime示例

示例#1

TEST( Clock, tick )
{
	Clock c;

	EXPECT_EQ( 0, c.getDeltaTime() );
	EXPECT_EQ( 0, c.getAccumTime() );

	std::this_thread::sleep_for( std::chrono::milliseconds( 16 ) );
	c.tick();

	EXPECT_LE( 0.016, c.getDeltaTime() );
	EXPECT_LE( 0.016, c.getAccumTime() );

	std::this_thread::sleep_for( std::chrono::milliseconds( 16 ) );
	c.tick();

	EXPECT_LE( 0.016, c.getDeltaTime() );
	EXPECT_LE( 0.032, c.getAccumTime() );

	std::this_thread::sleep_for( std::chrono::milliseconds( 16 ) );
	c.tick();

	EXPECT_LE( 0.016, c.getDeltaTime() );
	EXPECT_LE( 0.048, c.getAccumTime() );
}
