![]() Some puzzles involve using the environment to kill an enemy, like turning a valve to spray hot steam at their enemies. The game regularly integrates puzzles, such as navigating a maze of conveyor belts or using nearby boxes to build a small staircase to the next area the player must travel to. Progress through the world is continuous, (except for short loading pauses) with each map of the game connecting directly to the next, with the exception of levels involving teleportation. ![]() Half-Life has no levels it instead divides the game into chapters, whose titles briefly appear on screen as the player progresses through the game. In line with this, the player rarely loses the ability to control the player character, Gordon Freeman, who never speaks and is never actually seen in the game the player sees "through his eyes" for the entire length of the game. Compared to most first-person shooters of the time, which relied on cut-scene intermissions to detail their plotlines, Half-Life 's story is told mostly using scripted sequences (bar one short cutscene), keeping the player in control of the first-person viewpoint. Unlike most of its peers at the time, Half-Life uses scripted sequences, such as a Vortigaunt ramming down a door, to advance major plot points. ![]() Half-Life is a first-person shooter (FPS) that requires the player to perform combat tasks and puzzle solving to advance through the game. It was followed by Half-Life 2 (2004), Half-Life 2: Episode One (2006), Half-Life 2: Episode Two (2007), and Half-Life: Alyx (2020).Īn in-game screenshot of the player battling enemy marines, an attack helicopter, and a gun turret in the level "Surface Tension" Half-Life inspired numerous fan-made mods, some of which became standalone games, such as Counter-Strike, Day of Defeat, and Sven Co-op. In 2020, Crowbar Collective released an unofficial remake, Black Mesa. Valve ported Half-Life to its Source engine as Half-Life: Source in 2004. It was ported to the PlayStation 2 in 2001, along with the multiplayer expansion Decay, and to OS X and Linux in 2013. It was followed by the expansion packs Opposing Force (1999) and Blue Shift (2001), developed by Gearbox Software. By 2008, it had sold more than nine million copies. It is considered one of the most influential FPS games and one of the greatest video games ever made. Half-Life received acclaim for its graphics, gameplay and narrative, and won more than 50 PC " Game of the Year" awards. The science fiction novelist Marc Laidlaw was hired to shape the story and assist with design. ![]() Valve developed it using GoldSrc, a heavily modified version of the Quake engine, licensed from id Software. Valve was disappointed with the lack of innovation in the FPS genre, and aimed to create an immersive world rather than a "shooting gallery." Unlike other games of the time, the player has almost uninterrupted control of the player character, and the story is told mostly in scripted sequences rather than cutscenes. The gameplay consists of combat, exploration, and puzzle-solving. Players assume the role of Gordon Freeman, a scientist who must escape the Black Mesa Research Facility after it is invaded by aliens during an experiment gone wrong. It was Valve's debut product and the first game in the Half-Life series. Half-Life is a 1998 first-person shooter (FPS) game developed by Valve and published by Sierra Studios for Windows.

![]() Dan Morel about photos of an alleged new CVO Road Glide and CVO Street Glide taken from the factory floor. Watch as Jason Fenske of Engineering Explained walks us through VVL and VVT in much more interesting detail. A couple of days ago, we were tipped off by Harley-Davidson blogger Dr. This allows for more control over how much air-fuel mixture is in the cylinder (less under light-load driving, more when power is needed), controlling temperature and emissions.īut that's only a very basic explanation. Essentially, it allows the engine to advance or retard the valve timing using oil pressure. Variable valve timing, on the other hand, is used mainly for emissions control. (VVT) Variable Valve Timing Basically Comes In Two Types: Single (VVT) Continuously varies the timing, of the intake camshaft. Under regular conditions, the engine will use the low-lift cam to operate the valves, but under higher load, a solenoid switches the engine over to the to the high-lift cam (or cams), increasing valve travel and therefore, performance. Instead of having one cam profile for the entire rev range, a VVL engine has two: low-lift and high-lift. Variable valve lift is mainly used to enhance performance. These systems sound pretty similar, but what do they actually do? Luckily, there's a real engineer here to explain it to us. Engine valve systems have mainly been designed to accurately control the. Variable valve lift (VVL) and variable valve timing (VVT) are two of the most popular ones. Valve lift- how much the valves physically open (their opening aperture). But how Source smlive903 Variable valve timing (vvt) systems The lobes on the camshaft are egg-shaped and make contact with the lifter or rocker arm for a specific amount of time (duration). Valve duration- how long the valves stay open. Variable valve timing is a concept that was put in use decades ago in aircraft engines, with experiments in sliding camshafts and other concepts. Manufacturers like to use a lot of acronyms on their cars. Variable valve timing technology controls three key characteristics of the intake and exhaust valves: Valve timing- the points in the piston’s movement at which the valves open and close. ![]() My solution for this is to use google drive on mobile and a standard pdf embed in an iframe on larger screens. I'm using this as a fallback for smaller viewports and simply embedding the above link into my. Just provide a full path to the PDF document and Google will return a HTML formatted interpretation of your PDF (don't forget to set embedded=true). Recently I have started using the Google Drive viewer, which has mostly solved the original problem. That will be a what you see is what you get view of. Just select the document, select Print, and an image of the document should open in your printer dialog (print preview). For me I need to write this one off and look for another solution for our iPad users. You don't need to send the document to PDF in order to see if everything is placed correctly. ![]() I then updated my iPhone to 12.4 and still didnt see the attachments. Anybody else struggling with this one I advise to refer to ' Strategies for the iFrame on the iPad Problem'. Not sure if it broke between 3.23.0 & 3.33.0, but I see a PGP signature attachment (which came across as S/MIME), but a PDF and two ICS attachments arent showing on either iPhone or iPad Pro on iOs 12.3.1. In this instance only the top left portion of the PDF is visible without any horizontal or vertical scrollbars to see the rest of the document.ĭoes anybody know of I workaround for this problem in Mobile Safari?Īfter hours of searching and experimentation I can conclude that this problem is a real mess!! There are a bunch of solutions but each far from perfect. This works fine in all the major desktop browsers with the width of the PDF scaling to fit inside the confines of the iFrame and a vertical scroll bar to view all the pages within the document.Īt the moment however I can't get the PDF to display correctly in Mobile Safari. Go to Safari > Preferences or use the keyboard shortcut of Command + Comma. For recent problems, pick the last hour or day. ![]() The other reason could be its caused by a file that was moved, renamed, or deleted. Option 1 Empty Safari’s Cache And Clear History. Within our web application we are displaying a PDF document in an iframe using the following line of code: To do this, go to Settings -> Apps -> WhatsApp -> Storage and tap on Clear Cache and Clear Data buttons. 9600 is the standard rate, but other speeds are typical amongst certain devices. ASCII charts are very helpful when working with serial terminals.īaud Rate - In short, baud rate is how fast your data is being transmitted and received. ![]() It highly recommended that you read that page as well to get the full picture.ĪSCII - Short for the American Standard Code for Information Interchange's character encoding scheme, ASCII encodes special characters from our keyboards and converts them to 7-bit binary integers that can be recognized by a number of programs and devices. Many of these terms are covered in a lot more detail in our Serial Communication tutorial. Here are some terms you should be familiar with when working within a serial terminal window. For now, just know how to distinguish between the two. We will go over how to create a serial terminal connection within a command line interface later in this tutorial. ![]() Regardless, you can perform some of the same tasks in a command prompt that you could also perform within a terminal window, but it doesn't work the other way around you cannot issue command line statements within a terminal window. Hence the confusion when using that word. In Mac OS, the command prompt is even called Terminal. Terminal vs Command LineĪ terminal is not a command prompt, though the two are somewhat similar. However, this tutorial will not cover these features. Many have network communication capabilities such as telnet and SSH. It is also worth noting that many terminal programs are capable of much more than just serial communication. Just know that means to open whichever one of these terminals programs strikes your fancy. And, often, when reading other tutorials and hookup guides, you will be requested to open a terminal window. When working on a modern operating system, the word terminal window will often be used to describe working within one of these applications. Many terminals use to emulate specific types of computer terminals, but today, most terminals are more generic in their interface. For the purposes of this tutorial, just the word terminal will be used. They are known as emulators, applications, programs, terms, TTYs, and so on. Today, terminal programs are "emulating" the experience that was working on one of these terminals. Connector Basics particularly the USB section.If you need a refresher, feel free to pop on over to these links. You should be familiar with these topics before diving into this tutorial. In this tutorial we will discuss what a terminal is, which terminal programs are best suited for certain situations and operating systems, and how to configure and use each program. There are lots of different terminal programs out there, and they all have their pros and cons. Once you have learned the ins and outs of a terminal application, it can be a very powerful tool in your electronics and programming arsenal. ![]() They allow you to see data sent to and from your microcontroller, and that data can be used for a number of reasons including troubleshooting/debugging, communication testing, calibrating sensors, configuring modules, and data monitoring. In short, serial terminal programs make working with microcontrollers that much simpler. This tutorial is here to help you understand what these terms mean and how they form the larger picture that is serial communication over a terminal. For someone who isn't familiar with these terms and the context in which they are used, they can be confusing at times. These are all words that get thrown around a lot when working with electronics, especially microcontrollers. |
