Instead they get pointed to (referenced) by all the towers the user creates. They don't get instantiated for every single tower instance the user creates. In your case I would just use this Tower base class and subclass it with all the towers at every single level possible that you can instantiate as startup, like BlueTowerLv1, BlueTowerLv2, GreenTowerLv1, etc, with a reference from BlueTowerLv1 to BlueTowerLv2 so that it knows what tower to use when leveling up (a null/nil for next_tower could indicate that the tower has reached a maximum level). You'd want the factory to also handle permanent tower upgrades, as it will be the one to know what upgrades to what and how. It would go something like this (excuse the Java syntax): public static Tower makeGreenTower() Just make a class that knows about the various defaults, and ask it to make whatever flavour of tower you want at the time. You do have a valid point that making a subclass just to set some default values seems ridiculous. And if at some point in the future you want to make towers that give temporary bonuses to some other towers, wouldn't you want for each one to have their own stats fields? Why on Earth would it bother you that a range value is stored in every instance of a tower? Are you trying to save the extra 2 bytes per instance? If you're severely memory constrained in your game, that's a different matter, but that doesn't sound like the problem. How should I group these properties together while still allowing individual turrets to be upgraded separately? Ideally I could be able to design these tower types in something like JSON where I can dynamically load them to the game. So my question is entirely about the design/architecture/structure of the system. Using subclasses like this would also lead into the common values being copied into every instance, so if my subclass GreenTower defaulted range=800 for all my turrets, it would mean that the value 800 would be stored separately into every instance (when they could just use a common value). Literally the only thing they would do is change the default values for the _init_'s arguments. The reason I don't just subclass Tower to create my custom tower types is because they don't really add anything to the class. but they're still individual instances, so it would feel stupid to copy all of these common properties with the same values to every instance separately. So I began with a Tower base class with all the properties I can think of: class Tower(Entity):ĭef _init_(self, image, size, position, attack_speed, attack_damage, attack_splash_radius, attack_range, cost):īut the problem is, all turrets of the same type have same range, same attack speed, same cost, etc. What this means is that I need some kind of generic way to explain how all towers of similar type work, yet I need each instance to be separated. Surface.blit(self.image, self.position, self.size)Īlright so I want my game to work similar to Vector TD, where you have multiple different types of towers that can be build, but you can build multiple instances of each type, and each instance can then be upgraded individually. So, since both minions and towers have a size and a position, as well as a sprite image, I felt like it'd be appropriate to create a common base class: class Entity:ĭef _init_(self, image, size, position): I'm personally using Python and pygame, but I'm looking for generic design answers that can be applied to any OOP language. I'm trying to create a Tower Defense game where minions move through a labyrinth and you can build towers on top of the labyrinths' walls to stop the minions.

It seems to me, a middle millennial, that users who see themselves as part of #alttikok, #deeptiktok, or #elitetiktok share my complaint about the hyperredundancy of noises on TikTok. Like every generation before them, zoomers on TikTok have self-sorted into mainstream and alternative factions. But this raises the question: When you add your own contribution to a pile of same-sounding videos, does it really satisfy the call to create? The sound-swapping functionality that limits the app musically is what makes the barrier to entry lower than it was on any preceding app: The daunting challenge of the blank page is replaced by an endless list of challenges to try your hand at. In those moments, it crosses my mind that maybe TikTok simply isn’t for the consumer, but the creator. But just as frequently it plunges me into an aural brain-mush of mind-numbing sameness so bleak I wish I’d never sought it out in the first place. When I turn to TikTok to break up the monotony of my socially distanced life, it sometimes delivers with creative surprises and unbridled joy. A spin through TikTok is like going through your entire FM radio dial and hearing the same jingle in nine different ads, the same 15-second sections of three different hit songs playing on four stations apiece, and a smattering of varyingly successful adaptations of songs from years past. What is new is the consumer experience: I doubt that any medium has ever bombarded the listener with the same thing over and over like TikTok does. Whether that’s crafting a catchy earworm, covering one with as much skill and aplomb as you’ve got, or parodying it into something funny and new, the methods are probably as old as the recording industry itself. But the goal is, as ever, to create something that resonates with people. Dances might be a little flatter so your entire family can do them in a challenge hooks might be bassier pop hits perhaps a bit more gimmicky. The existence of TikTok hasn’t changed the act of musical creation all that much. But 15 seconds is still a default duration in the interface. Now recording can extend beyond 15 seconds, up to 60, or longer for videos imported from another app. The former is a relic of an old limitation: TikToks could previously only be recorded in 15-second increments, strung together for a maximum duration of 60. When you start creating a video in the app, TikTok suggests two durations: 15 seconds and 60. But the feature that differentiates TikTok from Vine, its chief predecessor in short-form video, is the ability to record a video for the visual component of your TikTok but easily swap out your own recorded sound with sound uploaded by any other user on the app. The visual element and sound can be recorded together and posted as is, like any old video you might take on your smartphone’s camera. A TikTok’s basic elements are video and sound, with an endless supply of effects available to apply to either. The design of TikTok has a lot to do with why you hear the same sounds over and over. The music ranges from vibrant uptempo material (the title track and pulsating “Nutville”) to mellow mid-tempo grooves (“Pretty Eyes”). The pianist fronts a quintet featuring rising Philadelphia trumpet star Woody Shaw, and tenor saxophonist Joe Henderson, who are augmented on three tracks by trombonist J.J. Silver’s family originated in Cape Verde, a Portuguese-speaking island off north-west Africa, and this, his 13th Blue Note album, paid homage to his ancestral roots. One of hard bop’s chief architects, Connecticut-born pianist-composer Horace Silver was also a co-founder member of The Jazz Messengers and helped to establish the two-horn frontline (trumpet and saxophone) as the norm in small-group jazz. The musical alchemy they summon is spellbinding.Ĭlick to load video 46. Cherry and his cohorts improvise – both as individuals and collectively – on several different musical themes that flow into one another in a free and organic way. Featuring Argentine saxophonist Gato Barbieri, bassist Henry Grimes, and drummer Ed Blackwell, the album consists of two extended suites. Having appeared in the late 50s and early 60s on significant envelope-pushing LPs by jazz iconoclasts Ornette Coltrane, John Coltrane, and Albert Ayler, Cherry presented his unique personal musical manifesto on Complete Communion, his debut as a leader. Oklahoma-born trumpeter Cherry was 29 when he recorded this groundbreaking album, the first of three long-players for Blue Note. Let us know in the comments, below, which ones you think we may have missed. This list of 50 albums is a mere fraction of the LPs that Blue Note has put over the years. It is a mission that he never wavered from, nor have the Blue Note albums that have followed in his illustrious footsteps. But when Alfred Lion started the label in 1939 with a recording of boogie-woogie pianists Meade Lux Lewis and Albert Ammons, his intention was simple: To release music that he felt was important. Blue Note is unquestionably the most iconic jazz label there’s ever been.
If the brand already has a color scheme or a visual aesthetic, consider picking a background image that adheres to that style. You can also consider how the text in your thumbnail may appear against the background image. Look through your video for a frame that's representative of the video without giving away too much information. The background image takes up the majority of the space in your thumbnail, and most creators use a moment from their video to give viewers an idea of what the video looks like.

It’s suggested to use a private readonly static object to lock. A reference to a waiting-queue, which contains the threads that are waiting for notification of a change in the state of the lock-object.A reference to a ready-queue, which contains the threads that are ready to obtain the lock. A reference to the thread that currently holds the lock (through the specific lock-object).So, one specific lock needs to use a specific object, and if two separate locks are needed, two separate objects need to be used Monitor.Enter() acquires an exclusive lock based on the lock-object, and Monitor.Exit() releases the lock. The Monitor based locks are uniquely identified with an object. NET specific class used for exclusive locks. Use the other synchronization constructs for specific needs, for example, when you want to allow a specific number (more than one) of threads to access a critical section of code. It’s almost always advised to use lock() over other synchronization constructs, as chances of writing error-prone multi-threaded code is much less. The compiler translates the lock statement into a Monitor.Enter() and Monitor.Exit() pair. NET, the lock() is constructed with Monitor class internally. It can lock a section of code that needs to be handled in thread-safe way. The lock() keyword is the most widely used construct for thread synchronization. Let's now dive into some code in C# and see examples of some the above-mentioned synchronization constructs. ConcurrentDictionary: thread-safe collection of key-value pairs.ConcurrentStack: thread-safe LIFO collection.ConcurrentQueue: thread-safe FIFO collection.ConcurrentBag: thread-safe collection of unordered items.Some of the very useful thread-safe collections are That means, they can be read or be written safely even when multiple threads are accessing them concurrently. The last synchronization technique we have are the thread safe or concurrent collections.NET Framework 4.0 introduced a new bunch of collections under the namespace, that are thread-safe by nature. The volatile keyword, Thread.VolatileRead, Thread.VolatileWrite. There are three types of nonblocking synchronization constructs: By using this particular technique, we are able to protect access to a common field with specific access rules. Monitor.Wait(), Monitor.Pulse(), Monitor.PulseAll()Īnother synchronization technique we have is called nonblocking synchronization.Event wait handles ( ManualResetEvent, AutoResetEvent, CountdownEvent).Thread interaction (or thread signaling) means that a thread can pause and wait until a notification is received from another thread. ReaderWriterLock / ReaderWriterLockSlimĪpart from locks, we also have the notion of Signaling Constructs for synchronization.There are also two different types of nonexclusive locks available: Nonexclusive locks, on the other hand, allow a limited number of threads to access a single resource or piece of code at the same time. lock(), Monitor.Enter() - Monitor.Exit(): Actually lock is just syntactic sugar of the Monitor.Enter - Monitor.Exit construct in C#.There are two different types of exclusive locks available: Until the thread finishes executing that code, no other thread will be able to enter (e.g. There are two types of locks: exclusive and nonexclusive.Įxclusive locks only allow one thread to access a certain piece of code exclusively. So, only one thread (person) can enter the block of code (room) protected with a lock at any given point in time. The next person needs to wait until the previous person comes out and gives back the key. Locks create something like a room with a lock, for which only one key is there and only the person with the key can enter. Using locks we can lock a section of code that needs to be handled in a thread-safe way, or commonly known as a “critical section” of code. A lock limits the number of threads that can perform any kind of activity on a certain piece of code. In today's Part 4 of this small series on Threading, Tasks, Async Code and Synchronization Techniques we are going to explore details on the various synchronization techniques supported for protecting access on a sensitive block of code between multiple threads and see some examples of the constructs we use in C#.Īs we saw in the previous article, the first and most important technique we have is the use of the lock keyword. |
