Error cs0119 expression denotes a type where a variable value or method group was expected - Исправление ошибок и поиск оптимальных решений проблем

Basically im writing a script and i get this error.

error cs0119 expression denotes a type' where a variable' value' or method group' was expected

Here is my code:

using UnityEngine;
using System.Collections;

public class BallControl : MonoBehaviour {

    void FixedUpdate () {

        float moveHorizontal = Input.GetAxis ("Horizontal");
        float moveVertical = Input.GetAxis ("Vertical");

        Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);

        rigidbody.AddForce (Vector3);
    }
}

Im trying to make a script that will make a sphere (ball) move using WASD or arrow keys. I am following an online tutorial. And i am sure i did evrything correct.

Maybe, you mean to apply movement onto the rigidbody?

//rigidbody.AddForce (Vector3);
rigidbody.AddForce (movement);

А теперь по делу.
transform.rotation = Quaternion (new Vector3 (transform.rotation, transform.rotation, rotation));
Вы СОЗДАЕТЕ объект типа Quaternion , а при создании объектов используется new (выделение памяти и тд и тп).
тоесть должно бы быть
transform.rotation = new Quaternion (new Vector3 (transform.rotation, transform.rotation, rotation));

Если же все таки вы используете не новый созданный объект, а хотите просто метод над кватернионом , то было бы
Quaternion.НужныйМетод(параметры метода). а в вашем случае вы использовать пробуете конструктор объекта (параметры для него) без выделения как такового объета

Многовато повторений и так уже, но повторюсь — вам бы какой нибудь курс «Основы программирования» в обязательном порядке

Я новичок. поэтому не понимаю из-за чего возникает ошибка: error CS0119: Expression denotes a `type’, where a `variable’, `value’ or `method group’ was expected
Я вижу, что у GetComponent(Light) не вызывается свойство enabled, но я не понимаю, почему это происходит. Скрипт взяла с интернета.
Подскажите, пожалуйста, как это исправить.

using UnityEngine;
using System.Collections;
 
public class Trigger : MonoBehaviour {
public GameObject LightG;
    int check=1;
    
    void OnTriggerEnter(Collider other)
    {
        if(check==1)

        else if(check==0)
        if(other.collider.tag=="Player")
        LightG.GetComponent(Light).enabled=true;
    }

Create variable of above event.
Subscribe event using AddListener method.
Invoke event

How to program with unity?

The workflow in Unity goes something like this:

Create an entity to serve a role in the game (blank GameObjects can be used for abstract logical tasks).
Write or find a class file, and add it to the entity as a script (using the Add Component button in the inspector view.
Run > test > debug > repeat until it works and move on to the next element of the game.

Astronomy.

Is Unity C# or C++?

Both Unity and UnrealEngine utilize C++ in their source code: Unity is partially written using C++ and C#, whereas Unreal Engine is written in C++ entirely. C++ is widely used to develop high-tier game engines and critical service applications where optimal resource utilization and performance are a priority.

Is Unity coded in C?

The Unity runtime is written in C/C++. This runtime is used in any build you create using the editor — for webplayers and plugins it is installed separate from your build, whereas it is included in it for stand-alones and other platforms such as iPhone and Wii.

What is Unity C#?

The language that’s used in Unity is called C# (pronounced C-sharp). All the languages that Unity operates with are object-oriented scripting languages. Like any language, scripting languages have syntax, or parts of speech, and the primary parts are called variables, functions, and classes.

Is Unity just C#?

According to its official documentation, C# is the only language that Unity supports natively.

Is C# easier than C++?

Overall, C++ is a more complex language with a steeper learning curve that offers increased performance, whereas C# is easier to learn and more widely used, which makes it great for beginners.

How difficult is C#?

C# is one of the easiest programming languages to learn. C# is a high-level, general-purpose programming language that is easy to read because of its well-defined class hierarchy. It is the perfect language for beginner developers as it will be straightforward to grasp compared to most other languages.

Is C# similar to C++?

While related, C++ and C# are very different languages. Although they share a common ancestor, C++ and C# have become very different languages. As stated earlier, C# is a higher-level language compared to C++ or C.

Is C# different from C++?

Key Differences C++ is known as an intermediate-level language that adds object-oriented features to its base C, whereas C# is a high-level language. C++ compiles programs to Machine Codes, and C# compiles programs to Common Language Runtime or CLR.

Can I use Python in Unity?

Python for Unity requires installing third-party software. Python for Unity provides: A Python Script Editor window principally aimed at Technical Artists who want to run short scripts and easily create new menu items that run Python code.

Can you learn Unity without knowing C#?

No, you will really need C# for Unity. But, C# is very similar to Java, you shouldn’t have any problem learning it.

Can I use Java in Unity?

Using Java plug-ins Unity uses the Java Native Interface (JNI) both when calling code from Java and when interacting with Java or the Java VM(Virtual Machine) from native code or C# scripts.

Should I learn Unreal or Unity?

If you’re a beginner looking to publish your first title, Unity’s user-friendliness and royalty-free pricing structure is an attractive option. However, if you’re looking to feature superior graphics within your game and have access to a wide knowledge base, Unreal is a better fit.

What is a Unity project?

Unity-Generated Code Projects. Once you have code in your project, Unity creates one or more project files in your root folder (which isn’t visible in the Unity interface). These are not the Unity engine binaries, but instead the projects for Visual Studio or MonoDevelop in which you’ll edit and compile your code.

What is Unity engine?

Unity is a native C++-based game engine. You write code in C#, JavaScript (UnityScript) or, less frequently, Boo. Your code, not the Unity engine code, runs on Mono or the Microsoft .NET Framework, which is Just-in-Time (JIT) compiled (except for iOS, which doesn’t allow JIT code and is compiled by Mono to native code using Ahead-of-Time [AOT] compilation).

What is the coordinate system in Unity?

Unity uses the left-hand coordinate system, in which you think of the coordinates of your computer screen as X (horizontal), Y (vertical) and Z (depth, that is, coming in or going out of the screen). In game development, it’s quite common to use vectors, which I’ll cover a bit more in future articles.

What is a package in Unity?

A package is a .unitypackage file that contains prepackaged resources—models, code, scenes, plug-ins—anything in Unity you can package up— and you can reuse or distribute them easily. Don’t check something off here if you don’t know what it is, though; your project size will grow, sometimes considerably.

What is Unity Asset Store?

Perhaps the most powerful part of Unity is the Unity Asset Store, arguably the best asset marketplace in the gaming market. In it you can find all of your game component needs, such as artwork, 3D models, animation files for your 3D models (see Mixamo’s content in the store for more than 10,000 motions), audio effects and full tracks, plug-ins—including those like the MultiPlatform toolkit that can help with multiple platform support—visual scripting systems such as PlayMaker and Behave, advanced shaders, textures, particle effects, and more. The Unity interface is fully scriptable, allowing many third-party plug-ins to integrate right into the Unity GUI. Most, if not all, professional game developers use a number of packages from the asset store, and if you have something decent to offer, you can publish it there as well.

Can you make zombies in Unity?

You can bring a bunch of zombies into a scene and control them, but you wouldn’t create zombies in the Unity default tooling.

Is Unity scriptable?

The Unity interface is fully scriptable, allowing many third-party plug-ins to integrate right into the Unity GUI. Most, if not all, professional game developers use a number of packages from the asset store, and if you have something decent to offer, you can publish it there as well.

Why is Unity so flexible?

As a programmer you have a great deal of flexibility in Unity because you can extend the editor with your own custom windows that behave just like the Inspector, Scene or any other built-in windows in the standard editor. Adding your own tools to Unity supports you and your team’s unique workflows and needs, ultimately boosting efficiency.

What are the properties of components in Unity?

In the above example, some properties of the light are range, color, and intensity.

What is IL2CPP in Unity?

IL2CPP: This is a Unity-developed scripting backend which you can use as an alternative to Mono when building projects for some platforms . When you choose to build a project using IL2CPP, Unity converts IL code from scripts and assemblies into C++ code, before creating a native binary file (.exe, apk, .xap, for example) for your chosen platform.

Why use ECS in Unity?

In addition to being a better way of approaching game programming for design reasons, using ECS puts you in an ideal position to leverage Unity’s C# Job System and Burst Compiler, letting you take full advantage of today’s modern hardware.

What are the three building blocks of Unity?

All gameplay and interactivity developed in Unity is constructed on three fundamental building blocks: GameObjects, Components, and Variables. Any object in a game is a GameObject: characters, lights, special effects, props–everything. Components. GameObjects can’t do anything on their own.

What language does Unity use?

Unity supports C#, an industry-standard language with some similarities to Java or C++

Why is debugging and tweaking important in Unity?

Tweaking and debugging is efficient in Unity because all the gameplay variables are shown right as developers play, so things can be altered on the fly, without writing a single line of code. The game can be paused at anytime or you can step-through code one statement at a time.

What is UnityC dashboard?

See it all in one place: The UnityC dashboard lets you see all your client communications, documents and progress on one screen.

What is UnityC document management?

Capture and review important documents in realtime across all your clients in your dashboard. UnityC’s cloud-based document management system replaces email exchanges, phone calls and searching for attachments.

Is UnityC for everyone?

UnityC is for everyone. Whether you are a lawyer using Unity, a real estate agent, mortgage broker or home buyer – everyone can benefit from UnityC.

Does UnityC have a referral engine?

Grow your business using UnityC’s built-in referral engine. It’s never been easier for stakeholders to refer clients to you. Complete, ready-to-action referral info shows up in your UnityC dashboard and can quickly be made into active matters.

What is Unity assertion?

Unity is most obviously about assertions. Assertions are statements of what we expect to be true about our embedded system. At their most basic, they are things like this:

What is Unity test suite?

Unity is designed to help you make the most of your test suite. It features a rich set of assertions so you can find the perfect match for your needs

What is a test in C?

One or more of these lovely assertions go into each test. A test is just a C function that takes no arguments and returns nothing. By convention, it starts with the word «test» or «spec»:

What is the first argument in Unity?

The first argument is the expected value. The second argument is the value you are testing. It’s printed clearly in a format that is most convenient to you, the test writer. In fact, Unity can handle all sorts of types, not just integers.

Can you use CMock in Unity?

Let’s do this! First, you need to download your tools. Very likely, you’ll start with just Unity. But you may choose to use Ceed ling or CMock too. If you’re not sure, maybe you want to start by using our Decide-O-Tron 3000. If you opted for Ceedling, you can start there to learn more. Otherwise, let’s learn a bit about making a Unit Test with Unity.

Can you use test_assert in C?

You could use nothing but the TEST_ASSERT above, and you could test almost anything that your C code can handle… but when something went wrong, you’d see something like this:

Is Unity a toolchain?

Unity is easily integrated into your toolchain. Start with just the basics, then power up with optional scripts or features later.

Which is easier to code: C# or C++?

If you really know both, C++ is easier to code in than C#. For examples C++ ‘s template system (which C# named generics) is more versatile than generics and the new dynamic keyword combined (you’re allowed to use T however you like, including == and function calls, giving compile-time errors when the actual type can’t do that.) You can add real variables and functions to a C++ interface. C++ doesn’t need C#’s new ref-return function since you can do it directly (int& a1=C. age,) which is a nice time-saver. The «using»‘s are more flexible. You don’t need a special rule for creating a delegate since Typedef works for everything, including function-types.

Can you code in C++?

Just to remind you of lordofduct‘s post above, you CAN code in any language that .NET supports, and that includes C++/CLI, which basically is C++. If all you care about is using «&» instead of «ref» and other clunky C++ syntax, then it will get you what you want. If you want to use a bunch of native DLL’s from other places, it won’t help though.

Is CPP a plugin?

CPP is supported as plugins. This means you use your normal workflow of writing cpp code to build a dll with the functions you want (so far nothing out of the ordinary here) and access it in Unity through calls from your C# scripts. This should be trivial for someone that already knows cpp.

Can you write a plugin for Unity?

You can write external software that can be used as a ‘plugin’ for unity. This is useful if say you have some code in C++ that is fast at doing something (like say OpenCV to calculate objects in a picture). Under right settings, you can compile C++/CLI to a dll usable in mono… so loadable in unity. But you’ll be writing and compiling your code …

Is Unity transparent?

You get Qs about transparent jpegs because browsers have an easy but limited «color X is transparent» rule, which Unity wants no part of. Even before Unity came around, game programmers used C++.

Is Unity 2021.2 available?

Unity 2021.2 is now available as the latest Tech release.

Can you use C# in Unity?

Unity affords you the flexibil ity to use cpp if you want to, you just have to use C# to access it. How much you write in C# is entirely up to you. You could write everything in cpp and just make simple calls from a very basic C# front end in Unity if you wanted to.

What is the editor in C#?

The Editor passes a default set of options to the C# compiler. To pass additional options in your project, see the documentation on Platform Dependent Compilation.

Does Unity support unmanaged functions?

Unity supports unmanaged functions pointers as introduced in C# 9, but it doesn’t support extensible calling conventions. The following example code provides more detailed information about how to correctly use unmanaged function pointers.

How does Unity work?

Unity allows you to choose the lifetime of the objects it creates. By default, Unity creates a new instance of a type each time you resolve that type. However, you can use different lifetime managers to specify a required lifetime for resolved instances. For example, you can specify that Unity should maintain only a single instance (a singleton). It will create a new instance only if there is no existing instance. If there is an existing instance, it will return a reference to this instead. There are also other lifetime managers you can use.

What is Unity configuration?

Unity allows configurations where dependencies are resolved from the container. But it also provides an easy way to configure injection of values at registration. In other words you could provide values for dependencies to be registered and used during subsequent resolutions.

What is a Unity container?

Unity Container is a full featured, general-purpose IoC container for use in any type of .NET application. It is Open Source and released under Apache 2.0 license. Unity is extensible. Anyone can write an extensions that changes the behavior of the container, or adds new capabilities.

What is registration in Unity?

Registrations allow mapping between service types and implementation types. Create a blueprint of how instances instantiated, initialized, and managed. For generic types it creates internal mini factories that used to generate concrete types. Unity supports three ways of registering types:

Can you use Unity to create objects?

You can use the Unity container to generate instances of any object that has a public constructor (in other words, objects that you can create using the new operator). During object instantiation Unity can:

Does Unity override dependency values?

Unity also allows overriding of any dependency values during resolution. It could override any configured or resolved value during resolution of the type.

Can Unity resolve a concrete reference?

Unity can resolve any concrete, constructable reference type without registration. For example calling container.Resolve<object> () will produce an instance immediately. Registrations allow mapping between service types and implementation types. Create a blueprint of how instances instantiated, initialized, and managed.
