We believe that most gamers have come across the game of Apex Legends by now. If not, let us introduce you to this online hero shooting game. The game - free to play, was only accessible for PlayStationon4, Nintendo Switch, Xbox One earlier. However, recently the makers of the game decided to release the game for Android and iOS users. Once it was launched in 2019 as a surprise, it quickly garnered positive reviews and a wide fan base. 

Now you may be wondering as to how one can code a game like Apex Legends. Gamers will be quite excited to know this little knowledge spurt. So here we come with an article which reveals to you - How to code a game like Apex Legends ? No secrets with you ! 

What is Apex?

Apex is a proprietary language that was developed by Salesforce.com.This is an object-oriented language, which allows you to execute flow and transaction control statements. Moreover, the syntax of Apex will look the same as Java, so it will be easy to use. Additionally, it enables developers to add business logic to events. This is included in all types of editions (performance, enterprise, developer, and unlimited edition).

Features of Apex 

  1. Integrated-type:  Apex provides you the built-in support for DML operations like Insert, Update, Delete. To return the set of objects, it has support for inline SOQL and SOSL query.
  2. Easy to use: As the syntax of Apex is similar to Java, it is very easy to use.
  3. Strong integration with data: The multiple queries and DML statements can be easily executed at the same time and the multiple transaction statements are issued on the database.
  4. Strongly typed: Apex uses a direct reference like sObject and if any invalid reference like wrongly typed data is detected quickly.
  5. Multitenant environment: The Apex is designed to protect against the runway code and also from monopolizing shared resources. If any code violates the rules, it gets easily detected with error messages and stops it from running further.
  6. Easy testing: It provides built-in support for execution, easy testing by indicating how much code was covered and which part of the code should perform efficiently.

Workflow of Apex

The workflow of Apex is Somewhat similar to another programming language, that is 

Variable declaration: As this is a Strongly typed language, you need to declare every variable with the correct data type. Declaration 1stAcc is to be declared with data type as a list of accounts.

  • SOQL query:To fetch the data from the Salesforce database, a SOQL query is used.
  • Loop statement:This process is similar to C, C++, and Java. That is, The iteration occurs several times until the statement fails.
  • Flow control statement:The flow control statement has the power to stop, execute, and continue the program according to the statement. For Example: If statement.
  • DML Statement: It performs the records in a database. That is Insertion, upsert, delete operation on the records.

Here are your steps to develop Apex Code:

The Sandbox and Developer edition of salesforce enables you to develop code. So, You can choose either sandbox or developer edition.

Apex code development tools are statement.Force.com Developer Console,Force.com IDE,

  2. After Selecting the developer Console option, you can see a new window.
  3. In that Developer Console Window, You can perform operations like writing and Compiling code, Debugging, Testing, checking performance, SOQL queries, Color coding, and auto Complete.

Writing and Compiling code: you can easily write Code by using the source code editor. And the Compilation errors are automatically detected.

  • Debugging: It automatically identifies the compilation errors.
  • Testing: you can test by viewing debug logs and setting checkpoints.
  • SOQL queries: To check out the performance and to identify issues or errors you can inspect debug logs
  • Color coding: The developer editor uses a color scheme that makes the code more readable and easier.

Execution of Code in Developer Console

  5. Then type the 'USER' for filtering the output as shown above.

So, these are the steps you should follow to execute your code.

So confused, is this talking about Apex Legends the game? Or Apex the javascript framework (they're not related)
