Here are some of the benefits of this Engine: - All free - Large user community spread around the world - Provide full C++ source code - Friendly to everyone from students to professional programmers - Provide a set of editing tools from image to sound - Etc In the topic, the author will focus on learning about this Engine and guide readers to use it to write a complete game II RESEARCH CONTENT 2.1 Research objective - Learning about the Unreal Engine documentation - Applying to program a complete game 2.2 Research Methods Theoretical research methods: - Read and watch tutorials through Blogs, and tutorial websites - Learn through projects and develop further Experimental method: www.irjmets.com @International Research Journal of Modernization in Engineering, Technology and Science [936] e-ISSN: 2582-5208 International Research Journal of Modernization in Engineering Technology and Science ( Peer-Reviewed, Open Access, Fully Refereed International Journal ) Volume:04/Issue:05/May-2022 Impact Factor- 6.752 www.irjmets.com - Presenting game ideas - Plan and sketch ideas - Programming the game according to the proposed idea III LEARNING ABOUT UNREAL ENGINE Structure of a complete project: Figure 1: Structure of a complete project An Unreal Engine project includes the following components: - Toolbar: The main toolbar with basic operations - Modes: includes the simple models provided when you initialize the project - Content browser: is a content manager, allowing users to edit existing content or adding new content to the project - Viewport: Provides the most visual view of the scenes created in the game - Details: provides detailed properties about an object in the game - World outliner: displays all the actors in the game, you can select Info to see details - Sourcecode C++: provides the full C++ source code displayed by Visual Studio 2017 IV INSTRUCTIONS FOR PROGRAMMING GAMES WITH UNREAL ENGINE 4.1 Steps to make games with Unreal Engine - Pre-production stage: This is the planning stage of the game The purpose of this stage is to create a detailed plan with a timeline for each specific stage and finished product requirements for each part of the proposed project - Development stage: At this stage, about 90% of the completion of a game will take place This is the stage where most of the personnel are required to participate in the project - Testing and release: This is the final stage of every game project At this stage, the developer will release test versions for the purpose of detecting errors to conduct optimization 4.2 Manipulating game resources Assets can be understood as game resources Assets can include character models, sounds, materials, etc [4] Unreal Engine provides users with Content Browser to manage in-game assets [5] www.irjmets.com @International Research Journal of Modernization in Engineering, Technology and Science [937] e-ISSN: 2582-5208 International Research Journal of Modernization in Engineering Technology and Science ( Peer-Reviewed, Open Access, Fully Refereed International Journal ) Volume:04/Issue:05/May-2022 Impact Factor- 6.752 www.irjmets.com Figure 2: Content Browser 4.3 Game level design When playing video games, every object that you see, hear or interact with is called a Level [6] In Unreal Engine 4, a Level is made up of a collection of Actors, sounds, lights, and many other elements that work together to create the desired experience for the player Levels in Unreal Engine can have a large size equivalent to reality or a small size with a limited number depending on the programmer's creativity Figure 3: Level Editor main interface Figure 4: Complete level www.irjmets.com @International Research Journal of Modernization in Engineering, Technology and Science [938] e-ISSN: 2582-5208 International Research Journal of Modernization in Engineering Technology and Science ( Peer-Reviewed, Open Access, Fully Refereed International Journal ) Volume:04/Issue:05/May-2022 Impact Factor- 6.752 www.irjmets.com 4.4 Using C++ to build games In this part, the author uses C++ language to create and control the viewing angle of the camera on a game level, including: - Attach the camera to a Pawn - Set key operations - Interact with key operations 4.5 Getting acquainted and programming with Blueprint Visual Scripting - Create enemies with Blueprint [7], [8] Figure 5: Tab Viewport - Interactions between Blueprints: Figure 6: Creating a new Blueprint Interface Figure 7: Handling events when a collision occurs www.irjmets.com @International Research Journal of Modernization in Engineering, Technology and Science [939] e-ISSN: 2582-5208 International Research Journal of Modernization in Engineering Technology and Science ( Peer-Reviewed, Open Access, Fully Refereed International Journal ) Volume:04/Issue:05/May-2022 Impact Factor- 6.752 www.irjmets.com V CONCLUSIONS AND DEVELOPMENT ORIENTATIONS 5.1 Conclusions Some results have been achieved: - Learned and researched about making games with Unreal Engine from sources such as: Blog, Youtube, etc - Applying materials to make games with Unreal Engine In which, the product uses the knowledge: + Apply C++ to game programming + Build a complete character + Build AI on a simple level + Build a complete game level + Learn and program with Blueprint -
