Comment pouvez-vous déboguer du code sans affecter les performances du jeu ?

Using traces with tags allows to enable/disable traces in certain areas of focus. Traces allows to observe the game with some penalties to performance but not as intrusively as adding a breakpoint. Another option is to use release builds, but turn off optimizations for specific functions or compile units so the rest of the game still runs at acceptable performance. Another thing to mention, we should first write legible/maintainable code, then make sure it works fine, and after that, optimize.

First define the issue you are trying to debug. Then choose most easily accessible debugging tool for your environment. For example , if you are working on windows , then you can use visual studio for debugging your application. Or if you are on MacOs then Mac OS profiling instruments are your best friend.

Ugh, bugs in your game? It's a developer's worst nightmare – a ticking time bomb threatening performance. But fret not! Here's the key: surgical debugging. Imagine a master detective – meticulous, leaving no trace. First, leverage your engine's built-in debugger. It isolates issues without impacting gameplay, keeping things smooth. Second, logging and print statements are your secret weapon. Scatter them strategically, then follow the trail to the bug's lair. Once exposed, eliminate the evidence! Finally, create a controlled environment to reproduce the bug. Think of it as a bug gym – a safe space to test fixes before unleashing them on the live game.

using a debugger can also introduce some overhead and affect the timing and behavior of your game. To minimize the impact of a debugger, you should use it sparingly, disable it when not needed, and avoid debugging in release mode or on a device.

Debugging code without messing up game performance is like fixing a car while it's still running smoothly. Imagine carefully placing little signposts (logging statements) along the road to track what's happening without causing traffic jams. You might also use special tools (profiling tools) to peek under the hood and see which parts need attention without slowing the whole ride down. Think of conditional breakpoints as traffic cops that only stop the car when absolutely necessary. And with remote debugging tools, it's like having a magical mechanic who can work on the engine from a distance, making fixes without causing the car to sputter. These tricks help developers keep the game running smoothly while hunting down and fixing issues.

Modern debuggers allow you to step through code line by line, inspect variables, and set breakpoints to pause execution at specific points. This controlled environment helps pinpoint issues without affecting overall performance.

Optimizing your debugging process is crucial for game development, especially when it comes to performance. Here's a quick guide to debugging code effectively without slowing down your game: Choose a Game-Focused Debugger: Opt for a debugger designed specifically for game code to ensure efficient tracking and performance analysis. Limit Breakpoints: Minimize the number of breakpoints and place them strategically in critical areas to avoid unnecessary slowdowns. Use Conditional Breakpoints: Employ conditional breakpoints to pause code execution only when specific conditions are met, reducing interruptions. By following these tips, you can streamline debugging without compromising the gaming experience

Firstly, learn how the code runs or logic flows. Identify where you need to check. The most important thing is understanding when to check. Breaking runtime before it happens, when it happens or after it happens is the most critical decision. You can either mistakenly give your hardware some time to recover or push your hardware extreme to stop responding. Try to use a native debugger for your own development environment. If it does not give you what you need then look for 3rd-party solution. Secondly, understand what you debugging. Is it UI/UX, game-logic/AI, data or service. Each of these requires different point-breaking. Always consider race-conditions and avoid interrupting it.

Use Profiling Tools: Profiling tools like Intel VTune, NVIDIA Nsight, or built-in profilers in game engines can help you identify performance bottlenecks without altering the game's execution significantly. Introduce debug flags or conditional compilation directives in your code to enable/disable debugging selectively. This allows you to add extra logging, assertions, or performance measurement code only in debug builds. Remote Debugging: Utilize remote debugging techniques to debug the game running on target hardware or devices while keeping the development environment separate. Gather runtime data without significant performance overhead: counters, timers, or logging statements strategically to track specific operations or events.

You can add logs inside the code to check for problems. F.E., the player is moving too slow when pressing the forward Arrow, but you are not sure why > Add Logs to check how the Player horizontal velocity changes when button is pressed.

Although you can write your logs or traces directly to the target machine, there are many limitations such as security concerns, performance, or memory issues. Therefore, it is much more efficient to use tools like OpenTelemetry to collect telemetry data. 1. First, integrate the OpenTelemetry client library into your project. 2. Instrument your application code to generate traces and/or logs. 3. Configure OpenTelemetry exporters to send collected traces and logs to the desired backend. 4. Integrate log analyzing tools with the OpenTelemetry backend. Optionally you can use Firebase Crashlytics to analyze crashes in your app as well.

Balancing debugging and game performance is crucial. Here's a quick guide: Strategic Logging: log selectively in critical code sections to capture key info without overwhelming logs. Dynamic Logging Levels: use different levels to control info flow, minimizing performance impact. Performance Tracing: trace key functions selectively to optimize bottlenecks without disruption. Conditional Tracing: trace specific code paths or events judiciously when needed. By integrating these strategies, streamline debugging while maintaining optimal game performance.

Instead of relying solely on breakpoints and real-time inspection, use logging to record game states, variable values, and the flow of execution. Logging can be enabled or disabled with a toggle to ensure that it does not affect performance during normal gameplay. You can also adjust the verbosity of the logs based on the level of detail you need.

I suggest using levels of logging. Following basic levels (like Info, Warning, Error etc.) can help. For the development lifecycle of the game, I would use: - In development env: Info, Warn, Error - In testing env: Warn, Error - In production env: Error With this simple logic, developer can reduce flow of sensitive information and less consumes resources. Also the development team can benefit from 3rd-Party solutions if the team wants to outsource. For example: - Firebase Crashlytics - BugSnag - InstaBug

Use in-memory logging, then periodic writes to persist log messages, and all on a seperate thread to prevent overhead. Otherwise if you use the same threads etc you will affect timing related bugs/race conditions etc. meaning they will be more difficult to reproduce etc. If the thread dies you may lose the last cached log messages, so if its a crash you are chasing, then turn on stack trace and CPU exceptions etc. (partial debug config), if you have comms (anything will do - http, i2c, spi etc.)you can post telemetry - but if the app/program doesnt have this ability already or you dont have a physical connection for embededd comms, stick with the logs).

I think logging is Good aproach. It helps yhe developer to analyze the process of development in the sequence it happens, it points to potential mistakes in calculations or in the Sequence and it can answer some a lot question on run time

Employ logging and tracing methods in conjunction with your development process. These techniques serve to record and monitor the activity and events within your codebase. By outputting messages, values, or errors to various destinations such as a console, file, or network, logging and tracing facilitate the tracking of code flow and state, aiding in the identification of anomalies or inconsistencies. Nonetheless, it's imperative to recognize that logging and tracing can impose resource overhead and impact game performance. To mitigate these effects, adopt a selective approach, restricting the amount and frequency of logged data while implementing different verbosity levels to suit varying debugging needs.

Utilizing logging and tracing techniques is crucial for monitoring code activity and events. By outputting messages, values, or errors to a console, file, or network, developers can track code flow and identify anomalies. However, these techniques can impact game performance, so it's essential to use them selectively, limit data amount and frequency, and employ different verbosity levels. This allows developers to strike a balance between obtaining valuable insights into code behavior and minimizing resource consumption. Logging and tracing serve as powerful tools for debugging, performance optimization, and gaining a deeper understanding of code execution.

Optimizing code requires effective tools like profiling and benchmarking. Utilize Profiling to identify performance bottlenecks, allowing targeted improvements. Complement this with Benchmarking, comparing different implementations to choose the most efficient one. These tools help fine-tune your code for optimal performance.

Debugging code without affecting game performance is crucial for maintaining a smooth development workflow. Schedule profiling and debugging sessions during downtime or less critical periods. This ensures that debugging activities have minimal impact on the overall gaming experience. Remember that the goal is to balance the need for profiling and debugging with the requirement to maintain optimal game performance. By utilizing this strategies, developers can identify and address issues efficiently without compromising the gameplay experience.

Embrace the power of profiling and benchmarking to delve deep into the performance metrics and resource utilization of your codebase. These techniques offer invaluable insights into the bottlenecks, hotspots, and potential memory leaks within your application, empowering you to fine-tune and optimize critical areas. By leveraging profiling and benchmarking, you can enhance not only the speed and efficiency but also the overall stability of your game. Yet, it's crucial to acknowledge that these techniques can introduce subtle alterations to your code's behavior and outcomes. To circumvent such interference, employ profiling and benchmarking in controlled environments, meticulously compare diverse scenarios, make several builds.

Profiling and benchmarking are essential techniques for measuring and analyzing code performance and resource usage. These tools aid in identifying bottlenecks, hotspots, and memory leaks, enabling developers to optimize code for improved speed, efficiency, and stability in games. However, it's crucial to use profiling and benchmarking in isolation to prevent interference with code behavior and results. Comparing different scenarios and relying on reliable tools help ensure accurate assessments of the code's performance, allowing developers to make informed optimization decisions without compromising the integrity of the game.

Recently, unit testing and test-driven development are two popular terms in game development. Basically what they mean is test and defend your code/logic for the further development. It does not mean the code/logic should be unchangeable. It makes sure for the further development to meet some expected reliability. To achieve that reliability, both in your code and game, the teams can utilize some native or 3rd-Party testing solutions. Every tool requires different approaches. Choose wisely, what you need to test? Gameplay? Code logic? Which is more crucial for your development. Personally, I won't make my project fully test-driven. (Ex. Should I write any unit test for my "Ball Spawner" that exists on my screen? I won't.)

Achieving robust code involves harnessing the power of testing and debugging tools. Employ comprehensive **Testing Tools** to ensure code correctness, identifying and fixing issues early in the development process. Simultaneously, leverage Debugging Tools to trace and eliminate bugs efficiently. By integrating these tools seamlessly, you enhance code reliability and expedite the development cycle.

Many game engines and development environments offer built-in debugging tools that can help you identify and fix issues without a major performance hit. These tools can range from visual scripting debuggers to memory leak detectors.

Unlock the potential of testing and debugging tools as indispensable aids in your software development journey. These versatile applications or libraries offer a spectrum of functionalities, ranging from automating and streamlining debugging processes to facilitating the creation and execution of test cases. By harnessing testing and debugging tools, you can efficiently troubleshoot, simulate various environments, and visualize complex data structures or algorithms, ultimately saving valuable time and effort while minimizing errors. Nevertheless, it's paramount to recognize that reliance on such tools may introduce dependencies and limitations within your codebase. When I made Cubegame 9x, I heavily debugged with an in-game menu.

It is recommended to have no Debug statements in the production build to avoid degradation of performance. A good way to ensure this is to use existing libraries that take care of hiding log statements during production build. In Unity, I usually write a static class with helper functions to handle logging. This allows me to write platform-specific logs and keep track of all the log statements I've written

Basic coding practices will cover the initial development process. Most of the time, production will push the team to develop a game in short period of time. Especially in mobile game development, this is a common production practice. Setting a code style or deciding on a naming convention will help the team on their journey. These tiny details can help a developer to work on the same project without the help of the author of the project. While working on bigger projects, the developers should look for opportunities for refactoring time to time. Preventing god classes or code duplications can make the project more maintainable and easy to work on. Lastly, if it works, it works. Don't push the code for perfection. Just keep it readable.

It is always good to use good code practises. Following them can give provide guaranties that the code easy maintainable, exstensible and easy understandable

In the development of Cube Game 9x, we prioritized optimization for both Windows 95 PCs and modern Windows 11 systems. This involved extensive testing of diverse code variations. Integral to this process were good coding practices, which serve as fundamental habits ensuring clarity, readability, and maintainability in code. By adhering to these practices, we aimed to preempt common errors and bugs, easing future debugging and modifications. Our approach encompassed utilizing meaningful names, maintaining consistent conventions, and comprehensive documentation. Structuring the code systematically facilitated navigation and comprehension; to insure your game goes as smoothly as mine, be extra verbose and clear always.

Debugging in games using feedback involves gathering information from players about bugs, glitches, or other issues they encounter while playing the game, and then using that feedback to identify and fix those problems. This can be done through: Bug Reporting Tools: Implementing in-game bug reporting tools that allow players to easily report issues they encounter, along with details such as when and where the problem occurred. Community Forums: Maintaining active forums or community spaces where players can discuss issues they encounter, providing valuable insight into common problems and potential solutions. Player Surveys: Conducting surveys to gather feedback on specific aspects of the game, including bugs and glitches

Never test and debug is production is the most common mistake most people make. Also optimize as low as possible by going close to bare metal (lower level code means less interpreter operations) as possible when necessary. Another often missed tips is take the time at the start of the project to architect it. That few hours given to the task will save you from snowballing technical debt and man-hours in the long run.

There are many additional risks if you attempt to "debug code without affecting game performance." Generally, the best bug fixes will cause games to run slower. There are other dangers with bug fixing. Repairing collision detection and weapon settings will turn fast shooters into slow dances. Fixing inventory bugs and quest errors makes avatar eyebrows twitch. Fixing resource balance and AI pathfinding makes AI question their existence and core motivation. Patching memory leaks generally makes game color schemes distort. Reworking story and plot holes makes devices overheat. Skip debugging. Embrace the jank.

Debugging and optimising are different things. If you're investigating unexpected behaviour or a crash, it usually doesn't matter if the title is running a bit slower, unless in a rare case when the issue is related to framerate. When the programmer is stepping over lines of code in the debugger, the program is in break mode so performance is not a consideration.

Implement a debug layer or mode in your game that can be toggled on and off. This layer can include performance metrics, debugging information, and controls for manipulating the game state. The debug layer allows you to access detailed information and control elements useful for debugging without embedding heavy debugging code in the game's core functionality.

The developer should remember debugging is a process: - Identify the bug - Understand what causes the bug - Come up with a solution - Fix the bug Understanding the cause and finding a solution is the most critical steps. If the developer don't really understand the cause, the developer will come up with wrong solution. After the fix, the game will show more bugs than the initial state. Not good! Also the developer should think about the scope of the fix. Sometimes a complex bug should be ignored and the developers should look for other bugs to fix. Why? Let the complex bug depends on the core-game logic. Would the developer change some really crucial code in game logic, just to fix a characters eye glitch? I don't think so.

Depends what the environment you're using and want you are debugging for. If you are doing performance testing, the easiest thing to do is see how fast the operation you are working on is completed, or how well the program runs where you're testing it.

This is a massive onion with an equal mass of layers. Often the best place to begin, in my experience, is to know where you are in comparison to the blur of objects, ideas, process, on and on, that are hurtling through the creative and technical space around you that have also been known to not play nice with each other. It may sound ridiculously simple but separate from the fray. Branch.

In my perspective, you should always keep an exact copy of the live version so you can work on bugs without interfering with gameplay. It’s very good practice to let users know you’re aware of the bug and offer compensation in case of monetary loss.
