Glitches and bugs in video games can be frustrating and disrupt gameplay. By addressing these top bugs and glitches during the development phase, game creators can deliver smoother, more enjoyable experiences for players. Here are the top 20 most common video game glitches and bugs with solutions to avoid them:

1. Clipping Issues

Clipping is one of the most common visual bugs in video games, where characters or objects pass through walls, floors, or other solid surfaces. This usually occurs due to faulty collision detection, causing parts of the character or item to move through objects.

Why It’s a Problem:

• • It breaks immersion for players and can sometimes allow them to bypass key obstacles or game mechanics.

Solution:

• • Implement robust collision detection and physics systems that accurately recognize interactions between objects and the environment.

2. T-Pose Glitch

The T-pose glitch is when character models default to their base position (arms stretched out, standing upright) instead of animating properly. This bug typically happens when there’s an issue with the animation system or when a model’s skeleton fails to load correctly.

Why It’s a Problem:

• • It looks unprofessional and can ruin immersion in narrative-driven or visually rich games.

Solution:

• • Ensure that animation systems are thoroughly tested and that models are correctly rigged. Automate animations to fall back to idle poses rather than default poses.

3. Invisible Characters or Objects

One of the most frustrating bugs for players is when a character, NPC, or item suddenly becomes invisible. This can occur due to rendering issues or faulty asset loading.

Why It’s a Problem:

• • It disrupts gameplay, especially if the player is interacting with invisible elements.

Solution:

• • Regularly test the game’s rendering system across different hardware configurations and make sure all assets load properly during gameplay.

4. AI Pathfinding Issues

Pathfinding bugs happen when non-playable characters (NPCs) or enemies get stuck, take odd routes, or fail to follow a logical path through the game world.

Why It’s a Problem:

• • It breaks immersion and can make the game feel unpolished. In some cases, it makes enemies or NPCs ineffective.

Solution:

• • Use advanced pathfinding algorithms like A* or Dijkstra’s to create smooth navigation for AI. Regularly test AI behavior in complex environments.

5. Infinite Loading Screens

An infinite loading screen occurs when the game gets stuck loading a new level, save file, or asset, and it never completes the process. This can be due to resource management issues or file corruption.

Why It’s a Problem:

• • It prevents players from progressing, leading to frustration and negative reviews.

Solution:

• • Optimize loading sequences, check for memory leaks, and ensure efficient resource management to avoid hang-ups during transitions.

6. Game Crashes

Frequent game crashes are a major issue, especially for complex games. Crashes can result from anything from unhandled exceptions to memory overload or conflicts with a player’s hardware setup.

Why It’s a Problem:

• • Crashes cause players to lose progress, which can lead to frustration and deter them from playing the game again.

Solution:

• • Regularly test your game for stability across different systems. Use tools that monitor memory and handle exceptions to prevent crashes.

7. Texture Pop-In

Texture pop-in is when textures load too slowly, causing a blurry or low-resolution version of an object or environment to display until the high-res texture finally appears. This is usually due to delayed loading or resource streaming.

Why It’s a Problem:

• • It creates a jarring experience, especially in open-world games, making the game appear unfinished.

Solution:

• • Optimize asset loading and streaming so that textures load seamlessly as the player moves through the game world.

8. Floating Objects

Occasionally, in 3D games, you’ll encounter objects or characters that seem to float above the ground instead of interacting naturally with the environment. This can happen due to issues with physics or collision detection.

Why It’s a Problem:

• • Floating objects break immersion and can confuse players, especially in puzzle or physics-based games.

Solution:

• • Implement physics systems that anchor objects to their correct position and continuously test environments for floating assets.

9. Audio Glitches

Audio glitches come in various forms, such as repeating sounds, missing dialogue, or out-of-sync audio. These bugs can arise from poor audio asset management or synchronization issues.

Why It’s a Problem:

• • It breaks the immersion and can interfere with the narrative or gameplay, especially in dialogue-heavy or rhythm-based games.

Solution:

• • Implement audio management systems that ensure proper loading, playback, and synchronization of sounds, especially during high-action sequences.

10. Frame Rate Drops

Frame rate drops occur when the game becomes overloaded with too many processes, causing it to stutter or slow down. This can be due to unoptimized assets, poorly managed resources, or hardware limitations.

Why It’s a Problem:

• • It impacts gameplay smoothness, making it difficult for players to interact or react in time, especially in fast-paced games.

Solution:

• • Optimize textures, reduce polygon counts in complex environments, and test the game’s performance on low-end hardware to ensure consistent frame rates.

11. Soft Locks

A soft lock happens when the player is unable to proceed in the game, but the game doesn’t crash. They might be stuck in a dialogue, in an environment, or trapped by game mechanics.

Why It’s a Problem:

• • It forces players to restart the game or load from a previous save, which can cause frustration and lost progress.

Solution:

• • Test extensively for potential soft locks and ensure that players can always exit or recover from unintended situations.

12. Save File Corruption

Losing progress due to a corrupted save file is a devastating bug for players. This can occur due to improper save functions, hardware issues, or conflicts during the save process.

Why It’s a Problem:

• • Players may lose hours of gameplay, which could lead to uninstalls and negative reviews.

Solution:

• • Ensure the save system is robust by implementing auto-saves, backups, and verifying that save files aren’t corrupted during writing or loading.

13. Invisible Walls

Invisible walls occur when the player can’t move past a certain area, despite the game visually suggesting they can. This is usually caused by poor level design or improperly placed collision boxes.

Why It’s a Problem:

• • It creates frustration, especially if players feel like they should be able to explore freely.

Solution:

• • Use clear visual indicators for boundaries and ensure that invisible barriers don’t obstruct natural gameplay flow.

14. Hitbox Detection Problems

Hitbox detection issues occur when attacks, projectiles, or interactions fail to register correctly. This can happen in both combat and physics-based games, leading to missed hits or broken interactions.

Why It’s a Problem:

• • Inaccurate hitboxes can make gameplay frustrating, especially in competitive or action-heavy games.

Solution:

• • Implement precise hitboxes and conduct regular playtesting to ensure all interactions are properly registered.

15. Glitching Through Floors

Glitching through floors or terrain can happen when the game’s collision detection fails. Players or NPCs might suddenly fall through the ground, which can ruin immersion or trap them in an endless fall.

Why It’s a Problem:

• • This can break the game and force players to restart, which is especially frustrating in games without frequent checkpoints.

Solution:

• • Thoroughly test collision detection and physics to ensure that characters and objects don’t glitch through surfaces.

16. Quest or Mission Bugs

Many open-world or RPG games suffer from quest bugs, where certain missions or objectives don’t trigger, causing players to be stuck or unable to progress.

Why It’s a Problem:

• • Quest-breaking bugs can prevent players from advancing through the story, forcing them to reload saves or abandon quests.

Solution:

• • Rigorously test all quest conditions and triggers, and ensure that any event-driven mechanics work smoothly.
