  • How To Report Bugs

    - Leszek Gorniak

  • Reproducibility

    This indicates whether a bug always occurs when Steps to Reproduce are performed or whether it's not recurrent or in some way difficult to track. In a perfect situation, before reporting a bug we should always come up with such Steps to Reproduce that always result in the bug, but in some cases it will not be possible (for example bugs connected with low performance are sometimes difficult to reproduce).


    Not always required, but sometimes necessary. Examples:

    • game is developed for e. g. PC, PS4 and XBox, and the bug occurs only on one of those platforms
    • the bug is related to low performance, so we need to report an exact hardware configuration
    • game is developed for web browsers, and the bug occurs only in a specific browser


    Those could be:

    • screenshots (very useful when describing bugs related to environments and UI)
    • videos (could illustrate some strange AI behaviors)
    • error logs (in case of any kind of crashes they should be considered a complementary part of the report)

    OK, let's see how the bug descriptions listed at the beginning could look like with the bug template applied.

    Example 1: Cave Troll cannot be defeated with some weapons.

    Title: Great Axe doesn't do any damage to Cave Troll
    Category: Gameplay
    Severity/Priority: Critical/High
    Steps to Reproduce

    2. Travel to the Dwarven Realms
    3. Talk to Ghotrek to activate the Cave Troll side-quest
    4. Go to the Cave Troll's lair
    5. Equip any weapon of Great Axe type
    6. Attack and try to damage the Cave Troll

    Current Result: Cave Troll receives no damage
    Expected Result:
    Affected Version: 0.3.1
    Reproducibility: always
    Platform: any
    Attachments: N/A

    Example 2: HUD displays incorrect amount of ammo.

    Title: Too much ammo is added after reload
    Category: UI/HUD
    Severity/Priority: Major/High
    Steps to Reproduce: 

    1. Equip any firearm (let's assume it has 30 bullets in the clip)
    2. Fire 5 bullets
    3. Reload

    Current Result: HUD displays 55 bullets loaded (amount before reload + clip size)
    Expected Result: HUD should display 30 bullets loaded (amount before reload + 5 after the reload)
    Affected Version: 0.3.1
    Reproducibility: always
    Platform: any
    Attachments: screenshot with incorrect value marked on HUD

    Example 3: Graphics in level 3 is broken.

    Title: Skyscrapers in level 3 don't have materials applied
    Category: Environments
    Severity/Priority: Minor/Normal
    Steps to Reproduce:
    Current Result: please see attached screenshot
    Expected Result:
    Affected Version: 0.5b
    Reproducibility: always
    Platform: PS4
    Attachments: screenshot with Skyscrapers

    Handling bugs in an organized and consistent manner is essential for game quality. Using a clear and unified bug report template will boost your communication and team performance and, in the end, help deliver a smooth game experience that the players expect.
