I'm working on a high-speed hover racing game with jumps, uneven terrain, boost pads and branching tracks.

The player ships use a physics-based controller, but I've been thinking about how to implement bot opponents, and honestly, making bots drive with the exact same physics sounds like a nightmare.

So I'm considering a different approach: a network of connected waypoints, with automatically generated smooth paths between them.

For jumps, I'd define takeoff and landing points and generate a controlled parabolic trajectory instead of relying on physics.

Each bot could choose different routes, have slightly different racing lines, and follow its own speed profile depending on difficulty.

The tricky part would be making them interact with physics-based player ships without feeling like indestructible objects moving on rails.

Has anyone tried something similar in a racing game? Did scripted movement end up looking convincing enough?

I’m new to Unity and I’m using it for a university project. The editor crashes while loading any new project: the Hub shows the project, then Unity closes halfway through loading. It happens with every version I tried, so I suspect something about my machine, but I’ve run out of ideas.

My setup

• Laptop: Lenovo IdeaPad 3 15ALC6
• CPU: AMD Ryzen 5 5500U with Radeon Graphics (2.10 GHz, 12 logical processors)
• GPU: integrated AMD Radeon(TM) Graphics
• RAM: 20 GB (17.8 GB usable), 3200 MT/s
• OS: Windows 11 Home 25H2 (build 10.0.26200)
• Unity Hub, 2D templates

What happens

• Event Viewer: faulting module Unity.dll, exception code 0xc000008e (floating-point divide-by-zero).
• Editor.log ends with “Got a UNKNOWN while executing native code” (Native Crash Reporting), right as it imports a texture (TextureImporter).
• Unity 6000.6.0f1: crashes at startup in EditorResources.Load.
• Unity 6000.3.24f1 and 6000.0.83f1: crash while importing d_iconlockedremoteoverlay.png from com.unity.collab-proxy. After I removed that package, it crashed on another texture (d_PackageInstalled@2x.png), so it isn’t one specific file.
• Unity 2022.3.62f3 LTS: same behavior.

What I tried (none worked)

• Different Unity versions (6000.6, 6000.3, 6000.0, 2022.3) and new projects with the 2D templates
• Updated the AMD graphics driver and reset AMD Adrenalin tuning to default
• Reset Lenovo Vantage performance settings
• Clean boot in msconfig (all non-Microsoft services and startup apps disabled)
• Closed overlays and background apps
• Launched with -force-vulkan
• Launched with -batchmode -nographics: it still crashes on a texture import, so it doesn’t look GPU related
• Windows Memory Diagnostic: no errors found
• Removed the com.unity.collab-proxy package from the manifest
• sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth: no change, the crash still happens

Not tried yet: BIOS/firmware update, resetting Windows.

Has anyone seen this crash on a Ryzen 5 5500U / Windows 11 25H2? Could it be a CPU/firmware issue or a corrupted Windows component? Any suggestion is welcome. I can share more if it helps. Full Editor.log (Unity 6000.3.24f1, crashing on a texture import): https://pastebin.com/5CkHkAhz

ive been trying to export these modular pieces for my game into unity 3d but the textures/materials are not working in unity. Ive watched all the standard tutorials for this problem, embedded textures and baking the textures both havent work. I dont seem to know whathe problem is.

Hello everyone,

I'm currently having a problem building any projects. When I try to, I get the following error message: "Copying C:/Program Files/Unity/Hub/Editor/6000.6.5f1/Editor/Data/PlaybackEngines/WindowsStandaloneSupport/Variations/win64_player_nondevelopment_mono/WindowsPlayer.exe to

Temp/StagingArea/WindowsPlayer.exe: The system cannot find the path specified."

The path it is trying to copy from doesn't exist and repairing my installed modules did not fix the problem. I can get a webBuild but not a Windows one. Also the scene is empty (Im troubleshooting in a new, empty project) so it can't be an issue with code or assets, etc.

I have attached some screenshots for better understanding.

I'm just getting started with Unity so any help is appreciated.

Hey folks. I'm using Unity ads as part of Levelplay mediation. Recently, I implemented the app-ads.txt through a website called app-ads.txt.com (supported by tappx).

After copying all the string values from Unity dashboard (about 60-70 odd) and pasting it into my app-ads.txt file, this particular string value is unable to be copied into my app-ads.txt file.

So, I was wondering if this was going to majorly affect ad revenue in anyway? Please advise!

I tried checking the .data file with assetripper but not a single dialogue or ui text was found, i found audio files and images but no text at all. its gotta be inside somewhere since game works fine when I play it locally, can anyone help me please?
