I asked Gemini to write code to park a car in a simulation I made.
For anyone curious...
this is using Gemini 3.1 Pro.
Prompt 1:
[var1] = Parking Simulation
[var2] = InitializeParking
[var3] = gemini_v1
use the documentation at: https://github.com/theaia/AIGamePyLibrary/tree/main to create a python script for the [var1] . Use the details of the [var1] to create a viable AI for whatever strategy you deem appropriate. Make sure to select cosmetic options for [var2] that represent your vibe. There are countries for popular LLM models you might associate with. You can leave the custom_texture empty. Make sure the modifier LLM is set to true.
Use the name "[var3] "
Use the name "[var3].txt" for the save data
Summarize your strategy.
Prompt 2:
this is pretty good. the only issue it has is that it gets into a loop when it has a forward collision detection where it just keeps going forward and backwards.
I'd recommend adjusting your strategy to...
# 2. Custom Throttle: Drive forward if clear, reverse if obstacles are detected via raycasts.
for what happens when obstacles are detected. just reversing and then going forward when clear is resulting in a continuous loop of collision
Prompt 3:
this solution is slightly better than the last version, but still has the same problem where it's getting stuck in a continuous forward/reverse loop where there's a forward collision.
It appears that the steering correction in reverse doesn't occur for a long enough duration to allow the car to adjust it's heading meaningfully enough

Prompt 4:
this is better, but the front right of the car ends up colliding with another car. perhaps your spherecasts need to be wider to account for this.

Prompt 5:
this is pretty close here's what I noticed...
-the car seemed to prioritize alignment, this resulted in a case where the car was successfully in the stall but decided to reverse out of it. ParkingGetBool has an option to allow you to see when you're fully in a stall
-pulling into a stall will result in a forward collision because of the curb. you may need to prioritize ignoring forward collisions when the target is closer than the forward collision
-the car collided when reversing to adjust it's heading. perhaps rear collision detection would help
