Program AI cars that use a simplified version of your downhill script – they only need to follow a spline path and apply brake/steer based on upcoming slope changes.
In Unity, standard WheelColliders can become unstable at extreme speeds on inclined surfaces. This script applies custom downward force (fake gravity) and uses a Rigidbody to ensure the car stays grounded until it hits a major jump.
You start with "rust buckets" or slow sedans and eventually unlock specialized "whips" like police cars, minivans, or even admin-level vehicles that can practically fly. Environments:
public float motorForce = 1500f; public float brakeForce = 3000f; public float gravityScale = 2f; // Extra pull downhill public LayerMask groundLayer; drive cars down a hill script
Ensure the ramp is long enough to let vehicles gather significant momentum. Placing the Spawner Zone Insert a new at the top of the hill. Scale it to fit a vehicle (e.g., Name this part SpawnPlatform .
import turtle import math
if (!isGrounded) return;
A workspace Part named SpawnPart positioned at the top of your hill.
ALEX (To camera/passenger) They said it couldn't be done. They said the brakes would fail. They were right.

Do you need help configuring a (like A-Chassis or Endorse) to make the vehicles fully drivable? Share public link
To make a car driveable, a script must be assigned to the vehicle; a standard VehicleSeat does not move the car automatically. For a "downhill" specific game, the script should focus on: You start with "rust buckets" or slow sedans
triggerPart.Touched:Connect(function(hit) -- 1. Check if the object that touched the trigger belongs to a player local character = hit.Parent local humanoid = character:FindFirstChild("Humanoid")
: For multiplayer games, run this script on the server (or use a LocalScript with RunService.RenderStepped for client prediction).
