The Ultimate Guide to Writing a "Drive Cars Down a Hill" Script in Roblox Studio

Your must compute the net force along the car’s forward direction, then update velocity and position accordingly. Most game engines provide built‑in gravity, but you still need to apply additional forces to achieve realistic hill descent – especially if the car uses custom suspension or wheel colliders. drive cars down a hill script
