Dev Log - 3D Car City Game

What got built

• Started turning a simple car demo into a city driving sim
• Replaced endless road idea with a flat city world
• Added building generation across a grid system
• Introduced traffic cars that move in the world
• Added police system that reacts when speeding
• Added basic collision system for buildings
• Started shifting toward an “infinite city” structure

⸻

Key systems working now

• Car movement with rotation and speed physics
• Camera follow system
• Procedural building generation
• Traffic spawning and movement
• Police spawn when speed limit is broken
• Basic collision response with buildings

⸻

Problems found and fixed

• Car could drive through buildings due to weak collision checks
• World ended after a fixed area instead of continuing
• Some code errors broke building generation and movement
• Traffic was too random and not structured like road behaviour

⸻

Next planned upgrades

• Proper infinite city chunk loading
• Road and lane system inside city blocks
• Improved traffic AI (lane following instead of random movement)
• Car models instead of cubes
• Police improvements (sirens, chasing logic, stopping system)
• UI system (speedometer, cash, fines)

⸻

Current state

Playable prototype, but still early stage:

• You can drive around a city
• Collisions partially work
• Traffic and police exist but are simple
• World generation is now being upgraded to infinite streaming
