studying the tpt2 coaster builder as a beginner dev

been picking apart theme park tycoon 2 lately, not to play but to learn. the coaster builder is genuinely one of the most impressive systems on roblox and it gets zero credit. youre placing spline track piece by piece with banking control, and the supports auto generate underneath to match the terrain height. then the ride cam rides that spline perfectly smooth. think about what that takes, interpolating cframes along a curve every frame without the whole thing juddering or clipping. and it stays performant even on a fully built park with hundreds of parts. as someone still fighting with basic cframe math, this is humbling. i keep opening it just to trace how a placement system should feel, snappy, forgiving, no lag. this is the game that made me want to actually learn the math instead of pasting free models.
