Roblox Curve Script

--Minis Curve Creating Script (UnderDev)
--https://developer.roblox.com/en-us/articles/Bezier-curves
-- T is a decimal below 1, 1 means curve is completed
--So smaller intervals means more points and smoother creation
--P1 Is midpoint
--P0 and P2 are the start and finish
--Uses Pythag and current position + %Complete
--V1
