BezierPath, an easy to use and optimized spline path module for TD games and general paths

Intro

BezierPath is an easy to use bezier spline module, designed to be used for TD games and general paths while being optimizied for large scale uses.

Code example

local BezierPath = "Path to the module"
local Positions = {
    Vector3.new(0,10,0),
    Vector3.new(10,0,0),
    Vector3.new(10,10,10)
}
local NewPath = BezierPath.new(Positions,3)
local Part = Instance.new("Part",workspace)
Part.Size = Vector3.new(1,1,1)
Part.Anchored = true

for t = 0,1,1/100 do
    Part.CFrame = NewPath:CalculateUniformCFrame(t)
    task.wait(0.1)
end

Optimization

Here is BezierPath against the old module i used for my TD game calculating uniform positions


(function1 is BezierPath)

now i can torture myself by makin cutscene with this,…,.,.,.,

this module probably wouldn’t be the best option, id recommend catrom for cutscenes as its alot more smooth. unless you want to use this module’s behavior for cutscenes

nah there’s already a cutscene module with bezier path, just need it for lerpin models like helicopter

I’ve been meaning to make something like this for a long time now and now this saves me the trouble! Sweet.

Can you add a function that given a distance d it finds the position of it along the curve as example

arcLenght = 5

d=2.5

the point would be on the middle. This would help me on a project I am doing.

I’m pretty sure this is already possible, the T in uniform CFrame/Position methods is an alpha value. If you give it the value of 0.5 it will be in the middle of the path.

You can easily translate a distance value to a T value. In the module i made a function called :GetPathLength()
it returns the splines total length. With this you can easily get the needed T value by just doing
local T = Distance / PathLength

Someone else answered, but what you did there is getting the distance based on a tvalue, not the other way around

omrez, i am truly thankful for this amazing module bestowed unto me by the powers of total, peak roblox programming, in which leaves me bewildered as its beyond my puny understanding

Question, I might be dumb or so or I just can’t happen to be able to set it up right but for some reason it error that “new” is not a valid member of the module… Should not happen since .new() is literally a function in the module.

2 Likes

are you requiring the module correctly? i see 0 reason for it to say .new does not exist apart from that reason

Oh god im so stupid… I always forget to actually “require” it sorry for the time I wasted you. Thx for the help tho
