Function
Synopsis
x, y = BezierCurve:getControlPoint(i)
Arguments
number i- Index of the control point.
Returns
number x- Position of the control point along the x axis.
number y- Position of the control point along the y axis.
Example
Get position of all control points
local count = curve:getControlPointCount()
local vertices = {}
for i = 1, count do
local x, y = curve:getControlPoint(i)
table.insert(vertices, x)
table.insert(vertices, y)
end
