How does the entirePath function cope with variables in curvy
Hello,
I try to make cake pieces out of a circle with defined gaps between the cake pieces. The amount of pieces depend on what the user entered as number:
Below you see what I have. It makes cake oeices, but the connection between starting segment and ending segment is a straight line. Jongwares collection says:
entirePath:
A list of the coordinates of all of the path points on the path, including anchor points and left- and right-direction points. When creating a path using this property, supply either a list of anchor point coordinates ([[x1, y1], [x2, y2], ...]) or a list of anchor point, left-direction point, and right-direction point coordinates ([[[x1, y1], [x2, y2], [x3, y3]], [[x4, y4], [x5, y5], [x6, y6]], ...]). Note: Providing only anchor points results in a path on which all of the path points are connected with straight line segments; supplying the positions of left- and right-direction points specifies curved line segments. Can return: Array of Arrays of 2 Units.
I understand it like this:
if I want to have a straight line, you just give coordinates single points composing of x and y
e.g. for a triangle
var path = entirePath([ [x1, y1], [x2,y2], [x3,y3] ]);
if I want to have one curved line, you need to add the coordinates of the ends of the right and left handle to the points composing of x and y
e.g. for a triangle
var path = entirePath([ [x1, y1], [x2,y2], [ [x3_1,y3_1], [x3_2,y3_2], [x3_3,y3_3] ] ]);
Now I wrote in my example the variable myPath in line 62. And I get an error message marking line 63 "entirePath", no other information, I have no clue were the mistake is.
So if anybody has an idea were my mistake is, I would appreciate the help.
Best
