This Component is part of BG Spline Colliders
Description
Generates positions for Polygon Collider 2D inside the spline.
Parameters
splitMode
The mode for splitting a spline. 1) PartsTotal - use specified number parts for whole spline. 2) PartsPerSection - use specified number parts for each section (between 2 points) 3) UseMathData -use data, precalculated by Math component. Note, you can tweak some params at Math as well
partsTotal
The number of splits for TotalSections mode. The actual number of parts can be less than partsTotal due to optimization, but never more.
partsPerSection
The number of splits for PartSections mode. The actual number of parts can be less than partsPerSection due to optimization, but never more.
doNotOptimizeStraightLines
Split straight lines. Straight lines are optimized by default and are not split, but you can override it with this parameter.
showIfNotSelected
