Unclear about angle orientations about pathplanner HOT 11 CLOSED

@minglethepringle I think the misconception is because of the second issue; the angle is actually measured counter-clockwise, until you get to ±90, ±180, ±270, ±360 or 0; they are (for some reason) the same angle. @sriharis123's point still stands in that this is a problem with the Pathfinder libraries and not the UI.

They are the same, there is no discrepancy between them - what the graph shows is what you'll get

I believe this is an issue with the libraries that are used by this generator (Jaci's Pathfinder), and not the generator itself. I may be wrong.

@sriharis123 I'm afraid that because of this issue, my trajectories are wrong :(

from pathplanner.

@Endoman123 it displays correctly on the graph, but do you think the trajectories would be generated accurately, even with the "incorrect" angle?

from pathplanner.

@minglethepringle AFAIK it should be fine; from my own personal experience with using the Pathfinder library, it has not affected the path.

Best way to check is to generate a CSV and look through the trajectory points in some kind of table viewer

@Endoman123 alrighty, thanks!

This is a bug due to how Pathfinder treats angles that sit in specific locations on a circle, depending on the slope angle between the waypoints. Basically, if you plot a straight line between two waypoints, the angle of either waypoint is calculated as an offset from this angle. This adds the constraint that you can't have a perpendicular exit angle, since this is tan(90) which is inf. This also means any angles over 90deg with respect to these two lines will not be signed.

This is being fixed in V2

@JacisNonsense Will my trajectories still be generated accurately, as shown by the generator?

from pathplanner.

What do you mean? The display in the generator is the trajectory, they are one in the same

from pathplanner.

@JacisNonsense Because I specified -90° instead of 90° because they displayed as the same; I don't want my trajectory to be shown pointing left and generated pointing right or something.
