[2.2.13] Knuckles Climbing Oddity.
Horizon Effects, No-Climb Flags and Sky Barriers are normally not climbable... but in some cases you can climb onto these without any issue... to a point. Sometimes you can attempt to climb them and either it works or it'll kick you off after a few ticks or you'll need the aid of a nearby climbable wall. A rundown...
Horizon Effect
You can't climb these walls normally by just gliding into them, however... if a neighboring climbable wall is near and the wall angle is still the same as the Horizon Effect, you can climb across it. If you're near the climbable walls... you can climb across the Horizon Effect Wall.
Wall Sector with No-Climb Flags
You can't climb these by gliding into them though if a neighboring climbable wall is near and the wall has the same angle... you can climb across it. If you're near the climbable walls... you can climb across the No-Climbs.
Sky Barrier
You can't climb these by gliding into them and even if a neighboring climbable wall is near ... you still cannot climb across them... though for some reason if you climb near the climbable walls... you will attempt to climb them but then fall off after a few ticks. Repeating this will let you climb up them.
Middle Wall with No-Climb Flags
You can't climb these by gliding into them though if a neighboring climbable wall is near and the wall has the same angle... you can climb across it.
