I found an odd behaviour today that I was able to recreate in the sample platformer in C2.
Basically what happens is that, given a small enough gap, a player running over the gap without jumping hits the opposite edge and travels downwards - but then pops back up and continues on the floor.
To see this in action, just run right. The player should bounce back up and continue on, despite the bottom edge of the box actually catching. One quick fix is to crank the gravity up for the player, but that also affects his jump arcs.
Has anyone ever noticed this before? Is this an issue with Construct or something more fundamental to programming?
