Platform Behavior bug (gliding over platforms)

Bugs will be moved here once resolved.

Post » Sat Dec 15, 2012 10:11 am

This has actually been around since day 1, and was even a problem in CC, but got much worse in C2 r112.

If you are jumping and move on to a platform horizontally - often when pushing up against it - there's a chance that your player won't land but instead get stuck in a sort of jumping/landing limbo. The only ways to get out of it are to jump again, walk off the platform, or stop moving horizontally in which case the player will do a short "hop" that is actually the remainder of the previous jump.

Here is a .capx to easily reproduce this bug.

The player is yellow when on the floor and orange when not. Just hold right and jump to that higher platform while moving and chances are you'll "land" but remain orange.Tokinsom2012-12-15 10:22:03

I came here to post the exact same thing. My issue doesnt have the hop thing tho, maybe its not noticeable because i set low settings on the platforming. Anyway, thanks for reporting :D

The platform movement is getting insanely complicated, but I think I've been able to resolve it for the next build. Let me know how it goes...

I did many workarounds on my platform game to avoid various issues, and every time We earn a new solution I need to rework the whole code to find where my workaround stopped to work.

Hope the next patch solve it in definitively.

Hello, I have the same issue.

I'm using release 114 (64-bit).
When I jump onto a platform and the jump and the jump movement is not finished yet and you then touch the platform the character slides to the left or right.

I tried several options to stop this, but the only thing helping is if the player pushes a key to stop the movement.

Searched the tutorials and the forum but didn't find a satisfying answer, the issue is best simulated with a low jump strength.

@Ashley Sorry for the late response. This bug occurs much less frequently as of r113/114, and is very difficult to reproduce in the example now, but unfortunately it still happens from time to time in my other projects.

Actually this may have introduced another bug (it may just be my code, I'll look into it) where your player is pushed upwards a few pixels after stopping on a slope. I never had that happen before r113 so..Tokinsom2012-12-29 02:44:50

Can anyone reproduce this in a reliable way in r114? The Platform behavior is very complex, and it's extremely difficult to do anything about issues that happen rarely.

Ok, I modified my game to reproduce those bugs. I found another platform bug, I call him "floor bug". If u look the video, when the player goes over the junction platform floor, depending on the position, it consider like the player is landing... but he's running without jumping.
I sended modified capx directly to support at scirra, because last version I was working on (r110.2) it works fine. From version r111 I begin to have those problems...
I modified the collision polygon of the grass to better show the issue. The arrows represent the keyboard commands.
Here's the videos (not in public list, of course!):

Hope you fix it like in previous version.
