[r127] Jump-Thru behavior bug

Bugs will be moved here once resolved.

Post » Mon Apr 29, 2013 8:01 pm

Link to .capx file (required!):
https://dl.dropboxusercontent.com/u/2383513/jumpthru.capx

Steps to reproduce:
1. Create a object with a platform behavior
2. Create a tiled background with a jumpthru behavior
3. When the platform object is falling, go into the platform with the jumpthru behavior

Observed result:
In this .capx the object stops for a moment then resumes the falling, but in my game the character simply stops and walks in the middle of the platform.



Expected result:
There should be no stopping at all, if an object with a platform behavior isn't at the top of the platform he should never stop.

Browsers affected:
Chrome: yes

Operating system & service pack:
Windows 8 64-bit

Construct 2 version:
r127 64-bit

I have been getting similar issues for the last few builds, seems to happen to me when I have jump throughs that are thick. It seems like it has a set height that it expects to use for the platform and if you use one that is thicker than that, you get some issues where it seems to detect that there is a solid platform underneath the jump through. This usually happens to me with jumpt through sprites where I run off the edge then immediately turn back the other way (back toward the platform) and my character will catch in mid-air just under the edge of the platform for an instant. Maybe not as bad as your issue, but still seems to be related.

It's almost as if the jump through has some type of invisible semi-solid platform directly beneath it that you can get caught on some times.

Happens in IE for me...BluePhaze2013-04-30 01:24:11

It should be easy to work around. Just make the jump-thru a thin bar along the top rather than a giant thick block. Still, I'll see if this can be fixed from the platform behavior.

Thanks @ashley!

I've been thinking about doing that too, having a layer full of invisible platforms. Still, if I didn't have to it would be great. Thanks!

I find that when the platform is thin, the character can sometimes teleport through it when the framerate fluctuates or if the character moves too fast iirc.

I'm having the same problem, where it pauses momentarily part way through the fall. Making the platform a thin strip didn't help.

It just got worse with 135 - though I had to finish a project and stayed on 132 until it was finished. I keep getting stuck walking into jump thru platforms from the left or right. I haven't had any issue until now. Been building the game this way since March - not one issue. Now any level with jumpthru platforms is completely bugged. Awesome...damainman2013-06-26 00:16:47

@damainman Could you explain a little better? I tested here and it works just fine, the only bug I have is the one mentioned in the first post.

Maybe your problem has to do with the collision polygon, I had some trouble with the platform behavior until I messed around with it a bit.andreyin2013-06-26 00:53:24

@andreyin Sure! I have platforms set up at multiple heights. Like steps. So some of them will come up to the knees of the player sprite or to his chest - whatever.

If I have one overlapping another for the appearance of stairs or steps that you can walk past or jump onto, the player will get stuck upon touching the second platform no matter what the height. The controls will stop responding. Also I've noticed since 132 enemies that bump into walls or even the player when he's knocked back will now get stuck in/sink through the platform tile. The zombies for example will just bang into the wall until they eventually slide through the ground/platform tile... This didn't happen pre 132 build. It just keeps getting worse and worse.

I'm back on 132 and the getting stuck on the platform issue is now gone. So there is something wrong between 132 and 136.

Also I get this stupid thing if the platform isn't a small strip, the player will kind of hang for a second before doing a complete jump past a platform... I'm going to go back as far as 126 and see what happens. I'm not using any features since 120 anyhow haha!

The detection for platform/jumpthru is completely bugged.

@damainman - post a new report, following all the guidelines, otherwise we can't provide any help.
