Flipbook collision on a paper character

Alundra · May 26, 2015, 12:44am

Hi,
Using the collision mode “each frame” on the flipbook has no effect on a paper character blueprint.
Is it possible to have an update to have precise collision ?
Thanks

Hey ,

Thank you for your feature request, I have submitted this request to our developers. If you need to reference this feature request in the future, please refer to: UE-16269

Thank you and have a nice day!

Hi ! I might be missing something but why did you open a ticket for a feature request? Collisions do work for flipbooks but they need to be on a different channel from anything else inside that blueprint.They go bananas especially with capsule components if they are on the same collision channel. This is a limitation that i had discovered many months ago and it is discussed in the paper2d forum.

I don’t see how make it working, I have the flipbook set but only the capsule is used, maybe can you show an image to solve the problem ?

missed this before going home for the night, but I wanted to follow up and let you know that your original post’s report is connected to the feature request. When it comes to a limitation, it’s hard to say if it’s a bug or a lacking feature, so they went with calling it both for now, just to track it easily.

Nothing would make me more happy if you fix this limitation. It took me forever to figure out and it caused me to change almost all my bp’s for it to work. But as always with paper2d i suck it up, i use the alternative that good old provides me with and i move on to the next challenge. The only reason i told about it was because i wanted to offload some work of your shoulders.

Hey friend,

go to answerhub and search for this issue. You will find a post with my name on it that explains the problem in depth. If you still get stuck hit me up in the paper2d thread and i will try to help.

Hey,

I have heard back from the developers regarding UE-16269. This feature request has been closed as ‘won’t fix’. It’s been stated that a custom character movement component will need to be created if you wish to use a different shape than the capsule for the character. Basically, every 2D game with complex collision uses a different method to achieve their goal for example, 2D Sonic uses two downward traces and two side traces while 2D Mario is set up completely different.

For any trouble with collision for 2D paper characters, feel free to create a new thread, or simply post a question to AnswerHub.

Have a great day!

I simply need collision from the flipbook and one velocity, I don’t find a solution actually to use collision from the flipbook, I searched the post by to have informations but I surely searched wrong because I didn’t find a post about the same problem with a clear answer so actually I use the capsule transformed to a sphere but yea, very not accurate for 2D games.

Hi ,
I’ve been looking for the solution to this problem and have run into your name a few times now. I followed your advice above but looking through your entire history on AnswerHub, I’ve only been able to find this question ( Flipbook collisions do not work with custom collision channels - World Creation - Epic Developer Community Forums ) which doesn’t seem to have an answer. Is it truly impossible to use collisions derived from Flipbook for a PaperCharacter? Is there any way at all to replace the Capsule Collision with a different shape that better fits the character?
