bevy_ecs_ldtk VS jumpy

Collision detection - no auto-generated, you build your own manually. The LDtk integration has lots of examples here. Note that for 2D, if you only want rectangles bordering sprites, you can set the collider bounds equal to your sprite bounds, which gets you 99% of the way there

I've really enjoyed using ldtk for this kind of thing using this plugin https://github.com/Trouv/bevy_ecs_ldtk. The bevy setup for entities and collisions is a little verbose but there are solid examples in the repo that I was able to get working in my project very quickly by building from that code. It's pretty activity maintained and they've been responsive to bugs I file too.

However, I'm struggling with adding collider boxes to entities. In ecs_ldtk example (https://github.com/Trouv/bevy_ecs_ldtk/tree/main/examples/platformer) they spawn colliders automatically attached to entities. However, I would prefer to have them be slightly shifted (let's say, only 1-tile-sized collider attached to the player's legs or no collider on a tree crown), which means I need to spawn a child anchor to the entity and attach a collider to it. I guess one possible solution would be to have a system that does this for me on entity spawn, but maybe there's another solution I'm unaware of, and more experienced developers could help me here. Thanks in advance! :)

I made a 2D platformer randomization crate called Shiftnanigans (https://github.com/AustinHellerRepo/Shiftnanigans) as part of my work on the open source game Jumpy (https://github.com/fishfolk/jumpy). Within the map editor of Jumpy, the Randomize button will randomize the placement of tiles and elements, maintaining the general structures of the map. I've described the two abstract concepts and sets of structs used to accomplish this functionality below. This is just a general overview, but I am happy to elaborate further if anyone has questions about the algorithms and data structures used.

Since late September we've been rewriting 'Fish Folk: Jumpy' in Bevy, headed up by Jumpy's new lead dev zicklag. With the release of v0.5, we now set our sights on a crowdfunding campaign due to launch in early 2023.

Thanks for this! We have a longstanding idea to use WFC as a way to create procedurally (re-)generated maps for our 2D platformer game. Happy to collaborate further on this if you’re interested.

Also the people from Katharos are great contributors of Bevy itself and also is working on Jumpy, which is a great source of inspiration and showcase for community, which doesn't uses Katharos License.

Fish Fight is developed in Rust.
