Bevy EntiTiles 🗺️

A tilemap library for bevy. With many algorithms built in.

Strongly recommend that you take a look at the bevy_ecs_tilemap library first. I took this crate as the reference and learnt the basis of bevy rendering.

This repo is under maintenance as long as this message exists. ( Hope this message can bring you peace of mind. Yeah, that's childish :p )

Notice that the following progress may not up to date. Check the README.md in dev brach to get the latest progress!

Currently Working On

• SSAO & Volumetric Clouds / Fog

Future Goals

• Wave Function Collapse ( Optimization )
• Pathfinding
• Tilemap-Link
• Runtime Mesh & Texture Baking
• Tilemap Serializing
• Chunk Unloading
• SSAO
• Volumetric Clouds / Fog
• Wang Tilling
• Tilemap Mask
• Frustum Culling ( Isometric Specific Optimization )
• Physics

Known Issues Currently Unresolved

• The success probability of the wfc algorithm significantly decreased after switching to LookupHeap. ( And that's the reason why I didn't switch to LookupHeap )

Performance

Platform: 10600KF

Frustum Culling

Bevy 0.11.3, crate 0.1.1, 1000x1000 tiles

Pathfinding

The pathfinding algorithm is very fast.

Notice this tests are done with synchronized pathfinding. Which means whole algorithm will figure the path out in one frame. But since 0.2.1, we the supports asynchronized one. The algorithm can complete a part of the pathfinding and continue it in the next frame. This will make it even smoother.

Bevy 0.12, crate 0.2.1, using pathfinding example

Wave Function Collapse

In the following case, each tile has at least one corresponding color gap with its neighboring tiles

Column 1: Bevy 0.11.3, crate 0.2.0, NoneWeighted; Column 2: Bevy 0.12, crate 0.2.1, NoneWeighted, max_retrace_factor = number in parentheses
