Using Dijkstra Maps

I first read this article on Dijkstra Maps quite a while ago, and discounted it because it seemed that running a recursive formula like that every turn would be too heavy for my game to handle.

However after testing, it worked out to be much faster than a similar process I had developed, and with better results. Only goes to show, don't discount any technique until you've tried it.

Yellow is safe, black is danger.

However, I couldn't get the same results that the author talked about, by multiplying the output by -1.2 if anything the agents seemed to get stuck in the corners even more.

By inverting the results it gets a nice pathfinding technique, though it'll take more testing of that to see how it compares with what I'm already doing.

Automating Level imports from Blender to Godot

Recently I've been making some levels in Blender an importing them into Godot. There are only about 7 or 8 shaders for each level, not counting dynamic objects which will be added later. But to improve rendering performance, it can be a good idea to split the meshes up into sections. At that point you might be faced with a list like this: Or it might be even more chaotic, if you didn't use simple names for the objects in your level. So it can take a long time to sort out all the meshes, make them unique and add textures and so on. Blender imports with simple Blender textures, or with placeholder materials. This is sometimes OK, but if your Godot shaders are very different to those used by Blender, it means applying new materials to every mesh object in the level when you import the scene. I found that during the design process, I was importing and readying a level several times before I was happy with the final layout. So at first I was wasting a lot of time. In Blender, I us

Upstairs / Downstairs.

I've decided to make my prefabs multilevel. Later this should allow me to add pit traps and other great stuff. It also makes it easier to line up stairs so that you can exit them on the same co-ordinates where you entered them. The prefab editor is pretty much finished, it just needs some code for loading up prefabs from a saved dictionary, so that they can be checked or edited. The entries will need to be forwards compatible, so I'll be loading each tile and then translating the indexes to a new array, that way if I add extra indexes or extra info (like traps or puzzles) I'll be able to update existing prefabs to work with the new standard.

Advice needed on tilesets...

I need some advice on which is the best way to handle building the dungeon. Right now I'm using prefabs for my dungeon, they have a north south east and west section for each "room": The basic tileset. This has several advantages, and also several disadvantages. Firstly I can have curved rooms, I can have tunnels and other interesting shapes. The tilesets can look quite nice with a little work. On the other hand I can't easily get the navigation data before building the map and once the map has been built I can't make changes to the layout, like having active pit traps or believable secret doors. Although the rooms are interesting, they are quite repetitive, and it takes a lot of effort to make even a few different variations. Also rooms are constrained to one size. A newer version of the tileset with a lot of variant parts for making more interesting rooms. To create a tile set is a real headache too. Planning how to lay out the UVs, trying to cra
