"Grass cutting tasks" get automatically cancelled when the grass dies out. I had to make some big upgrades to my ECS implementation for this to work properly

@lisyarus@mastodon.gamedev.place avatar

@elitihak Well, I wanted to do it by specifying a child-parent relationship between the task and grass entities (child gets destroyed if the parent is destroyed), but I didn't want to hard-code this logic into the ECS itself. My ECS has support for constructors and destructors (functions called on entities matching a specific set of components when the entity is created/destroyed), and support for per-world singleton objects (intended to be used as e.g. search acceleration structures, etc).

Your daily reminder that in almost all aspects of technology (and probably life as well) the answer to any question is not one of the fanatical "die on this hill" extremes, but a boring and unenlightening "it depends".

I've mostly settled on how the first iteration of villagers' AI should work, now prototyping a "harvest" tool that selects all entities eligible for harvesting (the red arrows are temporary ofc)

I accidentally left the simulation for a long time and it converged to a very cool dynamic equilibrium with two species only contacting at a single spot and neither of them winning

I'm at this stupid stage of the project when I can't randomly prototype anymore kuz I have specific plans, but I don't have a solid foundation to work with yet, so I have to invent it on the way, and it's hard.

Still, I'm making progress. Here's some grass spreading mechanic :)

@efi Ugh, just need to figure out how to map all the mechanics into my specific ECS implementation

Felt like having some energy for cooking again. Here's some pasta with mushrooms in a cream+parmigiano sauce, and chicken fried in tomato sauce with carrots and buckwheat.

how do I remove the changes to a file a single commit made in the middle of the history?

lisyarus,
@lisyarus@mastodon.gamedev.place avatar

@efi If there were no changes to that file after that, you can do

git checkout <last-good-revision> -- <path-to-file>

Otherwise the only thing I can think of is

git revert <bad-commit> --no-commit

and then discard all the changes that don't touch your specific file

@efi Hmmm wdym "which side"?

@bug Hi! I wrote a very similar thing about a year ago, thought you might be interested: https://lisyarus.github.io/blog/posts/exponential-smoothing.html

lisyarus,
@lisyarus@mastodon.gamedev.place avatar

@bug Yep, I was planning to mention expm1 (which is also more precise) but decided the post is already too long :)

The thing wiki mentions is actually the same as in my article: if you divide a thing by e = 2.71828, you get 0.3678 of the thing, or 36.78%, meaning you got closer to zero by 100 - 36.78 = 63.21%

I am excited to finally share our recent paper "Filtering After Shading With Stochastic Texture Filtering" (with Matt Pharr, @marcosalvi, and Marcos Fajardo), published at ACM I3D'24 / PACM CGIT, where we won the best paper award! 1/N

@aras @BartWronski "a sensible application of a theory that has not been formulated yet" is pretty much all particle physics since 1950s 😄

"Lambda expressions are objects - their types are classes, so we can inherit from them too."

@niconiconi @whitequark Imo this trick combined with lambdas is the closest we have in C++ to pattern-matching on sum types

I need to get my mind off the bad. Anything good going on tonight for anyone? Feel free to share things your excited about or happy about or just cool stuff you've come across recently

@aeva Returning to my passion game project, doing much more detailed planning this time, have an exciting feeling that I'm slowly learning how to organise work for such things, and generally happy to by working on this again.

Also kinda got used to walking every day around the apartment complex where I live, there's a river and trees and omg so many birds! One I haven't still identified even.

I'm slowly returning to the development of my village building game, and what's a better way to do that other than making a new devlog! :3
