If you use something like blender grease pencil, you can export animations as fbx files. Same idea could be possible with other vector based drawings but vector graphics are not well supported in most engines (except things like Rive). Other than that, spritesheets are still the best.

Perhaps the best joke of 2025, both in substance and in form.

It looks like another Darius Khondji banger of a cinematography.

I’m Starting To Worry This Industry Has No Respect For The People Who Work In It Once your stock options were fully vested, did you sell off all the shares in your humanity?

I wrote this column and I'll just say that the original headline was much meaner. The piece itself, though, is still very angry and very mean, I assure you.

One thing that can be peculiar in AAA games here is that the whole logic and gameplay actually sits on our UI scripting, which is responsible for player and AI actions (no behavior trees). Animations are just triggered by events sent by the manager but don't control the flow of the game.

Not too much, it's not a technical talk. I show a bit our debug ImGui in the emotion talk which gives you clues on the state machine made to implement the game (it's a classic "phase" implementation suited for turn by turn games).
Code in C++ and plenty of node scripting in the Snowdrop engine.

A bicycle for the mind, redux
an interview with Alan Kay, by Judy Schuster
Electronic Learning, April 1994
Q: Looking back to your days at Xerox PARC, and from from your current vantage point at Apple, what do you find most surprising about the way technology is being used in the classroom?

Kay: I think the thing that surprised me is that computers are treated much more like toasters, [with] predefined functions mainly having to do with word processing and spreadsheets or running packaged software, and less as a material to be shaped by students and teachers.

Q: What's the matter with predefined functions?

Kay: Put a prosthetic on a healthy limb and it withers. Using the logic of current day education, we could say that since students are going to be drivers as adults, at age two we should put them in a little motorized vehicle and they will just stay there and learn how to be much better drivers. Now, we would think that was pretty horrible.

But what if we gave the same person a bike? We're not going to feel so badly [because] the bike allows that person to go flat out with his body and it amplifies that. [The bike is] one of the great force amplifiers of all time because it doesn't detract from usβ€”it takes everything we've got and amplifies it.

Most computers today are sold like cars, where as many things as possible are done for you. You don't have to understand how it works and, in fact, you don't have to understand how to think because the most popular stuff is prepackaged solutions for this and that. When you put a person into a car, their muscles wither. You put a person into an information car, and their thinking ability withers.

I wouldn't put a person within 15 yards of a computer unless I was absolutely sure that it was a kind of a bike for them.

I thought about this a lot today. Sad to see how it's gotten so much worse.

It’s probably bad that the future of America’s government pivots on a fight between Lex Luthor and the Joker

Hey! Btw I'm currently looking for my next role. Primarly in game or tech design, or product design if it's outside the videogame industry, or other stuff if you think I can fit. Cheers :)

I love typography, which is why I'll spend 3 hours just cycling through fonts to make sure I selected the right one. This is getting ridiculous.

It’s pretty much all mismanagement. Adopting new tech prematurely? Mismanagement. Changing creative direction in production? Mismanagement. Iterating on content 3+ times? Mismanagement. Adding major features in production? Mismanagement.

Poor planning, failure to follow plans - all mismanagement.

I admit that, to an outsider, making a AAA game may look like shooting a film without a script in a year and then do 6 years of expensive reshoots :D

Interesting thread but yeah it's not that simple to make a model when the industry is not structured for it.

Hmm it does. "Create null from path" allow you to make a shape with a path object in it and link this path as the animation path of another layer (it's the "Trace Path" button).
Or maybe I don't understand what you mean here?

Hmmm it shouldn't be that hard with the "create nulls from path" function no?

Finally played through Sparks of Hope (loved Kingdom Battle) during the holiday and it's a very very interesting game. Not in love with everything here but I admire its unique tactical flavor. The soundtrack is also the best I've heard in quite a while. I'll remember it fondly :)

Mostly for my own work, trying to rationalize and digest what we needed, even if the UX direction around interactors was already set when I joined the project. It helped a bit the designer who made the button sequence system for the food minigame: youtu.be/8nq9CRiloAE

The buttons and handles of Alien Isolation | jb siraudin's blog Interactors are surprisingly hard to get right.

Do you playtest the blockmesh asap or do you wait for a first art pass in this case? (since art can affect a bit the visual clarity of a blockmesh layout)
