@gators1 said in The OFFICIAL programming thread:
Flow graphs are pretty common in the data world as well. Our data movement tool, informatica, uses them at a couple levels to define the mapping of one column to another column and the process of when to run mappings in sequence. It is funny though how such tools often complicate something you could do easily in code. We ended up using a ton of SQL overrides in the ETL because we couldn’t be arsed to spell it out with all the boxes and lines, or in some cases you couldn’t even do it the way we wanted it.
I have something similar to your OR problem quite often actually. Our report creation tool, which is basically a SQL GUI can’t easily do the order of operations in the equivalent of the WHERE clause. So I get tripped up when I want to do something like WHERE (A=1 AND B=0) OR (A=0 AND B=1). It has AND and OR but to create the parentheses I have to create new filter objects with the AND conditions, which is a different GUI, and then use those objects in the report definition. It’s not a huge inconvenience as you can create them pretty quickly, but it does tend to clutter up the application when you have to create a bunch of these and you have duplicates over time.
… And it can’t just do where A!=B?

No because A could be 2 and B could be 3. The point is that in general you have to do the operations in parentheses in a different way than the rest of the where clause in the GUI. So it makes it harder to do complex where clauses than with just coding.

@gators1 Cool video. It’s amazing how clean and uncluttered todays mobo’s look compared to the first one I bought back around 1991 when I first assembled a PC.

Can I get in on early alpha? How much for one of the streachy green guys?

That’s an NFT. Only 10 billion will be minted so I can’t let them go cheap.

I can’t believe I’ve spent a week on this and without a satisfactory result. I mean, I’ve got it to a point where it’s way better than the above but it’s still not usable. To get to the point I’m at now, I’ve had to by trial and error and process of elimination:
- Discover a bug in the engine (already reported on Github) and code around it
- Discover that the documentation is not only wrong but actually misleading and caused half the problems in the original vid
The whole ragdoll physics feature in Godot is woefully undercooked which explains the dearth of internet resourses around it - ie no one is using it.
Anyway, as frustrating as it’s been. I’ve learned a bunch of stuff and the only thing I’ve lost is personal time. Hardest part is that I’m left without a solution that doesn’t require a major and costly change in approach.
This type of problem, although not common, terrifies me when it happens on a paid gig. It’s so fucking hard to explain to project managers and stakeholders what the hold up is and you feel like an incompetent idiot.

Well this will do. I’m not Rockstar Games and I’m not making an AAA title. There’s still some occasional mesh tearing issues but I’ll wait until I have the actual higher-poly game assets before I try and fine-tune it further.

You should team up with Jerraye and make an indie studio!

Tigger could do the ai too! And Doc will be player relations because he’s great at that!

I like the:
“Nail Gumby’s Feet to the Floor”
version better!

I’ll stick this here if you’re interested in rewiring a microprocessor.
“The first chips to use copper interconnects, which were produced in 2000, had 1 kilometer of wiring per square centimeter. Today’s 14-nanometer-node processors contain more than 10 km of copper wiring in the same area, she said.”
Graphene Could Buttress Next-Gen Computer Chip Wiring
Current can literally blow copper interconnects away, but graphene could keep them intact

Kind of related: something like 10% of all of the world’s energy consumption is used for computing and that fraction is growing all the time. Apparently half of that energy is consumed (actually wasted) by things like that copper wiring.

Photonics is gonna be great.

Just had the most frustrating week of coding I’ve ever had getting the below procedural floor plan generation working. It sounds so simple but each room needs to have its own walls and I needed to get the doorways lined up between the different rooms. After I’d rewritten it literally 5 times and still couldn’t get it to work I remember thinking it’s just too difficult. Another couple of rewrites with different approaches got me there though.
It’s just a rough first cut. There are too many doorways etc etc. But it is satisfying seeing the enemies hit and slide down the walls with the rag doll physics I implemented earlier.
