structures byval for params and returns so it's compatible with c, libs like chipmunk, raylib, miniaudio


+1000, so much this. I was actually writing a reply to IceSoft's structures by pointer request as you posted this.

Returning/receiving structures by-value C ABI style would be an ...

Edit: I just found out that the accuracy of the calculation is highly dependent of the divisor. So I guess one has to find a better way here.


This topic has some insights on superfast integer division tricks, if that's something really dominating the hot path.

If you're interested in speeding ...

Windows Defender's been quite a nuisance today for apps it was completely fine with before, so definitely a bad definition update made it out...

I'm submitting my executables to MS, and I urge everyone else to do the same using the link @Fred's posted ↑4.

Big endian AArch64 is rare: iOS, Android, Windows, macOS, and most Linux distros run in LE mode on AArch64 hardware. AFAIK, BE is primarily useful for maximising performance of networking code (albeit this is serious min-maxing), but is otherwise mostly a hassle.

Given there's no big endian ...

Thanks, so I'm doing something wrong.


Is the module you're trying to invoke a method from declared prior to the caller module? E.g., in @jassing's example, mod2 may access mod1, but not the other way around due to how they're declared.

If both modules happen to be interdependent (which IMO is ...

Why the sprites are loaded in bitmap ? Is there a way to make it much more compact ?

As far as I know, all compression formats are designed for compact storage on a hard drive. A raster image is always required to display an image on the screen.


Most GPUs nowadays do support several types ...

Where is the disagreement in terms of math operations?

You're computing modulo 32 of a random memory address, so you can't really expect agreement even when using the same BE.

This isn't a typical thing you'd expect guarantees from the language for (unlike, e.g., that distinct variables have ...

Did you encounter any methods you can't call ?

From what I understand both Swift and Objective-C use objc_msgSend which is also what CocoaMessage does.


This isn't strictly accurate.

Swift code can interop with Obj-C APIs relatively simply (using objc_* / sel_* / class_* functions under-the ...

This is by (Microsoft's) design, not necessarily a PB Windows bug.

From the CreateMutexW documentation on MSDN:


If lpName matches the name of an existing event, semaphore, waitable timer, job, or file-mapping object, the function fails and the GetLastError function returns ERROR_INVALID_HANDLE ...

What if the user already had an "Untitled - Notepad" window open? Then you'll likely reposition that while opening a new blank window as well.

If you read ChatGPT's code, you'll see that it uses the newly-opened Notepad handle, thus ensuring no existing Notepad window would be affected.

I'm ...

Works great until you realise it fails if the client isn't using English Windows

That's not an issue, because it's no different to asking here how to do it and someone replying with an English answer (which happens all the time).

There's a profound difference between receiving help on a ...

It's serviceable, but there are still several problems that have to be fixed manually.



Repeat
Event = WindowEvent()
ExamineKeyboard()
; Handle input
; ... (snip)
UpdateGame()
RenderGame()

FlipBuffers()
Delay(1000 / #FPS)

Until Event = #PB_Event_CloseWindow
End



The event loop is ...

It'd probably be easiest to handle the contextmenu event on the JS side instead, that way you avoid having to write more platform-specific code. It'd also be easier to get information on the DOM node target this way.

Still, if you want to go the Cocoa route, you can respond to the WebUIDelegate 's ...

If Not SaveImage(#Image1, file$ + ".png", #PB_ImagePlugin_PNG)



You've attempted to save with the PNG encoder ( #PB_ImagePlugin_PNG ), however you've only used the decoder:



UseJPEGImageDecoder()
UsePNGImageDecoder()



If you add a UsePNGImageEncoder() call, it should function just ...
