PureBasic Forums - English

We are not really talking about OOP. OOP with Classes, Methods, etc. was discussed 10 or 15 years ago and the result was it will not be supported by PureBasic. It is a waste of time to discuss this over and over again. I agree! PB is 100% procedural and this new transpiler is just a step into reach...

You are using #PB_Ascii as length...

(Oops, STARGATE beat me)

I have this program called "License_Generate.exe" It uses Mail and FTP and PACK libs and it gets even put in quarantaine on my system (Win Defender). So I thought it's perhaps due to those libs. (some smart-ass scan routine looking for WinApi calls concerning FTP/Mail 'n stuff...) But no! ...

I think you misunderstood me. The moment I start using StartDrawing(SpriteOutput()) or StartDrawing(ScreenOutput()), the FPS drops big time. (I am speaking about subsystem OpenGL) So, IMHO, this The returned address can be directly in video memory if the output is ScreenOutput() or SpriteOutput() an...

I hope to ASIO 2048 samples memory copy process in Bug head.

ASIO is all about latency reduction. The smaller the buffers, the better.

But if you talk about the render/mixing stage with anticipative pre-rendered buffering, then YES, AVX-512 is the way to go nowadays.

The manual says: The returned address can be directly in video memory if the output is ScreenOutput() or SpriteOutput() and allows very fast pixel manipulation. Does this also mean that 2DDrawing/VectorDrawing libs are optimised for both OpenGL/DirectX??? (can't imagine that...) In my case, p.e., wi...

Solved it!

I needed to apply a screen transformation after rotation.
What a fresh mind can do

If you swap these two lines and you paste them like this: vertex_shader + "Position = uScale*Position;"+#CRLF$ vertex_shader + "Position = uRotate*Position;"+#CRLF$ ... does it change anything? Good the Ascii(ShaderSourceCode$) : I forgot this formatting subtility. Yes, it works...

Why, oh why is the aspect ratio of the image not kept after rotate / scale? I must be misunderstanding something... If I change the screen resolution to a square (#W=#H) then it's ok, but I do not understand why since the vertexes are in world coords. #W=1200 #H=800 #GL_COLOR_BUFFER_BIT = $00004000 ...

A lexer/parser -> it looks like you must be using strings a lot?
Maybe it's as trivial as Unicode<->Ascii or something...

Hi there sq4, well I’m compiling it with gcc on Linux, and clang on macOS, using just the -g flag and whatever the default optimisations might be... I’m guessing none so probably no MMX? I have had some crashes when calling extern functions that return floats. But that was a long time ago, before P...

My experimental lib: https://www.purebasic.fr/english/viewtopic.php?f=27&t=76553 Indeed, I've tried it a couple of days ago. Nice job you did with equally distributing thread loads. Btw. what about PB v. 5.73? Yes, I still must update from 5.72. OTOH, nothing in there that I need, and like they...

A very wild guess : does the C code use MMX registers?

My suggestion however would be to use GLSL and do all effects in a shader. Its the best, fastest and most modern way to do very complex 2D (or even 3D effects). Very powerful. Indeed! ATM my "Pixys project" is hybrid . I am still using the Sprite library for textured based stuff, but I wa...
