Hanprogramer•1/9/23, 4:18 AM

so if i want to store a class inside a struct or just a pointer to it. would both be the same?

Hanprogramer•1/9/23, 4:19 AM

also is it dumb to store class or it's pointer in a struct?

flyke•1/9/23, 5:04 AM

In Microsoft .Net tutorials, they say - use "struct" for simple objects like "point" , and "class" for others.
There is a big article on Microsoft website, something like ".Net performance bla bla bla", they show examples in which cases structs are better.

You’re headed down a dark path of premature optimisation!

Perksey•1/9/23, 8:08 AM

When you have a class object within another class or struct, it essentially stores a pointer

Perksey•1/9/23, 8:08 AM

when the GC can’t find that pointer in any other objects or stacks, the GC will delete the object

Perksey•1/9/23, 8:09 AM

generally you shouldn’t have an object within a struct (as it balloons the struct)

can we pretend that GCHandle doesn’t exist until absolutely necessary please

Perksey•1/9/23, 8:10 AM

but yeah I use struct for Plain Old Data, anything that’s actually state should really be an object

Lyris the Kitori•1/9/23, 8:10 AM

if you think about it all GCs are handles because they all exist in some memory

yes

thanks

Lyris the Kitori•1/9/23, 8:11 AM

no problem

Lyris the Kitori•1/9/23, 8:12 AM

structs are also good for memory usage and iteration speed of an array
an AoS can be MUCH smaller

Lyris the Kitori•1/9/23, 8:13 AM

and you can iterate them faster because cache hits and whatever

Lyris the Kitori•1/9/23, 8:13 AM

Hey guys! New to Silk.NET, wanting to create a transparent window in OpenGL mode. I think the key may be in GLFW but I have no idea how to set my window transparent. I've tried to set 'options.TransparentFramebuffer = true;' but that didn't help. Is there a way to set the window transparent so I can draw a square that 'floats' on top of the desktop? e.g. for notifications and toasts etc ?

Hanprogramer•1/9/23, 1:20 PM

You could in theory get the win32 handle and then manipulate the window from there

AquaOP•1/9/23, 1:28 PM

are you clearing with

Color.Transparent

Color.Transparent

? that doesn't work (in my experience

Color.Transparent

Color.Transparent

is anything but transparent), you'll have to manually set the alpha value to 0
otherwise as long as you enable transparent framebuffer it should work fine.

Deleted User•1/9/23, 1:35 PM

Hi @grifon.petre - in my OnWindowLoad() I am doing Gl.ClearColor(1.0f, 1.0f, 1.0f, 0.5f); and then in OnWindowRender I am doing Gl.Clear(ClearBufferMask.ColorBufferBit);

LLyris the Kitori idk the specifics

Redhacker2•1/9/23, 1:36 PM

In Arrays of Objects the objects are not guaranteed to be stored Contiguously. In Arrays of Structs the structs are, meaning it's more likely the CPU has the data already sitting in cache therefore doesn't need to go and fetch it for memory

Perksey•1/9/23, 1:36 PM

uhhh

Perksey•1/9/23, 1:36 PM

where did you get that

Perksey•1/9/23, 1:37 PM

arrays are always stored contiguously

PPerksey arrays are always stored contiguously

Redhacker2•1/9/23, 1:37 PM

I'm referring to the objects not being necessarily stored contiguously

Redhacker2•1/9/23, 1:37 PM

But yeah my bad I didn't clarify well enough

Perksey•1/9/23, 1:37 PM

ah right

Perksey•1/9/23, 1:38 PM

yeah an object[]object[] is equivalent in functionality to void*[]void*[]

Redhacker2•1/9/23, 1:38 PM

And of course you can do all your typed compiler magic on top of that

AquaOP•1/9/23, 2:00 PM

yeah, using

1.0

for the color won't work, if you want a partially transparent framebuffer make sure to set r, g, and b to 0
but as perksey said by the sounds of things you want a completely transparent framebuffer so just use all 0s

AquaOP•1/9/23, 9:17 PM

after my complete and utter brainfart the other day i had a think about how to fix it in a way that worked well for the user but also meant there was no risk of the runtime moving the pointers around and i finally managed to fix it
so there are now pointer overloads (which it uses internally) and the safe overloads as well yay

So what I want to appear is the square, but not the black background, that needs to be transparent, and I should be able to click through it - it should 'float' like a toast message "You have one new viewer" or something like it.
