Perksey•1/9/23, 8:11 AM

w-what? This does not compute

Lyris the KitoriOP•1/9/23, 8:11 AM

yes

Perksey•1/9/23, 8:11 AM

thanks

Lyris the KitoriOP•1/9/23, 8:11 AM

no problem

Lyris the KitoriOP•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 KitoriOP•1/9/23, 8:13 AM

and you can iterate them faster because cache hits and whatever

Lyris the KitoriOP•1/9/23, 8:13 AM

idk the specifics

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

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

Aqua•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*[]

Redhacker2•1/9/23, 1:38 PM

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

I love types

Aqua•1/9/23, 2:00 PM

yeah, using

1.0

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

Aqua•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.

options.PreferredBitDepth

to (8, 8, 8, 8)` (or more if you want, this is just for testing purposes)

Deleted User•1/10/23, 1:39 AM

trying now

Deleted User•1/10/23, 1:41 AM

YESSSSS that works - it's transparent!! Now, how do I enable Click-Through?

Aqua•1/10/23, 1:42 AM

I don't believe click through is possible with glfw, potentially SDL, but you'll probably have best luck with using win32/x11/whatever directly (is click through even possible though??)
either way this is not something the silk window handles itself

Deleted User•1/10/23, 1:43 AM

Click-through is possible with glfw, lemme get the code that 'should' do it (if I could directly access the glfw component that is)

Deleted User•1/10/23, 1:44 AM

glfwWindowHint(GLFW_MOUSE_PASSTHROUGH, GLFW_TRUE);

glfwWindowHint(GLFW_MOUSE_PASSTHROUGH, GLFW_TRUE);

Deleted User•1/10/23, 1:45 AM

That would typically allow Click through. But how do I set that glfw hint?

Deleted User•1/10/23, 1:48 AM

I'm really keen on making it cross platform, so staying away from win32 / direct3d stuffs

Aqua•1/10/23, 1:49 AM

this seems like it is a new feature in 3.4, but silk uses 3.3 currently (I don't believe 3.4 has even been fully released yet)
so once 3.4 releases silk will be updated to include this too.
can't say for certain whether or not the silk windowing will be updated to feature this, but it wouldn't take much to implement it, and if you wanted to you could submit a PR to have this added too.
for now though I don't think there's much that can be done

Aqua•1/10/23, 1:51 AM

if you really wanted to you could manually replace the glfw files with ones for 3.4 and then find the integer value of

MOUSE_PASSTHROUGH

MOUSE_PASSTHROUGH

and sorta force it into the window hint, but I wouldn't recommend doing that at all

Deleted User•1/10/23, 1:51 AM

Ok that's unfortunate. So you mention SDL may be able to do it - is there an example/tutorial that draws a simple square in SDL where I can get this click-through, transparent window enabled? Just starting out with Silk.NET and really want to get this working. I'm trying to 'fail fast' based on the features I need, but I'd really like to 'succeed' as well

Aqua•1/10/23, 1:51 AM

plus you'd have to write a custom glfw window I believe

Deleted User•1/10/23, 1:52 AM

Ye that was what I was trying to do, but wasn't sure - the documentation/tutorials are few and far between. But happy to test using SDL

Aqua•1/10/23, 1:53 AM

seems like SDL does not support this

Aqua•1/10/23, 1:54 AM

I'm afraid you are pretty much out of luck on this one currently

I like this option - how do I force a value into the window hint?

Aqua•1/10/23, 1:57 AM

in theory you could do

glfw.WindowHint((WindowHintBool) IntValueOfMousePassthrough, true);

glfw.WindowHint((WindowHintBool) IntValueOfMousePassthrough, true);

Deleted User•1/10/23, 1:57 AM

I guess where I'm stuck is how do I 'inject' anything glfw into 'IWindow' object?

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