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

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

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

I love types

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

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.

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

Deleted UserOP•1/10/23, 1:39 AM

trying now

Deleted UserOP•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 UserOP•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 UserOP•1/10/23, 1:44 AM

glfwWindowHint(GLFW_MOUSE_PASSTHROUGH, GLFW_TRUE);

glfwWindowHint(GLFW_MOUSE_PASSTHROUGH, GLFW_TRUE);

Deleted UserOP•1/10/23, 1:45 AM

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

Deleted UserOP•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 UserOP•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 UserOP•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 UserOP•1/10/23, 1:57 AM

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

Aqua•1/10/23, 1:58 AM

at that point you'd have to write your own windowing system though, I don't believe silk initializes glfw until you call

window.create

window.create

, and I don't believe there's any way to give it your own window hints either

Deleted UserOP•1/10/23, 1:59 AM

Ah that's what I was afraid of

Aqua•1/10/23, 2:00 AM

aha, perfect
you can set it with ,

glfwSetWindowAttrib

glfwSetWindowAttrib

during runtime, so that's one problem solved.
now it's just about getting the glfw handle itself from the window, which I have a suspicion is something you can actually do without resorting to reflection - but I'd have to check

DDeleted User Ah that's what I was afraid of 😦

Aqua•1/10/23, 2:08 AM

hmm, seemingly not but I'm not at a machine to test it out at the moment - however you can use reflection to get the internal

Glfw

Glfw

object stored in the

GlfwWindow

GlfwWindow

and if you can get that working then I wish you the best of luck because there's no guarantees that it will be happy with the fact that you've swapped 3.3 dlls with 3.4 (for example function signature changes could cause a lot of problems)
so don't expect this to work

Deleted UserOP•1/10/23, 2:08 AM

The demo code below will allow me to setup the window borderless and transparent etc. And I'd be able to add the clickthrough if using 3.4 and setting that window hint, so that would all work. Now I'm wondering, how could I use that created window and somehow get all the goodness from Silk.NET like event handlers etc

FYI - 3.3.8 seems to contain the mouse passthrough: https://github.com/glfw/glfw

Added GLFW_MOUSE_PASSTHROUGH window hint for letting mouse input pass through the window (#1236,#1568)

does that mean I still need the 3.4 DLLs ?
