You can’t use silk.net with WinForms

ChristopherHollandOP•5/16/22, 8:55 PM

Okay, that explains why it wouldn't show up. Would I need to use a console project?

L

Lyris the Kitori•5/16/22, 8:55 PM

yea

C

ChristopherHollandOP•5/16/22, 9:01 PM

Still no luck. Created a C# console project. Added Silk.NET to project via nuget. Went to references and still not showing. What step am I missing?

L

Lyris the Kitori•5/16/22, 9:02 PM

wdym go to references? nuget should just import it

L

Lyris the Kitori•5/16/22, 9:05 PM

is this net core or net framework

C

ChristopherHollandOP•5/16/22, 9:08 PM

That's what I thought. In the program.cs code I added the code shown in the Tutorial 1.1 - Hello Window. Visual Studio starts throwing errors on "using" statements at the top of the code. It is .NET Framework.. The error given is: The type or namespace name 'Silk' could not be found (are you missing a using directive or an assembly reference?)

L

Lyris the Kitori•5/16/22, 9:09 PM

try .net 6 not framework

C

ChristopherHollandOP•5/16/22, 9:15 PM

That did it. Thanks for the assistance.

R

Redhacker2•5/16/22, 10:16 PM

I dont think we support framework anymore

R

Redhacker2•5/16/22, 10:17 PM

and honestly, unless you just CAN'T new code should be handled on Core not framework

R

Redhacker2•5/16/22, 10:18 PM

Framework is being kept around in support for old codebases and things that cannot move from crusty codespaces pretty much exclusively

RRedhacker2 I dont think we support framework anymore

L

Lyris the Kitori•5/16/22, 10:31 PM

we should

L

Lyris the Kitori•5/16/22, 10:31 PM

actually yeah we do

Lyris the Kitori•5/16/22, 10:31 PM

i have a framework test app

Lyris the Kitori•5/17/22, 4:16 AM

its just not something we officially support

H

Hanprogramer•5/17/22, 4:23 AM

Is this possible? I need to pass in Silk.NET's GL context to Skia's GL context

H

Hanprogramer•5/17/22, 4:24 AM

it's on android so it's a bit hacky atm

H

Hanprogramer•5/17/22, 4:25 AM

what im trying to do is create Skia's GL from SilkActivity on android

The backend on android is OpenGL ES, and apparently it doesn't have

glDrawBuffer

glDrawBuffer

glDrawBuffer

glDrawBuffer. It only exists in OpenGL. Is this true?

L

Lyris the Kitori•5/17/22, 5:40 AM

you could read the docs

L

Lyris the Kitori•5/17/22, 5:41 AM

which they state: https://www.khronos.org/registry/OpenGL-Refpages/es3.0/html/glDrawBuffers.xhtml

R

Redhacker2•5/17/22, 5:43 AM

So it's not true

H

Hanprogramer•5/17/22, 5:43 AM

Isnt it different tho? it has

Ok nevermind about that, I used another way for the GL context

but it crashes when I rotate the screen

yeah it definitely seems like its wanting to create a GL context but you are on GLES

HHanprogramer but it crashes when I rotate the screen

Lyris the Kitori•5/17/22, 8:30 AM

i get the same problem, but i assumed it was my code

i guess not

Hanprogramer•5/17/22, 8:34 AM

I wonder why

Window Size

Window Size

and

Device Size

Device Size

is different

H

Hanprogramer•5/17/22, 8:35 AM

Moreover they arent swapped number positions or anything, just random

H

Hanprogramer•5/17/22, 8:43 AM

So I think

Window Size

Window Size

doesn't rotate or change at all, which it should be changing, while the

Device Size

Device Size

does rotate

H

Hanprogramer•5/17/22, 9:15 AM

This is found right after the screen rotates

I'm curious why examples are using unsafe code. Is it necessary since I've never worked with unsafe code?

R

Redhacker2•5/17/22, 3:12 PM

Technically there are overloads that are safe

R

Redhacker2•5/17/22, 3:13 PM

However the return values might not be safe
