hard to tell exactly where that error comes from, I wish there were preprocessor macros in C#

Deleted UserOP•8/14/21, 8:16 AM

so I could wrap all the GL calls in a macro that, in release builds, just does the call, but in debug builds, does the call and checks/asserts errors

Deleted UserOP•8/14/21, 8:26 AM

Extension method with [Conditional("DEBUG")][Conditional("DEBUG")]

vdvman1•8/14/21, 8:26 AM

Debug.AssertDebug.Assert only does the check in debug as well

Deleted UserOP•8/14/21, 8:27 AM

Yeah, if you just want to check a single condition Debug.Assert is the way to go

Deleted UserOP•8/14/21, 8:27 AM

For more complicated stuff a method with that attribute will just be deleted when in release.

Deleted UserOP•8/14/21, 8:28 AM

(I still want to bring this to Silk.NET, but it's difficult to do without sacrificing perf)

Deleted UserOP•8/14/21, 8:32 AM

OKAY, got it working!!!

Deleted UserOP•8/14/21, 8:32 AM

you know what it was?

Deleted UserOP•8/14/21, 8:32 AM

Can't use NamedRenderbufferStorage

Deleted UserOP•8/14/21, 8:32 AM

Had to bind the renderbuffer, use RenderbufferStorage, then unbind

Deleted UserOP•8/14/21, 8:33 AM

Deleted UserOP•8/14/21, 8:33 AM

now it all works

Deleted UserOP•8/14/21, 8:33 AM

which means now I can start putting things back in place that I removed

queenvicky•8/14/21, 8:36 AM

you're getting me all exited to do another engine...

TechPizza•8/14/21, 10:27 AM

are you using glGetLastError or a debug context?

queenvicky•8/14/21, 10:30 AM

glGetErrorglGetError I think it is

Deleted UserOP•8/14/21, 10:51 AM

debug context in debug builds

Deleted UserOP•8/14/21, 10:53 AM

annnnnnyway now it seems the only thing that terribly smashes my FPS is... Circles!

Deleted UserOP•8/14/21, 10:54 AM

Circle rendering is.... complicated.

Deleted UserOP•8/14/21, 10:54 AM

Circle rendering is like the easiest thing to do what

Deleted UserOP•8/14/21, 10:55 AM

Wtf are you doing that you are having a hard time

Deleted UserOP•8/14/21, 10:55 AM

Deleted UserOP•8/14/21, 10:56 AM

okay, let me rephrase

Deleted UserOP•8/14/21, 10:56 AM

MY RENDERER's circle rendering code is...complicated

Deleted UserOP•8/14/21, 10:57 AM

because it's a port (with permission) of someone else'ss circle rendering code that was written for monogame

Deleted UserOP•8/14/21, 10:57 AM

And I do NOT understand the mental witchcraft that thing does so like

Deleted UserOP•8/14/21, 10:57 AM

I just

Deleted UserOP•8/14/21, 10:57 AM

don't touch it

Deleted UserOP•8/14/21, 10:58 AM

it crashes the engine sometimes

Deleted UserOP•8/14/21, 10:58 AM

I need better circle rendering code

Deleted UserOP•8/14/21, 11:01 AM

this is the colossal mess that is that circle code

Deleted UserOP•8/14/21, 11:01 AM

Deleted UserOP•8/14/21, 11:02 AM

I had to hack in texture support

Deleted UserOP•8/14/21, 11:02 AM

so I can render profile pictures in my game with rounding, because non-rounded profile pictures are a relic of the feckin 1400s

Deleted UserOP•8/14/21, 11:04 AM

part of the issue is maxErrormaxError defaults to an insanely low value, but

Deleted UserOP•8/14/21, 11:04 AM

the engine crashes more often the higher that value is defaulted to

Deleted UserOP•8/14/21, 11:08 AM

this is where it crashes

DDeleted User MY RENDERER's circle rendering code is...complicated

queenvicky•8/14/21, 11:28 AM

can I see your circle rendering code? Probably just beziers I believe

Deleted UserOP•8/14/21, 11:31 AM

see above

Deleted UserOP•8/14/21, 11:31 AM

I posted it

queenvicky•8/14/21, 11:31 AM

can't find it. The FillCircleFillCircle methods just call other fill circle methods.

queenvicky•8/14/21, 11:31 AM

or I don't understand it - which is more likely

Discord trims the file down on my end

try downloading it

Oh it's an unbound stack alloc!

Deleted UserOP•8/14/21, 11:32 AM

I accidentally pasted a stupidly long text rendering function in with it, my bad

Deleted UserOP•8/14/21, 11:32 AM

That's a good idea
