This is an error copied over from vanilla IKEMEN, but in char.ssz/char.go, yvel is assigned the value of an attack's ground hit y velocity instead of the attack's ground guard y velocity when a character is blocking. For the most part, characters don't actually suffer vertical knockback on ground block and thus wouldn't care about this, but certain custom cornerpush systems rely on yvel to be 0 for the cornerpush to be applied, so moves that knock down or launch won't apply cornerpush as intended.

The problem is that while you have hd.airguard_velocity[0] (x) and hd.airguard_velocity[1] (y) for air blocking, you only have hd.guard_velocity (x) for ground blocking, which means there's nothing to check for vertical ground guard velocity. However, were you to implement hd.guard_velocity[0] and hd.guard_velocity[1], they're supposed to default to the hit velocities when omitted from the HitDef, so the actual issue is that xvel and yvel are being written to even when the opponent isn't moving.

Sorry if that's a bit confusing.

I'm not gonna lie I'm confused.
Well reading the docs I see that guard.velocity is only a single axis. (Maybe is Elecbyte error while writing the docs)
http://www.elecbyte.com/mugendocs/sctrls.html#hitdef

I understand most of what you say except "xvel and yvel are being written to even when the opponent isn't moving"
Do you mean that guard.velocity is still applied to the char even when they are 0?

Sorry English is not my first language.

For some reason I thought guard.velocity accepted two values; in that case, simply removing the line would be the correct course of action.

Code:

if guard && int32(getter.ss.stateType)&hd.guardflag != 0 {
	ghv.hitshaketime = Max(0, hd.guard_shaketime)
	ghv.hittime = Max(0, hd.guard_hittime)
	ghv.slidetime = hd.guard_slidetime
	ghv.guarded = true
	if getter.ss.stateType == ST_A {
		ghv.ctrltime = hd.airguard_ctrltime
		ghv.xvel = hd.airguard_velocity[0] * c.localscl / getter.localscl
		ghv.yvel = hd.airguard_velocity[1] * c.localscl / getter.localscl
	} else {
		ghv.ctrltime = hd.guard_ctrltime
		ghv.xvel = hd.guard_velocity * c.localscl / getter.localscl
		ghv.yvel = hd.ground_velocity[1] * c.localscl / getter.localscl <----- Remove this line
	}
	absdamage = hd.guarddamage
	ghv.hitcount = hc

As it is now, the second value of ground.velocity (the vertical velocity) is written to yvel when the character is hit while blocking, even though the knockback isn't actually applied to the character.

Spoiler, click to toggle visibilty

That's intentional.

Code:

ghv.xvel = hd.guard_velocity * c.localscl / getter.localscl
ghv.yvel = hd.ground_velocity[1] * c.localscl / getter.localscl

But I'm not sure if MUGEN also does that.
If MUGEN does not do it I can change it but I need you to test it in MUGEN 1.1 first just to be sure.

MUGEN does not do that, which is why I brought it up; hitting a blocking opponent in MUGEN with a move that applies vertical knockback does not change the value of yvel. Some custom cornerpush systems rely on yvel being 0 (the opponent isn't in the air or falling) to apply cornerpush, so they don't work correctly in IKEMEN because of the above.

OK removed.
Thanks for the feedback.

Now that we finished this:
I discovered that you can make interactive stages using "attachedchar" inside the stage file.

Well time to decipher the reason of the Dan's crash.

So this fixes cornerpush?

edit: Just tried it out, crouch block at the end of a stage is pushing back characters who are attacking the defending character in latest ikemen, in mugen 1.1 they aren't being pushed back though. I can upload videos if needed.

That's another bug to the list.

For now I'm trying to fix more critical bugs (Crashes at the star and the fontv2 loading bug)
but once I get these out of the way I will fix the others.

Sorry, but hope that you understand.

The issue is in Github so I not forget it.
https://github.com/Windblade-GR01/Ikemen_GO/issues/3

Mind if you send the characters or the place where I can get them?
For testing in the exact same environment when the time to fix the bug comes.

Well in another news I discovered the reason why half of the fntv2 fonts crashes in Ikemen.
The palletes of these fonts doesn't load for some reason.

EDIT:
I could not get Truetype Fonts to work with lifebars but at least fntv2 fonts doesn't crashes mugen anymore.
Honestly I still don't understand anything about fonts.

Hey Gacel, I'm slowly understanding how to debug this...
currently I'm stuck in the file render.go
line 131

Code:

fragObj := compile(gl.FRAGMENT_SHADER, fragShader)

then it goes into the compile function and call on the line 110

Code:

gl.GetObjectParameterivARB(shader, gl.OBJECT_COMPILE_STATUS_ARB, &ok)

before calling this function, ok == 0
After calling, ok == 0.

Then, app panics and throw the error:

Code:

	/Volumes/data/devel/Ikemen_GO/src/main.go:22 +0x7b
main.RenderInit.func2(0xc000008b30, 0x462e502, 0x309, 0x2)

That's great!

I could not be of much help but I can link the opengl docs to the function on line 110
http://docs.gl/gl2/glGetProgram
For some reason GoGL differs in name for the one in the docs.

It seems that it fails at shader compilation.
I could not help more because I know almost nothing of openGL.

So is it recommended to use Win-Mugen SPs in this IKEMEN for now because of the font thing?

Use whatever screenpack you want but take in mind that TTF fonts doesn't work. (All the other fonts work)
It doesn't crashes mugen but these type of fonts don't display. (I fixed the crash at least)
The screenpack itself should display correctly.

You use 1.0/1.1 be prepared to change some fonts. (For now I plan to fix this)

For info about what is a TTF font:

Because the combo counter is a font someone have to fix the font support first.
I will investigate why it does not display. (Is probably a oversight somewhere)

EDIT
Does anyone know a GoLang debugger that works with CGO?
Or a way to set up a debugger in Ikemen? (To debug the go code)

I did.
Worked perfectly with visual studio code.
The only issue I had was to configure gopath, which was easy and the relative path to resources.
I end up hard coding them.
It works very well, step by step, step into and so on..

Thanks to you tips I set up the debugger!
Now fixing bugs is way easier.
And discovered the reason why the combo bar does not load.

In old dos/win-mugen the combo counter goes like this:

Code:

counter.font = 4,0,0

In Mugen 1.0/1.1 the combo code goes like this:

Code:

team1.counter.font = 5,0,1

Ikemen is programmed to load only the old winmugen combo counter.

If you modify the fight file to make it like winmugen it works!
But anyway we have to add the mugen 1.0/1.1 compatibility.

Also Dan you found the cause of the crash on your end?

But wait!! We haven't made the Suave Dude character yet!!
