Hey!

Is there anything that prevent cloning the game and releasing it under their rights?

decency?

This game is pretty much same gangbeasts. What you think?

@0x00004 You may be interested in this previous Q&A

@0x00004 Unclear what "releasing it under their rights" means in that context.

ugh, why do depth-testing and blending have to interfere

Because the OVER operator is non-commutative?

i don't like it

how do you do proper transparency with depthtesting?

Depends what you mean by proper. Usually only depth writing directly conflicts with transparency, while depth testing is OK to combine.

what's the diff?

The difference between reading and writing?

i mean opengl doesn't do any depth stuff unless you glEnable DEPTH_TEST

and from then on there's no blending anymore

until you disable again that is

It should not prevent blending. Can you show us the code you're using to configure your depth and blending states?

glEnable(GL_DEPTH_TEST)
...
glEnable(GL_BLEND)
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)
...
draw
...
glDisable(GL_BLEND)
glDisable(GL_DEPTH_TEST)

what's the status of glDepthMask?

default

it's the flippin draworder again

ie. GL_TRUE? When drawing with layer transparency, you'll generally want to disable depth writes with GL_FALSE

-.-

why does it even offer depthtesting if the draworder is relevant

It's to be able to occlude transparent polygons using depth written by opaque polygons drawn earlier in your frame.

Most games will draw all the opaque geometry first, then transparency over-top.

yeah, so i can just disable depthbuffering and order my drawcalls instead

when i draw the texture with transparent parts it simply replaces the transparent bits with the clearcolour

-.-

Sounds like you're drawing with depth writing enabled, so you effectively "reserve" those pixels to not get written into by anything behind this object. (Since they'd fail the depth test against the value you wrote) So if there wasn't anything behind it when you drew it, nothing gets to be drawn there later, leaving a "hole" that looks through to your clear colour.

yeah, so there's really no diff if i use depthtesting or not, as i gotta make sure to draw transparent stuff at a different time anyways (mind it's for a ui right now, might still consider using depth-testing for worldrendering (alas with everything being sprites i could just as well reserve z-layers to use and order the drawing process by these)

Yes, drawing in ordered layers is exactly how UI is drawn.

i was still hoping i could make use of depth-testing to not having have to order stuff

You can if you're drawing opaque content. That's what the depth buffer does well. It does not provide order-independent transparency, which is a much more complicated feature if you need it. (UI generally does not need that - sorting suffices and is a lot simpler)

yeah i found out

which is why i had to complain somewhere^^

Hi! I don't find a question with reasonable depth of answers about fair xp rewards and xp tables building. I make a question and gradually the answer (gamedev.stackexchange.com/questions/186081/…). But I'm bad at english and can have a brute lack of clarity. I thank those who help improve question and answer.
