Hi there, thanks for opening this topic.

I was looking in vanilla source code trying to find a way to change light that block recieves to display shadow...

In short, here's my problem:

Block#setLightOpacity(0);

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

And then new map with light opacities to change it back in certain conditions...

Maybe, but there's no other way? (btw, my mod to do this already uses asm, so use it once more somewhere will not be hard... (but where exactly, i can't find...))

 

EDIT: maybe directly getLightOpacity with coords in block???

And block transformer method:

				logger.info("Patching getLightOpacity");

		}
	}

	ClassWriter writer = new ClassWriter(ClassWriter.COMPUTE_MAXS);
	classNode.accept(writer);
	return writer.toByteArray();
}

 

Any ideas, why is it happening?

Well, i got some progress, but it still isn't as i want...

From left to right: air, glass, what i'm doing.

As you can see, with glass all looks like air, but what i do is not...

What i tried to do: setting (or returning) opacity of blocks in zone to 0.

Do you have any ideas???

What are you returning for the isOpaqueCube() function in your block?

Problem is: these are not my blocks, these not even known blocks... What i'm trying ot do is with selection of zone, make all blocks within invisible... And this ligting is only problem left. I know about isOpaqueCube, and want to know if there's position sensitive version for it (like for opacity for example), Because otherwise it would be too much patching... OR there's other way around???

 

And also, i misspressed button :) , pressed thank you instead of quote... well... doesn't matter...

If you're not replacing the blocks with your own custom invisible block, how are you making those blocks invisible? Are you intercepting the rendering somehow?

Why don't you just replace the blocks with your own custom invisible blocks, and have each invisible block have what block it replaced in its NBT, so you swap them back and forth.

The thing is that if camera is inside zone, it must be rendered, if outside - not. If camera has glasses on and it's zone owner - yes... And mod needs to be server compatible (replacing blocks on client, next sync will break everything)... That's why i can't simply replace blocks with invisible blocks...

 

And actually, this is the last issue that i need to fix before releasing...

 

Oh and yes, i intercept rendring in world renderer...

Oh, just remembered another reason: if i would replace blocks, tilentities would be down so, i would need to store te data too, but also, while player is outside, everything would stop working... so yeah... Any more ideas of "Changing light value of shadow of block to be displayed..."???
