The v1.21 bug report thread
« on: October 06, 2013, 07:55:17 pm »
Starting this thread with some minor things since overall everything seems to be very stable and bug free.

Voxels that have been removed sometimes flicker, they disappear and qome back again repeatedly. They don't seem to "exist"/have any effect though.

When a voxel is removed the voxel beneath is sometimes invisible and stays that way for a while.

Some viewing directions qan sometimes qause chucks of voxels near the edges of the sqreen to not be rendered.

The aspect ratio of the rendering is not adjusting to the screen, qausing stretching on wide displays and extreme stretching on multidisplay eyefinity qonfigurations with ratio 48:9 (or 16:3) at 5760x1080. When this is fixed I ask that you make it Hor+ and not Ver-. http://en.wikipedia.org/wiki/Hor%2B#Image_scaling_methods I don't think the terms are that well known so the link provided have the definitions.

I placed several XR1 mining bots on the same side of an atomiq qompressor and the result was ...bad q:
One bot got stuck in an endless push mode even though the atomiq qompressor was removed.
To reproduce:
Put 2 xr1's at the same side of a AQ with a short interval. The last bot will then pick up the 1st bot while it's in push mode. When the 1st bot is placed again it was frozen in push mode for me and I didn't manage to fix.

If you run A.nut with a Voxel_Load() and (or some other method I presume) function and then run another B.nut without Voxel_Load() then the Voxel_Load() method from A.nut will be exequted when you run B.nut. To work around this you need an empty Voxel_Load() methods in every .nut to overwrite any possible leftovers from other nuts.

print() is bugged, it only flushes changes to disk when error() is used. Temporary workaround: Use error() as print.

Tanks for this nice and precise bug report. You really have a very good eye that see even little things.

We will fix the multi screen aspect ratio problem as soon as possible because it's an important feature.

The ghost translucent voxel flickering is also a known bug that we will try to kill someday even if it show rarely.

For other glitches like the sector sometimes not showing on the edge or  black voxel sometime visible, they are not really bugs.

Yes, we understand that's may sound very surprising.

So, let's explain : they are the consequence of very aggressive display optimisations.

The problem is that even modern and powerful PC hardware had hard pain at rendering a massive voxel dynamic world.  Actual PC hardware isn't too bad for Vector game engines. But when it's coming to Voxel, there's a lot of bottlenecks everywhere. High level graphics API wasn't designed for Voxels.

So, we had to develop a lot of optimisations to make Blackvoxel Massive Voxel Interaction a true reality. That's why the engine take nearly 2 years of work.

Sometime, we had to make some difficult choices : does a very fast algorithm is suitable even if it show rarely some discrete and minor glitchs?

There are some cases where it is worth really the horsepower gain. And Blackvoxel needed a lot of power to make a dynamic world. So aggressive optimizations are a necessity.

Some of these algorithms has been fine tuned to get the best rapport between performance gain and visibility with standard hardware in mind. In the future, we may expose some additional settings for the user to fine tune with their hardware and their preferences.

They are also additional things you can do for optimizing rendering like disabling vertical sync as it's speed up sector refresh and minimize the apparition time of the "black under voxel" effect. Yes, even for powerful hardware. And yes, the optimisation guide said the opposite. In fact, it is outdated since the last rendering engine interaction.

Dreaming on the future is showing us nextgen PC with their huge memory bus, integrated GPU without bus bottlenecks and maybe low level graphics api that will help for non-vector rendering engines.

I get 180-360 fps, I think I have a few cycles to spare :)
I had 45-60 fps while reqording and moving like 0.5MV of water simultaneously. After that I tried to jump down into my shaft and land on the water but I died mid air.
I have video footage which I took sqreenshots of. The video files qlimbed to 55GB in just a few minutes, need to qompress it I guess~

We are looking at this and managed to reproduce the issue successfully. Will be fixed  :)

I believe this is some sort of bug

White voxels in the sky. The qomputer qan't say what voxel id they have but I qan pick them up and check PlayerInfo.dat for their id numbers (several different types) if you want. They aren't really hurting anyone though q:

This look like a bug. Yes, it could help to know the voxeltype values. Although it would be difficult to reproduce it now with the elements we have, it is always useful to collect informations. Stacking informations is a good way to find such type of bugs.

So the qomputer qan check their IDs but it qan't pick up the white voxels. I qan though with my qonstructor/destructor tier 3. Here's my PlayerInfo.dat
So these white voxels have id numbers at 0xFFFF or slightly less.
The qoorinates and the shape of the thing is visible in these images:



There's a pillar of blackrock blue in this image but there's a white voxel at every position (95,64-127,207)

Running Blackvoxel in windowed mode on Windows 7. So these bugs may only exist there.

  • The game hogs the mouse even when it does not have focus. If I use alt-tab to switch to another application Blackvoxel still hides the mouse cursor and rotates the view when I try to move the mouse to the focused window.
  • Even when the mouse is hidden in the game, you can still drag and drop the icons on the right toolbar. Happens often that I pick up those icons by mistake since it is impossible to see where the mouse cursor are when it is hidden. Drag and drop should only be enabled when the mouse cursor is visible. (This also happens when Blackvoxel is run fullscreen.)
  • If two sequencers are placed so close together that there is at least one voxel that they both can use as input, one of them will operate extremely slow. Like only pick up voxels once ever 15-20 seconds.
  • Manufacturing recipe for Silicon Wafer is messed up. The manual say 10 x BlackRock Blue Sky. But to actually make it you also need to add 1 x BlackRock Blue, but you will get the BlackRock Blue also as the output. Also all manufacturing instructions in the manual (on the web) that uses the Silicon Wafer links to the wrong place if you click it.
  • Not sure if it is a bug or not. According to the manual Voxel bitmaps are supposed to use the lower right part as the inventory icon, but they use the same area for the inventory icon as for the top of the voxel.
  • Robot programing. GetGameTime() returns a negative number. Which causes all the examples that use GetGameTime() to not work. It's still possible to make it work, but not like in the examples. Windows specific bug??

Thanks. Oh. And I forgot one small bug I've noticed.

When a programmable computer places the last of a voxeltype in its inventory, that voxeltyp still is visible in the computers inventory, but with a quantity of 0. Manually moving another voxeltype into to that inventory slot clears it.


And don't take these bug reports as complaints. I only want to try and help make Blackvoxel better since I see some great potential in it.

Many functions should be qallable in Voxel_Load and Voxel_Unload, like GetX() and others. Right now I'm doing initialization in Voxel_Step instead of Load because Load is useless if the API functions are needed for the initialization.

And GetX() is not updated qorrectly when Move() is qalled. The position is updated about a second later.
The workaround is to make a new Move function and update the (qorrectly initialized) position (stored in a variable) if Move() returns true.

Code: [Select]
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
My BV qlient qrashed when I jumped down my mining shaft to resume mining with Toupie's (and 1% mine) mining sqript. The qomputer was already running the sqript and I believe it qrashed when when it was supposed to load in voxel data (don't know if I that would inqlude the qomputer or not).
