Do you have the ability to make chunkloaders? If so, try placing one down in the area, and let me know if the issue continues. If not, it's likely a render upon load issue, but if so, I dunno.

[Furest_]

I've already tried and in both cases it crashes...

When I teleport out of render distance and walk to the area, it's just fine but I just can't "suddenly" teleport near them, it just crasher. But when I log on the server again, I just spawn where I am supposed to without crashing again.
It seems to be a problem with the chunk unloading maybe, or a problem with the ressources when loading...

fwiw, I've had the same symptoms using LanteaCraft stargates and CC 1.63

[Furest_]

Maybe but please, read the previous topics. The crashes happened without any other mod!

what Dog is attempting to point out is that this is not a problem found exclusively in this mod, but in fact it is present in many mods, indicating that perhaps it is not a problem with the mod, but in fact something else, like Minecraft, OpenGL, or your hardware drivers. This issue is most certainly related to this one.

[Furest_]

I have a doubt wether the problem is hardware related or not.
I invite Dog to try again and try then without the other mod. Then paste the crash report.
Then, I have to say that all the players on my server crash at this point! If I place down one monitor in the crucial area, they will crash. And I think everybody will crash.
My openGL is most often disabled because it doesn't increase anything for us. So it's maybe not related to this.
Then, With GeForce experience, our drivers are always up to date and the different versions we've had yet haven't changed anything.

It would be great if we could have your crash report Dog

Here's one I just generated in SSP (I don't have the server for this install any more). This is with the latest GeForce drivers and Advanced OpenGL disabled. Distance makes a difference - if I step through a couple of nearby stargates and back this doesn't happen. This is a modded client, not just CC and LanteaCraft.

And if you try to do this but with only cc, what happen?

You expect him to step through a LanteaCraft Stargate with only CC installed... hmmm...

[Furest_]

Why? The /tp command still exists.
And so, lanteacraft is a teleporting mod. So it does not influence the crashes.
Still a computercraft related issue thus.

[Cranium]

It's NOT only a computercraft related issue. This occurs with many mods that do their own rendering via openGL. Such as Lanteacraft.

Sorry to necro, but I thought this would be useful -

http://pastebin.com/iiyAgN0v

I crash when breaking monitors faster than about 1/second (no teleporting necessary). The block goes but the front face stays for a second, then the whole screen goes a muted blue. Then I'm back to the launcher.

[C42Ralf]

Hi!

First of all: Computercraft is a really great mod.
(I love to program my turtles).

About the bug: I got exactly the same error, if I teleport.
I am using Forge 1.7.10, IC2, Optifine and the actual version of Computercraft. Any chance for a bug fix?

Thanks in advance!
Ralf

[zortag]

i have the same issue with computercraft 1.65

[punkdown]

I run a small private server with CC 1.65 and we all experience this crash quite often.

[valithor]

I am honestly suprised this topic is still open, and that people are still posting on it. This is a forge rendering bug. It happens with a lot of mods while rendering certain blocks. In CC's case it is monitors, and sometimes computers. There are certain circumstances that when met cause a crash. One way to prevent it is to not teleport near blocks that can cause the crash. Dying can also cause a similar crash.

[Plawerth]

Sigh, I just built a beautiful spawn on 1.7.10 / CC 1.6.5 with a bunch of CC monitors all over the place with info for players.

But I'm expecting a bunch of people on this server, so we have to keep the chunkloading low, so the player view distance has been changed from 10 to 3.

Now suddenly I'm constantly crashing moving around by the spawn as chunks load and unload, or people teleport away from the spawn.

It looks to me like it involves chunks loading and unloading while the monitor is running, probably a race condition between "chunk loading/loaded/unloaded" and "try to render stuff on a monitor that isn't there yet/anymore".

I just watched it. Backed away from a monitor so I could see it, it got to the edge of the 3 chunk view distance and chunk unloaded, monitor disappeared, client lag .... 1 second pause.... and the usual crash occurs:

java.lang.NullPointerException: Rendering Block Entity
at dan200.computercraft.shared.peripheral.monitor.TileMonitor.getTerminal(TileMonitor.java:354)
at dan200.computercraft.client.render.TileEntityMonitorRenderer.renderTileEntityMonitorAt(TileEntityMonitorRenderer.java:45)
at dan200.computercraft.client.render.TileEntityMonitorRenderer.func_147500_a(TileEntityMonitorRenderer.java:194)
at net.minecraft.client.renderer.tileentity.TileEntityRendererDispatcher.func_147549_a(SourceFile:100)

Is the java code for this project public anywhere? I'm not finding a github with the CC java source, though um, no problems using the http://jd.benow.ca/ Java Decompiler..

dan200.computercraft / shared / peripheral / monitor / tilemonitor

  public ITerminal getTerminal()
  {
	TileMonitor origin = getOrigin();		   (line 353)
	return origin.getLocalTerminal();			(line 354)
  }

Looks like when it redraws the monitor, the code is trying to find the terminal that updates that monitor. Except for whatever reason the origin (3D coordinates of a block in the world) of the terminal is null (doesn't exist/anymore), so there's no terminal found to update the monitor to render it in OpenGL.

How about if origin.getLocalTerminal() is null, don't try to render the monitor (anymore)?

[direTry20]

The Same thing is happening to me. But even when i'm just going around my base i crash.

To test if it was the monitors i created waypoints on the edges of my monitor, as soon as they are about to come in to view i crash.

The monitors are ~70ish blocks away with two walls in between me and the monitors.

I have a chicken chunks chunk loader roughly in the middle (by coincidence) set to 7 chunks

i am running the DireWolf20 1.0.4 pack from FTB and have Fastcraft installed and active


Thanks in advance
