Disabling quarry turtles

Hi,

I'm running a server with, among other mods, CC. Naturally my players have taken advantage of it to do quarrying, upon which I discovered that there's some kind of performance problem with having large chunks of empty space - probably related to mixtures of lava and water.

It's not quite as big a problem as with buildcraft quarries, but I'd still like to avoid it; hunting down this type of lag is horrible. And while you might say I should ask them not to do it, doing so is somewhat akin to herding cats.

So, is there any way to stop mining turtles from being useful for.. well, mining? Without disabling them entirely? That is, can I stop them from grabbing the block they broke, just destroying it instead?

I can't find the source code for the dig function; presumably it's an intrinsic. I can't find the java source code, either…

Not really, some servers (depending on CC version, MC version, whether its Bukkit, etc) can block certain "fake players" from destroying blocks. However this is becoming less the case, especially since the new ComputerCraft no longer has the "fake player" that works in this sense, its just there for death messages. Pretty much your only option is to disable the Mining Turtle all together, which honestly, is the better option over making the blocks it mines be destroyed. There is no point to a turtle that can dig if you get nothing from it.

The dig logic is Java-side.

That is because ComputerCraft is closed source.

Haven't specifically tested for this, but if you ask eg a woodchopping turtle to excavate, doesn't it still make it to bedrock whilst destroying all the non-wood blocks it ploughes through?

I'm also kinda curious as to what kind of "performance problems" you're experiencing. Water/lava only tend to cause lag (specifically) when moving around the world (as opposed to "flowing while sitting in the one place"); I can see them effecting frame rates, maybe, but lag…? Shouldn't be a consistant thing.

I'll have to test the woodchopping turtles.

Anyway, you're right - it doesn't cause lag in a steady state, but it gets quite spectacular if someone (say) drops a bucket of water on top of a lavafall. I have enough players that this happens occasionally.

People struggle to tell the difference between lag and frame rate drops. It was a constant problem I used to frequent, people used to scream lag, when really it was a frame rate problem, probably due to the fact that they were running 114 mods on 1GB of RAM :P/>

Not to worry, I can tell the difference.

I'm not too sure what that's meant to be proving, but I wasn't saying that you couldn't anyway, normally its non-admin people on the server.

Torrents aren't always illegal… Look at clearbits or something
