When Ice is melted the water doesn't flow

Well, this has been in the game since ice was able to melt, and the bug was known by Mojang. I can't say if it works as intended or not, Mojang has to tell us. But I think, this should stay, as it's useful and pretty much every minecraft player is using this.

I could have remembered that behaviour wrong, too. 😛

The problem with keeping bugs because some have found them useful is that they tend to make design and coding more and more difficult in future. That is, you'll get more bugs in future, and/or slower development as they try to work around bugs that are wanted to kept around.

It would be better to fix this and instead develop a water source that will not flow in any case.

That would be a fish tank 🙂

Still occurring in 1.5 pre-release

Another bug related to the BUD-Piston bug, in the sense that people would like to have it, but it's a bug. And because it's a bug, it should be fixed.

I've been thinking, couldn't this issue in particular be fixed simply by telling the code to place Block ID 8 (flowing water) instead of Block ID 9 (static water) when ice is melted by light?

@Shea: If that ice block is not surrounded by other water, does the resulting flowing water block stay around, or just dry up? Just as easy and the "correct" solution is to simply add a tiny bit delayed block update to the the melting process. (Well, I haven't tested that, but at least sounds obvious.)

@ Markku - If you look at block IDs, there are two types of water blocks - "flowing" and "static". If you use the /give command to get and place them both, you'll notice that the "flowing" water behaves like water placed from a bucket, while the "static" water acts like the issue case seen here - not flowing until it receives an update. This leaves me to conclude that melting ice replaces itself with the incorrect block.

I can understand why ice may have melted into static water in the past, since all naturally-generated bodies of water were static and any tampering with them would cause them to be forever flowing, but didn't they fix water source mechanics in 1.5?

Confirm for 14w07a

Fixed by changing this line in BlockIce.java (latest MCP):

BlockIce.java

p_149674_1_.setBlock(p_149674_2_, p_149674_3_, p_149674_4_, Blocks.water);

to this:

BlockIce.java

p_149674_1_.setBlock(p_149674_2_, p_149674_3_, p_149674_4_, Blocks.flowing_water);

This works as intended if it is explicitly refrenced.

still in 14w21b

Confirmed for 14w25b.

confirmed 14w28b

Confirmed in 14w28b. However, when a block is updated next to the water, it flows as normal.

To reproduce this effect:
1. Place a row of ice blocks
2. Place a row of fire next to that
3. After ice melts, it will not flow
4. If another ice block melts or fire block disappears next to the water, it will flow

Confirmed in 1.8.

Confirmed for 15w39c

Confirmed in 15w40b

Still present in 15w41b

Confirmed for 15w42a

Confirmed for 15w43b and 15w43c

Confirmed for 15w44a and 15w44b

Confirmed for 15w45a

Confirmed for 15w47a and 15w47c

Is this intended?

@@unknown No, otherwise it whould have been marked as Works as Intended (it was reported in 2013)

another "bug" fixed, that had no real downside, but some nice technical applications. 😞
