Minecraft Username: 314. Brief Description: Sponges display a mix of their custom ECC behavior and their normal vanilla Minecraft behavior if they touch water. The custom behavior previously used to completely override vanilla behavior, but apparently this is no longer the case. Extensive Description: The white tiles of this drawing illustrate the sponge behavior. ECC uses a plugin that forces sponges to immediately clear a 9x9x9 area centered around the sponge; this used to override the vanilla sponge's (inferior) abilities that were added in 1.8. A vanilla sponge reaches further than a plugin sponge (the red tiles in the drawing), but neighboring water can flow back into this area. I decided to demonstrate it at my /home sponge. Jamie/andrew, feel free to use it if you want to test the bug. I created two equal bodies of water, then marked two locations with concrete. The sponges were then placed on top of those blocks - the left sponge touches the water, the right sponge doesn't. The sponge that didn't touch the water worked properly - a 9x9 area has been cleared. The aforementioned Wiki quote said "The absorption only propagates from water to water and won't 'jump over' non-water blocks (including air)", which means that vanilla behavior does not apply in this case. The left sponge, however, mixed both behaviors: The square's four corner blocks have been cleared; those are only accessible by the plugin sponge and not by the vanilla sponge (due to their taxicab distance of 8). The 9 water blocks at the bottom (taxicab distance 5-7) have been cleared; those are only accessible by the vanilla sponge. This area would flood again if there were any neighboring water blocks; it isn't protected from water spread like the 9x9 area. It is interesting to note that the top part (negative X direction, i.e. west) has not been affected. This might be related to the "won't absorb more than 65 blocks of water" property from the Wiki quote. When placed in a full 15x15 area of water, the sponge appears to favor the blocks to to the east over the blocks to the west for unknown reasons; I haven't tested north-south behavior yet. The best way to analyze this behavior is in one block deep water, most likely due to the aforementioned water absorption limit of 65 blocks. How many times did you recreate this bug?: Far too many times (10+). Result: An amalgamation of custom and vanilla behavior, as explained above. Sponges are not limited to the 9x9x9 area. Expected Result: The custom behavior should completely override the vanilla properties. This used to be the case, but it changed at some point, most likely during or sometime after the 1.12 upgrade. Evidence: See above. TL;DR: Sponge behavior is a mess.
@JamieSinn please check this out. @314 for sponges we use the following: https://github.com/sk89q/worldguard With the following settings: Code: simulation: sponge: enable: true radius: 5 redstone: false If you maybe want to check that out to see if you can find the issue would be great. You can also post the issue here to see if the developer can acknowledge the issue himself: http://dev.enginehub.org/youtrack/dashboard Or perhaps it's something wrong on our end. Just have so much going on it's a little hard to dedicate time to sponges specifically. But see if you guys can find something @JamieSinn @314
Currently, nothing custom impacting this, looks like a weird mix/override. Any who, not an issue that causes negative issues. Feel free to attempt fixes @314
I wanted to add this earlier today, then forgot: I managed to reproduce this error on a clean 1.12.1 server with WG 6.2.1 (84bc322), so it appears to be related to WG and not specifically ECC. Allowing me to experiment with fixes sounds like a great way to either cause more bugs or completely break the plugin...
