Important vanilla feature to implement

[rom1504]

This issue will be used to track important missing vanilla features that need implementation.
It may turn into a GitHub project when we have enough stuff

Please list here features either in text either in issue links

[rom1504]

I think #126 is a good inspiration

[wvffle]

Redstone :)

[Karang]

Redstone logic is implemented but for 1.13+ the metadata of the blocks need to be adapted.

• liquids (I have a prototype that i need to finish)
• chests
• signs (to be able to write something)
• survival inventory
• crafting, smelting

[IdanHo]

Swap item between hands key (block action packet) Done by @tumenor
Shooting arrows (also block action packet)
Hunger + food consumption
Make fast dig hack detection take items and effects into account

[Karang]

• light update (would also be useful for mineflayer because the server only send the initial light but doesn't update it on block change) => could be implemented in a prismarine-light package or directly into prismarine-chunk (as it is tightly coupled with chunk implementation)
• random block updates (grass, crops, trees, etc..)
• basic speed-hack anticheat
• advanced redstone (for now only torchs, wires and repeater are implemented)
• health/food/air in survival mode
• 1.9+ pvp

• Right clicking with a item in hand such as pick axe or sword should not place a block unless off-hand allows it

[Technisha]

Dropping an item doesn't show the item at all, also breaking blocks causes duplication (Tested with 1.12.2)

[Technisha]

Placing blocks in certain directions (using 1.15.2)
Redstone has a... Weird texture when placed. Image attached here (1.15.2)
Placing blocks places them facing away from the player (1.15.2)
Autocomplete doesn't work at all, for commands or values (1.15.2)
Mobs have no AI and just float in the air, bouncing. Image attached here (1.15.2)
When a player is opped and they rejoin (on the same server instance) it isn't saved (1.15.2)
When difficulty is changed to peaceful, hostile mobs (like creepers) don't despawn (1.15.2)

[BasToTheMax]

• Doors
• Slabs
• Stairs
• Saplings

[ghost]

[BasToTheMax]

Able to drop items (on the moment, they change to arrows)

[darksunlight]

@BasToTheMax I am currently working on that in #563

[Pandapip1]

breaking blocks causes duplication
