Missing features in Minetest to recreate Minecraft features

A side goal of the MineClone 2 project is to find any shortcomings of Minetest which make it impossible to recreate a Minecraft feature exactly. This file lists some of the missing features in Minetest which MineClone 2 would require.MineClone 2 would require.MineClone 2 would require.MineClone 2 would require.

No workaround possible

For these features, no easy Lua workaround could be found.

Lua API

Tools/wielded item

• Allow much faster liquid flowing (#2810)

• “Lock” hotbar for a brief time after using an item, making it impossible to switch item or to attach/mine/build until the delay is over (For eating with delay)

• Tool charging: Holding down the mouse and releasing it, applying a “power level” (For bow and arrows, more charge = higher arrow range) (issue 5212)

• Dual Wielding

• Eating/drinking animation (issue 2811)

Nodes

• Light level 15 for nodes (not sunlight)
• Nodes makes light level drop by 2 or or more per node (issue 5209)

Interface

• Inventory: Hold down right mouse button while holding an item stack to drop items into the slots as you move the mouse. Makes crafting MUCH faster
• Much more informative item tooltips
• Sneak+Leftclick on crafting output crafts as many items as possible and immediately puts it into the player inventory (issue 5211)

Workaround theoretically possible

For these features, a workaround (or hack ;-)) by using Lua is theoretically possible. But engine support would be clearly better, more performant, more reliable, etc.

Lua API

Nodes

• Change walking speed on block (soul sand)
• Change jumping height on block (soul sand),
• Change object movement speed through a block, but for non-liquids (for cobweb)
• Add on_walk_over event
• Set frequency in which players lose breath. 2 seconds are hardcoded in Minetest, in Minecraft it's 1 second
• Set damage frequency of damage_per_second. In Minecraft many things damage players every half-second rather than every second
• Possible to damage players directly when they are with the head inside. This allows to add Minecraft-like suffocation

Nice-to-haye

• Utility function to rotate pillar-like nodes, requiring only 3 possible orientations (X, Y, Z). Basically this is minetest.rotate_node but with less orientations; the purpur pillar would mess up if a mirrored rotation would be possible. This is already implemented in MCL2, See mcl_util for more infos
