1. 0:02Bro, what? In Minecraft, you can attack
2. 0:05other entities from only up to three
3. 0:06blocks away, but you can actually give
4. 0:08yourself a reach of four and a half
5. 0:10blocks, increasing your reach by 50%.
6. 0:13What I'm talking about is a technique I
7. 0:14like to call triple swapping, and it's
8. 0:16actually pretty simple. All you need is
9. 0:18a spear. The tier doesn't matter. Then
10. 0:21you just need an item to start from and
11. 0:23an item to end with. Okay, it's not that
12. 0:25simple. To use this technique, you must
13. 0:27first understand how it works, starting
14. 0:29with something you probably already know
15. 0:30about, attribute swapping.
16. 0:32>> At the start of each tick, the server
17. 0:34will check for any attribute changes.
18. 0:36This is done via the tick equipment
19. 0:37update function. All we need to know is
20. 0:39that when this function runs, all
21. 0:41attribute values are recalculated.
22. 0:42Whenever you want to attack, the client
23. 0:44will run the attack function. First, it
24. 0:45lets the server know if the selected hot
25. 0:47bar slot was changed. Then, it
26. 0:49[clears throat] will tell the server you
27. 0:50are attacking an entity, which then runs
28. 0:51the logic for the attack on the server.
29. 0:53Attribute swapping occurs because the
30. 0:55server will use the attributes
31. 0:56calculated from the start of this tick,
32. 0:58but the enchantments and properties are
33. 1:00as of the selected item. A tick
34. 1:01[laughter] doesn't pass in between when
35. 1:03the selected item changes and when the
36. 1:04attack occurs. This leaves a one tick,
37. 1:06or 50 millisecond, window of time for
38. 1:08attribute swapping to occur.
39. 1:10>> While starting with a sword, switching
40. 1:12to the spear, and attacking with a mace,
41. 1:14I can actually get the sword's
42. 1:15attributes, the spear's reach, and the
43. 1:17mace's properties. But use the sword's
44. 1:18attributes at the every single tick. So,
45. 1:20how is it possible that we can switch
46. 1:22the items without attributes updating?
47. 1:24>> The client and server start their tick
48. 1:26having the sword selected. At the end of
49. 1:28the tick, the client runs the key bind
50. 1:30logic, which detects that a hot bar
51. 1:32button has [clears throat] been pressed.
52. 1:33The client then switches its selected
53. 1:35slot to the one with the spear, on the
54. 1:36client only. It does not tell the server
55. 1:39this happened yet. After this happens,
56. 1:41the player must then press the key binds
57. 1:42to switch to their mace and attack
58. 1:44[clears throat] in around 50
59. 1:46milliseconds. The next tick is started
60. 1:48on the client and server. However, the
61. 1:50client only sends the hot bar selected
62. 1:52packet after the tick starts. This means
63. 1:54that when the server starts its tick, it
64. 1:56still thinks the player has the sword
65. 1:58held because the client hasn't told it
66. 2:00that the selected item has changed yet.
67. 2:02The targeted entity is then calculated
68. 2:04on the client with the spear in their
69. 2:06hand, which means it uses the reach of
70. 2:08the spear. [laughter]
71. 2:09After that, the key binds are processed.
72. 2:11The client attacks the hopper button for
73. 2:13the mace was pressed. So, now the client
74. 2:16sees it's holding the mace. Then, the
75. 2:18attack logic starts. The critical flaw
76. 2:20allowing for spear macing is that the
77. 2:22targeted entity was calculated before
78. 2:24the key binds were handled, meaning that
79. 2:26the mace attack uses the targeted entity
80. 2:29data from when the spear was held. The
81. 2:32client then does the attack logic, which
82. 2:34notifies the server that they're holding
83. 2:35the mace and that they attacked an
84. 2:37entity. When the attack is processed on
85. 2:39the server, it sees the player is
86. 2:40holding the mace. This means we get the
87. 2:43attributes of the sword, the reach of
88. 2:44the spear, and the properties and
89. 2:46enchantments of the mace.
90. 2:48>> As you just learned, this technique is
91. 2:50entirely client-side, which means no
92. 2:51matter your ping, it's always the same.
93. 2:53On high ping, you're going to have a lot
94. 2:55of funny moments, but you still have the
95. 2:56disadvantage of being high ping player.
96. 2:58Additionally, because the technique is
97. 3:00client-side, most servers react to it
98. 3:02differently. Mine men adds a one tick
99. 3:03delay to your attack registering, so it
100. 3:05doesn't flag it straight away,
101. 3:07it was broken on PvP it's good for a
102. 3:08while, but now it's fixed. It is
103. 3:10completely normal on MCPvP, but I have
104. 3:13been banned by staff three times for
105. 3:14this. Moving on, if you've played with
106. 3:16the spear before, then you might have
107. 3:18noticed it slightly expands the hit box
108. 3:20of your enemies. Triple swapping carries
109. 3:21that over as well, often allowing hits
110. 3:23that do not look possible. There's
111. 3:25really only one downside to triple
112. 3:27swapping, that are delayed to your hits
113. 3:29because you're swapping slots. For spear
114. 3:31mace, this does not matter at all, but
115. 3:33in a SMP style game modes, you need to
116. 3:35play around it. My most important piece
117. 3:36of advice is to only triple swap when
118. 3:38you need to. Play the game like you
119. 3:40normally would, and only use the people
120. 3:42backing out or you want to gain some
121. 3:43free hits in between exchanges. One of
122. 3:45my favorite use cases is getting spring
123. 3:47hit and then pickering back using the
124. 3:49extra reach. Overall, you should try to
125. 3:51enhance your gameplay with it other than
126. 3:53base it off of it. This video just
127. 3:55explains how the technique works. It's
128. 3:57very likely that I make some follow-up
129. 3:59videos that expand on this topic
130. 4:00further. For now, that's all I have to
131. 4:01say about triple shopping. There's no
132. 4:03point in me dragging the video out any
133. 4:04longer, so see you soon.
