Headbutt tree: Difference between revisions

Latest revision as of 08:14, 17 April 2024

Headbutt trees are special trees found in the Johto and Kanto regions that a Pokémon can use Headbutt on to encounter wild Pokémon. They are only found in the games that feature Johto: Pokémon Gold, Silver, and Crystal, and Pokémon HeartGold and SoulSilver.

Headbutting a tree in Generation II

This section is incomplete.

Reason: Confirm that formulas/algorithms apply to both Gold/Silver and Crystal (and not only to one)

In Generation II, most outdoor areas in Johto contain a number of special trees () that Pokémon can use Headbutt on. These trees are distinct from other trees that either take up two vertical paces or that have rounded tops. When a Pokémon uses Headbutt on a tree, a wild Pokémon may drop out of the tree. Depending on the time of day, the Pokémon that falls out may be asleep. Some Pokémon can only be caught by this method (e.g., Pineco, Heracross).

All headbuttable trees contain wild Pokémon, but different trees have different chances of creating an encounter after Headbutt is used. The headbuttable trees in an area also generate their encounters from different sets of Pokémon depending on whether they have moderate encounter chances or low encounter chances. For example, on Route 44, trees with moderate encounter chances may only contain Spearow or Aipom, while trees with a high encounter chance may also contain Heracross.

Encounter mechanics

The encounter rate and encounter table of each tree depends on the tree's index and the player's Trainer ID number.

The tree's index is an integer from 0 to 9, which depends on its X and Y coordinates on the map—that is, its distance from the westernmost and northernmost edges, respectively. Specifically, the tree's index is calculated using the following formula.

TreeIndex=\left\lfloor {\frac {X\cdot Y+X+Y}{5}}\right\rfloor {\bmod {1}}0

The encounter rate and tree type depends on the last digit of the player's Trainer ID.

If a tree's index is equal to that ID digit, the tree is a "high-encounter tree" and its encounter rate is 80%.
If the tree's index is one of the next four indices after that ID digit (wrapping back around to 0 after 9), the tree is a "moderate-encounter tree" and its encounter rate is 50%.
Otherwise, the tree is a "moderate-encounter tree" and its encounter rate is 10%.

Encounter rate by index and Trainer ID

The following is a table depicting the encounter rate of the tree, based on the tree index and the last digit of the player's Trainer ID. Tree indexes are displayed in rows, while Trainer ID digits are displayed in columns.

An 80% encounter rate indicates the tree is a "high-encounter tree". Otherwise it is a "moderate-encounter tree".

	0	1	2	3	4	5	6	7	8	9
0	80%	10%	10%	10%	10%	10%	50%	50%	50%	50%
1	50%	80%	10%	10%	10%	10%	10%	50%	50%	50%

6	10%	10%	50%	50%	50%	50%	80%	10%	10%	10%
7	10%	10%	10%	50%	50%	50%	50%	80%	10%	10%
8	10%	10%	10%	10%	50%	50%	50%	50%	80%	10%
9	10%	10%	10%	10%	10%	50%	50%	50%	50%	80%

Analysis

Since X and Y are interchangeable in the tree index formula, it is possible to "fix" one dimension to consider traveling along the other. Substituting "Z" for the fixed axis and "n" for the axis that will be traversed, the formula becomes:

{\begin{aligned}TreeIndex&=\left\lfloor {\frac {Z\cdot n+Z+n}{5}}\right\rfloor {\bmod {1}}0\\&=\left\lfloor {\frac {(Z+1)\cdot n+Z}{5}}\right\rfloor {\bmod {1}}0\end{aligned}}

This result shows that, if a single row or column of trees is traversed, moving to an adjacent tree increases the tree's index by ${\textstyle {\tfrac {Z+1}{5}}}$ (modulo 10), where Z is the distance of that row or column from its origin edge (north or west). This means that the closer a row or column is to the edge, the slower the indices of those trees change as the row or column is traversed.

-===Mechanics===
+===Encounter mechanics===
-Every headbuttable tree can be associated with an index from 0 to 9. Depending on the player's [[Trainer ID number|Trainer ID]], half of those indices correspond to trees with moderate encounter chances, while the other half correspond to trees with a low encounter chance.
+The encounter rate and encounter table of each tree depends on the tree's index and the player's [[Trainer ID number]].
-A tree's index depends on its X and Y coordinates in the map; that is, its distance from, respectively, the westmost and and northmost edges.
+The tree's index is an integer from 0 to 9, which depends on its X and Y coordinates on the map—that is, its distance from the westernmost and northernmost edges, respectively. Specifically, the tree's index is calculated using the following formula.
-:<code>''index'' = ( ( ''X'' * ''Y'' + ''X'' + ''Y'' ) / 5 ) [[wp:modulo operation|%]] 10</code>
+:<math>TreeIndex = \left\lfloor \frac{X \cdot Y + X + Y}{5} \right\rfloor \bmod 10</math>
-To gain some insight into this formula, it is possible to "fix" one dimension and traverse the other, since ''X'' and ''Y'' are freely interchangeable. Substituting "Z" for one axis (the fixed axis) and "n" for the other (the axis that will be traversed), the formula becomes:
+The encounter rate and tree type depends on the last digit of the player's Trainer ID.
-:<code>( ( ''Z'' * ''n'' + ''Z'' + ''n'' ) / 5 ) % 10</code>
+* If a tree's index is equal to that ID digit, the tree is a "high-encounter tree" and its encounter rate is 80%.
-which then becomes:
+* If the tree's index is one of the next four indices after that ID digit (wrapping back around to 0 after 9), the tree is a "moderate-encounter tree" and its encounter rate is 50%.
-:<code>( ( (''Z'' + 1) * ''n'' + ''Z'' ) / 5 ) % 10</code>
+* Otherwise, the tree is a "moderate-encounter tree" and its encounter rate is 10%.
-This result shows that, if a single row or column of trees is traversed (i.e., if ''n'' changes), moving from one tree to the next changes the index (before the modulo operation) by <code>(''Z'' + 1) / 5</code>, where ''Z'' is the distance of that row or column from its origin edge (north or west). In short, the closer a row or column is to the edge (the smaller ''Z'' is), the slower the indices of those trees will change as the row or column is traversed.
+====Encounter rate by index and Trainer ID====
+The following is a table depicting the encounter rate of the tree, based on the tree index and the last digit of the player's Trainer ID. Tree indexes are displayed in rows, while Trainer ID digits are displayed in columns.
-The encounter chances associated with a tree of a given index are determined by a "pivot" index determined by the player's Trainer ID (specifically, the rightmost digit of the player's Trainer ID).
+An 80% encounter rate indicates the tree is a "high-encounter tree". Otherwise it is a "moderate-encounter tree".

+====Analysis====
+Since X and Y are interchangeable in the tree index formula, it is possible to "fix" one dimension to consider traveling along the other. Substituting "Z" for the fixed axis and "n" for the axis that will be traversed, the formula becomes:
+:<math>
+\begin{align}
+TreeIndex &= \left\lfloor \frac{Z \cdot n + Z + n}{5} \right\rfloor \bmod 10 \\
+&= \left\lfloor \frac{(Z + 1) \cdot n + Z}{5} \right\rfloor \bmod 10
+\end{align}
+</math>
-If a tree's index matches the pivot index, its encounter chances are 80%; the next four tree indices (effectively, <code>( ''pivot'' + ''n'' ) % 10</code>, where ''n'' = 1...4) have encounter chances of 50%; and the remaining indices have encounter chances of 10%. The 80% and 50% indices make up the "moderate" encounter chances referred to above, and share a common set of Pokémon from which encounters are created, while the 10% indices draw from a different set of Pokémon for encounters.
+This result shows that, if a single row or column of trees is traversed, moving to an adjacent tree increases the tree's index by <math display="inline">\tfrac{Z + 1}{5}</math> (modulo 10), where ''Z'' is the distance of that row or column from its origin edge (north or west). This means that the closer a row or column is to the edge, the slower the indices of those trees change as the row or column is traversed.

 ==Generation IV==
 [[File:Headbutt IV OW.png|thumb|{{m|Headbutt}}ing a tree in [[Generation IV]]]]
-In {{game|HeartGold and SoulSilver|s}}, Pokémon are not grouped by terrain, but now appear in specific locations. Unlike [[Generation II]], not all trees will guarantee an encounter with a wild Pokémon. However, if a tree does cause a wild Pokémon to appear, there is a high chance of encountering a Pokémon again next time, even if [[Repel]] is being used. Likewise, if no Pokémon appears when a tree is Headbutted, no Pokémon will ever appear for that tree.
+In {{game|HeartGold and SoulSilver|s}}, Pokémon are now pre-defined for each eligible location. Due to this, the levels of Pokémon vary between locations, and the player can now find Pokémon in Kanto beyond {{rt|26|Kanto|Routes 26}} and {{rtn|27|Kanto}}. The player can Headbutt trees while {{m|Surf}}ing, and in fact certain encounter trees are otherwise unreachable.
+Each location has a pre-defined list of trees that can contain encounters. Each of these trees can have encounters from one of two encounter tables, or have no encounters at all. Which group the tree falls into depends on the player's [[Trainer ID number|Trainer ID]] and [[secret ID]]. Unlike in [[Generation II]], a Headbutt tree that contains encounters will always yield one when headbutted; [[Repel]] cannot prevent Pokémon from appearing when headbutting a tree.
+In addition to the standard two encounter tables, some locations have a third encounter table assigned to certain trees. These locations are [[Pewter City]], [[Cherrygrove City]], {{rt|25|Kanto|Routes 25}}, {{rtn|38|Johto}}, and {{rtn|47|Johto}}, and [[National Park]]; the ones on Route 38 and in Cherrygrove City and National Park require scaling a [[rocky wall]] to access.
+The amount of designated trees with Pokémon can range from as few as 2, to as many as 44 or 45 in [[Ilex Forest]].
+===Encounter mechanics===
+The encounter type of each tree is determined by the player's full ID number and the number of designated trees in the area.
-Also, the population of Pokémon differs from tree to tree, as illustrated below.
+The player's full ID number is a 4-byte number, composed by concatenating their [[Secret ID]] (as the upper byte) with their [[Trainer ID number|Trainer ID]] (as the lower byte).
-{| style="margin:auto; {{roundy|20px}} border: 2px solid #{{locationcolor/dark|land}}; background: #{{locationcolor/light|land}};" width="50%"
+The number of designated trees is the number of trees (except Group C trees) that can possibly have headbutt encounters. The following table details how many designated trees are in each location.

+To determine which encounters are used, the value <math>X = ID_{full} \mod 10</math> is derived from the player's full ID. This value (''X''), the number of designated trees (''n''), and the ID of the tree within the location's headbutt array (''Tree<sub>ID</sub>'') are used to determine which encounter table is used.
+* If ''n'' is 1 (unused): The tree will have group A encounters if ''X'' is even, and group B if ''X'' is odd.
+* If ''n'' is 2, 3, or 4: <math>Encounter_{ID} = Tree_{ID} + (X \times n)</math>, then lookup the tree type from the table below
+* If ''n'' 5 or more: <math>Encounter_{ID} = (Tree_{ID} \mod 5) + (X \times 5)</math>, then lookup the tree type from the table below
+In the following table, columns refer to the number of designated trees in the area, while rows refer to ''Encounter<sub>ID</sub>''. Cases with no encounters are marked with –.

-For example, a tree in [[Pewter City]] may house {{p|Hoothoot}}, {{p|Pineco}} and {{p|Wurmple}}, while another in the same locality may house only Hoothoot and Wurmple. The level ranges may also differ for the same Pokémon. As such, not all Pokémon may be found in one tree within a specific location; the (Pewter City) table only reflects the lowest and highest possible level of all Pokémon found in the entire location.
+Due to the way the trees are assigned encounters, certain IDs have one less tree with encounters. For example, locations with 4 potential encounter trees have one tree with no encounters ''unless'' the ID combination results in X of 4 and 9. Similarly, in Ilex Forest, if an ID combination results in 0 or 5, there will be 12 trees without encounters instead of 11.
+====Example====
+For Trainer ID of 19410 (0x4BD2) and secret ID of 21243 (0x52FB):
+:<math>
+\begin{align}
+ID_{full} &= ID_{secret} || ID_{trainer} \\
+ID_{full} &= 52FB4BD2_{16} \\
+ID_{full} &= 1392200658_{10}
+\end{align}
+</math>
+:<math>
+\begin{align}
+X & = ID_{full} \mod 10 \\
+X & = 1392200658 \mod 10 \\
+X & = 8
+\end{align}
+</math>
-This also explains why some Pokémon can only be found in a ''specific tree'' within that location (e.g. {{p|Starly}} in Pewter City or {{p|Taillow}} in [[Cherrygrove City]]). These trees are usually hidden, or only accessible via an [[HM]] like {{m|Surf}} or {{m|Rock Climb}}.
+With X of 8, ''Encounter<sub>ID</sub>'' for first tree in the location is 16 for areas with 2 potential encounter trees, 24 for areas with 3, 32 for areas with 4, and 40 for areas with more than 4. In the first case, the tree has encounter group A; in all other cases it has encounter group B.
