TSR_SideStairs
Author: TSR, The Northern Frog​

Use either map terrain tag or region Id to mark tiles on which the characters will move diagonally.
This way you can create side stairways of any height.

These tiles are meant to form diagonal stretches  that are only accesible from their extremities.
Refer to  Plugin's instructions.

1. * =========================================================================================
2. * == About this Plugin ====================================================================
3. * =========================================================================================
4. * Use map terrain tag or region Id to mark special tiles on which the
5. * characters will move diagonally. This way, you can make side stairways
6. * of any heights.
7. *
8. * When on these tiles, the characters can move normally, but can't go up
9. * or down, while right and left moves are converted into diagonal moves.
10. * This means characters can stop mid stairs, turn up and down, go back
11. * the other way around, or dash while ascending/descending the stairs.
12. *
13. * NPCs and events will also behave this way when on side stairs. You
14. * don't have to put diagonal moves in your event move route commands
15. * to make them ascend/descend the side stairs. An event that is on
16. * a side stairway tiles and have a 'move right' commmand, will move
17. * diagonally accordingly. Events that are set to move at random will
18. * also move diagonally if their movement bring them on a side stairway.
19. *
20. *
21. * How to use
22. * =========================================================================================
23. * You only need one marker (either a map region Id or a terrain tag) for
24. * all your side stairs. The marker works for stairs of both sides, that
25. * is stairs that descend from left to right, and stairs that descend from
26. * right to left.
27. *
28. * Parameters
29. * ==========
30. *
31. *    -Side Stairway ID Type
32. *        Scroll between 'tag' and 'region Id' to select your side
33. *        stairs Id type.
34. *
35. *    -Side Stairway Tag
36. *        If you choosed to use terrain tag, this parameter set the
37. *        terrain tag value that will be used to mark side stairways.
38. *
39. *    -Side Stairway Region
40. *        If you choosed to use map region Id, this parameter set the
41. *        region Id that will be used to mark side stairways.
42. *
43. *
44. * Mechanics
45. * =========
46. * Side stairway tiles are meant to form diagonal pathways of 2 or more tiles,
47. * that serves to connect 2 floors of different height on your game maps.
48. *
49. *     Example:
50. *
51. *          Bellow, 3 side stairway marked tiles (ST) are used to connect
52. *          the floor area to a 2 tiles height roof top area.      
53. *   
54. *              ---------------------
55. *              |              |     |
56. *              |  Roof top    | ST  |
57. *              |    area      |----- -----
58. *              |              |     |     |         
59. *              |              |     | ST  |
60. *              ----------------      ----- -----
61. *                                         |     |      Floor area
62. *                                         |  ST |
63. *                                          -----
64. *
65. * Side stairway tiles can only be walked in and out from both extremities
66. * of the diagonal stretch. In the previous example, this means the stairs
67. * can only be accessed from the left or right ST; you can't enter or leave
68. * the stairway from the middle ST.
69. *
70. * Side stairway tiles cannot be accessed by a vertical move. The Plugin will
71. * prevent any 'move up' or 'move down' that would bring the character either
72. * in or out of a side stairway tile.
73. *
74. * In other words, side stairway diagonal pathways can only be accessed by a
75. * lateral move in or out of their extremities tiles. But this lateral move
76. * has to be in the "direction of the stairway" after the extremity tile.
77. *
78. *     Example:
79. *        Taking the same example as previously, the stairway would only be
80. *        accessible by a 'move right' from the Roof top area into the left
81. *        ST, or a 'move left' from the floor area into the right ST.**
82. *   
83. *              ---------------------
84. *              |            <===>   |  <=//=  Can't move in/out from here
85. *              |  Roof top    |     |
86. *              |    area      |----- -----
87. *              |              |     |     |         
88. *              |              |     |     |
89. *              ----------------      ----- -----
90. *                                         |   <===>     Floor area
91. *     Can't move in/out from here  =//=>  |     |
92. *                                          -----
93. *
94. *      **In this particular case, the right ST is considered as
95. *        the 'Downstairs' tile (the lowest tile of the stairway).
96. *        The 'Downstairs' tile is the only ST that can be moved
97. *        in and out by vertical moves. See bellow.
98. *
99. *
100. * Downstairs, upstairs and midstairs
101. * ==================================
102. * Characters movement behavior will change depending of their relative
103. * position in the stairway. There's 3 disctincts positions in a side
104. * stairway:
105. *
106. *   -Downstairs
107. *       The lowest extremity tile. You can move in and out of this tile
108. *       by its upper and bottom sides, and its lateral side opposite to
109. *       the stairway. A character on this tile that go toward the lateral
110. *       side of the stairway will make a diagonal move toward the next
111. *       side stairs tile.
112. *
113. *   -Upstairs
114. *       The highest extremity tile. You can only enter and leave this tile
115. *       through its lateral side opposite to the stairway. Moving toward
116. *       the other side will make the character move diagonally to the next
117. *       side stairs tile.
118. *
119. *   -Midstairs
120. *       Any side stairway tiles in between the 2 extremity tiles. You can't
121. *       enter these tiles from outside of the stairway. A character can only
122. *       move in and out of these tiles by a diagonal movement coming from or
123. *       going to, another side stairs tiles.
124. *
125. *
126. * Bellow is a few diagrams of the stairs positions and accessibility, with
127. * different side stairs tiles arrangement.
128. *
129. * Legend:
130. *        A: Side of a tile that can be accessed
131. *           in and out by normal move.
132. *        D: represent the diagonal moves that
133. *           links the stairs tiles together.
134. *
135. *     
136. *       3 tiles right side stairway          --------------
137. *       ===========================          |            |
138. *                                            | UPSTAIRS   A
139. *                                            |            |
140. *                               ------------ D ------------
141. *                               |            |
142. *                               |  MIDSTAIRS |
143. *                               |            |
144. *                  ------ A --- D ------------
145. *                  |            |
146. *                  A DOWNSTAIRS |
147. *                  |            |
148. *                  ------ A -----
149. *
150. *       When standing on the downstairs tile, a right move will make
151. *       the character move diagonally toward the midstairs tile. On
152. *       the midstairs tile, moving right will do an up-right diagonal
153. *       move, and moving left will diagonally move the character on
154. *       the downstairs tile. The stairway can only be accessed from 3
155. *       side on the downstairs tile and the right side of the upstairs
156. *       tile.
157. *
158. *
159. *       4 tiles left side stairway      
160. *       ===========================
161. *
162. *       --------------

164. *       A  UPSTAIRS  |
165. *       |            |
166. *       ------------ D ------------
167. *                    |            |
168. *                    |  MIDSTAIRS |
169. *                    |            |
170. *                    ------------ D -----------
171. *                                 |           |

178. *                                             ------ A -----
179. *
180. *       This stairway behaves the same way as the precedent, but in the
181. *       opposite direction. There's 2 midstairs tiles, but you can put
182. *       as many as you want. Or none at all.
183. *
184. *
185. *       2 tiles right side stairway     
186. *       ===========================
187. *
188. *                               --------------
189. *                               |            |

193. *                  |            |
194. *                  A DOWNSTAIRS |
195. *                  |            |
196. *                  ------ A -----
197. *
198. *       A 2 tiles stairway is the shortest side stairways you can make.
199. *       Putting a single side stairway tile alone on the map won't do
200. *       anything (and its passability will be as normal). While the mid
201. *       stairs tiles can be ommited, side stairway always have 2 extre-
202. *       mities. But not necessarely both a downstairs AND upstairs tiles.
203. *
204. *
205. *       3 tiles ??? side stairway     
206. *       =========================

223. *                  |            |            |            |

230. *                               --------------
231. *
232. * As you can see, what's determining if a tile is either Upstairs or
233. * Downstairs, is the diagonal direction toward the next side stairs.
234. * The only thing that change, wether the extremity tile is upstairs
235. * or downstairs, is the accessibility of the tile.
236. *
237. * Downstairs have 3 sides accessibility because they're supposed to
238. * be on the lower ground. Upstairs tiles can only be accessed by one
239. * side because they're supposed to give access to an higher ground.
240. * Otherwise, one could go upstairs in one move from the lower ground.
241. *
242. * Upstairs tiles are supposed to lead to an higher ground and down-
243. * stairs tiles are supposed to lead to lower ground. But in fact,
244. * both can lead to the same level. You can even make a stairway that
245. * goes downstairs to an higher ground on the map..?
246. *
247. *
248. * Note on passability
249. * ===================
250. * When your side stairway lead to an higher ground, that is move from
251. * a floor tile to a roof top tile, or from a roof top tile to another
252. * one that is higher (somehow separated by a wall), the first roof top
253. * tile on which the upstairs tile lead must be passable. This can be
254. * easily acheived in many ways, one of them is to put an empty passable
255. * tile over the roof top tile.
256. *
257. *
258. * Straight side stairway?
259. * =======================
260. * Side stairway tiles are meant for diagonal arrangement. If you put
261. * these tiles in an horizontal straight line, all tiles will be con-
262. * sidered as 'upstairs', and it will result in creating a 'corridor'
263. * that can only be accessed from its extremities.
264. *
265. * Placing the side stairs tiles in a vertical line have a weird effect
266. * since only horizontal moves will be allowed on these tiles.
267. *
268. *
269. * Diagonal patern?
270. * ================
271. * You can make these by alterning the midstairs up and down. Is this
272. * good game making material? Nope.
273. *
274. * Is this gonna give you a good laugh? Yep!
275. *
276. *
277. *

​

Player, followers and events can move freely on the side stairways, but can't go up and down; while right and left moves are converted into diagonal moves.

Place your side stairway marker on the map if you're using region ID




Or on your tiles sheet if you're using terrain tag





​

Accessibility of the side stairway tiles changes depending on their position in the stairway. In the image bellow, the characters cannot acces the higher ground on the left directly from the floor area on the right. They can only access the upper area using the stairway.​

Side stairways can only be move in and out from their extremities. The image bellow use region Id to represent the passability of the side stairway tiles of the previous example.
*The tile with region Id 11 is a roof top tile that have to be 'passable'

Although side stairway tiles are meant to form diagonal pathways, you can also make weird paterns like in this demo:
