Cliff Bugfix - Avoiding the biggest cliff problem on XP

じ☆ve冰风

By default, on RPG maker XP there are two types of cliffs, tall and short ones.

Their passability and priority is different:
- On tall cliffs you CAN'T reach the edge, but you CAN walk below it.
- On short cliffs you CAN reach the edge, but you CAN'T walk below it.





This script allows to get the best of both cases on a single cliff type, so you CAN reach the edge and CAN walk below it; it basically acts one way or another based on where you got from.

I must say it's not the most intuitive script, but maybe in a future I will also release a configuration helper. For now the instructions are on the script, and if anyone has doubts about it, don't hesitate to ask them here. Sadly it also isn't the most compatible script ever, it overwrites some methods of both Game_Character and Game_Event, so have that in mind.

This script is also compatible with Extended Map Sprite Tiles & Autotiles (EMSTA). The script doesn't require it, but I recommend using both because it helps on the most complex cases.

Instructions
On the database you must define those tiles as if they were tall cliffs. Each tileset supports as many cliffs as you want.
Then you must include those tile IDs on TOP_TILES and CORNER_TILES (see instructions on the script for more details).

Spoiler: How to get the tile ID[quote]By default, the tile on the top-left has ID = 0. The script has an option to include autotiles (non-recommended), therefore tha tile would have ID = 384 instead. Then it increases by one and there are 8 in each row, so a tile with coordinates X=7, Y=3 on the tileset will be 0 + 8*3 + 7 = 31. If you're using WecTools or MENTOR they have options to easily get the tile ID as well.

Each tile type uses a distinct letter on the configuration:




There are also some constants con the configuration (see instructions on the script).

Script calls
In case you define an event on a map coordinate that has a cliff tile, it may be ambiguous to where should it appear, on top or below the cliff. By default it will appear below, but you can change that with this script call:
$game_map.events[ID].top_mode = true

You can't interact with an event that isn't on the same altitude as the player by default, even if it's in front of it by coordinate. To fix that (for example a flying event) use both the script call to send it on top and this one:
$game_map.events[ID].passable_touch = true
