Mach and Acrobike help needed

Auroran · Nov 18, 2017

So I've been trying to implement the Acro and Mach Bikes into a vanilla version of 17.2 Essentials. The script I'm using is quite an old one I found for essentials v14 (Kudos to REI) and I've performed a little cleanup to make it compatible with v17.2, and everything seems to work fine, the animations and terrain tags all work as are supposed to (though I am using placeholder graphics at the moment for the acro bike wheelies).

My issue is that bridges are completely broken, and the character is able to walk on the edge tile of a lake (though strangely not the ocean tiles). The player cannot walk further into the water, and surfing still functions normally.

I get the following error on attempting to navigate a bridge from above or underneath:

I believe the error lies in this portion of script (see spoiler tag for full script)

Code:

for i in [2, 1, 0]
      tile_id = data[x, y, i]
      next if tile_id && @terrain_tags[tile_id]==PBTerrain::Bridge &&
             [COLOR="Red"] $PokemonMap && $PokemonMap.bridge==0[/COLOR]
      if tile_id == nil
        return false
      # Make water tiles passable if player is surfing
      elsif PBTerrain.isPassableWater?(@terrain_tags[tile_id]) &&
         [COLOR="red"]$PokemonGlobal.surfing #&& self_event==$game_player[/COLOR]
        return true
      elsif @terrain_tags[tile_id]==PBTerrain::TallGrass &&
         $PokemonGlobal.bicycle && self_event==$game_player
        return false
      elsif @terrain_tags[tile_id]==PBTerrain::Bridge [COLOR="red"]&& $PokemonMap &&
            $PokemonMap.bridge>0[/COLOR]
        if @passages[tile_id] & bit != 0 ||
           @passages[tile_id] & 0x0f == 0x0f
          return false
        else
          return true
        end

I could be completely wrong, but from what I can see, from my limited understanding and the error above that the metadata doesn't define the player being on a 'bridge' so removing that condition does stop the crash from happening, however, bridges then become impassable from the top (though are passable underneath) and attempts to do the same for surfing just results in all water tiles becoming passable. Due to my lack of experience, I am unsure of what these checks are actually checking for in setting the passibility, so I could really use some help in dissecting this problem to ensure any solution keeps feature functioning as intended.

Here is my full script. I inserted it above main.

# Mach & Acro Bike Script
# By Hansiec
# Credits required
################################################################################
# * Adds the Support for Acro Bikes and Mach Bikes!
#
# * How To Use (Acro Bike):
#    - Insert Script
#    - Edit the AcroBikeFileName Setting to what your Acro Bike Graphics would be
#    - ADD THE GRAPHICS INTO THE CHARACTERS FOLDER
#    - ADD THE ITEM "ACROBIKE" (The internal name must be ACROBIKE at the very
#       least)
#
# * How To Use (Mach Bike):
#   - ADD THE ITEM "MACHBIKE" (The internal name must be MACHBIKE at the very
#       least)
#
# * How to create Acro Bike Rails:
#   - Go into the Tileset Editor (through DEBUG mode or Essentials)
#   - Find your desired Acro Bike Rails and set their Terrain Tag to 16
#   - Go into RMXP's tileset editor and set the passages (4dir) of the rails
#     to what it would normally be to pass (EG: Rails left and right need the
#     left and right passages open but the top and bottom closed)
#
#
# * How to create Acro Bike Stepping Stones:
#   - Go into the Tileset Editor (through DEBUG mode or Essentials)
#   - Find your desired Acro Bike Stepping Stones and set their Terrain Tag to 17
#   - Go into RMXP's tileset editor and set the passages of the stepping stones
#     to impassable (the script will allow you to move on them while hopping)
#
# * How to create Mach Bike Slopes:
#   - Go into the Tileset Editor (through DEBUG mode or Essentials)
#   - Find your desired Mach Bike Slopes and set their Terrain Tag to 18
#   - Go into RMXP's tileset editor and set the passages of the slope to passable
#
#
# * Updates:
#    - Fixed Where you can turn to incorrect directions on rails
#    - Fixed Where you need to do a wheelie on an Acro Bike to access rails
#    - Fixed Where there is a few frame skips between running/biking animations
#    - Fixed When you switch from the Acro Bike to a regular Bike, that the
#       regular bike has the settings of the Acro Bike
#    - Added Rail to Rail Jumping on Acro Bikes
#    - Added Mach Bike Support
