============
Dynamic Footprints - version 1.0 (2005-11-07)
============
by Wachunga
0.95 - original release
1.0 - fixed a small bug with directional footprints and
updated the compatibility list
SETUP:
1) From the database (Tileset tab), give the appropriate tiles of any
tilesets that you want to show footprints (e.g. sand in "Desert",
snow in "Snow Field") the terrain tag 1.
2) Place the footprints file in the Graphics/Tilesets folder.
To prevent an event from having any footprints (e.g. birds), include
somewhere in its name.
(If using non-RTP sprites, you may want to create customized footprints.)
FEATURES:
* customizable duration footprint fading (optional)
* direction-specific footprints (optional)
* rounded footprints paths
* overlapping footprints supported
* handles move events (jumping, speed changes, etc) and teleportation
COMPATIBILITY:
1) Cogwheel's Pixel Movement script - unfortunately, pixel movement by its
very nature isn't very compatible with footprints (short of using sprites
or pictures instead of a tileset) because a character can move part way
across a tile without footprints appearing.
2) Near Fantastica's Squad Based Movement/Action Battle System script -
make sure it is below this script
3) Near Fantastica's Updated Day Night script - again, make sure it is below
this script
4) Baskinein's Animated Sprite script - see:
http://www.rmxp.net/forums/index.php?s=&am...st&p=261921
5) Fukuyama's Caterpillar script - to only have one set of footprints
for the whole group, no modifications are necessary (just make sure his
script is above this one). To have a separate (overlapping) set of
footprints for each character, uncomment (by moving the "= end") the
following lines:
module Train_Actor
class Game_Party_Actor < Game_Character
def move_down(turn_enabled = true)
if turn_enabled
turn_down
end
if passable?(@x, @y, Input::DOWN)
turn_down
@y += 1
increase_steps
end
end
def move_left(turn_enabled = true)
if turn_enabled
turn_left
end
if passable?(@x, @y, Input::LEFT)
turn_left
@x -= 1
increase_steps
end
end
def move_right(turn_enabled = true)
if turn_enabled
turn_right
end
if passable?(@x, @y, Input::RIGHT)
turn_right
@x += 1
increase_steps
end
end
def move_up(turn_enabled = true)
if turn_enabled
turn_up
end
if passable?(@x, @y, Input::UP)
turn_up
@y -= 1
increase_steps
end
end
end
end

# Footprints for six situations (down->up, left->right, down->left,
# left->up, up->right and right->down) are required (twelve for
# directional footprints). See the provided footprints template
# (footprints_template.png) for specific details, noting
# that the right half of the template can be empty if using the default
# of non-directional footprints (i.e. leaving FP_DIRECTIONAL = false).

# footprints (e.g. footprints from player moving up are different
# from those left when player is moving down)

# the footprints won't be saved. To allow them to persist even then,
# use Near's Dynamic Maps script (slight modifications would be needed).
