Searcheline

An iterative-deepening depth-first-search solver for Celeste Classic, built on Pyleste.

Usage

To define and run a search problem:

Create a class which inherits from Searcheline
Override the following methods as needed:
- init_state(self) [REQUIRED]
  - Initial state (list of game objects) to search from
  - e.g., load the room and place maddy in Searcheline's game instance (self.p8.game), return self.p8.game.objects
- allowable_actions(self, objs, player, h_movement, can_jump, can_dash)
  - Get list of available inputs for a state, with the following checks already computed:
    - h_movement: True if horizontal movement/jumps available (player x speed <= 1)
    - can_jump: True if jump available (in grace frames, next to wall, didn't jump previous frame)
    - can_dash: True if dash available (dashes > 0)
  - Default: all actions
  - Override this to restrict inputs (e.g., only up-dashes, no directional movement when player's y < 50, etc.)
- h_cost(self, objs)
  - Estimated number of steps to satisfy the goal condition
  - Default: infinity if is_rip, exit_heuristic otherwise (See below)
  - Override to change or include additional heuristics
  - is_rip(self, objs)
    - RIP conditions (situations not worth considering further)
    - Default: player dies
    - Override to change or include other rip conditions (e.g., don't consider cases where player's x > 64, etc.)
  - exit_heuristic(self, player)
    - Underestimated number of steps to exit off the top
    - Default: assumes player zips upward at a speed of 6 px/step
    - Override to specify a less conservative estimate (e.g., if exit will be off a jump, can use 3 px/step)
- is_goal(self, objs)
  - Define goal conditions
  - Default: exited the level
  - Override to change goal conditions (e.g., reach certain coordinates with a dash available)
Instantiate the class, and call instance.search(max_depth)
- Use optional argument complete=True to search up to max_depth, even if a solution has already been found

Example - 2100m

Here we'll set up a search problem to solve 2100m. Specifically, we'll work with the assumption that the player will be dashing toward the spring, like in the following GIF:

First import some useful stuff:

from Searcheline import Searcheline
import Carts.CelesteUtils as utils
import math

Create a class which inherits from Searcheline:

class Search2100(Searcheline):

In this class, override init_state(self). Because we're only considering the player dashing toward the spring, we can remove the balloons to speed things up. By default, Searcheline comes with its own PICO-8 instance with a Celeste instance loaded, self.p8. We can use CelesteUtils to load 2100m into this PICO-8 instance, suppress the balloons, and skip to after the player has spawned. The function should then return the Celeste instance's list of objects, self.p8.game.objects:

  # initial state to search from
  def init_state(self):
    utils.load_room(self.p8, 20) # load 2100m
    utils.suppress_object(self.p8, self.p8.game.balloon) # don't consider balloons
    utils.skip_player_spawn(self.p8) # skip to after player has spawned
    return self.p8.game.objects

Again, assuming the player will dash toward the spring, we only need to consider the options of holding right, jumping while holding right, as well as dashing while holding up and right. To restrict the search to these inputs, we override allowable_actions(self, objs, player, h_movement, can_jump, can_dash), where given a situation (specified by the list of objects), it should build and return a list of inputs to consider. We can make use of the can_jump and can_dash checks to only consider inputs when they're applicable:

  # get list of available inputs for a state - only consider {r, r + z, u + r + x}
  def allowable_actions(self, objs, player, h_movement, can_jump, can_dash):
    actions = [0b000010] # r
    if can_jump:
      actions.extend([0b010010]) # r + z
    if can_dash:
      actions.extend([0b100110]) # u + r + x
    return actions

By default, Searcheline's exit heuristic assumes that the player zips straight up at a speed of 6 px/step, based on an upward dash moving you at most 6 px in a single step. With prior knowledge that, from how high up the spring is, the player will be exiting off of a spring bounce, we can use a tighter heuristic of the player zipping upward at a speed of 4 px/step. Having a better estimate of the number of steps to exit the level (while strictly being an underestimate), we can greatly reduce the search space by pruning situations that provably can't exit within the current search depth. This can be done by overriding exit_heuristic(self):

  # from the input restrictions, we won't exit off of a dash- the max y displacement is 4 px off the spring
  def exit_heuristic(self, player, exit_spd_y=4):
    return math.ceil((player.y + 4) / exit_spd_y)

And that's it! We can instantiate this search problem, and use search(self, max_depth) to run the search. In this example, we'll search up to a maximum depth of 40, and set the optional complete argument to True. This optional argument makes it exhaustively search until the maximum depth, as opposed to stopping at the earliest depth a solution was found at:

# search up to depth 40 completely (i.e., don't stop after reaching the optimal depth)
s = Search2100()
solutions = s.search(40, complete=True)

Note that the frame counts are one less than the search depth (i.e., the number of inputs)- this is due to the first input being a buffered input. For readability, we can use inputs_to_english(self, inputs) to see the shortest solution in english:

# translate fastest solution to english and print
print(f"inputs: {s.inputs_to_english(solutions[0])}")

inputs: right, right, right, right, right, right, jump right, right, right, right, right, right, right, right, up-right dash, no input, no input, no input, no input, no input, no input, right, right, right, right, right, right, right, right, right, right, right, right, right

Of note, despite the assumption of dashing toward and bouncing off of the spring, the search managed to find solutions which don't use it! Recreating the depth 39 (38 frame) solution with a TAS tool, we see that it found a frame perfect corner jump to get around the spring:

Example - 100m

Here we'll set up a search problem to solve 100m, a level that's twice as long as 2100m. From its length, we'll need to rely on additional assumptions to make it manageable. Again, we start by importing some useful stuff and creating a class which inherits from Searcheline:

from Searcheline import Searcheline
import CelesteUtils as utils

class Search100(Searcheline):

We can play out some of the level ourselves with inputs that we suspect the optimal solution would start with, and then search from that point onward. Specifically, we can hand-specify and execute some initial inputs when specifying the initial state:

  # initial state to search from
  def init_state(self):
    utils.load_room(self.p8, 0) # load 100m
    utils.suppress_object(self.p8, self.p8.game.fake_wall) # don't consider berry block
    utils.skip_player_spawn(self.p8) # skip to after player has spawned
    # execute this list of initial inputs
    for a in [18, 2, 2, 2, 2, 2, 2, 2, 2, 2, 34, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]:
      self.p8.set_btn_state(a)
      self.p8.step()
    return self.p8.game.objects

This lets the search start from the 21st frame onward, specifically from this position:

As long as these inputs are in the direction of the goal, this can reduce the search depth by up to 21! Alternatively, with access to a TAS tool, one can play out the above inputs in the tool and output the player's resulting coordinates, subpixels, and speed. With this information, along with the player's grace frames and number of dashes, the player can be placed directly:

  def init_state(self):
    utils.load_room(self.p8, 0) # load 100m
    utils.suppress_object(self.p8, self.p8.game.fake_wall) # don't consider berry block
    utils.skip_player_spawn(self.p8) # skip to after player has spawned
    # place player at position {55, 79}, subpixels {0.2, 0.185},
    # speed {1.4, 0.63}, with 0 grace frames and 0 dashes
    utils.place_maddy(self.p8, 55, 79, 0.2, 0.185, 1.4, 0.63, 0, 0)
    return self.p8.game.objects

Based on prior knowledge about how human players generally climb the right side of the level, we can restrict the inputs to only consider holding right, jumping right, dashing right, dashing up, and dashing up-right:

  # get list of available inputs for a state - only consider {r, r + z, u + r + x}
  def allowable_actions(self, objs, player, h_movement, can_jump, can_dash):
    actions = [0b000010] # r
    if can_jump:
      actions.extend([0b010010]) # r + z
    if can_dash:
      actions.extend([0b100010, 0b100100, 0b100110]) # r + x, u + x, u + r + x
    return actions

We can now run our search. Here we'll specify a maximum depth of 50, but from omitting the optional complete argument, the search will stop at the depth of the first solution found:

  # search up to depth 50, but stop at the depth of the first solution found
  s = Search100()
  solutions = s.search(50)

It manages to find several 45 frame solutions, which are 66 frame solutions when acknowledging that we searched from the 21st frame onward. This search took over 10 minutes, and given a search problem's exponential growth, it likely wouldn't have been feasible to search up to depth 67 from the start, even with the heavy input restrictions. This emphasizes the care needed in setting up a feasible search problem, and how it might be better to instead run several, smaller searches from promising starts! For confirmation that we set things up right, we can combine the first solution found with the initial inputs, and play it back with a TAS tool:
