How to get the position of the target.

[Yutaro Kikuchi]

Hello

I am trying to get the position of target in the basical model(https://github.com/mwydmuch/ViZDoom/blob/master/examples/python/basic.py).

I fixed Action Code Script in WAD and make the python script accesible position of the target through GameVariable.USER1~3.

However, the value returned from GameVariable.USER1~3 is 0.0 always.

As a trial, I runned the shaping.py (https://github.com/YutaroKikuchi/VizDoom/blob/develop/examples/python/shaping.py). Curiously it worked correctly.

What is the missing in this implementation?

Here is ASC

#include "zcommon.acs"

int target_id = 10;

global int 0:reward;

global int 1:target_x;

global int 2:target_y;

global int 3:target_z;

global int 4:test;

script 1 OPEN

{

    test = 100;

    SpawnTarget();

    reward = 0;

print(s:"Hello");

}

int c =0;

script 2 ENTER

{

    test = 100;

    TakeInventory("Fist",1);

    ACS_Execute(3, 1, 0, 0, 0);

}

script 3 (void)

{

    int bullets = CheckInventory("Clip");

    while(true)

    {        

        int t_bullets = CheckInventory("Clip");

        if(t_bullets < bullets)

        {

            reward = reward - 5.0;

        }

        bullets = t_bullets;

    

        delay(1);

    }

}

script 4 (void)

{

    reward = reward + 106.0;

    Exit_Normal(0);

}

function void SpawnTarget(void)

{

    int y = Random(-161.0,224.0);

    target_x = 100;

    target_y = y;

    target_z = 100;

    Spawn("Cacodemon", 0.0, y,0.0,target_id,128);

    //disables movement

    SetActorProperty(target_id, APROP_Speed, 0);

    //makes it die on one hit

    SetActorProperty(target_id, APROP_Health, 1);

    //makes it ignore the player and attack actor with tid 100

    Thing_Hate (target_id, 100, 6);

    SetThingSpecial(target_id, ACS_ExecuteAlways, 4);

   

}

And then, Here is the python script named "test_game_variables.py" based basic.py

#!/usr/bin/env python

from __future__ import print_function
from vizdoom import *

from random import choice
from time import sleep

def initialize_game():
 game = DoomGame()
 game.load_config("./config/basic.cfg")
 game.set_doom_map("map01")
 game.init()

 return game

actions = [[True, False, False], [False, True, False], [False, False, True]]

game = initialize_game()


episodes = 1

# Sets time that will pause the engine after each action (in seconds)
# Without this everything would go too fast for you to keep track of what's happening.
sleep_time = 1.0 / DEFAULT_TICRATE # = 0.028

for i in range(episodes):
 print("Episode #" + str(i + 1))

 # Starts a new episode. It is not needed right after init() but it doesn't cost much. At least the loop is nicer.
 game.new_episode()

 while not game.is_episode_finished():

  # Gets the state
  state = game.get_state()

  # Get Position from GameVariable
  pos_x = game.get_game_variable(GameVariable.USER1)
  pos_y = game.get_game_variable(GameVariable.USER2)
  pos_z = game.get_game_variable(GameVariable.USER3)
  test = game.get_game_variable(GameVariable.USER4)

  pos_x = doom_fixed_to_double(pos_x)
  pos_y = doom_fixed_to_double(pos_y)
  pos_z = doom_fixed_to_double(pos_z)

  # Which consists of:
  n = state.number
  vars = state.game_variables
  screen_buf = state.screen_buffer
  depth_buf = state.depth_buffer
  labels_buf = state.labels_buffer
  automap_buf = state.automap_buffer
  labels = state.labels

  # Makes a random action and get remember reward.
  r = game.make_action(choice(actions))

  # Prints state's game variables and reward.

  print("State #" + str(n))
  print("test:",test)
  print("Game variables:", vars)
  print("X{0}, Y:{0}, X:{0}".format(pos_x, pos_y, pos_z))
  print(type(pos_x))
  print("Reward:", r)
  print("=====================")

  if sleep_time > 0:
  sleep(sleep_time)

  # Check how the episode went.
  print("Episode finished.")
  print("Total reward:", game.get_total_reward())
  print("************************")

# It will be done automatically anyway but sometimes you need to do it in the middle of the program...
game.close()

Does anyone have idea?

Thanks

I solved it by myself.
Reason is that I forgot compile ACS previously.

I use SLADE3 as editor, and configured the directory of Action Code Compiler in SLADE3.

Finaly I compiled ACS by Right-Click.

Thanks
