Why does the function not return done = true if when calling another function inside where done = true is output.
For example, I submit 4 to the _apply_discrete_action function. Why does not it return done = True in the step method?

def _apply_discrete_action(self, action):
x, y = self.position
self.previous_position = self.position

    if action == 0:  # up
        self.position = (x, y - 1)
    elif action == 1:  # down
        self.position = (x, y + 1)
    elif action == 2:  # left
        self.position = (x - 1, y)
    elif action == 3:  # right
        self.position = (x + 1, y)
    elif action == 4:  # up-left
        self.position = (x - 1, y - 1)
    elif action == 5:  # up-right
        self.position = (x + 1, y - 1)
    elif action == 6:  # down-left
        self.position = (x - 1, y + 1)
    elif action == 7:  # down-right
        self.position = (x + 1, y + 1)

    # Processing: beyond map, obstacle collision
    if self.position[0] < 0 or self.position[0] >= self.map_size[0] or 
       self.position[1] < 0 or self.position[1] >= self.map_size[1] or 
       self.obstacles[self.position[1]][self.position[0]] == 1:
        self.done = True

def step(self, action):
if self.done:
raise Exception(“Episode has finished. Please reset the environment.”)

    discrete_action, continuous_action = action
    self._apply_discrete_action(discrete_action)
    self._apply_continuous_action(continuous_action)
    self.steps += 1
    time_step = self._calculate_time()
    self.total_time += time_step
    self._calculate_energy_consumption(time_step)

    reward = self._calculate_reward()
    self.done = self._check_done()

    return self._get_state(), reward, self.done

test start:
for _ in range(10):
action = (np.random.randint(8), np.random.uniform(-1, 1)) # random action
next_state, reward, done = env.step(action)
print(f”Action: {action}, Next state: {next_state}, Reward: {reward}, Done: {done}”)
if done:
break

For example, I submit 4 to the _apply_discrete_action function, why does not it return done = True in the step method?
After all, I have a check for going beyond the two-dimensional grid map, but if from the initial position [0,0] action 4 takes me beyond the map but step function does not output true. My actor definitely goes beyond the map because the next coordinate is [-1,-1]
