Godot 3.x
I’m trying to add enemies in heartbeast’s random walker generator tutorial, but I don’t know how to do it. Any suggestions? Thanks in advance
well, what part are you struggling with?
I haven’t followed said tutorial, but describing the problem more will enable more people to help you.
If you’d like, you can even link the tutorial if its on youtube or something, so other people can compare your code to theirs, if they so desire.

Here’s the complete tutorial. The problem is that he doesn’t show the code for adding the enemies in each room and I don’t know the way to do it since this is my very first Godot project.
sorry for late reply
so it looks like (From clicking on third video and seeing what he was showing the end will look like) that he indeed didnt add enemies in his.
One way to add enemies is with instance()
It looks like you’re using godot 3 atm. My gut says this tutorial may be able to help you (in ‘spawning mobs’ section) but I’m reading through to see if i can find hwat is most relevant : link : The main game scene — Godot Engine (3.5) documentation in English
you’ll for certain want to instance the enemy, as well as add it as a child to something in the scene tree (perhaps just hte scene you are in)
I’m not sure what sort of movement you want, or what sort of behavior you want, so I can’t much help more without more information (and, honestly, behavior of enemies in randomly generated scenes is not somehting i’m very familiar with)
Sorry i can’t be much more help.
The same creator HeartBeast has a great action RPG tutorial as well.
In this episode he adds an enemy.
Here’s the code I used for the generation of the level
extends Node2D
const Player = preload (“res://Player/Player.tscn”)
const Exit = preload (“res://World/ExitDoor.tscn”)
const Enemy = preload (“res://Enemies/Bat.tscn”)
var borders = Rect2(1, 1, 38, 21)
onready var tileMap = $TileMap
onready var timeLabel = $CanvasLayer/CenterContainer/TimeLabel
onready var timer = $CanvasLayer/CenterContainer/Timer
func _ready():
randomize()
generate_level()
timer.start()
func generate_level():
var walker = Walker.new(Vector2(19, 11), borders)
var map = walker.walk(200)
var player = Player.instance()
var enemy = Enemy.instance()
add_child(player)
player.position = map.front() * 32
add_child(enemy)
enemy.position = map.front() * 32
var exit = Exit.instance()
add_child(exit)
exit.position = walker.get_end_room().position * 32
exit.connect("leaving_level", self, "reload_level")
walker.queue_free()
for location in map:
tileMap.set_cellv(location, -1)
tileMap.update_bitmask_region(borders.position, borders.end)
func reload_level():
get_tree().reload_current_scene()
func time_to_live():
var time_left = timer.time_left
var minute = floor (time_left / 60)
var second = int(time_left) % 60
return [minute, second]
func _process(delta):
timeLabel.text = “TIME LEFT %02d:%02d” % time_to_live()
func _on_Timer_timeout():
get_tree().change_scene(“res://Menu/GameOver.tscn”)
This is the walker.gd file
