turbid finch
Hi everyone, I just completed the vampire survivor exercice : https://www.youtube.com/watch?v=GwCiGixlqiU&list=LL&index=1&t=6038s
I'm trying to customize it so it does the following :
- Trees spawning randomly around the player
My problem is :
- I need to control the maximum amount of trees on the screen. I'm stuck with this.
Here is my code :
extends Node2D
func _ready():
spawn_mob()
spawn_mob()
spawn_mob()
spawn_mob()
func _on_timer_timeout():
spawn_mob()
spawn_tree()
spawn_tree()
spawn_tree()
spawn_tree()
func _on_player_health_depleted():
%GameOver.visible = true
get_tree().paused = true
func spawn_mob():
var new_mob = preload("res://mob.tscn").instantiate()
%PathFollow2D.progress_ratio = randf()
new_mob.global_position = %PathFollow2D.global_position
add_child(new_mob)
func spawn_tree():
var new_tree = preload("res://pine_tree.tscn").instantiate()
#Generate random x and y coordinates around player
var random_x = randi_range(-2000 + %Player.position.x , 2000 + %Player.position.x)
var random_y = randi_range(-1100 + %Player.position.y ,1100 + %Player.position.y)
Give new_tree the random_position
var random_position = Vector2(random_x, random_y)
new_tree.position = random_position
#Adding the instance into the PineTreeGroup (Is that the way ?)
new_tree.add_to_group("PineTreeGroup")
add_child(new_tree)
#trying to count the number of PineTree instances and printing it
var PineTreeGroup = get_node("PineTreeGroup")
var count = PineTreeGroup.get_child_count()
print("Nombre d'arbre :", count)
I currently have this error :
- Attempt to call function 'get_child_count' in base 'null instance' on a null instance.
Any idea ?
