Godot - Calling a scene instance to a particular position error - game-engine

I tried to create a scene that resembles a bullet for a platformer shooter in Godot. I have created a scene with the root node being an Area2D, with a collision, and a visibility notifier. The code in that root node goes like this:
extends Area2D
export var bullet_speed = 400
var motion = Vector2()
func start():
position = Vector2()
pass
func _physics_process(delta):
motion.x = bullet_speed * delta
translate(motion)
func _on_VisibilityNotifier_screen_exited():
queue_free()
pass # Replace with function body.
Then I have a scene which has the player scene in it. In the player scene, the root node is a KinematicBody2D, A Collision Shape, and a Position2D with no name changes
The script of a player (cut short) has a physics process delta with the following commands:
const bulletlaunch = preload("res://Sprites/Gun Animation/Bullet.tscn") ##Declared the bullet scene
func _physics_process(delta):
Engine.target_fps = 60
#Playable when NOT dead
if is_dead == false:
var x_input = Input.get_action_strength("ui_right") - Input.get_action_strength("ui_left")
hud_score_display.text = String(GlobalScore.score)
score_display.text = String(GlobalScore.score)
heart_hud.value = health
if health >= 75 && health <= 100:
heart_hud.tint_progress = Color.green
if health >= 50 && health <= 74:
heart_hud.tint_progress = Color.orange
if health >= 25 && health <= 49:
heart_hud.tint_progress = Color.red
if x_input != 0:
if x_input == -1:
if playing_health_damage == false:
character.flip_h = true
character.play("Idle")
if x_input == 1:
if playing_health_damage == false:
character.flip_h = false
character.play("Idle")
motion.x += x_input * acceleration * delta
motion.x = clamp(motion.x, -max_speed, max_speed)
else:
if playing_health_damage == false:
motion.x = lerp(motion.x, 0, air_resistance)
character.play("Idle")
motion.y += gravity * delta
if is_on_floor():
if x_input == 0:
motion.x = lerp(motion.x, 0, friction)
if Input.is_action_just_pressed("ui_up"):
motion.y = -jump_force
small_jump_sound.play()
if Input.is_action_just_pressed("ui_action"): ##The place where I have the error
var bulletinstance = bulletlaunch.instance()
get_parent().add_child(bulletinstance)
bulletinstance.position = $Position2D.global_position
motion = move_and_slide(motion, Vector2.UP)
pass
However I when I press the ui_action key, I get this error
Invalid get index 'global_position' (on base: 'null instance').
Which I don't really understand..
What I've tried:
Changing the global_position to position in both of them and doing
all the combinations
Find another Position2D like replacement but I can't find anything like that
use the print(playershootpos.position) on the if ui_action statement but I seem to get the same error. Weird.
Other question:
Are there any replacements for the Position2D node?
And what is the issue?

unable to add coyote-time function

I want to add coyote time in my 2d platformer in godot but I was unable to make it work.
here is my code, I learned GDscript 2 weeks ago and i am by no mean an expert
I tried changing the code order which just made the code break many times with no results, coyote time never did work
here is the code if you find any mistake or something that can be improved, I would love to read it even if it's not about coyote time.
extends KinematicBody2D
const UP = Vector2(0,-1)
const GRAVITY = 9
const SPEED = 150
const JUMP_HEIGHT = -400
var motion = Vector2()
var coyote_time
var is_jumping = false
var was_on_floor = is_on_floor()
func _ready():
coyote_time = Timer.new()
coyote_time.one_shot = true
coyote_time.wait_time = 2.0
add_child(coyote_time)
$AnimationTree.active = true
func _physics_process(delta):
motion.y += GRAVITY
if Input.is_action_pressed("move_right"):
motion.x = SPEED
$Sprite.flip_h = false
$AnimationTree.set("parameters/state/current", 1)
elif Input.is_action_pressed("move_left"):
motion.x = -SPEED
$Sprite.flip_h = true
$AnimationTree.set("parameters/state/current", 1)
else:
motion.x = 0
$AnimationTree.set("parameters/state/current", 0)
if coyote_time.is_stopped():
motion.y += GRAVITY
if is_on_floor():
is_jumping = false
if Input.is_action_just_pressed("jump"):
is_jumping = true
motion.y = JUMP_HEIGHT
elif not is_on_floor() and was_on_floor and not is_jumping and Input.is_action_just_pressed("jump"):
coyote_time.start()
is_jumping = true
motion.y = JUMP_HEIGHT
else:
if motion.y < 0:
$AnimationTree.set("parameters/state/current", 2)
else:
$AnimationTree.set("parameters/state/current", 3)
motion = move_and_slide(motion, Vector2.UP)
pass

Colliderect function not working in Pygame

So I am making a pong game in pygame while implementing oop. My problem is the colliderect function is giving me the error " ball_hitter object has no attribute 'colliderect'". I've used the colliderect function before but it's not working for me this time.
Code:
import pygame
from pygame.locals import *
pygame.init()
screen = pygame.display.set_mode((500,500))
pygame.display.set_caption("Pong With Classes!")
#Variables
red = (255,0,0)
blue = (0,0,255)
black = (0,0,0)
clock = pygame.time.Clock()
#End of Variables
class ball_hitter:
def __init__(self,x,y,length,width,color):
self.x = x
self.y = y
self.length = length
self.width = width
self.color = color
self.left = False
self.right = False
def draw_ball_hitter(self):
screen.fill(black)
pygame.draw.rect(screen,self.color,(self.x,self.y,self.length,self.width))
#Paddle creation
paddle = ball_hitter(250,400,130,20,red)
#End of Paddle Creation
class thing_thats_being_hit:
def __init__(self,x,y,color):
self.x = x
self.y = y
self.radius = 27
self.color = color
self.speed_x = -4
self.speed_y = 4
def draw_googlyball(self):
pygame.draw.circle(screen,self.color,(self.x,self.y),self.radius)
def move(self):
self.x += self.speed_x
self.y += self.speed_y
#Ball Creation
ball = thing_thats_being_hit(200,50,blue)
#End of Ball Creation
#Paddle Collision
if paddle.colliderect(ball):
print("It Worked!")
#End Of Paddle Collision
ball.move()
while True:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
exit()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
paddle.left = True
if event.key == pygame.K_RIGHT:
paddle.right = True
if event.type == pygame.KEYUP:
if event.key == pygame.K_LEFT:
paddle.left = False
if event.type == pygame.KEYUP:
if event.key == pygame.K_RIGHT:
paddle.right = False
paddle.draw_ball_hitter()
ball.draw_googlyball()
if paddle.left == True:
paddle.x = paddle.x - 2
if paddle.right == True:
paddle.x = paddle.x + 2
if ball.x <= 0:

if ball.x >= 500:
ball.speed_x *= -1
if ball.y >= 500:
pygame.quit()
ball.move()
pygame.display.update()
clock.tick(100)
I would appreciate it if someone could give me a fixed code and explain is to me.
See How do I detect collision in pygame?. colliderect is a method of pygame.Rect. Therefore you need to create pygame.Rect objects. Also you have to do the collision test in the application loop instead of before the application loop:
while True:
# [...]
paddle_rect = pygame.Rect(paddle.x, paddle.y, paddle.width, paddle. length)
ball_rect = pygame.Rect(ball.x - ball.radius, ball.y - ball.radius,
ball.radius * 2, ball.radius * 2)
if paddle_rect.colliderect(ball_rect):
print("It Worked!")

Can this PyGame code run 60fps for >40 critters?

In my other question, some of the posters asked to see the code and suggested I make a new question. As requested, here is most of the code I'm using. I've removed the Vector class, simply because it's a lot of code. It's well-understood math that I got from someone else (https://gist.github.com/mcleonard/5351452), and cProfile didn't have much to say about any of the functions there. I've provided a link in the code, if you want to make this run-able.
This code should run, if you paste the the vector class where indicated in the code.
The problem is, once I get above 20 critters, the framerate drops rapidly from 60fps to 11fps around 50 critters.
Please excuse the spaghetti-code. Much of this is diagnostic kludging or pre-code that I intend to either remove, or turn into a behavior (instead of a hard-coded value).
This app is basically composed of 4 objects.
A Vector object provides abstracted vector operations.
A Heat Block is able to track it's own "heat" level, increase it and decrease it. It can also draw itself.
A Heat Map is composed of heat blocks which are tiled across the screen. When given coordinates, it can choose the block that those coordinates fall within.
A Critter has many features that make it able to wander around the screen, bump off of the walls and other critters, choose a new random direction, and die.
The main loop iterates through each critter in the "flock" and updates its "condition" (whether or not it's "dying"), its location, its orientation, and the heat block on which it is currently standing. The loop also iterates over each heat block to let it "cool down."
Then the main loop asks the heat map to draw itself, and then each critter in the flock to draw itself.

One thing you can already do to improve the performance is to use pygame.math.Vector2 instead of your Vector class, because it's implemented in C and therefore faster. Before I switched to pygame's vector class, I could have ~50 critters on the screen before the frame rate dropped below 60, and after the change up to ~100.
pygame.math.Vector2 doesn't have that argument method, so you need to extract it from the class and turn it into a function:
def argument(vec):
""" Returns the argument of the vector, the angle clockwise from +y."""
arg_in_rad = math.acos(Vector(0,1)*vec/vec.length())
arg_in_deg = math.degrees(arg_in_rad)
if vec.x < 0:
return 360 - arg_in_deg
else:
return arg_in_deg
And change .norm() to .length() everywhere in the program.
Also, define the font object (myfont) before the while loop. That's only a minor improvement, but every frame counts.
Another change that made a significant improvement was to streamline my collision-detection algorithm.
Formerly, I had been looping through every critter in the flock, and measuring the distance between it and every other critter in the flock. If that distance was small enough, I do something. That's n^2 checks, which is not awesome.
I'd thought about using a quadtree, but it didn't seem efficient to rebalance the whole tree every frame, because it will change every time a critter moves.
Well, I finally actually tried it, and it turns out that building a brand-new quadtree at the beginning of each frame is actually plenty fast. Once I have the tree, I pass it to the avoidance function where I just extract an intersection of any of the critters in that tree within a bounding box I care about. Then I just iterate on those neighbors to measure distances and update directions and whatnot.
Now I'm up to 150 or so critters before I start dropping frames (up from 40).
So the moral of the story is, trust evidence instead of intuition.

OOP GUI Error: main.lua:4: attempt to index local (a boolean value)... Issue with modules

Today, I was messing around with trying to make a gui class for game I'd like to start making in LOVE2D. I decided to try and use OOP to make creating new menus easier in the future. The OOP works great until I try and put it into it's own module, where it gives me the error above. I've double and triple checked my code against similar code and I can't find the problem. I've also looked it up and there are similar threads, but nothing that helps my problem. Here is the relevant code...

I'm assuming the first snippet is Game/gui and that the second part is main.lua, if this is so, You are attempting to call .new() function which is clearly absent on your Game/gui file. You need to move all of gui's functions to it's own file as well, this includes gui.new(), gui:createDropDown and gui:drawGui() last but not least, you have to return gui at the end of it's own file.
Your main file should end up somewhat like this:
local newGUI = require "Game/gui"
local menus = {
playerInv = newGUI.new()
}
function love.load()
menus.playerInv:createDropDown("right" , _, 30, 100, love.graphics.getHeight() - 60, 50, 128, 50, 255)
end
and Game/gui somewhat like this:
local gui = {} -- With all the stuff inside
function gui.new()
-- With all the stuff it had inside
end
function gui:createDropDown()
-- With all the stuff it had inside
end
function gui:drawGui()
-- With all the stuff it had inside
end
return gui
You see, you forgot to move its functions to its own file, and return gui itself. Don't forget to replace what i omitted on Game/gui!

Python twisted, reactor.callLater() not defering

The following code snippet is from a python poker server. The program works except when trying to delay the start of a tourney when a reactor.callLater is used.
The variable "wait" gets its integer from an xml file which has a setting of "60". However the delay is never implemented and the tourney always starts immediately. I am not very familiar with python or twisted just trying to hack this into working for me. One thing however from my perspective is it seems that it shouldn't work given that I can't see how or where the variable "old_state" gets its value in order for the code to properly determine the states of the server. But perhaps I am mistaken.
I hope that someone familiar with python and twisted can see what the problem might be and be willing to enlighten me on this issue.
elif old_state == TOURNAMENT_STATE_REGISTERING and new_state == TOURNAMENT_STATE_RUNNING:
self.databaseEvent(event = PacketPokerMonitorEvent.TOURNEY_START, param1 = tourney.serial)
reactor.callLater(0.01, self.tourneyBroadcastStart, tourney.serial)
# Only obey extra_wait_tourney_start if we had been registering and are now running,
# since we only want this behavior before the first deal.
wait = int(self.delays.get('extra_wait_tourney_start', 0))
if wait > 0:
reactor.callLater(wait, self.tourneyDeal, tourney)
else:
self.tourneyDeal(tourney)

I have discovered that this code has several imported files that were in another directory that I did not examine. I also made a false assumption of the purpose of this code block. I expected the function to be arbitrary and delay each tourney by n seconds but in practice it implements the delay only when a player forgets about the game and does not show up for it. These facts were made clear once I examined the proper files. Lesson learned. Look at all the imports!
