A
State
Nature of object
Q.1
A
Position
B
C
When an object change its state, Its behaviour also change. So option A is correct.
D
Movement
Which of the following library helps us to randomize the items of a list?
B
seed
pygame
Q.2
A
random
B
C
random library is use to randomize the number or list. Right option is B
D
sys
Same images
Game Feature to be added
In previous class, we learned state of bullet like ready and fired state. In this classs we will learn if bullet hit the asteroid/enemy, enemy will loss from screen.
How to disapper asteroid/enemy when bullet hit the enemy
0,0
400
600
John is playing spinner game with his friends.There are many options written on spinner such as 'Dance','Story Telling','Singing','Mimicry' and so on. Each friend will spin the spinner and have to do activity as he found on spinner.
Teacher Activity-Select a random option from given choice
import random
Activities = ['Singing','Mimicry','Story Telling','Drama','Dance']
print(random.choice(Activities))import random library
create list of activites
random.choice function return the random value from given list.
How collision can be detect in objects
x-axis
y-axis
1
2
3
4
When objects having same x or y-axis then collosion happen
Teacher Activity- Lets understand with example when two object get collosion
import pygame
a = pygame.Rect((1, 1), (2, 2))
b = pygame.Rect((0, 0), (2, 2))
c = pygame.Rect((0, 0), (1, 1))
print(a.colliderect(b))
print(a.colliderect(c))
print(b.colliderect(c)) Output is 1 because y-axis of a and b is same
Output is 0 because both axis of and is different
Output is 1 because x-axis of b and c is same
GREAT!

Teacher Activity
Step 1 - Bullet hit enemy
Same images
Creating rectangle for bullet
if enemy.y < -250 or enemy.y > 850:
evly[i] = -1*evly[i]
i+=1
if bullet.colliderect(enemy):
enemy.y=random.choice([random.randint(-250,0),random.randint(600,840)])
enemy.x=random.choice([random.randint(-250,0),random.randint(400,600)])
screen.blit(enemy_image,enemy)
if forward: Check if bullet collide the enemy
Find a random number of x and y-axis and set location of enemy.x and enemy.y on that location, which actually does not exist. So it will disappear the enemy
Same images
B
Task: Kill the enemy when a bullet hits the enemy, withouf using random.choice method.
Same images
Hint 1: Set position of enemy at a location which does not exist on game window.
Same images
i+=1
if bullet.colliderect(enemy):
#enemy.x=1000
#enemy.y=1000
10
Any number but not beteen 10,101
Q.1
Any number between 10 and 101
A
B
D
Either 10 or 101
C
random.choice( ) return a random number from a given list. So correct answer is D
1
Q
import random
num = random.choice(range(10, 101))
print(num)
What would be output of following code:-
Two rectangles are moving in a 2-D plane. A rectangle has (2,4,2,2) coordinates and B rectangle has (0,0,2,2) coordinate. If we use A.colliderect(B), What would be output?
A and B object will not collide.
A and B will Collide
Corner of Both objects will collide
Error in Syntax
A
B
C
D
Q 2
A and B are moving on different axis. A is on 2,4 coordinate and B is on 0,0 coordinate. So they will not collide. Correct answer is A
B
Hint:
1. create a list of 1 to 6 number.
2. Use random library
Additional Activity-1
Task: Create a dice game for your friends. When your friend run the game,each time they get a different number from 1 to 6.
Same images
Output :

B
Additional Activity-2
Task: Count that how many enemies are destroyed by spaceship.
Same images
Output :
Hint:
1.initialize a variable named score with 0.
2.Write your code in given line.
