- Animating characters using pygame -





If you see closely you can see that the mickey mouse animation is made out of a lot of shapes. 

But to create something like this we need to make a very complex code. The other way around it is to use an image, other than the basic shapes, pygame also can show images.

 Using images: 

Steps to use images in my game:

> find the image you want to use 

> move it to the directory where you have created your code

 > import/load image 

To load the image we will first create an object and then use the image. load method to add the image to the object. 



here, we have created an object called an image.

 We then use the "pygame.image.load" to find the file in the directory ocean.png has to be replaced with the filename of your file.

 To place the object on a particular point of the screen we use the blit function. 




this function means that we are going to add the image onto the screen at position 0,0 mickey mouse is winking 

Using text:

We can also add text to the pygame, to add the text we need to first input the font type and font size

for this, we need to create an object that will contain the dimensions of the text and the font type


 




this object uses the "pygame.font.SysFont" class to set the font type and font-size property of the font. after this, we need to add the text we want to display, and the color of the text. 

for this, we need to create an object that contains the text we want to display and the color.

What we did here is,, that have created a new object and have called the font object, and used the render method to add the properties.




"Hello, Pygame" should be replaced by the text you want to display. “True” defines the visibility of the text and the (0,0,0) defines the color. 

If you want red color what do you do? (students should answer (255,0,0) what do you think is the color when the parameters are (0,0,0)? (Black) 

Using time:

What is happening in the above image?

the color of the image is changing over time. 

To do something similar we need to understand the use of library time. 

The time library helps us with counting seconds accurately. 

We can use the time for a lot of applications, something like the earlier image with changing color.

to use time, we first need to import the library. (it is an inbuilt library) 

import time

to change colors over time we need to stop one particular color on the screen for a few seconds. this can be achieved by using

time.sleep(1)

here we are calling the function sleep from the time library and providing it with a value of 1 which is the time in seconds. 

so if I want to stop at a particular color for 10 seconds we will use 

time.sleep(10)

Now let's understand further, we will be creating a birthday card. 

 Program Add an image to the background (update and flip are the same)











 Program to Add font to the screen.


 










 Add a background and a font 













 Program to Change background and image over time.

- Object Oriented Programming -

In OOP, we can represent an entity using a class.  A class bundles data (features/properties of entity - color, height, width) and functionality (movement, expression) together.  An instance of a class is known as an object.  Which is the only cartoon series that had predicted that Trump would be elected as the president of the USA and also predicted the coronavirus spread?   Answer: Simpsons.  Simpsons is a very popular animated show. You can build something similar with python.  But have you ever wondered, how Simpsons look the same in all the series? Only his movement looking and, expression change but his main features like color, height, and face look exactly the same all the time.  This is because we create a ‘blueprint’ of Simpsons and whenever we have to simulate him on screen we use this blueprint. This keeps a record of all the features of Simpsons and recreates it whenever we want.  This is where Object-Oriented Programming(OOP) h...

-List Slicing in Python-

 List Slicing : Slicing helps in creating a new list from an existing list.  Syntax list_name [start :end:step] Suppose you have a list of Avengers, arranged in the order of your preference.   avengers=[“Iron Man”,”Thor”,”Hulk”,”Spider Man”,”Captain America”,”Black Panther”,”Hawk Eye”,”Vision”,”Black Widow”] Later you decide to split them into a separate list like  favourite=[“Iron Man”,”Thor”,”Hulk”]                                                   less_favourite =[”Spider Man”,”Captain America”,”Black Panther”]                             least_favourite=[”Hawk Eye”,”Vision”,”Black Widow”]  Now, we have 3 lists formed from the main list. Would you want to create these lists again from the beginning? This is where list slicing helps us. Here is the code to  G...

- If structure in Python -

Decision Control Structures: The control structures help in making decisions when a program is being executed.  if Statement  : Depending on certain conditions, few statements are executed.  if-else Statement : D epending on a condition;( if true or false), statements are executed.  Elif : It’s a combination of else followed by if.  We all have made many decisions in life. (Here, decisions do not mean a big decision.)Most of our decisions depend on different conditions..isn’t it? some situations in which you had to make a decision?  ● What to order in a restaurant?  ● What to do in my free time?  ● Which movie to watch?  ● Which subject to take an elective?  ● During exams, which question to attempt first? Depending on where you are going, the dress you select to wear will also change ..isn’t it? So let's try an activity. Select the dress, according to a given condition. 1. If going to a party  2. If going out for playing  3. I...
