- 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
