Drawing Objects and Shapes in PyGame

You can easily draw basic shapes in pygame using the draw method of pygame. 

Drawing Rectangle shape: 

To draw a rectangle in your pygame project you can use draw.rect() function.

Syntax: pygame.draw.rect(surface, color, rect, width)

Parameters:

• surface :- Here we can pass the surface on which we want to draw our rectangle. In the above example, we created a surface object named ‘window’.
• color :- Here we can pass the color for our rectangle. We are using blue color in our example.
• rect :- Here we can pass the rectangle, position, and dimensions.
• width :- Here we can pass the line thickness. we can also create a solid rectangle by changing the value of this width parameter. So let’s look at that.

First, import the required module and initialize pygame. Now, Create the surface object of a specific dimension using the display.set_mode() method of pygame. Fill the background of the surface object with white color using the fill() function of pygame. Create a rectangle using the draw.rect() method of pygame. Update the Surface object.

Example 1: Drawing outlined rectangle using pygame.

Output :

We can create a solid rectangle by setting the width parameter equal to 0 and the rest of the approach remains the same.

Example 2: Drawing a solid rectangle.

Output :

Drawing Circle Shape:

To draw a circle in your pygame project you can use draw.circle() function. The entire approach is the same as above only the function and parameters are changed accordingly.

Syntax : pygame.draw.circle(surface, color, center, radius, width)

Parameters :

• surface :- Here we can pass the surface on which we want to draw our circle. In the above example, we created a surface object named ‘window’.
• color :- Here we can pass the color for our circle. We are using green color in our example.
• center :- Here we can pass the ( x, y ) coordinates for the center of the circle.
• radius :- Here we can pass the radius of our circle.
• width :- Here we can pass the line thickness. we can also create a solid circle by changing the value of this width parameter. So let’s look at that.

Example 1: Drawing a hollow circle.

Output :

We can create a solid circle by setting the width parameter equal to 0. 

Example 2: drawing a solid circle

Output :

Similarly, you can draw other basic shapes using the draw module of pygame. 

Drawing Polygon Shape:

The desired polygon can be drawn using polygon() function. 

Syntax: polygon(surface, color, points, width)

Again the approach remains the same only the function and the parameters change.

Example 1: drawing a solid polygon

Output :

Example 2: Drawing a hollow polygon

Output:

Drawing Line Shape:

A line is the most basic drawing entity and can be drawn in pygame using line() function.

Syntax : pygame.draw.line(surface, color, start_pos, end_pos, width)

Example 1: drawing a line

Output:

In this article, we are going to see how to draw an object using Pygame. There can be two versions for drawing any shape, it can be a solid one or just an outline of it.
