Sam B's 2% time padlet by Sam Bessey

I am using pygame to make my game in python

The first video I watched

y2029sambes3 — 2024-02-02 13:40:54 UTC

I was going to add a background like this, but then I changed my mind.

y2029sambes3 — 2024-02-02 13:41:55 UTC

I might add it again later, but it isn't a priority

I use rectangles a lot in my game.

y2029sambes3 — 2024-02-02 13:42:39 UTC

Collisions are when you check whether two rectangles are touching.

y2029sambes3 — 2024-02-02 13:43:44 UTC

This is very important for most video games, including mine.

In pygame, you can use masks to check for collisions in images with transparent backgrounds.

What I added this week

y2029sambes3 — 2024-02-13 23:01:45 UTC

•A countdown at the start to be sure everyone starts at the same time.

•A finish line!

•Improved collision detection

Questions

y2029sambes3 — 2024-02-13 23:04:13 UTC

How can I make a video game in python? How easy is it to make a video game? How long will it take to make a video game? Is python a good language?

Timer

y2029sambes3 — 2024-02-13 23:50:55 UTC

I am adding a timer to see how long it took you to finish. To do this, I create a variable called speed. Then I set the variable to the current time minus the time when the countdown finished. Then I round this to the nearest tenth of a second and print it onto the screen.

What I added this week

y2029sambes3 — 2024-02-13 23:55:20 UTC

•A timer!

•Background music

•Middle barrier to reduce cheating

•Saving the high score!

Current High Score

y2029sambes3 — 2024-02-13 23:57:32 UTC

31.9

Staying on your side

y2029sambes3 — 2024-02-14 23:39:27 UTC

You used to be able to cross over to the other player's side and just press the button to go forward. You wouldn't have to steer, because the game only checks for collisions on your side. I fixed this by adding an invisible barrier in the middle, so no one can cross over.

High score

y2029sambes3 — 2024-02-16 15:32:06 UTC

I wanted the game to save the high score even when you close and reopen the game. This meant I couldn't just make a variable, because that would reset each time you play the game. Instead, what I did was save it to a plain text file that would be accessed each time the program was run. Also, whenever the game ends, it will check if the current score is better than the old high score. If it is, it will save it to the file.

•The message saying who won now takes up the entire screen, instead of a bar at the top.

•The course is now longer

What I added this week

y2029sambes3 — 2024-03-13 22:44:52 UTC

•A second course!!!

•No more driving over the walls!

•better acceleration

•driving backwards

A second course!

y2029sambes3 — 2024-03-13 22:47:53 UTC

Much easier than the first course! In the future I am planning to add even more.

Better acceleration

y2029sambes3 — 2024-03-13 22:51:25 UTC

Now, you slowly accelerate instead of speeding up all at once. You can also control your speed and drive in reverse.

What I added this week

y2029sambes3 — 2024-03-18 22:19:43 UTC

•A message saying to press space

•Pick course screen

•Playing multiple times

Press space message

y2029sambes3 — 2024-03-18 22:21:15 UTC

Often when people are playing my game, they don't know that they need to press space to start the countdown. I added a message that appears before the countdown starts that says to press space.

Pick course screen

y2029sambes3 — 2024-03-18 22:53:35 UTC

I have had two courses to race on for a few weeks, but this week, I added a screen where you can pick which you want to use. This opens every time I run the code.

Playing multiple times

y2029sambes3 — 2024-03-21 18:30:44 UTC

It was annoying to quit and rerun the code each time I wanted to play the game again. So now, you can play multiple times!

What I added this week

y2029sambes3 — 2024-03-24 17:37:39 UTC

•A fullscreen button

•A quit button

• One-player mode

One-player mode

y2029sambes3 — 2024-03-30 17:22:22 UTC

What it does, is it checks if it can move forward. If it can, it does. If it can't, it checks if it can go left; if it can, it does go left. Otherwise, it goes right.

Countdown

y2029sambes3 — 2024-03-30 18:08:21 UTC

It shows each number, and waits 1 second after displaying it on the screen.

Turning

y2029sambes3 — 2024-04-28 19:11:32 UTC

You can now turn the actual car! This is a big improvement over the car just moving sideways, which looked weird. I originally tried to rotate the image in the code with pygame.transform.rotate, but that only works when rotating in 90º increments. Otherwise, it completely glitches. So what I had to do instead was make a different image for each way that it rotates and have it switch between the images whenever you press the button.

Things to do

y2029sambes3 — 2024-05-05 15:35:05 UTC

I finished everything!

What I added this week

y2029sambes3 — 2024-05-05 15:39:31 UTC

•Turning the car

•A new course

•Updated it so I can add bigger courses later.

What I added this week

y2029sambes3 — 2024-05-06 13:44:47 UTC

•Not getting stuck on the walls

•Changed font on game over screen

•Added message when you set a new high score

•Fixed turning glitches

•draw_text improvements

Game end screen

y2029sambes3 — 2024-05-08 17:54:08 UTC

The game end screen looked messy and off-center, so I wanted to improve it. Before, I had an image that said:

Player 1 wins!

Time: seconds

High score: seconds

Then, I would draw the text inside pygame, but only the numbers. Now I write all the text inside pygame, which makes it look so much neater! The reason I was able to center the text is the improvements I made to the draw_text function (see previous post) so I provided the center coordinates instead of top left, like before.

draw_text improvements

y2029sambes3 — 2024-05-08 17:56:01 UTC

I improved the function I use to draw text on the screen.

Before:

def draw_text(text, font, text_col, x, y):
text_img = font.render(text, True, text_col)
screen.blit(text_img, (x, y))

After:

def draw_text(text, font, text_col, x, y, transparent=True, topleft=False, surface=screen): if transparent == True: text_img = font.render(text, True, text_col) else: text_img = font.render(text, True, text_col, BG) blitloc = text_img.get_rect() if topleft: blitloc.topleft = (x, y) else: blitloc.center = (x, y) surface.blit(text_img, blitloc)

Now, I can choose whether or not to give the coordinates for the center or give the coordinates for the top left. This helped me make the game end screen a lot neater.

What I added this week

y2029sambes3 — 2024-05-20 13:30:26 UTC

• A new course

• Mud patches

• Settings menu

• Save settings

Settings menu

y2029sambes3 — 2024-05-20 13:37:00 UTC

I zoomed out the courses to 0.8 so you could see what's coming next, but some people like it better zoomed in, so I made a settings menu so you could change the zoom level. I used the same animated button as the OK button on the game end screen for Save, but with different text drawn on it.

What I added this week

y2029sambes3 — 2024-06-02 19:56:07 UTC

• Separate high scores for each course

• Updated menu

• Various bug fixes

Updated menu

y2029sambes3 — 2024-06-02 19:59:47 UTC

Originally, the menu at the top of the screen was just different images. Now, I am changing all the buttons throughout my program to rectangles in pygame instead of separate images. This will make it easier to edit them.

Separate high scores!

y2029sambes3 — 2024-06-02 20:00:47 UTC

High scores are saved in a text file. I made 3 different text files, so each course could have it's own high score.

What I added this week

y2029sambes3 — 2024-06-02 20:01:37 UTC

• Better keyboard input

• Fixed more bugs!

Keyboard Input

y2029sambes3 — 2024-06-02 20:08:09 UTC

In pygame, there are a few types of keyboard input:

• get_pressed: This is just true or false depending on whether a certain key is being pressed.

• pygame.TEXTINPUT: This is used for typing something into a text field. I don't use this in my game.

• pygame.KEYDOWN: This is true or false depending on weather a key was pressed in that frame.

I made turning the car use pygame.KEYDOWN instead of get_pressed. This means that now each time you press the turn button you turn, instead of having to hold it down for a few seconds.

CODE SO FAR:
