Errata

Missing segment at 32:21

There is a missing segment at 32:21, where I changed the project’s window settings. These settings control the resolution and the way the game window scales. Here’s how to change them.

Go to the menu Project -> Project Settings.

In the left column, scroll down to Display -> Window, and click on Window to open the window settings on the right side.

Here are the settings I changed. In the size section at the top. These settings control the resolution of the game and size of the window:

• Width: 1920
• Height: 1080
• Test Width: 1280
• Test Height: 720

Then, scroll down to the stretch section and set:

• Mode: 2d
• Aspect: expand

These two settings will make the game viewport resize with the window. Without them, when you increase the window size, more of the game level would show. The expand aspect setting makes it so when you change the ratio of the window, it shows a little more or less of the game world to preserve the proportions of the game sprites. You can play with these settings to see the differences they make.

Change in value at 1:02:26

At 1:02:26, the line 13 of Player.gd changes: the value 1.0 turns into 0.0, but it’s not mentioned in the video.

You should also change this value. The line should be:

-Input.get_action_strength("jump") if is_on_floor() and Input.is_action_just_pressed("jump") else 0.0
