3. In the Create New Node window that appears, search for and select the expression AnimatableBody2D in the Search line and click on the Create button.
4. Create a new Node by clicking the + sign under the Scene tab or the Ctrl-A keys.
5. In the Create New Node window that appears, search for Sprite2D in the Search line, select it, and click the "Create" button.
6. With the "Sprite2D" Node selected, drag and drop the assets\sprites\platforms.png file from the "FileSystem" tab to the "Texture" section under the "Inspector" tab.
