You can already train a pose model. Today you will load that model into Scratch and build a space game you steer by leaning left and right.
You will start a new project in Stretch3 and build the game step by step, testing and fixing it as you go.
Before you touch any code: how would leaning your body to one side make a rocket move across the screen?
In this lesson, you will create a fun Space game using Scratch and Google Teachable Machine.
You will learn how to use your Teachable Machine Pose model with tilt poses to control a spaceship.
If you don't have a Teachable Machine Pose model, don't worry! You can use the provided model.
Set up a new project in Stretch3 with the TMPose2Scratch extension:
- Go to https://stretch3.github.io/ and start a new project.
- Delete the Cat sprite.
- Click the Extensions button at the bottom left of the screen and choose TMPose2Scratch (not Posenet2Scratch or TM2Scratch). This extension lets you use Google Teachable Machine pose models in Scratch.
- The extension tries to use your computer's camera straight away. If your browser asks, click Allow. You should now see what the camera shows on the stage.
Add the Rocketship sprite to the project and then add the following code to it, to position it at the bottom centre of the stage area and shrink its size.
