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 Image model, don't worry! You can use the provided model.

Go to https://stretch3.github.io/ and start a new Scratch project and delete the Cat sprite.

Then, add the TMPose2Scratch extension by clicking on the Extensions button at the bottom left corner of the screen and selecting TMPose2Scratch. This extension allows you to use Google Teachable Machine pose models in your Scratch projects.

When you add this extension, it will automatically try and use your computer's camera. If necessary, click on 'Allow' to give it permission to use your camera. You should see what the camera is showing in the stage area.

Scratch: How to add extension blocks

Scratch Extensions make it possible to connect Scratch projects with external hardware (such as LEGO WeDo or micro:bit), sources of information on the web (such as Google Translate and Amazon Text to Speech), or blocks allowing for more advanced functionality.

When an extension is enabled, its blocks appear in a location with the same name as the extension.

To load an extension, click the icon in the bottom-left hand corner of the screen and select an extension.

Add the Rocketship sprite to the project and then add the following code to it, to shrink it's size and position a the bottom center of the stage area.
