1 - Start: What We're Building ~4 mins
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.
Before you change anything, look at the plan for the rocket and stars. How do you think a tilt pose will make the rocket move?
Open the project you saved earlier (or start fresh in Stretch3 as guided). You will predict, build, run, and fix as you go.
2 - Introduction ~3 mins
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.
3 - Setup Scratch and Tmpose2scratch ~3 mins
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.
4 - Add the Rocketship Sprite ~2 mins
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.
when green flag clicked
set size to (40) %
go to x (0) y (-150)
5 - Load Teachable Machine Model ~3 mins
Now, let's set up the pose model that our project will use. Add the following new code to your sprite:
when green flag clicked
set size to (40) %
go to x (0) y (-150)
