Thanks for the feedback! Game Lab has a lot more capabilities than are covered in the curriculum and it’s great your students are interested in exploring them. I can answer questions about Game Lab and bring back the curriculum feedback to the team.
Not all Game Lab features are available in every lesson, but if you go to studio.code.org/projects/gamelab/new or click the “Make a Game Lab project” button at studio.code.org/projects, you’ll get access to all the features of the tool.
In code, sprites have properties of
height. These have examples if you hover over the blocks in the “Sprites” toolbox. There are lots of ways to handle resizing, but I like using
scale because it keeps the sprite’s aspect ratio. In the animation tab, images can be resized using the purple tab on the right.
The green “debug” boundaries are outlines of a sprite’s collider. Custom colliders can be set for sprites and do not have to match the sprite’s shape. For an example, hover over the
sprite.setCollider() block in the “Sprite” category in Game Lab.
Hope that helps,
