2D Motion with Structs

Here's some additional information about making your game character move in the x direction as well as the y direction.

There's a supplemental lesson in the Bootstrap 1 materials that uses a new concept called "structs" and a new function you can use called "make-posn." Read the supplemental lesson here.

If you would like to see this in action and take a peek at the Racket code, here's a link to Blank Game with just these updates. Look for the definition statement for "update-player."

Have fun with your game, and the rest of your summer!

Launch Party Day

Welcome to your launch party day!

And our final day of the Bootstrap summer program. Notice te blog entry before this one... It's your own virtual poster presentation. Tell people to check it out if you want to show off your posters and game screenshots.

Today there is no blog prompt. Write whatever you would like to say in the comments.

On behalf of the instructors, I would like to say: we will miss you and have a wonderful remainder of your summer!

Virtual Poster Gallery

Happy Wednesday! 

The blog prompt for Wednesday:

What have you gotten out of the Bootstrap program this summer?

Happy Tuesday!

Today's blog question:

If you had to explain something you learned at Bootstrap, which of these would you be most confident of? Choose from this list:

• Circles of Evaluation (and what they're good for)
• The parts of a Design Recipe
• How to Battle
• How to use the contracts page of your notebook
• Piecewise Functions
• the Pythagorean Theorem 
• Conditional branching with cond
• Collisions

Which of these would you want help explaining?

Welcome to Monday, WEEK 4 of Bootstrap

Today's prompt:

If you could choose the blog question, what would you ask? Make sure your question is about what you've been learning. So, it should have to do with:

• game programming
• programming in general
• math
• or any of the tools we've worked with

Remember, you're thinking of a blog question. Think of a question you would like to answer.

SCRATCH ONLINE!

If you'd like to explore and build with the Scratch programming language on your computer at home, go to the Scratch website, set up an account, and jump right in writing scratch programs by creating sprites and dragging blocks together.

• Scratch Website at MIT.

One fun thing about Scratch is that you can look at (and inside) other people's projects in order to learn how they work, but also to remix and customize them for yourself.

• Visit here to explore other people's animations, games, and projects.
• Or, check out this studio of three baby goat-themed games created by Mr. Burke and his daughter. These games are:
• a space invader game, 
• a dress-up game, 
• and a dodge game

After you've tried the games, open them up to see what makes the sprites tick. Change things to suit your own ideas. Remix them into your own accounts!
