Week 9 – 3/28/15

We will be well on our way to present our games at the STEM fest with this homework!  Please email Michael if you feel that you need help.
What I want you to get out of the assignment is that when you use glide you go from point A to pt B and you can’t effect the sprite as it glides. But if you use a loop and decrement the y position you can now put an if statement in the code. You already have all the code from the last class.
Assignment:

Please keep on working on your game for the STEM fest.

I have shared a project that you can use for the exercise. If you go to backdrops, you can find a background of an x-y axis. You might find this helpful.
1. Make an x and y axis on paper and plot the the following point (0,0), (1,1), (-3,-2), (5,-2)
Please use the shared link for the rest of the homework. The ball has two costumes: a blue and yellow costume.
2. In Scratch, make the ball  go to (100,100) using the blue costume.
3. Now make the  ball go from (100,100) to (100, -100)  using the glide command.
4. Now, what if we want the costume to change from blue to yellow  when  the y value is between 50 and -50.  If the ball is outside of 50 and -50, it should go back to blue. Can we do this using glide? Why not?
5.  Instead of using glide you can use a loop to move the ball. How do we have the costume change as specified in part 4?
Below is a representation of how the ball color should be changing based on its height.
Blue
Blue     —- change happens when y value is below 50
Yellow
Yellow
Yellow
Blue   —- change happens again when y value drops below -50
Blue

Week 8 – 3/21/15

Next class we are going to be building structures in Minecraft. The code would look like something like this:
mc.setBlock(x, y, z, block_type)
So for example:
mc.setBlock(100, 200, 300, 3)
would mean to set a block at position:
x=100
y=200
z =300
block_type =3 —> dirt
I’d like you to write some code to print out numbers. In class I will show you how we can modify this code with very little extra code and build walls. It’s all about “for” loops.
Do a search on Google for “python for loop and nested for loops” if you want a refresher. There are tons of good videos. It’s a great habit to use Google to help you learn. I use it all the time.
A. write a program that will print out the following using a for loop:
1
2
3
4
5
6
7
8
9
10
B. Write a program that will print out the following using a nested for loop:
1 1
1 2
1 3
2 1
2 2
2 3
3 1
3 2
3 3

Week 6 – 3/7/2015

In class we went over how to write a function for our hangman game that will take a word as an input and then return a string with the correct number of underscores. For example
“banana”   —->  “_ _ _ _ _ _ _ _”
Now write a function that takes 3 inputs. First_Name, Middle_Name, and Last Name and returns a string which is the initials.
Lets call the function “Initials”
 Initials(“Michael”, “Zvi”, “Liebis”) —–> “MZL”
Some help:
if you have a string
x = “Michael”
x[0] is the first character or “M”
Test out this code:
def sum(x,y):
return x+y
s = sum(2,3)
print s

Week 6 – 3/7/2015

Scratch:
As we discussed in class, be prepared at the next class to make a proposal for the group project. I want you to at least have some graphics (no code) in place so you can explain how the “game” will work.
Python:
Write a program that asked the user for a password (That only you know and have put into the code). If they get it correct it prints out “Welcome” otherwise it prints out “You do not have Access”
