Introduction to TNG
It is a block programming language.
Breeds play a more important role.
Buttons in runtime workspace.
Procedures and variables are created
differently from Starlogo 2.
Agent monitors still here.
Task 1
Find the following blocks, move them
out to the canvas. Once you have done
so, remove these blocks from the
canvas.
Task 2
Make the turtle agents in Spaceland
move forward, right, and forward again.
Task 3
Make your turtle agent walk forever.
Task 4
Make the turtle agent move forward
when you press the up arrow on your
keyboard.
Hint: computer needs to check for key
presses constantly.
Task 5
Now make the turtle agent respond to other
keys, left to turn left, and right to turn right.
Task 6
Create a procedure called “Movement”
and have it enclose the keyboard control
movement you created for your turtle
agent.
Try moving your turtle agent again with
the keyboard.
Task 7
Create a variable “Steps” and assign it a
random value from 1-10
Task 8
Use your “Steps” variable to determine
the number of steps forward your turtle
agent now makes in your “Movement”
procedure.
Task 9
Add a parameter to your “Movement”
procedure and call it “Angle”
Use the “Angle” parameter to determine
the amount your turtle agent turns left
and right
Task 10
Add a new breed of agents.
Name them “cubes”
Choose a cube shape for the new breed
of agents.
Task 11
Create 8 more cube agents.
Hint:
Task 12
Create a procedure called “wander” for
the cube agents.
This new procedure should make the
cubes walk randomly across Spaceland.
