Week 5- Math Theme: Z coordinate (Altitude & 3-D view)
Names: ___________________________________
Spaceland is tilted on its side. Use the
‘alt’ key and the mouse to get a 3D view.
You can also use an invisible agent with
‘take camera’ to have the Spaceland set
up in this view.

Description
Make one agent at a higher altitude than the terrain, use
the ‘Alt’ key and move your mouse to see the 3-D view.
Make 20 agents scattered at the same altitude above the
terrain.
Create 20 agents scattered at various altitudes above the
terrain. Make a 2nd breed with a single agent, make it an
invisible agent & take the camera (try setting your
invisible agent in different locations to find the best view)
Create 20 agents scattered at various altitudes above the
terrain. Have them move around and ‘float’ in the water
like plankton (move forward and slightly up & down)
Scatter 20 agents at the same altitude above the terrain,
have them fall to Spaceland like rain and stop when they
hit the terrain.
extra challenge: when the agents hit the terrain, it looks
like snow on the ground.
Create 200 turtles at random x, y, and z coordinates.
Have them wiggle around the world and wiggle up and
down. Have the turtles change color if they collide with
another turtle.
Hints
Work only in the World page, and only a Setup push button
is needed, use a trait block to set the altitude.

Work only in the World page, and only a Setup push button
is needed, use a trait block to set the altitude, use a random
block to have various altitudes. To make an invisible
agent, set its size to zero, use the block ‘take camera’ to see
Spaceland from its view.
Once the 20 agents are scattered, work in the Turtle page
with a ‘forever’ block. In the movement drawer, find the
‘up’ and ‘down’ blocks, use random blocks to make each
agent move at different rates. (sort of like a vertical wiggle)
To have them fall, use a ‘down’ block and to stop they can
be deleted using a logic block ‘if’ to create an equation with
their Z (if their Z is less than or equal to, then delete)
Think of the epidemic model and explore whether the
‘collision’ block works in 3D.
