Drawing a whole flower
Page 17Look at this picture:
Does it look familiar? It's built with the leaves from the previous page. Can you draw it? Try to Think Turtle.
Here's how I drew it. First I made LEAF take a parameter. Like this:
REPEAT 2 [CIRCLE 100 :x RT 80]
END
That's just because I wanted a bigger bloom. You could do it with the old LEAF too. Then I drew the bloom like this:
Let's call it BLOOM:
REPEAT 12 [RT 30 LEAF 2]
END
(Can you make a bloom with more petals? With less petals? Can you make BLOOM 4 mean a bloom with 4 petals?)
Now you can draw a whole flower. Maybe it could look like this?:
You don't need my help to draw that. You can do it all on your own.
These are the words we know now. They are the same as on the last page:
| Logo word | What it means |
|---|---|
| FD 100 | Walk forward 100 steps |
| BK 100 | Walk backward 100 steps |
| LT 90 | Turn left (good for drawing squares) |
| RT 90 | Turn right (good for drawing squares) |
| LT 120 | Turn left (good for drawing triangles) |
| RT 120 | Turn right (good for drawing triangles) |
| CS | Remove everything you have drawn |
| HOME | Move back to the starting point (and draw a line) |
| PU | Lift the pen so you won't draw when you walk |
| PD | Put the pen towards the screen again | REPEAT 10 [ ] | Repeat what's in the box 10 times |
| SETPC 4 | Change the pen to pen number 4 | TO ... END | Remember the word after TO in the future |
| ; | Don't listen to me now | PRINT [I'm a turtle!] | Say "I'm a turtle!" |
| RANDOM 10 | Choose a number from 0 to 9 | WAIT 60 | Wait for 1 second. |
| PRINT 2+2 | Makes the turtle say 4 | TO SQUARE :top | Put 5 in your :top pocket when I say SQUARE 5 |
| REPCOUNT | The number of the repetition |
These are the words we have taught the turtle. BLOOM is new:
| New Logo word | What it means |
|---|---|
| SQUARE :top | Draw a square |
| CIRCLE :x :size | Draw a circle |
| STAR :number :length | Draw a star |
| LEAF | Draw a leaf | BLOOM | Draw a bloom |
