Overview
Two minutes, two questions:
Important points
(tommy 'go-forward!)?
No!(turtle-forward! tommy 23)
repeat!
commandMurkiness
turtle-new
and turtle-clone
.repeat!
work?
(map proc (list 1 2 3))
means call (proc 1)
,
(proc 2)
, (proc 3)
and then shove them into a new list.(repeat N proc val)
means calls (proc val)
(proc val)
, (proc val)
, (proc val)
, (proc val)
N times.
Returns nothing. Similar to (map proc (make-list N val))
, but
without the list (also more efficient).(repeat 3 proc val)
the same as (map (o proc proc proc) (list val))?
(proc val)
three times.
The second does (proc (proc (proc (val))))
.turtle-up!
and turtle down
? And what's the default?
(+ (square 5) (square 10) (square 2))
.image-stroke!
and image-select-ellipse!
. Need to think
about explicit sequencing - order of steps matters.(context-set-brush! trish "2. Hardness 100" 20)
