in today's video tutorial we're going to 00:00:00
be learning about the three repeat options 00:00:02
that we have using the online version 00:00:05
of scratch we'll also be introducing a 00:00:07
new block called the touching block that 00:00:10
can be found under the sensing tab 00:00:13
so as you can see i have 00:00:15
a new project open i have it 00:00:17
named and it 00:00:19
saved let's go ahead and navigate down 00:00:20
to the control tab and select those 00:00:23
three repeat block options that we have 00:00:25
the three options are repeat a certain 00:00:28
number of times repeat forever which would 00:00:32
also be repeat continuously so nonstop and 00:00:36
then re 00:00:39
repeat until the repeat until a block 00:00:40
is a little bit more interesting with 00:00:43
this block what we're saying is that 00:00:45
we want an action to be performed 00:00:46
such as moving ten steps until 00:00:49
another action happens so we'll get into 00:00:54
this one in a minute i'm going 00:00:57
to go up to this first block 00:00:58
here 00:01:00
the repeat ten times block so the 00:01:00
action that i want repeated is ten 00:01:04
steps by using this repeat a certain 00:01:06
number of times a block i am 00:01:09
saying that i want this cat sprite 00:01:11
to move ten steps ten times so 00:01:13
around ten 00:01:16
there we go simple and of course 00:01:19
i can change this number if i 00:01:21
desire 00:01:23
next let's take a look at the 00:01:27
forever block again forever as i said 00:01:29
just a moment ago as nonstop so 00:01:32
when i plug this in the cat's 00:01:34
going to move nonstop until he is 00:01:36
right off the screen 00:01:38
now let's go ahead and look at 00:01:43
this last one 00:01:45
so with the repeat until block what 00:01:48
i want is for this cat to 00:01:50
move ten steps and tell another action 00:01:52
is performed and that's an action that 00:01:55
you're going after program for two days 00:01:58
example we're going to go down to 00:02:01
the sensing tab and we're going to 00:02:03
select the touching block to use 00:02:05
this i need to drop it right 00:02:07
here in this hexagon shape that's lit 00:02:09
up and then i have to figure 00:02:10
out what i want the action to 00:02:13
be or in this case what i 00:02:14
want the cat to touch 00:02:16
for today i want the cat to 00:02:18
touch another sprite so the cat will 00:02:20
move ten steps until it touches a 00:02:23
second sprite let's go down here to 00:02:25
this panel and choose our second sprite 00:02:28
how about the jellyfish 00:02:32
i need a place the jellyfish directly 00:02:37
in front of the cat otherwise he 00:02:39
won't stop when he's supposed to 00:02:41
so now that i have the jellyfish 00:02:46
fish placed directly in front and gleaned 00:02:47
a click back on the cat sprite 00:02:49
so i have my code and then 00:02:51
i have to go to this touching 00:02:53
block and i have to select jellyfish 00:02:55
so when i click on this i 00:02:57
want the cat to move ten steps 00:02:59
until he touches the jellyfish 00:03:01
and there we go simple and that 00:03:05
concludes today's video tutorial 00:03:07
