in today's video tutorial we're going to 00:00:00

be learning about how to use the 00:00:02

if statement blocks using the online version 00:00:04

of scratch as you can see a 00:00:06

new project open for the purpose of 00:00:08

today we're going to be using four 00:00:11

different tabs the looks tab events control 00:00:13

and then sensing i'm going to start off 00:00:17

by navigate 00:00:19

get into the control tab and selecting 00:00:20

the different blocks that will be using 00:00:22

those blocks are the if then block 00:00:24

and if then else block with 00:00:26

these blocks essentially we will be saying is 00:00:29

that if something happens such as our 00:00:31

mouse pointer is touching our cat sprite 00:00:35

then we want this action 00:00:38

then to occur 00:00:40

and in order to use this one 00:00:42

it's essentially the same but what we're 00:00:44

saying is if our mouse pointer 00:00:47

is touching the cat then we want 00:00:51

this action to occur otherwise we want 00:00:53

a secondary action to occur let's go 00:00:57

ahead and go back up to this 00:01:00

first block and look at that first 00:01:01

so in order to get a spot 00:01:04

to work we're going to need a 00:01:06

couple of things first we're going to 00:01:07

need the action that we want to 00:01:09

happen 00:01:11

let's go to looks and say that 00:01:12

we want 00:01:16

this sprite to hide when the mouse 00:01:18

pointer is touching it 00:01:22

what we need to do in order 00:01:24

to get this to work is we're 00:01:25

going to have to navigate to the 00:01:27

events and we can select when clicked 00:01:29

and scroll down to control and put 00:01:33

this in a forever loop 00:01:35

we're also going to need to go 00:01:38

back to looks and select show otherwise 00:01:40

when the mouse would be touching the 00:01:43

cat he would just be hidden forever 00:01:45

because of the forever loop so let's 00:01:48

go and select show 00:01:52

one things here 00:01:56

so when clicked 00:02:00

when clicked i want my cat sprite 00:02:05

to show and when my mouse pointer 00:02:07

is touching him i want him to 00:02:11

hide the simple as that now let's 00:02:12

go ahead and move on to the 00:02:16

next block 00:02:17

going to go ahead and throw back 00:02:18

that show and keep her forever whooped 00:02:21

throw this one back and we're going 00:02:29

to select the second if statement block 00:02:31

we're back in the forever loop 00:02:34

we're going to stick with this touching 00:02:37

mouse pointer 00:02:39

and we're going to say that we 00:02:41

want him to 00:02:44

hide 00:02:48

and then show 00:02:49

so when clicked 00:03:08

we want this cat to hide when 00:03:10

the mouse is hovering over it otherwise 00:03:13

we want it to show 00:03:16

and you can also do other things 00:03:19

with this as well we can swap 00:03:21

out the hide for let's say change 00:03:24

costume 00:03:28

or next costume 00:03:30

so when clicked 00:03:34

we want this cat to change it's 00:03:36

costume 00:03:38

when the mouse pointer is on it 00:03:41

otherwise we just want him to show 00:03:43

his regular costume the first one and 00:03:44

we know that the second costume would 00:03:47

be him running because we can navigate 00:03:49

to the animal sprites and we can 00:03:52

see by scrolling down here to the 00:03:55

cat 00:03:57

that when we hover over this we 00:04:01

see him moving 00:04:03

and that concludes our video tutorial for 00:04:05

today 00:04:07
