in this tutorial we are going to 00:00:00
use logic comparisons these are comparisons for 00:00:02
which the outcomes true or false first 00:00:05
we go to operators and we select 00:00:08
this script here we compare only ask 00:00:10
is the last number less than the 00:00:14
right number and the answer is either 00:00:16
true or false 00:00:18
the next one is greater than we 00:00:20
ask as the last number greater than 00:00:22
the right number and the answer is 00:00:24
true or false the next one is 00:00:26
an equal comparison we ask is the 00:00:28
last number the same value as the 00:00:30
right number and the answer will be 00:00:32
true or false we can use the 00:00:34
outcome of these comparisons to control some 00:00:36
actions so to do this 00:00:38
we need to go to motion and select turn 00:00:40
clockwise and next from the control menu 00:00:42
we will need forever and if then 00:00:46
finally from sensing we want to use 00:00:53
distance to also don't forget to click 00:00:56
the green flag 00:01:00
first of all we want to turn 00:01:04
the sprite continuously for example one degree 00:01:06
at a time forever 00:01:09
here you can see that the sprite 00:01:12
continuously turns without any type of control 00:01:14
now we want to make the sprite 00:01:25
turn when a certain condition is true 00:01:27
for example 00:01:30
we can use the less than operation 00:01:34
and distance to mouse pointer less than 00:01:37
for example ninety then turn one degrees 00:01:40
the distance to the sprite is measured 00:01:45
from this point and this example we 00:01:48
can see zero zero ninety here 00:01:50
equal to three boxes so when the 00:01:53
mouse is more than three boxes away 00:01:56
from the script it will not turn 00:01:58
the as you could see when we 00:02:00
bring them as close to the sprite 00:02:01
it starts to rotate and when we move it 00:02:03
away it stops 00:02:06
next we can try another comparison if 00:02:12
we use the more than 00:02:15
so if the distance to the mouse 00:02:17
pointer is more than here you can 00:02:20
see that if the mouse is close 00:02:23
to the sprite it doesn't move but 00:02:25
when the mouse moves further away from 00:02:26
the sprite it starts to move 00:02:28
the last comparison is equal to the 00:02:35
distance has to be exact for the 00:02:38
sprite to move 00:02:40
let's choose ninety again 00:02:42
so here we can see that the 00:02:50
mouse has to be exactly three boxes 00:02:52
away otherwise the sprite will not rotate 00:02:55
this is quite tricky to find 00:03:04
so here we have seen how to 00:03:21
use comparisons of less than greater than 00:03:23
and equal to 00:03:26
