This is a tutorial on '''how to create a clock'''. This clock returns the player's time because this tutorial uses the [[Current () (block)|<sb>current [ v]</sb> block]], which is local.

==Analogue Clock==

===Preparation===
To start, create three [[Sprite]]s: one for the hour hand, one for the minute hand, and one for the second hand.

{{warning|Set the costume center to any end of the lines otherwise the project will not work.}}

===Coding===


====Second Hand====
This is the script for the second hand:
<scratchblocks>
when gf clicked
forever
point in direction ((0) + ((current [second v]) * (6))) // x6 because 360/60=6.
end
</scratchblocks>

====Minute Hand====
This is the script for the minute hand:
<scratchblocks>
when gf clicked
forever
point in direction ((0) + ((current [minute v]) * (6)))
end
</scratchblocks>

====Hour Hand====
This is the script for the hour hand:
<scratchblocks>
when gf clicked
point in direction (0)
turn cw (((current [hour v]) * (30)) + ((current [minute v]) / (2))) degrees // Calculations: 360/12=30 and 1/2=0.5;0.5*60=30.
forever
wait until <([direction v] of (minute hand v)) = (([direction v] of (minute hand v)) + (6))
turn cw (0.5) degrees
wait (2) secs // This is so it would not turn 15 degrees.
</scratchblocks>

==Digital Clock==

===Preparation===
Create only one variable named "Digital Time" or "Time" to start.

===Coding===

====24 Hour====
This is the script on how to make a 24 hour digital clock:
<scratchblocks>
when gf clicked
forever
set [Time v] to (join (current [hour v]) (join [ : ] (join (current [minute v]) (join [ : ] (current [second v])))))
end
</scratchblocks>

====12 Hour====
This is the script for a 12 hour clock:
<scratchblocks>
when gf clicked
forever
if <(current [hour v]) = [0]> then
set [Time v] to (join ((current [hour v]) + (12)) (join [ : ] (join (current [minute v]) (join [ : ] (join (current [second v]) [.am]))))
else
if <<(current [hour v]) > [0]> and <(current [hour v]) < [12]>> then
set [Time v] to (join (current [hour v]) (join [ : ] (join (current [minute v]) (join [ : ] (join (current [second v]) [.am]))))
else
if <(current [hour v]) = [12]> then
set [Time v] to (join (current [hour v]) (join [ : ] (join (current [minute v]) (join [ : ] (join (current [second v]) [.pm]))))
else
if <<(current [hour v]) > [12]> and <(current [hour v]) < [24]>> then
set [time v] to (join ((current [hour v]) - (12)) (join [ : ] (join (current [minute v]) (join [ : ] (join (current [second v]) [.am]))))
end
end
end
end
end
</scratchblocks>
