Tur:C Bloğu

Translate: - English - Türkçe - 한국어 

'C bloklarının genel şekli'.

Bir C bloğu "C" harfine benzeyen bir bloktur, böylece diğer bloklar içine girebilir. These blocks perform the conditions and loops.

Shape

C blocks have a "mouth" (it looks like the letter "C", hence the name) — the blocks that will be played with the C block go in these mouths. All but one of the C blocks consist of one mouth — the other, If () Then, Else, consists of two mouths. When any of the other C blocks are dragged over a stack of blocks — if the C is empty — its mouth extends to wrap around them.

(1) saniye bekle

end
(Meow v) sesini bitene kadar çal
end

In 1.2.1 and earlier, C-block scripts could only be built one block at a time.

Blocks

In Scratch 2.0, there are five C blocks, and they can all be found in the Control category.

• Forever
• Repeat ()
• If () Then
• If () Then, Else
• Repeat Until ()

The Forever If () block.

In Scratch 1.4 and earlier, there was also a Forever If () block. It was replaced with its workaround.

Uses

As C blocks are for checks and loops, they are used almost everywhere. Some uses include:

• Things that must go on forever

yeşil bayrak tıklandığında
forever
turn cw (15) degrees

• Checking a condition

when [space v] key pressed
if <(loudness) > [30]> then
stop [all v]
end

• Repeating an animation a certain amount of times

when gf clicked
repeat (200)
turn ccw (36) degrees
change [color v] effect by (1)
end

Here is an example for both checks and looping:

when I receive [Decrease health v]
change [Health v] by (-1)
if <(health) = [0]> then
repeat (8)
change [color v] effect by (25)
end
end

• Starting/Stopping

when gf clicked
if<key [space v] pressed?> then
stop [all v]
else
end

There is a check (the If () Then block is checking if the variable Health has a value of 0), and inside the check is a repeat loop (with the Repeat () block). Note how C blocks can be placed inside other C blocks.
