Control Block
These are looping blocks which are used when the same blocks have to be repeated for a
number of times. The most commonly used control blocks are:
wait 1 seconds block pauses the running of the script for the number of seconds given in the
block. You can use this block when two move or speak blocks are coming one after the other.
The repeat block repeats a set of blocks for a given number of times. This repeat 10
block is also used to draw shapes where we have to give the same blocks
again and again for a number of times.
The forever block keeps on repeating a set of blocks till the Stop button is forever
clicked. This block is similar to repeat block and expands automatically to
accommodate the blocks you snap inside it.

SETTING THE SPRITE POSITION
The stage is divided into different values of x and y. Each dot on the stage is made up of both x
and y values. The value of x gives the horizontal (left to right) location of the Sprite. The value
of y gives the vertical (top to bottom) location of the Sprite. The centre of the stage has x and
y values as 0.
go to x: -100 y: -34 block helps you to fix the position of the sprite at the beginning of a script.
Sometimes due to some scripts, the sprite goes beyond the stage. This block helps to bring the
sprite to the desired location.
