Eng:Change Y by () (block)

The change y by  block is a Motion block and a Stack block. The block moves its sprite's Y position by the specified amount.

Example Uses
Often in games, the player controls a sprite and moves it around, such as with velocity. In this way, the Change Y by  block (and the Change X by block) can become very useful. The y axis ranges from -180 to 180. set [yVelocity v] to [0] forever if  then change [yVelocity v] by (2) end if  then change [yVelocity v] by (-2) end change y by (yVelocity) if <(yVelocity) > [0]> then change [yVelocity v] by (-1) end if <(yVelocity) < [0]> then change [yVelocity v] by (1) end end
 * In this script, which could control a paddle in Pong, a yVelocity variable controls the sprite's up and down movement. This allows the sprite to accelerate and decelerate.

Workaround
This block can be replicated with the following scripts:

set y to ((y position) + (change))

go to x: (x position) y: ((y position) + (change))

define change y by (value) //run without screen refresh set [pastDirection v] to (direction) point in direction (0 v) move (value) steps point in direction (pastDirection)
