Move () Steps

Not to be confused with Change X by () or Change Y by ().

Introduced in	11Oct03 (0.x)

Assuming the black grid shows individual pixel positions, moving 1 step gets the Scratch Cat to the red circle, its final position along the circle depending on its direction. Moving 2 steps gets to orange, and moving 3 steps gets to green.

The Move () Steps block is a stack block and a Motion block. The block moves its associated sprite forward by the specified amount of "steps" in the direction the sprite is facing, where a step is one pixel in length. If a negative number of steps is specified, the sprite will move in the direction opposite to its direction instead.

Like all other Motion blocks, this block is not directly accessible from the stage. If the block is imported from another sprite, the block does not move the stage when run.

Prior to Scratch 25Nov04, this block was known as "forward ()".

Example Uses

Instead of using complicated scripts with the Change X by () block and the Change Y by () block, this block can be easily used to move a sprite in its direction.

Some common uses for the block are:

• Making sprites move:

when gf clicked
set rotation style [left-right v]
forever
  move (10) steps
  if on edge, bounce

• Moving a sprite forward in an animation:

repeat (10)
  move (10) steps
end

• Making a sprite follow the mouse:

forever
  point towards (mouse-pointer v)
  move (10) steps
end

• Making a sprite follow another sprite:

forever
 point towards (other sprite v)
 move (10) steps
end
 

Workaround

Main article: List of Block Workarounds

This block can be replicated with the following code:

go to x: ((x position) + (([sin v] of (direction)) * (number))) y: ((y position) + (([cos v] of (direction)) * (number))

or:

change x by ((steps) * ([sin v] of (direction)))
change y by ((steps) * ([cos v] of (direction)))
