Eng:Change X by () (block)

The Change X by  block is a Motion block and a Stack block. The block moves its sprite costume center's X position by the specified amount. The x axis ranges from -240 to 240.

Example Uses
when gf clicked forever if  change x by (-5) end if  change x by (5) when gf clicked go to x (-240) y (([sin v] of (-240)) * (100)) //240 is the leftmost position of the stage clear //clears a previously drawn wave, if it exists pen down //draws the first point of the wave repeat (480) //the width of the stage is 480 x coordinates pen up //so the movement to the next position is not interfered with an unintended, out-of-place line change x by (1) //the use of the block set y to (([sin v] of (x position)) * (100)) //the result is multiplied by "100" to expand the amplitude for visual preference pen down //creates the mark
 * Often in games, the player controls a sprite and moves it around the Change X by  block (and the Change Y by  block) are very common in this event.
 * This block can also be used to move a sprite which creates a sine wave (see Trigonometry) along the x axis. An example script of this situation is:

Workaround
This block can be replicated with either of the following codes:

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