Type Stack

The Set X to () block is a Motion block and a Stack block. The block changes the selected sprite's X position to a specified value. Along with the Set Y to () block, this block acts similarly to the Go to X: () Y: () block.

Example Uses

If a sprite's Y coordinate must be held constant, but the sprite still needs to move (for example, a horizontal scrollbar), the Set X to () block may be used instead of the Go to X: () Y: () block — there is no need to set the Y position when it does not change.

This block is often used in projects that employ X scrolling — specified sprites constantly change their X positions to follow the motion of the landscape.

Other uses include:

  • Setting the location of sprites to a random position on the screen
when gf clicked
set x to (pick random (-240) to (240))
  • Setting random locations for sprites so as to fill the screen (for example, a snowflake project)
  • Resetting the X-coordinate of a slider
when I receive [reset slider value v]
set x to (0)
  • Moving a paddle in a Pong game
when gf clicked
set x to (mouse x)
