Global_local

Global locals refer to variables that every
object has, but can store different values per
object.

Below is an incomplete list of global locals already defined by ENIGMA
and GM:

• x - the object's x (horizontal) coordinate in the
  room. 0 is the leftmost part of the room, with positive numbers
  going to the right.
• y - the object's y (vertical) coordinate in the
  room. 0 is the topmost part of the room, with positive numbers going
  down (in this sense, the y axis is flipped from what we would
  normally expect).
• id[1] - a unique identifier for this instance.
• sprite_index - the sprite currently
  assigned to this object.
• mask_index - the
  collision mask currently assigned to this
  object.
• image_index - the current animation
  subimage, where 0 is the first subimage.
• image_speed - the animation speed, in
  subimages per step. 0 indicates no animation.
  Values between 0.0 and 1.0 will animate slowly, causing some
  subimages to display for multiple steps. 1 indicates normal
  animation (1 subimage per step). Values greater than 1 will animate
  quickly, causing some subimages to be skipped.
• image_number[2] - how many subimages
  the current sprite has.
• image_single (deprecated) -
  Combination of image_index and image_speed, where -1 indicates
  normal animation, and >= 0 indicates that image_speed should be 0
  (no animation) and image_index should be the value. Since this
  variable is deprecated, use of it can lead to unpredictable results.

• image_xscale - horizontal scale factor
  of the sprite. 1.0 indicates normal size, 0.5 indicates half size,
  2.0 indicates double size, -1.0 horizontally flips the image.
• image_yscale - vertical scale factor of
  the sprite.
• image_angle - Angle to rotate the sprite,
  counter-clockwise, in degrees. 0 indicates no rotation.
• image_blend - Blending
  color of the sprite. Black creates a silhouette,
  white preserves the original image.
• image_alpha - Alpha transparency of the
  sprite. Values between 0.0 (fully transparent) and 1.0 (fully
  opaque).
