*A
Returns
The value pointed at by a pointer stored in A
This operator is also called the dereference operator, since it takes a pointer reference and gives you the value within.)
When using the & operator to get a reference pointer, you can access the value it points to with this version of the * operator. This can also be used on the left-hand side of assignment operations, for instance *A = B or *X += Y, to store the result in the place the pointer indicates.
atom/proc/PixelPos(px, py) // get an exact step position
*px = (x-1) * 32 // this code assumes a 32x32 icon size
*py = (y-1) * 32
atom/movable/PixelPos(px, py) // get an exact step position
..()
*px += step_x // this code assumes a 32x32 icon size
*py += step_y

var/X, Y
PixelPos(&X, &Y)
usr << "You are at [X],[Y] on level [z]"Note
If you try to read to or write from a pointer reference that is no longer valid, such as to a var inside a proc that has ended, the read or write will fail silently; reading will return a null value. (An exception is pointers to list items. If the index is out of bounds, you will get the expected error.)
