Test commands

The right.posn command returns TRUE if the screen coordinates of the screen object's bottom right pixel is within a specified region.


right.posn(obj oA, byt X1, byt Y1, byt X2, byt Y2)


Test commands are only valid in an if statement.

The region to be tested is bounded by (X1, Y1) - (X2, Y2).

The position test commands (posn, center.posn, right.posn, and are used to determine if a screen object's position is within a certain area.

if (right.posn(o1, 0, 120, 60, 130)) {
  print("the object's lower right corner is in the box");
