Test commands |
The center.posn command returns TRUE if the screen coordinates of the screen object's bottom center pixel is within a specified region.
Syntax
Remarks
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 obj.in.box) are used to determine if a screen object's position is within a certain area.
Example
if (center.posn(o1, 0, 120, 60, 130)) {
print("the object's lower center pixel is in the box");
}
