CPoint:Offset

The Offset method moves a point to new coordinates. The offset can be specified in several different ways and can be positive or negative. The + Operator gives similar results.

Syntax

CPoint:Offset( CPoint2 )

CPoint:Offset( x )

CPoint:Offset( x, y )

where

CPoint2 is another CPoint object.

x is a single offset applied to both values.

x and y are offsets applied individually to the CPoint values.

Example

The following script moves and resizes the CPoint P using various argument lists. Note that CPoint:Get returns 2 arguments, which can be automatically filled into the 2 fields of the Printf function if located as the right-most item in the Printf argument list.

P = NewRect(100, 200)	-- create a CPoint object P
Printf("%lg %lg\n", P:Get())	-- result: 100 200.

P:Offset( 2, 10 )	-- move and resize the point P
Printf("%lg %lg\n", P:Get())	-- result: 102 210

P:Offset( 0, 30 )	-- resize the point P
Printf("%lg:%lg\n", P:Get())	-- result: 102 240

P:Offset( 100 )	-- move the point P
Printf("%lg %lg\n", P:Get())	-- result: 202 340

P:Offset( 10 )	-- move the point P
Printf("%lg:%lg, %lg:%lg\n", P:Get())	-- result: 212 350

Pnew = NewRect( 0, 60 )	-- create another CPoint object
P:Offset( Pnew )	-- resize P using another point
Printf("%lg %lg\n", P:Get())	-- result: 212 410
