vector2

This topic is about the vector2 data type.

Value syntax

vector2 v2 = {1.3,-2};

Syntax notes

Previous assignment syntax can be used only during initialization. The following code will raise an error.

vector2 v2;

v2 = {1.3,-2};

After a vector2 is declared, it can be populated either by using the implemented API listed below or by assigning it the values from another vector2.

vector2 v2;

vector2 vv2 = {1.3,-2};

v2 = vv2;

Description

Vector2 type is an array of two double values. It is used for properties such as 2D positions.

• The default value is {0,0}.

• Vector2 type partially supports arithmetic and comparison operators.

Autocasting

Vector2 type supports automatic conversion for

• string, if in the correct input format (space separated list of two numbers); otherwise, it will raise an exception.

  vector2 v2=”1 2”; //v2={1,2};

Properties

These are the properties for vector2.
