NewRobotType definition
NewRobotType new_type { IsLikeA old_type ; }
NewRobotType new_type { IsLikeA old_type ; enhancements }
To define a new robot, you must use the NewRobotType
statement.
This defines a new
robot type
(new_type) to be based on another robot type (old_type).
The enhancements, if given, are what differentiate one type from another
and can consist of
DefineNewInstruction,
DefineInitialBeepers, and
DefineInteger statements.
The
IsLikeA
must be the first statement in the
NewRobotType definition block. One is never used without the other.
The definition must come before any executable statements, so it is placed
within a
define block.
The NewRobotType definition can also be specified using
new_robot_type.
Example 1:
define
{
NewRobotType another_bot
{
IsLikeA basic_bot;
}
}
execute
{
new basic_bot karel at 1,1;
tell karel:
{
if (FrontIsClear) Move 1;
TurnOff;
}
new another_bot twin at 3,3;
tell twin:
{
if (FrontIsClear) Move 1;
TurnOff;
}
}
Example 2:
define
{
NewRobotType beeper_bot
{
IsLikeA basic_bot;
DefineInitialBeepers 5;
DefineNewInstruction turnright as
{
iterate 3 times TurnLeft;
}
}
}
execute
{
new beeper_bot kathy at 5,4;
tell kathy: turnright;
}
