Games::PMM::Monster::Commands - class abstracting monster commands
my $commands = Games::PMM::Monster::Commands->new(
Games::PMM::Monster::Commands presents a nice interface to the set of commands a monster will execute. You will probably never need to use it directly, though, unless you're hacking on Games::PMM::Monster.
Monsters understand several commands. This list will grow in the future, both in size and in complexity.
Moves the monster one square forward, depending on the monster's current facing.
Moves the monster one square backward, depending on the monster's current facing.
turn [ left | right ]
Turns the monster in the given direction, from the monster's point of view. This only changes the monster's facing, not its position.
Looks for other monsters in the current monster's field of vision. Only those monsters in front of the current monster (per its facing) and those directly beside the monster are visible. In the following diagram, * represents the current monster (facing north), M represents a visible monster, and . represents an monster that is not visible.
If the monster were facing east, the visible positions would be:
Beware that scan does not track seen monsters. The monster will remember the position of monsters it sees but it will not update those positions as those monsters move.
Moves or turns the current monster one step toward the nearest monster that has previously been seen (via scan). Monsters prefer to walk toward a position in the direction they are facing, turning only when they cannot move closer by moving forward.
Moves or turns the current monster one step away from the nearest monster that has previously been seen (via scan). Monsters prefer to backwards from a position, turning only when they can back up no further.
Causes the current monster to attack another monster one position ahead, left, or right of the current position. If this attack connects, it will damage the other monster.
new( [ @commands ] )
Creates and returns a new Commands object. The arguments are optional. Any arguments are treated as raw, unprocessed commands. They will be processed and stored within the object.
Returns the next available command. Commands are returned as a list, with the first item being the name of the command and subsequent items being the arguments to the command.
This will return undef if there's a break in the commands, as when reaching the end of a command list.
No known bugs.
