RCRPG/PureBasic
< RCRPG
RCRPG/PureBasic is part of RCRPG. You may find other members of RCRPG at Category:RCRPG.
This version is a more or less direct translation of the version done in Perl (See RCRPG/Perl) with some additional functionality added. Commands include attack, drop, take, equip, alias, name, inventory, and directions. The 'name' command can use a double-quoted string if spaces wanted to be included in the name (i.e. 'name "this room").
An additional command 'ask' was implemented for providing hints in finding the randomly placed Prize Room. The program also allows the stacking of commands if they are separated by a space (i.e. 'take all equip sledge a north n' will perform four actions: take all, equip sledge, [a]ttack north, [n]orth).
A simple outlay of the play strategy is: Take and equip a sledge. Get some gold to ask for hints (from the program) and move a ladder into a room to go up if necessary and attack walls to make exits.
;Here is a description of all of the commands:
;
;north
;south
;east
;west
;up
;down
;
;Move in the direction specified. The player won’t be able to move if there isn’t
;an exit in that direction.
;
;attack (direction)
;
;Attack in the direction specified. (Equip the sledge first.)
;
;drop {all|(item name)}
;
;Drop the item specified. Or drop everything the player is carrying.
;
;take {all|(item name)}
;
;Take the item specified. Or take everything in the room.
;
;inventory
;
;Display everything the player is carrying.
;
;name (name)
;
;The player can rename the room with this command.
;
;equip (item name)
;
;Equip the item in question.
;
;alias (existing command name) (new command name)
;
;Give an existsing command an alias. Starting aliases are n,s,e,w,u,d. i and inv
;are the same as inventory, a is the same as attack.
;
;At the start of the game, only two rooms exist, the Start and the Prize room.
;All other rooms the player creates by moving around. The Prize room is randomly
;located each game. If you need a hint just 'ask'.
;
;To move out of the start room, the player needs to break a hole in a wall,
;ceiling or floor. The sledge is needed to do this.
;
;There are three kinds of items in the different rooms: sledges, gold and
;ladders. A sledge is needed to gain access to rooms the player doesn’t have
;access to. A ladder is needed to move between levels.
;
;Every room, except the prize room, may randomly have gold, a sledge and/or a
;ladder. The player will have to leave the ladder behind when they go up a level,
;so they may have to hunt around a bit for a new ladder.
;
;When the player finds a ladder, they can either move up a level from that room,
;or they can take the ladder and drop it in a room that’s more convenient.
;
;The player can make their way to the Prize Room but there's nothing
;useful there; just gold.
