From: Harishankar Date: Fri, 7 Oct 2011 10:45:52 +0000 (+0530) Subject: Implemented NPC movement (random) X-Git-Url: https://harishankar.org/repos/?a=commitdiff_plain;h=667ea7c15261100aae75b61de8664863b58f01e4;p=butaba-adventures.git Implemented NPC movement (random) Added random movement for NPCs in level based on a limiting area. NPC cannot move on solid tiles, or tiles with objects, where other NPCs are standing and also where Butaba is standing --- diff --git a/butaba.py b/butaba.py index ca44883..d9237ca 100644 --- a/butaba.py +++ b/butaba.py @@ -1,17 +1,18 @@ # Main player Butaba class +import constants + class Butaba: - # Position definitions - LEFT = 0 - RIGHT = 1 - FRONT = 2 - BACK = 3 - MAXITEMS = 8 - MAXHEALTH = 100 # initialize our character - def __init__ (self, startrow, startcol, position=LEFT, health=100, magic=1, experience=1, strength=1, gold=0, inventory = []): + def __init__ (self, startrow, startcol, imageleft, imageright, imagefront, imageback, portrait, + position=constants.LEFT, health=100, magic=1, experience=1, strength=1, gold=0, inventory = []): self.position = position + self.imageleft = imageleft + self.imageright = imageright + self.imagefront = imagefront + self.imageback = imageback + self.portrait = portrait self.row = startrow self.col = startcol self.magic = magic diff --git a/constants.py b/constants.py index 18111c6..a37f3d3 100644 --- a/constants.py +++ b/constants.py @@ -1,5 +1,16 @@ # constants for in-game use +# butaba constants +MAXITEMS = 8 +MAXHEALTH = 100 + + +# describing the orientation of characters +LEFT = 0 +RIGHT = 2 +FRONT = 1 +BACK = 3 + # key ids and lock ids KEY_CHEST1 = 1000 KEY_CHEST2 = 1001 diff --git a/dialogues/bulisa4.dlg b/dialogues/bulisa4.dlg index 2674783..d439c59 100644 --- a/dialogues/bulisa4.dlg +++ b/dialogues/bulisa4.dlg @@ -2,6 +2,12 @@ Ah, I see you're back with the water!
