Port script to BGE 2.5 (BPY api 3)

Game Engine Game Engine Support and Discussion
#1

Hi everyone!
Having seen how helpful the community of BlenderArtists are, i was wondering if there was anyone out there who could help port these scripts (movement, and ray shooter with bullet spawner) to the new blender 2.53 GE?!
I am having no luck:( Looking in Blender 2.49b console window still to no avail.
Bullet script:


import random
import math




# Get controllers
controller = GameLogic.getCurrentController()

# get the spawner's reference name
spawner = controller.owner
target_colider = controller.sensors["Target Colider"].owner

# Get sensors
ray = controller.sensors["ray"]
running = controller.sensors["run"].positive
fired = controller.sensors["fire"].positive
reload = controller.sensors["reload"].positive
scope = controller.sensors["scope"].positive


# Get actuators
recoil = controller.actuators["play_recoil"]
scope_in = controller.actuators["scope_in"]
#define variables
isFiring = False
ammo = getattr(controller.owner, "ammo")
clips = getattr(controller.owner, "clips")
scopeval = False
canfire = True
#define event
if scope:
    if not running:
        scopeval = not scopeval
        canfire = not canfire
GameLogic.addActiveActuator(scope_in, scopeval)
                    
        
if reload:
        if clips > 0:
            if ammo < 1:
                setattr(controller.owner, "clips", clips - 1)
                setattr(controller.owner, "ammo", 200)

    if not running:

#                  This script has been written regarding                      #
#                   to a problem I noticed about blender.                      #
#                                                                              #
#                                                                              #
#     First, you got to know that when you create an object, you need to       #
#    specify "where"... which isn't a problem cuz usually, when you create     #
#       something, you have a good idea of where you want it to be. The        #
#     "spawning location", which is where your object will appear in the       #
#     game, is usually the center of another object (usually an empty for      #
#    "no-collision" purposes). When you do that, you tell blender to seek      #
#     for the center of the empty (Or the kind of object you choose) and       #
#        create your object there. Problem is that blender does have a         #
#      little "gap"... meaning that he will look for the location of the       #
#    object "FROM LAST FRAME". Therefore, blender will create your object      #
#   where your spawner* was one frame before. Since there's about 60 frames    #
#     each seconds, this gap doesn't seem big... but it is : A gap of one      #
#   frame from a spawner moving at 10 blender unit (meters) per second will    #
#     get a gap of 10/60 = .166 meters = 17 centimeters = bullet spawn way     #
#  off from the weapon and the player is not happy.... nor as the programmer.  #
#                                                                              #
#                                                                              #
#   To avoid this, I tried many way... but nothing simple seem to have any     #
#   impact on this problem : it's just the way blender think. So, to get rid   #
#    of this problem, I just offset the "spawner" from a distance relative     #
#  from the actual velocity of the spawner's parent. Therefore, the spawner's  #
#    position is approximately one frame ahead. So, if blender only consider   #
#     the position of the spawner one frame late, it's gonna be the actual     #
#    frame. And yes, the trick work. BUT, there is still a gap between the     #
#   created object and it's supposed location. This is due to the fact that    #
#  the approximation used to move the spawner one frame ahead does not take    #
#  the acceleration in consideration. Thus, the approximation would gain lot   #
# of precision by considering the acceleration, but relating to the fact that  # 
#    blender doesn't seem to already calculate it (not like the velocity),     #
#  there would be a need to calculate the acceleration from the 3 precedents   #
#   positions. These calculations could slow down the game and I will avoid    #
#  including them to the script as long as the gap isn't to bad... or until    #
#      I discover that the requested calculation power isn't that big.         #
#                                                                              #
#                                                                              #
#      Since the spawning point of the bullet may be set randomly anyway,      #
#        no need to get crazy about the exact supposed position of the         #
#        spawner : 10 centimeters off the weapon is quite too much, but        #
#                a few millimeters is pretty much reasonnable                  #
#                                                                              #
