Doors in game engine

Game Engine Game Engine Support and Discussion

I am having a problem and can’t seem to find a solution. I know how to set a scene to change, I can enter a room, cross it and enter another door/scene. My problem is that when I reenter the first scene, I spawn back at the place where I first entered the room. Is there a way to control where the player will respawn? Is it possible to actually move the player character to other scenes without copying it to all the scenes?

You could use variables written in python and have your character linked to it

You need to store the Object status (position, properties etc.) somewhere. This is usually done with a Python controller.

You can use the SaveLoader to do that or write own code to store and restore.

example:
Transmittion.py:


import GameLogic
import copy
 
Pkey = "storageKey"
''' 
the value of this property is used as key to globalDict. 
Make sure it is unique within a scene. 
Make sure the synchrinized object in the other scene 
gets the same property value.
Default is the object name.
'''
 
def store(cont):
  if noSensorIsPositive(cont):
    return
 
  own = cont.owner
  key = own.get(Pkey,own.name)
 
  transmissionData = TransmissionData(own)
  GameLogic.globalDict[key] = transmissionData
 
def restore(cont):
  if noSensorIsPositive(cont):
    return
 
  own = cont.owner
  key = own.get(Pkey,own.name)
 
  transmissionData = GameLogic.globalDict.get(key)
  if transmissionData is None:
    return
  transmissionData.applyTo(own)
 
def noSensorIsPositive(cont):
  for sensor in cont.sensors:
    if sensor.positive:
      return False
  return True
 
class TransmissionData(object):
  def __init__(self, gameObject):
    self.gameObjectName = gameObject.name
    self.position = copy.copy(gameObject.worldPosition)
    self.orientation = copy.copy(gameObject.worldOrientation)
 
  def applyTo(self, gameObject):
    gameObject.worldPosition = self.position 
    gameObject.worldOrientation = self.orientation

usage:
Python controller in MODULE mode:
Transmission.store
before leaving the scene

Transmission.restore
after entering a scene

Make sure both objects have the same name or the same property “storageKey” with the same value.

Thanks Monster, I’ll read through the link you provided and see what I can do. I have a feeling that this is going to take a few days to figure out, that’s not a problem since I’ve spent almost two years on this game already. I’ll post here when I have more news or more questions.
