Ok. Here’s my problem.

I have 2 scenes. The first scene is my actual game. The second is an overlay, with a meter on it. Now this meter has a property that keeps on changing.

I need an object from the first scene to copy THAT property. Now, i know you can’t copy properties via logic bricks in different scenes, SO… i wrote this.

scene = GameLogic.getCurrentScene()

activeScenes = GameLogic.getSceneList()

objList = activeScenes.objects

meter = objList["Power"]

c = GameLogic.getCurrentController()

owner = c.owner

power = meter['Power']

copy = owner['Power']

copy = power

The object i want to copy from is called Power. Plus, both the properties are called Power.

I get this message on my screen:

AttributeError: ‘list’ object has no attribute ‘objects’

(Its refering to this line:
objList = activeScenes.objects)

Any help would REALLY be appreciated.

Thx.

getSceneList() returns a list of scenes, not a scene.

You must first pick a scene out of it to access that scene’s own list of objects.

3

activeScenes = GameLogic.getSceneList()
results in activeScenes which is now a list of scenes.

objList = activeScenes.objects
makes no sense as activeScenes is a list not a scene, so you get an error.

If you know the name of the overly scene you can do this:
overlayScene = GameLogic.getSceneList()[“otherScene”]
or
meterObject = GameLogic.getSceneList()[“otherScene”][“OBPower”]
or
powerProperty = GameLogic.getSceneList()[“otherSceneName”][“OBPower”][“Power”]

finally you can write


import GameLogic
owner = GameLogic.getCurrentController()
owner["Power"] = GameLogic.getSceneList()["<i>otherScene</i>"]["OBPower"]["Power"]

Do not forget that object names start with “OB”.

I hope it helps

getSceneList() returns in 2.49a and 2.49b at least a standard list which cannot be accessed by scene name.

So to get scene by its name in this case:


import GameLogic

owner = GameLogic.getCurrentController().owner

for sce in GameLogic.getSceneList():
    if sce.name == "otherScene":
        owner["Power"] = sce.objects["OBPower"]["Power"]
        break

Unfortunetly, I tried the codes and it didn’t work…

It doesn’t tell me there is an error, so I don’t know what i did wrong…

Btw, the other scene is called Overlay.

Do globalDicts work between scenes? If so than you can use those.

7

Er… it should work. Exept i’m not too good with those. You wanna give me a hint on that?

8

Just type:

GameLogic.globalDict[“name”] = value

to store, and

value = GameLogic.globalDict[“name”]

to get your value back

You can put anyting in for values, numbers, lists (, I even used it to store a complete rigid body constraint :smiley:)

I just don’t know if I ever tried it between scenes.

@supersocks
You are right :slight_smile: I forgot it’s a standard list

Turkey-Killer have you replaced the “otherScene” with “Overlay”?
