keeping the same variables for another scene?

Game Engine Game Engine Support and Discussion

on the main menu for my game, you can change the settings and one of those is mouse sensitivity. So there’s a integer property for sensitivity and you can change it. I need a way to transfer the value into the other scene. Anyway I could do that?

I use GameLogic variables for things like that. You could setup a dictionary of settings and reference that. Pop it into a startup script on the splash scene and it’ll always be available.

E.g.


GameLogic.settings = {
"mouseSensitivity" : 0.01,
"movementSpeed" : 4.0
}

You can also check if the variable exists before redefining it, so you don’t reset your changes.

E.g.

if not hasattr(GameLogic, "settings"):
   GameLogic.settings = {
   "mouseSensitivity" : 0.01,
   "movementSpeed" : 4.0
   }

You can store this information in any module:

MySettings.py:


mouseSensitivity = 0.01,
movementSpeed = 4.0

you can read the values:


import MySettings
mouseSensitivity = MySettings.mouseSensitivity 
movementSpeed = MySettings.movementSpeed

and change


import MySettings
MySettings.mouseSensitivity = 0.05
MySettings.movementSpeed = 10.0

The module will be creates with the first import and lives as long as the game lives (except you unload it explicitly).

Yeah, I didn’t know about the ability to use other modules, but it works, and it works well. You could, for example, store map data in a Map.py file (it obviously has to exist beforehand), or put player information in the Player.py file. It’s really useful. The power of Python strikes again. :cool:

Thanks guys! Working great now! And I learned about the power of the hasattr() function.
