Linking interscene properties?

Hi everyone, i am looking at making a health bar and a mana bar, however i am displaying these by overlaying a second ‘HUD’ scene. i would like to know how to link properties from the first scene to the second so that when a ‘bullet’ hits the player in the first scene then the health property will go down and hence, so will the health bar on the second scene?
Thanks,
Lediron

If you are using only logic bricks you can use messages.

If the player lost health send a message with the message actuator, and in the HUD scene put to your bar a message sensor, when the bar receive the message, reduces the health value.

If you are using python, you can get the objects from the other scene or use the globalDict.

The BGE Guide to Messages incl. Healthbar tutorial should help :).

Ok cool thanks, much appreciated
