Hi all,

May I ask why allegro pause the game if the window lost focus??

I use a while loop for running the game.
How can I fix it(as I want to create a game that will still run even the window lose focus)?

Thanks

set_display_switch_mode()

Thanks for your reply.

I have tried set_display_switch_mode(SWITCH_BACKGROUND) under window xp, but still when the window lose focus, the sound delay to play and the whole game stop.

What's going wrong?

A couple of questions..
What platfrom are you running the application on?
What is the return value of set_display_switch_mode()?

Not all modes are supported on all platforms, I can only suggest that you setup your code so that you try the variety of background modes in the most preferable order. Then you either dont use video bitmaps, or be prepared to reload them when you get the display switch callback. (set_display_switch_callback())

If you solve the problem in this way, it will work on more platforms without you having to modify your code.

Thanks for your reply.

>What platfrom are you running the application on?
MS Window XP sp2

>What is the return value of set_display_switch_mode()?
it is 0.

Thanks

....

Thanks you all.

Finally, I found that while it did not work even if I had used set_display_switch_mode(SWITCH_BACKGROUND) under window.

It is because I wrote this code before "set_gfx_mode" = =

Anyway, thanks again
