How to open a exe file with RenPy?

[slenderman64]

Hello, i try this on Renpy but it not works (he does nothing) :

Code: Select all

label OPENFILE:
     python:
         import os
         os.popen("app.exe")

There is a way to open a exe file on RenPy?

You can use subprocess.Popen. I'd suggest doing the import from an init python block, or else in a python hide block. You'll also need to give the full path to the executable.

Now my code is:

Code: Select all

label OPENFILE:
     init python:
              import subprocess
              subprocess.popen("C:/app/app.exe")

but i have this error:

I'm sorry, but an uncaught exception occurred.

I noticed that PyTom wrote subprocess.Popen while you wrote subprocess.popen
That capital P might make a difference.

It works!

now my code is:

Code: Select all

label OPENFILE:
     init python:
              import subprocess
              subprocess.Popen("C:/app/app.exe")

But, don't put "init python" inside a label.
"init" is the phase where renpy loads,and labels are executed when the game reaches them:

Code: Select all

init python:
    import subprocess
label OPENFILE:
    python:
        subprocess.Popen("C:/app/app.exe")
