I want to launch an external app with arguments clicking a button with Playmaker actions ...

for Example , can i launch

Hi.
Are you looking for something like this?

https://answers.unity.com/questions/16675/running-an-external-exe-file-from-unity.html
If so let me know, i can see if i can make an action for it.

hello djaydino ! How are you ??

Yes , exactley !! but the the actions should need to have to change paths , in this case , change the Retroarch.exe path and Roms path ...

LocalRetroarch.exe path (editable variable)\retroarch.exe -L ( fixed arguments) Libretrocore.dll RomPath (editable variable)\Romname.zip

Is possible I've solved with ProcessStart.info method in a C# script, and it works, but it should be better to use a single Playmaker Action ...

It is possible for you ?

thanks !!

hi djayadino !!

I've tryed the action "build string" and then send to "WWW object" action , but the program doesn't start .... what's wrong

[djaydino]

Hi,
Sorry for the late reply.
Can you show the target string it uses

[markettounity]

hi !!

the format of the command line is :

[retroarch path]\retroarch.exe -l [Core emulatore path]\Fb_neo.dll [Rom path]/gametoplay.zip

I need 2 Global variables for the [retroarch path] and for [Rom path] editable by 2 input fields in options menu , and then save by Playerprefs action.

so, what is your solution ?


As alwasys ... thank you

[Maart]

Buildstring will let you use multiple inputs 2 of them could be variables

Hello Mart !!

I 've follow your instructions , but once i created the string , what i have to do next ??

"WWW object" action ??

thanks !!

I think this is a better solution for you
it will allow you to run an exe file from an action and you are able to pass arguments
I tested it with scummvm, the test I did uses an argument to start monkey island full screen. (I didn't have retroarch) but you get the point
Can someone add this to the ecosystem?

[Maart]

the build string solution you can use to build a string like C:\Program Files\ScummVM\scummvm.exe then use the action OpenUrl with that string as the URL

Ok, Maart ... you are officially my super-hero !!

you saved my brain !! thaaank you very much !!
