It’s been at least 12 years since I looked at a project, now on a different computer. It fails to compile with ‘fmod\_event.hpp’ missing. I can’t find out which version of FMOD I used. This is on Windows.

All I have is the include error and a lot of lines with these pointer defines missing: It appears to all be the event system missing.

FMOD::EventSystem \*fmodEventSystem;  
FMOD::EventProject \*fmodEventProject;  
FMOD::EventGroup \*fmodEventGroupAtmosphere;  
FMOD::EventGroup \*fmodEventGroupFoley;  
FMOD::EventParameter \*fmodEventParameter;  
FMOD::EventReverb \*eventreverb1;

I’ve tried install many different versions of Fmod, but I can’t find one with that include file or those classes.  
I can’t remember anything about Fmod, unfortunately, I just need the project to run.  
Can anyone help me?

Looks like you were using the old FMOD Designer which was superseded by FMOD Studio a number of years ago. What was your old project? Was it registered with us? Maybe I can help determine what version you might have been using.

Wow, this a late reply!  
Thanks for offfering to help all those months ago…😃  
FMod Designer rings a bell. Would it be possible to get it somewhere?

This is the project: [https://youtu.be/-L\_C3VMt4wM?si=AbBmnL1VUS9ydBNC](https://youtu.be/-L_C3VMt4wM?si=AbBmnL1VUS9ydBNC)

It’s completely textureless and with subtle sampled sounds. Making the exe only a few Mbs in size.  
It was a hobby thing, I didn’t really finish it but I wanted to compile the different versions that I have.  
I think I used FMOD’s filtering to simulate underwater sounds.

Thanks again,  
Dave

I’ve given you access to the FMOD Designer downloads.
