Bind AlienFX to UE4 c++ ?

Development Programming & Scripting C++
1

Hi there !

I was wondering if there were a way to gather info from Google Code Archive - Long-term storage for Google Code Project Hosting. to bind alienware lights in ue4 code … :wink:
I’m far from being able to do that myself but do you think it’d be possible ?

2

It’d absolutely be possible, but the difficulty will be dependent on the implementation of the linked software itself :slight_smile:

3

oO you mean the whole software ? I was more modest :wink: thinking about setting a simple variable to acces memory
Edit: I found the SDK, it will probably be better as I just want to have basic acces to lights
I’ll give it a try x)

4

SDK implementation is pretty straightforward, I was able to crash my lights after a few hours :smiley:

it just needs some fine tuning I guess, let’s try to get something from this new toy !

5

little update

everyhting works great, but game process freeze while lights are modified
the dll is loaded on the fly with
HINSTANCE hLibrary = LoadLibrary(_T(LFX_DLL_NAME));
The main init function takes a few seconds to be ready, I’m unsure about where to call it from, maybe the HUD, or somewhere in a begin play?. Same for the dll, I don’t understand the way to load it the correct way, I’m sure this is a 2 step process but I don’t get it.

any ideas ?

I thought a little step-throught may be usefull for some

_get the SDK in the command center directory (C:\Program Files\Alienware\Command Center\AlienFX SDK\Unmanaged\includes)
_create 2 new headers and copy paste the code in it
_copy the dll from C:\Program Files\Alienware\Command Center\AlienFX SDK\Unmanaged\dll\x64 to your project’s binaries directory
_open on of the .cpp examples and get your way through it :wink:

Mine looks like this

functions are fully documented

BE CAREFULL: you are messing with a physical chip, anticipate about initialisation and correct memory cleaning, eventuals loops and stuff like that. I don’t really know if you can brick it this way, but I was due for at least one power drain to restore it
