Porting Opposing Force or Blue Shift to Source?

Technology and Gaming
#1

I was curious, is it possible to port an older GoldSrc game such as Opposing Force or Blue Shift to the Source engine similar to Half-Life: Source? I figured that it might be a neat project to look into in my spare time. I honestly thought the Source port of HL1 was pretty decent and the concept of updating a game to that extent really intrigued me.

So do any of you know if it’s possible? If so, what would be involved? Would it be as simple as taking out the GoldSrc maps, converting them to Hammer, then adding in all of the game’s other assets?

I wouldn’t be distributing the game if I could get it to work. My only intention for this would be for something me to do over the next few weeks.

Nono, he’s talking about porting stock Opposing Force and Blue Shift. Nothing to do with the remakes.

At the very least, you’ll have to convert all the maps into BSPs (which I hear is really easy, there’s a built in function in Hammer that does that), and then you’ll probably have to make entities in your new source code (especially for the Race X aliens, which definitely don’t exist in the publicly available version of Source).

It’s called the compile button. :stuck_out_tongue:
They’re already BSPs, just not Source BSPs. Not sure how you’d go about converting that without decompiling the maps.

Of course, you’d have to decompile the maps anyway to add stuff like physics and such.

It’s definitely possible, but you’ll be in for a major headache as far as the maps go, unless you can manage to get the source files from Valve. (Or Gearbox, if they still have a copy)

Model decompiles are more accurate, usually, but you’d need to set up each character model to ragdoll properly if you want to take full advantage of the porting process- that’s a pain when you’re on your own, though you can probably find some documentation for it somewhere.

Good luck!

In addition to recompiling maps, you’d have to convert the textures, recompile models, rig them properly and add source entites and sprites to the maps. Some of the models and textures you can get from hl :s ource though.

The specific purpose of Half-Life: Source was to show to modders how easy it was to port content from the gldscr engine to source engine. So yes a port is possible. The problem is having the pre-compiled game code for non-stock half-life code.

The question is, why port them over? Most people tell others to when buying a copy of HL to buy the basic one because there is barely any advantage to it.

Plus, the Source version of HL doesn’t support all the original game’s mods. So yeah, kinda pointless unless you MUST use Source for something (like demo recording, if you’re Ross Scott).

For fun, nothing more.

It doesn’t support all dude and If you know th, have you tried playing GoldenEye:Half Life 2. I just love playing it.
