Drive a ship in homeworld1

[smallfishlxy]

Hello everyone,
I download HW1 source code from the relic RDN site,
and I want to add some code to HW1 to control a ship,
like some fly games,but the whole program is too completly,
I dont know how to start,and if I finished it,could I upload the files on here?

[Ghost3021]

First off....
Yay! Someone else who got the source and is *trying* to do something with it!
Second....
Ehh well quite frankly there's no code at all for accepting inputs from the keyboard, at least when it comes to the ships....see, last I checked, ships are essentially just AIs that do what you tell them to...so taking one over would be difficult
Third....
I suggest getting the stupid thing to compile before trying anything else :P
Fourth...
I don't think so, but a patch is probably doable (users of HW:Source must register and agree with RDN's liscense agreement)

[Caboose123]

although you have the source code, unless you know HOW to code that into the source code i doubt its do-able

oh and ghost? the members of this forum (as far as i know) have already tried without success to mod using the sourcecode, trust me if they could it would have been done by now

but a simple fix would probably be to export one of the ship models into a space game such as freespace etc. but DONT distibute it if you do , or youll be in a bit of trouble

[Sastrei]

There's always pilotview.

But Homeworld is an rts, not an space/flight sim, the structure is completely different.

-Stefan-

[Fiirks]

/pilotview to the shortcut.

Select and zoom in on a single ship ingame, press Q. Later, rinse and repeat.

[smallfishlxy]

I have made some changes,use mouse and numpad keys to
control the ship.

[Sastrei]

omg.

-Stefan-

[Babbo]

Yes, me too: omg! What does the rectangle in the middle of the pictures mean?

[Ghost3021]

Woah!
>_>


<_<

[Delphy]

I think unless and until somebody posts source code, that just simple pictures are not enough evidence.

[Riess]

This is too good to believe it. I request a release of some sorts.

Homeworld Access provides hosting, I suggest contacting Homy there.

[Fiirks]

Wow, you managed to attract delphy.

Looks pretty cool, but you'll definetly have to explain how and post some code here if people are going to take this one seriously...

[Caboose123]

i too would like to see that, can you fire?

[smallfishlxy]

To Babbo :
The rectangle is used to help aiming.

At the beginning,I feel very difficult to complie,and follow the wmake to change files
one by one,the sound, bink video and cdkey not working,I just make them return TRUE when they are called.when complie succeed,you can track the game using debug tools,find out where recive the keyborad press,where give the ship a command,
where manage the command,how to execute the command and use what kind of
method,where give the ship force and torque,where calculate the position,then add some keys to control the force and rotate,when the ship is controled,make other parts of the game skip it.but the target is reserved,when you set free the ship,make it controlable to the main game,
that's all.

[Fiirks]

Could you post specific instances of the code where you did all this please fish? I'm very interested in this and if you could explain so that others could replicate the process....

[4E534B]

Shiny. Looks good to me, though I haven't tied it. So now you need to implement firing, right? That could get a bit rough

[Babbo]

Thanks & gggreat! But how to implement these things as a 'normal' user Couldn't you reflect upon the possibility to provide your work as a mod?

[Fiirks]

Holy shit. Babbo, I don't think you could mod the normal homeworld.exe to do this without having to compile the whole thing yourself.

Lord delphy, will it please you to try this yourself and give us an objective report on it?

[Caboose123]

wait, so even IF this is released as a mod, ill have to compile it myself?


...

[Ghost3021]

I share Caboose's concern - I STILL havne't gotten the stupid thing to compile...

[the zapkitty]

wait, so even IF this is released as a mod, ill have to compile it myself?

As I understand it you can realease a binary of the modded code as long as you include the proper accreditation and warnings. It will still be Relic's property of course.

Indeed, going strictly by the RDN license you must agree to in order to access the source code, you're not supposed to release the raw HW source code itself, or mods thereof, to anyone but RDN members

http://homesource.nekomimicon.net

I share Caboose's concern - I STILL havne't gotten the stupid thing to compile...

There is, of course, a cross-platform port of the Homeworld source code that does compile and work on Windows, Mac, and Linux:

Homeworld SDL

The ship pilot code looks interesting, but I'm busy reconciling the latest HW-SDL stuff with Linux right now

http://homesource.nekomimicon.net

Why is the forum joining my posts when I filled out two separate message forms?

[ceejayoz]

Why is the forum joining my posts when I filled out two separate message forms?

Because we don't like double posts here.

smallfishlxy, any chance of releasing a .exe?

[smallfishlxy]

ceejayoz :
If you are the member of RDN,I could email the exe file to you,
that will not break the software lisence I think.

the part of mouse control in the mainrgn.c and force control in the univupdate.c
is not based on the knowlage of hw:source,so I have rights to put them here.

to Ghost3021 :
may be the verson of compiler is newer than the hw:source has,some data types
and define method changed,and some link options in the makefile needs change,
they are different between systems.

[Fiirks]

I am indeed a member of the RDN, if you could email me the files I would be very appreciative.

tim.peacock "at" gmail.com if you could include instructions, I suppose its not quite as simple as just replacing the homeworld.exe or is it?

[the zapkitty]

ceejayoz :

?

As I said above, distributing binaries to non-RDN members isn't a problem.

Actually, the various HW source code projects have been distributing binaries.

It's the uncompiled, raw, source code that's supposed to be under (rather draconian) lock and key.

... the part of mouse control in the mainrgn.c and force control in the univupdate.c is not based on the knowlage of hw:source,so I have rights to put them here.

The mods here, and over at Homesource, have been easy about code snippets and, for all the holy terror that the RDN EULA represents if it's strictly interpreted, Relic has actually been OK so far on practical issues.

Which is good as it's difficult enough edging along the vast pit that Relic Legal carved to protect themselves without well-meaning folks trying to turn it into an IP singularity that sucks everything in and leaves nothing behind...

Of course trying to post all of UnivUpdate.c in an open forum could cause an... unfortunate response

http://homesource.nekomimicon.net/

[Caboose123]

so how does that help this guy finish and release this "mod"

[the zapkitty]

so how does that help this guy finish and release this "mod"

I'd think it would just be an extension of the way we'd already been handling such.

He bundles notices with it that it's derived from Relic code, that it is itself Relic property and covered by their end-user licenses etc...

edit: the "we ownz this" part of the licenses, not the "we iz responsible" parts... as it should be obvious even to a Windoze user that Relic ain't responsible for anything the modded binary actually does or doesn't do

... amd that folks must already have bought and installed the game "Homeworld" for this to work, add any installion instructions and "ain't no guarantees or warranties here" notices he sees fit to add... and turns it loose.

He might send a polite notice to Relic that yet another HW-derived binary is hitting the net, but they shouldn't object.

If he needs a place to host the binaries for downloads... well... that's part of what I created the Homesource site for in the first place

http://homesource.nekomimicon.net/

[smallfishlxy]

sorry Fiirks ,my computer infected visus yesterday or earlyer,all the exe files been modified,so i dont think it is safe to transfer the exe file or zip files on the net,and the source code is diffentfrom the game in the market,you should complie it by your self,read it carefully before run,you'd better install it in a single hard drive that not link to interenet,if you have problem to complie,I could help you.

[4E534B]

What the heck??? the SOFTWARE PRODUCT and MODIFIED SOFTWARE can be distributed to RDN members only (!) Be careful with this...

EDIT:
okay, I'm building [RELIC's] (working, I mean fixed by me) HW now, lemme see the code.

EDIT2:
Okay I got the thing running up.

EDIT3:
Nah, it refuses to compile. I think there are some unresolved referenes, or maybe the code is incomplete. Are you sure you modified only that?

[the zapkitty]

What the heck??? the SOFTWARE PRODUCT and MODIFIED SOFTWARE can be distributed to RDN members only (!) Be careful with this...

Calm down. You are years out of date

As I said above, the strict interpretation of that damned EULA means you can do absolutely nothing with the HW source in any meaningful sense.

but...

We have had verbal assurances from Relic, repeatedly, that that wasn't what they really meant.

Here's a response from Ron Moravek of Relic.

"I guess the main point is that people can do whatever they want with it, share it etc, but they cant make a profit based on our code without our agreement. The only way to do this is to have Relic own everything, then, with our agreement, they could go on to make and do whatever they want with it."

So, as I said, all your binaries are belong to Relic... and anything else you add to a mod... but they really don't want it:

"...they can release the code as they please as long as its for non commercial use. The intent is that no one makes profit and nothing damages the franchise. They can pretty much do as they please as long as it doesn't generate cash or infringe."

So not only are we not 'living dangerously' with the binaries distribution stuff, we're actually being conservative compared to what has been said is allowed by Relic...
...
... but in software license stuff conservative is good

So if fishy can get themselves dewormed, I can host their ship pilot binary and you all can download and play it without selling your soul to Relic.

Y'see... we already did that so you wouldn't have to

http://homesource.nekomimicon.net/

[Fiirks]

Sell my soul? I didn't get it back from Riess yet.

Also, this is way cool, but I'm going to wait until I hear from somebody that the actual stuff works on another compliation of it...

[Caboose123]

is there a program that i could use to compile the source code with fish's code attached

do i have to overwrite anything in the sourcecode?

can anyone e-mail me a copy so i dont get confused? (should be in my profile, or shoot me a pm)

lol, i can picture relic shouting: all your binaries belong to us!!!!!!!!

EDIT: shame Microsoft isnt so leniant, "Halogen, well miss you!!!"

[smallfishlxy]

I suggest start a new title named "compile the HW:source",it doesn't need to chage much
in the source,just need your patient .It's funny that drive the mother ship to anywhere

[Derivative]

So is there any new information about this mod, or is it going to fade into rumored obscurity?

[King of Hearts]

all your binaries belong to us!!!!!!!!

You mean:

All your binary are belong to us!!!!!!!!

[Jianaran]

if someone could email the .exe to ninthlegion "at" gmail "dot" com i would greatly appreciate it.

[smallfishlxy]

I host the exe file at
http://www.hwaccess.net/forum/viewth...=99&rowstart=0
it is a debug verson.

[Caboose123]

can you release a version in a single file, i cant extract the files properly

[Derivative]

How can I make a short video clip from a game? Screenshots just don't do justice for this mod.

[Caboose123]

i guess FRAPs would be the easiest answer, though the quality is quite poor and you can only record for about 30 seconds

[Derivative]

Okay, I've made three video clips. I'm not familiar with the key settings of the mod, so I didn't use all of them. They are uploaded on my brother’s youtube account.
Here they are:
First
Second
Third

[Riess]

Wow. I am impressed, the Scaffold flythrough was great. Good job, smallfish.

[Homdax]

ehem, smallfixly, yo may have it there in a forum, but You hardly host it.

GG anyway, damn what did I miss :o

Ok, now I get it, why are you called smallfixly here and bigfixly there?

[Tefeari]

Shame that you can't fire .

You can't right?

[Riess]

Press T.

[Homdax]

:wow:

[smallfishlxy]

Hi Riess,what happend after press T?

[Babbo]

She fires.

[Caboose123]

i just figured out i didnt need to download all 14 files for the mod to work, i think this is the best damn mod in existence, if it'll work in conjunction with other mods i think i gonna faint...

also you can tell the ship to attack an object and fly near it, the ship'll automatically open fire.

and one question, is it possible to change the speed of the ship youre flying instead of going at full speed all the time, and to stop?
