{RELEASE} The VIPER RAIDER, a pirates favorite ?

[dertien]

Without further ado, here's the release of a remake from one of Griff's models. Enjoy and test it as you see fit and please give me feedback on bugs should there be any.

The Viper Raider... A pirates favorite ?

"With the rising success of the Viper craft as a workhorse in the police force and its equally prohibitive price and availability on the market, the conception of a similar craft was of course inevitable" the chief of police of Biarge said. A craft sharing distinctive features with the Viper was captured last week by police near the witchpoint of Biarge, a rich industrial world in the southwest of galaxy 1. Preliminary analysis showed that the pilot of the craft; who remains to be found; activated his escape capsule for reasons unclear, leaving his undamaged craft up for grabs. Where the craft was built and by whom it was designed is yet to be determined. The sudden appearance of it though is still shaking the foundations of the more law abiding systems within Biarge's 7 year light radius, and some less scrutinizing folks already pointed the finger at the world of Vebege, an anarchy who's techlevel is adequate for ship construction and design and within 1 jump of Biarge.

The following facts have been released by the local police spokesperson:

It has a reverse-engineered Cobra-Mk3 Powerplant with a different and fuel rich-burn cycle, therefore its nacelles will glow up orange instead of blue. The other fact is that the hull is based on the standard patrol viper with a lowered wing profile.

Since there is a non-disclosure agreement between Viper's builders and their customers, it is unclear at the moment if this craft outperforms its corporate namestake. The tabloids already gave it the ringing name "Viper Renegade" and the trader's league is warning their transport pilots to take on an escort or two extra just in case.

"As a warning to all pilots and not only to traders", the chief said, "the police has released a spec sheet of the Viper Raider, which will give you a good idea of what you're up against should you encounter a pirate flying one of these." "I wouldn't be surprised if these craft were sold through backwater shipyards in anarchy systems either." he added.

- Laser: 1 Slot
- Missile slots: 4
- Maximum energy: 256
- Cargo Capacity: 10 std tons
- Flight Pitch: 2
- Flight Roll: 3.8
- Thrust: 55

I am sure as the story will develop further we will be able to bring you even more facts. This was Hugh Janus live from Biarge.

*** specifics ***

- New Viper variant with different 3d model based on Griff's viper.
- New texture kitbashed from a number of craft in the Griff's all in one oxp
- Different Orange Glow color for the engines. (works only with full shaders on)
- Minor Glitch (a little part of the gun as seen from the top is transparent, It doesnt affect gameplay and its a minute bug)

*** Debugging ? ***

Found something I can fix ? leave me a message on the Oolite BB, and I'll see what I can do.

*** Credits ***
A big thank you to:

- Giles Williams and contributors for Oolite
- Griff for his Viper model and his panels I was allowed to scavenge to make this ship.
- Smivs for his texturing tutorial and his general guidance with Oolite knowledge and config specs.
- All the other enthusiasts on the forum.

*** Dependables/Requirements ***

Has been tested and Works with Oolite 1.74.2 and shaders set to full. For people without shaders, please delete the "Viper_Raider_Engine_NormalMap.png" from the textures folder.

WARNING: Requires "griff_shipset_all_in_1.oxp" which can be found here: http://s248731467.onlinehome.us/griff.html

*** Installation ***

For People playing Oolite with full shader support:

Drag and drop this into your AddOns folder of Oolite in addition to the required oxp's.

For people who have set their Oolite gameplay settings on simple or no shaders, drag and drop the oxp into your AddOns folder in addition to the required oxp's AND delete or rename the file "Viper_Raider_Engine_NormalMap.png" in the texture directory.

*** Legal bollox ***

This oxp is free to use, distribute, edit or alter as you see fit without my permission. It can not be used in any commercial product and cannot be sold. It is free software and should only cost you download time. I am not in any way liable if your break your Oolite installation using this oxp. Use at your own risk. I have successfully tested it and it works 4 me.

Enjoy.

[pagroove]

Congratulated on your first own ship! Downloaded it. I like the orange engines

[dertien]

Thanks Pagroove, hope you enjoy playing it. I left enough hints where to buy it.

This gave me a good idea of what Wings 3D can do and I found out it is easier to make a model than it is to texture it. Glad I could use Griffs files as a backbone.

You can always get back to me here should you encounter any glitches. Not that I want to burden anyone with gametesting, but if you come across anything please let me know.

Game testing is never a burden... I'm flying test pilot for Smivs atm, and loving every minute.

[dertien]

Been playing for at least an hour now instead of testing, and getting addicted again. As an addiction, this beats smoking....

[Cody]

Oh yes indeed!

[Smivs]

Can't stop either one!
Congrats on the release...looks really nice.

[Kaks]

Very nice! And I can finally see the screenshots too!
(For some weird reason I can't see anything hosted on i56.tinypic.com)

One thing though: could you put the readme (and the screenshots directory) just outside the .oxp directory? Mac people won't even know they're there otherwise!

No problemo, Kaks. Duly noted, wildo that next time I realease something.

NPC ships don't have the alertCondition property (only player ships have it) so the pirate version doesn't get spawned.

To this end I have come up with this work-around...

Could probably do with some better logic.

[Thargoid]

Just for completeness, stations also have alertLevel (but you are correct that NPC ships don't).

Interesting work-around though, including a couple of bindings that I didn't know about.

[Commander McLane]

However, you seem to use an editor that makes garbage out of plists. All these '+' and '-' characters and '---' and '+++' and '@@' lines don't belong in there.

The result is an invalid shipdata.plist that's getting rejected wholesale by Oolite. Thus, no ship at all will appear.

[another_commander]

However, you seem to use an editor that makes garbage out of plists. All these '+' and '-' characters and '---' and '+++' and '@@' lines don't belong in there.

That's a diff file, not a plist. It's used as input by the patch program for patching files.

[Tricky]

Sorry, forgot to mention that it was a diff file used by patch.

Here is an update zip file https://www.box.com/s/f3fb2bd7bb7201aa84c1

It just contains the Shaders directory and the shipdata.plist file. Just place those in the original OXP directory.
