Batman Tumbler

Thanks to guicam for improved physics script.
Thanks to cameni for the Fixed script.
The model was converted from thefree3dmodels.com

Installation:
Folder from the archive to put in ..\Outerra Anteworld\packages\outerra


File :
Google Drive

Author: Stopub (Unsurt)

Wow, nice :-)

Hello,
the picture looks GREAT!!!
Greetings,
Edwin

[Foxiol]

Okay, now that is cool. I like Batman (comics, cartoons, movies, games)...Outerra + Batman = Total win!

Thank you!

EDIT: The quality of the model is superb! Great job!

Fixed script so that you can spawn more than one. The problem is that 'this' only refers to one vehicle, so any chassis parameters must be stored globally.

[ZeosPantera]

Its OK cameni, I will probably spend hours tweaking that beast to drive like in my dreams. Now how would one go about making it boost jump across rivers and rooftops?!

[Chaoz]

custom keymapping and events in scripts would be awesome to implement those features

Now only a cockpit view is missing to complete its awesomeness

[deathevor]

Request to Cameni:

The thumbnails for vehicles are stored in Outerra\Anteworld\www\images\pkg at the moment.
So most of people forget about them. Ang currently it is tootal mess in vehicle list.

I know the vehicle installers will solve this, but still would be nice to keep everything (thumbnails and preferably even Plane Engine scripts, flightmodel scripts) in the model folder (or sub-folder).

This would make it much easier and cleaner to backup whole lot of current (installed) vehicles.
As well as sharing them.
And basically the installers won't be needed so much.

Yeah, i forgot to tweek the cockpit view. Too eager to share

Tank you, i have integrated your script in the shared file.

Hello Unsurt,
is it possible that you can integrate such an realistic physics to the Tumbler Car like in this Unity3D-Game:

Working on it.. My only issue is she likes to flip (literally) out when going into the rocks in the terrain.

Please put such feature requests into the tracker. Nobody will find or remember it when it's located somewhere on the forums, especially not if it's like here in the middle of a completely unrelated thread. Or at least make a separate thread in the support board, but the tracker is a better place for this.

I think the next step is object ramps we can leap off of. Not sure when collisions will be ready.
