[RELEASED] Truss Physics for Unity3D. Soft-body simulation plugin.

Why do you just ignore me? I bought asset, ask red car demo source via email, PM, this thread, but you just can not give me a link? Seriously?

 

Thanks ASDev
what do you mean 'edge'?
"external node of the wheel connected to EDGE"
ive tried a few times to get wheels working without success.

also, are you using softbody tires, if so could i see how you set them up please?
all i can get is kind of balloons whatever i try

that Red Car source would be handy but doesnt seem like Heartbroken is willing to give it out

 

can you share this to me?

Hi Yes Check in Gmail

 

Truss constraint has 2 type of connections. To node, and to edge. Node - 1 point (node), edge - 2 nodes.

 

Give me a RedCar demo pls.

Are you still developing Truss Physics?

 

Hi all, recently TmSonicX(I'm not wrong with the name?) sent me a generated demo of RedCar. And I fixed the bugs, moved it to a new, 1.0.4, version of Truss Physics. But not everything is so perfect, maybe only me, but when you exit the runtime - Unity is crash. I don't know what the problem is. The project was rebuilt on Unity version 2018.2.2f1.

Enjoy This Thanks for Uploading i use Special Software for Generating Games only for Unity 3D Contact me for Generating other Games

none of those rar files will open.
i couldnt get TmSonicX's version to work at all.
every attempt at making my own from scratch is fraught with constant crashes.

shame truss has been abandoned because its potential is massive

 

What do you mean, tegleg?

 

they all say
"unable to open archive"

 

Use this demo for understanding of Truss constraints and truss bodies. And use it knowlege in free version of truss physics, it's stable

 

ASDev, i think that the problem of Unity crashing - is a RedCar script.

 

Tegleg, try this one:

that one opens thanks NotGoodEnough

ASDev, i agree redcar is something to learn from, to pull apart and see how it works.

EDIT:
OnDestroy() in redcar script was causing a crash because it was looking for txworld but it did not exist.
a quick fix is,
change

Code (CSharp):

1. private void OnDestroy()
2.     {
3.             TxWorld.instance.onBeforeStep -= UpdateCar;
4.     }

to

Code (CSharp):

1. private void OnDestroy()
2.     {
3.         if (TxWorld.instance)
4.         {
5.             TxWorld.instance.onBeforeStep -= UpdateCar;
6.         }
7.        
8.     }

 

Tegleg, good job

 

Guys, how do you like the idea to rewrite the runtime part on ECS?

 

Who knows the easiest way to make Truss for models?

 

There is no easy way. I create trusses manualy with nodes. edges and fases. It's take a lot of time. Maybe some 3D editors has plugins for creating meshes like trusses

 

ASDev, What about modeling a Truss model using a primitive? For example, create a cube and make it the most simplified model shape? How's that for an option? I did it for the wheel, took the cylinder and customized for the model. It went well.

 

What about that "https://github.com/wjakob/instant-meshes"?
Video about it "

"

 

If you speak russian I can explain how I create truss bodies. My english is not very good )))

 

ASDev, yes I know Russian language.

 

Is Fixed Unity running still Nice

 

I will be updating this RedCar, although the fix is not completely perfect as in the original, but perhaps it will work

 

the fix i posted above only seems to work sometimes. i havnt delved into it any further.
for my own tests i added this to Test002.cs at the end of Update()

Code (CSharp):

1. if (Input.GetKeyDown(KeyCode.X))
2.         {
3.             UnityEngine.Object.Destroy(carInstance.gameObject);
4.         }

so before i stop it i press X to destroy the car, then it does not crash unity.

now i have something (redcar) to actually play around with truss physics its looking more and more like it could do with an overhaul to stop all those crashes and inconsistencies.
i still have pretty much constant crashes every time i try to edit nodes on a truss model.

 

Can you upload RedCar Project on my Gmail ? Facerougex@gmail.com

 

What do you think, is it possible to somehow optimize the work with Truss Designer, for example, while editing Links, especially when a lot of Links, lags editor. I also noticed some crashes during copy-paste of TxConstraint components from one object to another.

 

ive integrated into a large project ive had lying around since unity 5.3 so sorry i cant upload it.
the truss part is NotGoodEnough's download with the fixes i posted.

i get a lot of crashes editing truss.
it can definitely be optimized and improved but the best person for that would be Heartbroken, he seems to have lost interest in truss unfortunately.

 

Yes, but power is in the community! We were able to restore the RedCar Demo project, Yes with errors, but it works. Is it really more difficult to optimize this code?

 

What about that problem on runtime start?

 

i dont get those or any errors on runtime start. im using unity 2018.2.2f1

the problem with the community trying to improve it, or even work with it properly, is there is little to no documentation and absolute zero comments in the code. its a massive undertaking going into something this complex totally blind.

edit:
the attached zip contains documentation for truss and redcar generated from doxygen.
(open index.html)

 

Ok Thanks

 

if i buy this asset do i get the source to the .dll's?
now i can see how to actually use this asset thanks to TmSonicX, NotGoodEnough and whoever made RedCar Demo, as a programmer it would be very useful to see exactly what im dealing with.
thanks

 

You know, I don't see the point in paying if the project is dead, why wouldn't the developer just lay out the source code of the project so that the community could continue to keep the project up-to-date.

 

Good Evening all,

i have downloaded the Red Car Demo from NotGoodEnough Thank you very much this was the only reason i did not buy the script in the end as this demo source was not given or even asking for it there was no mention of me getting it and the only reason to buy it was for damaging cars.....

Now i have it loaded in 2017.3 but i can not drag the RedCar Prefab into any scene so i can edit the nodes, links or faces....

How do i go about doing that?

i drag it over the scene and i get the no entry sign... i try and drop it on the Hierarchy and it does not go in (does nothing)

Thank you for your time

TADS

 

Try this link:

 

Thank you for your reply NotGoodEnough but i said i did download it thank you for the link but i am unable to drag the prefab into the scene to edit the nodes etc....

 

I understand that you downloaded and can't drag and drop prefab. I just thought maybe the archive was broken.

 

i see what you are saying.
there are a couple of problems with that though,
i am making a commercial game with truss so i need the license,
there is an advantage to having the source of the .dll's from a code standpoint, optimizing, fixing the editor bugs, and expanding truss.

@tads421
maybe try unity 2018?

 

Hello everyone,

I've attempted to fix the RedCar prefab. After downloading the prefab below you should be able to drag/drop the RedCar prefab into your scene and edit it's nodes.

Hi,

does anyone knows if Heartbroken is still following this thread?
If not this is a pity, because this physics has an incredible potential.
some step by step video tutorial (even without audio) within unity on how to create stuff would be enough to make people to understand.

 

One more video with Truss Physics. Realistic tires

 

Pls make tutorial this
Thanks

 

It's a little complicated and hard to explain and to uderstand. If you don't understand the idea of truss physics nodes, links and faces - I'm afraid I can't explain this. If you can create stable truss body and you don't know how to add wheels - I'll try to explain

 

I use TrussPhysics but i do not know where is the error but it would be good some short videootutorial how to create nodes try but not see

 

There are no errors. Download blank Truss Physics, not redcar demo from this topic. And try to setup truss body and wheels

 

I don't know how :/ Help me

 

Truss Physics has truss primitives in examples. You can use box primitive to create truss for car body

 

That's what I did, but the deformation is wrong, it's not like RedCar's where the bug is
