[RELEASED] uConstruct - Fully generic, socket based runtime construction system

Awesome bro! Also do you have any plans to integrate Opsive's Third Person Controller or Invector's Third Person Melee Template? If not how and where should I start in order to integrate it on my own?

 

Yes its on the milestones but not sure when it will be implemented.


And well, it shouldnt be to hard, i guess just add the damage interface of their system to the building component or call damage directly from the scripts, w/e works for you

 

Can i use this asset to build dragable walls (similar to rimworld but 3d)?

 

If it involves building, it will work with uConstruct

 

Made something similar to that once, very easy

Just a bit of coding needed, but its indeed functional .

 

cool! do I need to use it in 1st person, or can it be use more as 3rd?

 

W/e you prefer

 

Do u have any docs about implementing uConstruct with 3rd party person?

 

Well its very easy , just on the BuildingPlacer component select the raycast origin to be Mouse Position and that's pretty much as far as it goes, everything else is automatic .

 

There is much more to do than just this.. the rotation and movement aren't sync with the

In the demo scene, i used the BuildingPlacer component on the third party controller from the unity standard asset (raycast origin to Mouse Position)and for some reasons, the input 1 to 9 werent working anymore. The UI was also not displaying the controls.

 

Did you get any errors ?
Also enable "Rotate with player" if you want rotation as well

 

I was not getting any errors. Very strange.

The UI (with the controls) was not displaying, and the input was not working. I could walk around, but not build any foundation or walls.

 

Could you verify that the controller's buildingPlacer that you are using has buildings attached to it ? (You can copy the demo's one for testing)

 

How to solve these 2 problems?

 

Sorry for that, was reported to me earlier today, will push an hotfix soon.


For now replace Photon.ReceiverGroup with simply ReceiverGroup (no namespace).


Sorry!

 

Hey, I'm back! (I started working with uConstruct back in January/February but then more pressing projects turned into 8 months of crunch...)

Elroy, you're astonishingly active and have remained pleasant, enthusiastic, encouraging and humble all at once. You're super-human. This is an amazing asset too!

My question: generating buildings with sockets and conditions at runtime? I will be generating custom meshes (such as arch voussoirs) based on user-defined parameters at runtime and I'd like to know how I might go about setting up all the sockets after I generate the mesh.

This will have to be done through the API, and I know that Elroy put this ability in there back in February in response to my request, I just don't know where to find it now.

Thanks!

 

Hey!

Thank you very much for the kind words!


Well, the way you could do it is let them design it like a gameobject and then add it as a socket (building.AddSocket/ AddCondition)

You could use "CreateSocket" and "CreateCondition" to generate them from the system and they will be created immediately and you only need to let the players move them. (I recommend the second method)

 

That seems to work (I used the CreateSocket method you suggested). I've got a basic building (a cube) created entirely in code and handed off to the building placer for placement. I just create a cube, add the BaseBuilding component (configure it) then start creating and configuring sockets.

Question: Is creating a building entirely at runtime - without it having been a prefab at first - going to cause trouble for the Building Batching system or AoI or saving?

I'm sure I'll have more questions as I dig deeper, but for a start, this is encouraging. Thanks!

 

Happy to hear that it works !

And yep :/ multiplayer and savimg wont work but you can easily change that by modifying the build system and usr path instead of id

 

Could you be a bit more specific about how to modify the build system and usr path, please? Not sure I understand what you mean.

Thanks again!

 

Considering you are loading items from an external folder and not a building from the project itself you must save the path to the object instead of the ID.

Lmk ifits still not underdtandable,
Once it is i will give you some tips on extending the save system

 

Hey, thanks for the guidance - it makes sense - and sorry for the delayed response.

I'm building meshes in code at runtime - so, not loading them from an external folder. Is there some way to update the prefabDB at runtime so that these new meshs/GameObjects can them become 'normal' uConstruct buildings?

I have EasySave, so, as long as I can save the runtime-built meshes and their uConstruct setup in there and reload them, I'm okay. I'm sure I can find a way to achieve what needs to be done.

Another question: I'm trying to replace the meshes on certain uConstruct buildings that pre-exist as prefabs. How can I replace the mesh in individual, placed uConstruct buildings?

Example: I have a brick that is a uConstruct prefab. I run a boolean mesh operation on this brick in order to cut off a piece to make it fit in an awkward space. ​

When I try this, I can create the new brick mesh and assign it to the mesh filter of the uConstruct brick - but the new mesh does not display in the scene view - even though the editor confirms it's there in the placed uConstruct brick MeshFilter. Any suggestions?

As ever, many thanks!

 

Uhm about the prefab id i'd say give it a shot and if it won't go well i will try to implement something like that


For replacing a mesh you must first disable the batching of the building (building.batchBuilding = false) and then replace the mesh and re-enable the batching (building.batchBuilding = true)

 

Hi Elroy, I'm wondering if you can help me. I'm trying to add so I can destroy a building part with a weapon and repair with another, I've managed to make that part work but I need to destroy the building part in my Die function.

I'm just not sure how to reference it.

Hey! I think I'm now able to add my runtime-created buildings to the PrefabDB at runtime. Since your PrefabDB doesn't strictly rely on prefabs (the creation of which are strictly editor-only), I've been able to to add my own objects upon creation in the player. I haven't tested this with a stand-alone player yet.

Still working on swapping meshes. It doesn't seem as simple as just turning off batching, swapping out the mesh, then turning batching back on. But this may be due to the CSG library I'm using too. Will keep at it and report back.

Thanks again.

 

Happy you got it fixed, sorry for being a ghost today, wasn't home at all.

Happy you got thje prefab db fixed .

Lmk what else you found about it, i personally use that method in a different project for material and mesh switching and it seems to work perfectly

Keep me updated!

 

I haven't tested out my runtime DB update in a build yet. Will let you know how that goes, but it will be a while before I get that far.

I have gotten the mesh swapping to work! It was the mesh boolean library I was using - it based the boolean mesh on world 0, so the mesh appeared very far away from the uConstruct building. Fixed that and it works fine now - there was nothing wrong with your code, just my understanding of my boolean library.

Many thanks!

 

Today's question: Custom condition and BaseBuilding null reference

When placing a building on a floor object - the 'ground' in the scene - it is always placed sunken up to its pivot in that floor object.

To prevent this, I've written my own condition (cribbed from your CheckForCollisions condition) which checks during placing if the building is in contact with the floor object. If it is, it sets the building's placingOffset.y to half the height of the bounding box of the building. If it is not in contact with the floor object, it sets the placingOffset.y to 0. In my code, I have to refer to BaseBuilding.placingOffset twice in an if/else statement.

When I run the scene in the editor I always get a null reference error pointing to the line where I make the second reference to BaseBuilding.placingOffset (in the code below, line 44). If I have just one reference to BaseBuilding.placingOffset in the script, I don't get that error, but then I can't toggle between zero offset and each building's specific offset.

Below is my code - any thoughts? Perhaps there's a simpler way to do this.

Thanks, as ever, for your help - and do PM me if I'm taking too much of your time/being a pest.

Never heard about that one, but you can try changing that:

4.                 baseBuilding.placingOffset.y = offsetHeight;
5.                 offsetSet = true;
6.             }
7.             else {
8.                 baseBuilding.placingOffset.y = 0.0f;
9.                 offsetSet = false;
10.             }
11.         }
12.  

with

Code (csharp):

1.  
2.       public void SetOffset () {
3.            bool isGroundCollider = collisions.Contains(groundCollider);
4.  
5.             if (isGroundCollider) {
6.                 baseBuilding.placingOffset.y = offsetHeight;
7.                 offsetSet = true;
8.             }
9.             else {
10.                 baseBuilding.placingOffset.y = 0.0f;
11.                 offsetSet = false;
12.             }
13.  
14.             baseBuilding.placingOffset.y = isGroundCollider ? offsetHeight : 0.0f;
15.         }
16.  

And it is always my pleasure to help .

 

Your code is much more elegant than mine but it didn't get rid of the error.

However, it did make me dig a little deeper and I discovered that the condition was being checked before all of the references were set. I changed that and it works like a charm!

I think I've got a pretty good grasp of uConstruct and what I'd like to achieve with it at this point. I'm sure I'll have questions in the future, but for now everything is going well and I'm turning my attention to UI and splines (fun!).

Thanks tremendously for your help.

 

Happy you got it working .

 

Hi Elroy! I'm just wondering about when rotating a building object...
When I placed it snaps to 90 degree, but if I rotate the object before plcing it doen't snap to 90 degree its at like 86 degree...

I'm not sure if its a Unity bug as recently it sets the rotation to some objects off 90 degree...

I'm using latest UConstruct and Unity 5.4.1 Win 10

Thank You if you can Help!

[/IMG]

The stairs on the right are just placed with no rotate with mouse wheel, and the one on left is rotated with mouse wheel

 

First of all, beautiful structurs

And very weird, havent experienced it so far but i will check it first thing when i am home !

 

XD I made them today some Stone parts

and THANK YOU SIR!

 

Just done some testing, it happens if I have rotate with player on the Inventory Building placer, if this is unchecked then it rotated perfect.

Hope this helps!
Thank You

 

Oh ofcourse, that's a feature, its basically rotating the building according to the player rotation

 

Oh I mean if I have rotate with player on and place a foundation, when I place a stairs and rotate before I place then it doesn't snap to 90 degree...

But if I have rotate with player off and place a foundation then place a stairs, but before i can rotate and it snaps to the foundation 90 degree....

But with rotate with player because the foundation isn't placed on a 90 degree to world the stairs is acting like its snapping to the world 90 degree and not the foundation its placed on then 90 degree...

Not sure how to explain

 

uhmm, if possible, send me a private msg with your skype and i will try to adress it privately tomorrow, will be easier

 

Hey guys!

Wont be online for the next 25 hours as part of an tradition! sorry guys!, no support until i am back, as i cannot use the computer at all.

Please do not worry if i am not answering until i am back .

 

How to disable the save blocks on the card? in the options there is 2 lines and the inclusion of conservation. I clean there is 2 ticks . Start the game and put the blocks where the checkboxes are automatically enabled!! The next time you run these units back on the map. how to make so that the blocks were not saved?

 

Wait, you mean that disabling the saving on the settings doesnt work ?

 

Yes , every time I turn off the save mode and every time I go to the map and there is an old building.

 

Thanks for the report, will check it before the flight today

 

Hey alex i am going out on a vacation now, didn't have the time to look at it, i am so sorry...
I will be back on the 24th, and then i will send you a fix.

What i recommend to do now is go into the code and basically make UCSavingManager.enabled = false;
(On the building placer before it loades the save)

Sorry for the hardcoded solution.

I will try to be as active as possible on support and forums

 

Hey @ElroyUnity is it possible to remove uConstruct's saving system and use our own?

 

Yes,
you will need to disable the saving system from the settings, Alex reported that its broken though, i will look at it on the weekend .

 

Okay cool seriously having to restrain myself from going and buying it before I've made the necessary changes to our project

 

Ugh the delay in forum posts getting through - I wish Unity's forum was able to sent notifications through Chrome... (best browser )
