Hi, I have recently purchased this fantastic asset but I have now bumped into a small problem : Raycasting.
Do you provide some raycast extension / math to convert raycast point to curved point?

I need the correct representation of the rendered coordinate.

Edit: And I do understand that the shader only handles the rendering, so the mesh collider is still the normal shape, thus the raycast "fails". I still hope you have a suggestion for a solution

 

Curved World API has function for converting real world Vector3 point into 'bend version'.
TransformPoint() - Check API.pdf file inside doc folder.
Also check example scene - '3. Little Planet: Deferred Rendering, Physics and NavMesh' - there is usage of that function for updating physics colliders and point lights position.

Thanks, I tried using TransformPosition now, but it doesn't work as intended. I tried writing out the values, and there seems to only be a change in the Y component:

My camera is located at approx: 250 Y (depending on terrain), so that fits.
Pivot point : (0.6, 250.4, 0.5)
However as you can see, it only changes the Y component, which is really the only part I wouldn't expect to change.
Hit point : (62.6, 45.7, -26.2), Curved world transform point : (62.6, 27.4, -26.2)

So based on this, I think I'm using the TransformPoint wrong or it can't be used for raycasting purposes.

Are you suggesting that I instead move the y-position of the collider? (In the demo scene, the light is moved, which I can't really see a way to apply to raycasting logic). Edit: I dont even think its possible to offset a terrain collider :/

 

Seems you are using it wrong way, but I can not help, because it's your code and logic and you better know what you are doing (or want to achieve).
All the TransformPoint() function does - convert world's Vector3 point into Curved World 'bend version'.
You can transform just one point (pivot point of object or center of mass, or what ever you want) or iterate through all mesh vertices and bend it using script on CPU instead of using shader.

Okay, it was worth a shot. Thanks anyway

I guess I'll try to dig into the shaders and attempt to write my own Raycast extension that works similarly (but opposite) of the TransformPoint method.

 

Better transform position of collider and then use normal(original) Raycast.
That's why I suggested to have a look at - 3. Little Planet: Deferred Rendering, Physics and NavMesh - colliders positions there are updated to reflect Curved World's transformation and normal Raycast can be used on them without problem.

Transforming the collider doesn't help. I tried transforming the collider and doing a new raycast but that doesnt do any good. It really only moves my raycast closer to the ground.
I've tried drawing it, but I don't know how else to explain it.

 

Hi,
I don't know where to post this, as the Curved World 1 threads are closed, I realise that Curved World 2 is what is officially supporting Unity 5, but I thought someone might know a workaround for a bug with Unity we're experiencing.

We're using Curved World 1 in Unity 5, and the shader works fine on the whole, except it doesn't compile on Adreno 320 Android devices (Samsung S5, Xperia Z2).
This looks to us like a bug with Unity, and I have filed an issue (744987) but with a release date looming, I thought it'd be worth checking here in-case there is a workaround.

The compiled shader code when view in the Unity Editor is attached

The error from the device logs when ran on Adreno 320 devices is:
ERROR: 0:152: 'assign' : cannot convert from '2-component vector of float' to '4-component vector of float'

Problem line in generated shader code:
vs_TEXCOORD1 = phase0_Output0_2.x;

where the variables are:
out mediump float vs_TEXCOORD1;
mediump vec4 phase0_Output0_2;

Sorry if there is a better place to post this!

 

What's the shader name and what optional parameters are checked ON?

Hi, I am trying to write a script to access the API and change the Bend variables at runtime. I can't seem to get the namespace to work for me, but it could be that I don't really know how to access namespaces properly? Can't seem to access SetBend or the public bend variables. Do you have any example scripts to modify the vars at runtime?

 

Code (CSharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. using VacuumShaders.CurvedWorld;    //!!!
6.  
7. public class NewBehaviourScript : MonoBehaviour
8. {
9.  
10.     public float xAxisBendSize;
11.     public float yAxisBendSize;
12.  
13.  
14.     void Update ()
15.     {
16.         //Getting reference to the existing in the scene CurvedWorld_Controller script.
17.         if (CurvedWorld_Controller.get != null)
18.         {
19.             CurvedWorld_Controller.get._V_CW_Bend_X = xAxisBendSize;
20.             CurvedWorld_Controller.get._V_CW_Bend_Y = yAxisBendSize;
21.         }
22.     }
23. }
24.

Was missing the .get. ! Gracias! I am too used to Unity namespaces I think. This is a very cool asset!

 

Hi. This looks a top quality product so I have bought it, even if there is a chance it can't fit my current needs.

I want to create a tower climbing game, but the intricacies of building levels around a tower are horrific for quick level design. I was hoping to use this shader in the Perspective 2D mode to wrap a plane with obstacles placed on a grid around a tower.

However I want to be able to run all the way around the tower and for it to seamlessly then move from one side of the 2d plane to the other. Similar to the old Amiga game Nebulous (I also would like tunnels through the tower which is a harder problem).

Is there anyway I could use this asset to perform that function for me in either its current form or in a modified form? Then I could just design my levels in 2D on a grid, click Play and it would then build the tower for me? Ideally you should set the world points or size at which it joins the ends of the plane together.

PS I also posted this question on your Facebook page earlier today.

Thanks

 

Curved World creates never ending curvature effect. It can not convert plane to sphere or cylinder where you can rotate on orbit on 360 degree and return to starting point.
As for Nebulous game, I think it does not need any special shaders, it can be achieved with script rotating 'world' while character always stays in the camera center.

That's a great idea. That will work. Thanks for the suggestion.

 

I have another question.... I need my player to be able to climb the tower. However when I extend the sample scene grid to double the height, the view on screen cuts off the top and bottom so you only see 16 rows of the grid no matter how tall it is.

Is there a way to adapt the shader or settings so it extends off the top and bottom of the screen?

 

Use Unity 5.2.2p2 and EagleEye script on active camera. Meshes that go beyond camera view frustum are culled before Curved World bends them. EagleEye script will fix it.




VacuumShaders - Facebook Twitter YouTube

 

I am doing that. I am just using your example perspective 2d scene. I have copied the top two rows of your grid and pasted it multiple times above, so it is now twice the height. The Game View still shows a hard cull at the top and bottom after 16 grid spaces.

I have attached a screenshot for example:

 

Do not confirm. At my side everything works as supposed.
Use Unity 5.2.2p2
In earlier versions EagleEye script does not work and some objects may disappear.




VacuumShaders - Facebook Twitter YouTube

 

Ok. I am on 5.2.0f3. Does your component work with the latest 4.3 beta?

 

Problem is not in my component, but Unity itself. In earlier version there is bug, that Unity fixed in 5.2.2p2: http://issuetracker.unity3d.com/iss...erender-fov-change-regression-since-5-dot-1-3



VacuumShaders - Facebook Twitter YouTube

 

Thanks. I did of course mean the latest 5.3 beta (f1). I've tested and it works fine in that beta and in 5.2.3.

 

Is there any way at all this could be done without shifting all the tiles but just moving the player? Reason I ask is it makes for much worse performance that way. I've quite a few games where I keep the camera and player still and move everything else and it always creates its own problems.

 

It depends on your game design. You know better. All I can help is with Curved World.

If particles are not rendered correctly in Unity 5.3, disable Use With Particle System option inside material editor.

Are Lightmaps supported in snenes with Surved world?

 

Yes.



VacuumShaders - Facebook Twitter YouTube

 

Can you curve this?
https://www.assetstore.unity3d.com/en/#!/content/50771
its an instantiated object that creates a road

 

Curved World is shader. Apply it to any mesh and it will be bend.



VacuumShaders - Facebook Twitter YouTube

 

I was able to get this working pretty quickly but I'm not seeing the Curved World options in preferences. Is there a step that I need to take to make those option show up? I have classic runner set as default in the "Curved World_Controller" script and the drop down it is greyed out. I'm using Unity 5.3.0f4 Personal

Hi,

Is it possible to use the Toon Shader Basic / Outline ?

Thanks.

 

Package includes toon outline/ramp shaders.



VacuumShaders - Facebook Twitter YouTube

 

Hi,

Thanks for your quick answer!

It's not the same effect as Toon Basic / Outline.

I will do a custom shader

Thanks!

I Have another question : I have a lot of error :
IsFinite(outDistanceForSort)
UnityEditor.DockArea:OnGUI()

What can I do for this?

Thanks a lot.

Best regards,
AB

 

With error messages Unity prints in console function names where error occurs. Can you provide more info, 'IsFinite(outDistanceForSort)' alone tells nothing.



VacuumShaders - Facebook Twitter YouTube

 

I would have liked but I just have this messages.

 

I have this too some times :

IsFinite(outDistanceAlongView)
UnityEditor.DockArea:OnGUI()


Thanks a lot

 

Not enough info, I even can not identify it as Curved World bug.



VacuumShaders - Facebook Twitter YouTube

 

Totally understand that. But how can I provide you more info?

Thanks a lot.

(I'm on Unity 5.3.1)

 

Select error and Unity will display more info about it (function name and error reason).




VacuumShaders - Facebook Twitter YouTube

 

I did't send you this because is useless in this case :

 

I have just updated Unity 5.3.1f1 and found no problem. Also your warnings do not show any references to the Curved World, so I can not help.

Ok,

Thanks for trying !

 

OK it's happening on Unity 5.3.1 with Particle (using your shader) for your info.

 

Hi,

hey,
is there a way to adjust also a box collider according to the curved object?

it somehow always floating in the air which makes clicking on it pretty difficult

 

Thank you for the quick response to my previous question.

Question about Mobile. I replaced the Mobile>Diffuse (with diffuse map) shader that I was using with VacuumShaders > Curved World > U5 Standard > Standard. The map is put into the Albedo slot and this looks OK. However, I lose 10-20 frames per second (testing on iPhone 6 Plus) even when I am not doing any world curving. Is there a better shader option for replacing mobile/diffuse that includes the map slot?

Thanks!

 

You can transform all points of collider using - TransformPoint() - check API.pdf in Doc folder.

Use One Directional Light shaders.
