Anyone who can tell me where I can post my recvest about making tcg/trading card battle ?

Design is easy, but scripting to help the game is hard.
I try to get rotating the card, but it will not work what ever I do.

Anyone who can collaborate with me ?

 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[ExecuteInEditMode]

//0 referance

public class Card : MonoBehaviour
{
public RectTransform cardFront;
public RectTransform cardBack;
public Transform targetFacePoint;
public Collider col;

private bool showingBack = false;


private void Update()
{
RaycastHit[] hits;
hits = Physics.RaycastAll(origin: Camera.main.transform.position + targetFacePoint.position,
direction: (-Camera.main.transform.position + targetFacePoint.position).normalized,
maxDistance: (-Camera.main.transform.position + targetFacePoint.position).magnitude);

bool passedThroughTargetCollider = false;

foreach (RaycastHit h in hits)
{
if (h.collider == col)
{
passedThroughTargetCollider = true;
}

if (passedThroughTargetCollider != showingBack)
{
showingBack = passedThroughTargetCollider;
if (showingBack)
{
cardFront.gameObject.SetActive(false);
cardBack.gameObject.SetActive(true);
}
else
{
cardFront.gameObject.SetActive(true);
cardBack.gameObject.SetActive(false);
}
}
}
}
}


I hope someone can help me to figure out what the problem I having here.

 

maybe try to check if there is something in the array.

Thank you for answering my post.
You have to help me out here.
How do I check if there is something in the array.
What is wrong with the array ?
Shoul it be something in the array ?

Maybe something like this: private void Update(ref int i) ??
Or RaycastHit[ref int i] hits; ??

No wonder I having big problem to find it out.

 

line 28 in the edited script, still I am not sure if this will help

 

I hope you can see this picture.

 

Look at the script that I have posted. For array-check you can compare it with null

1. if (hits != null)
2. {
3. foreach (RaycastHit h in hits)

 

and if you will make just card rotation then maybe use 3d card. You can rotate it as you will.

 

I try to make a Trading card battle with face down.
You pick a card and you can see an avatar do battle.
Card it self not importen to have a 3d, only 2d.
Battle is in 3d.

I try to upload som picture but am not sure I got it right to show you.
For that am sorry.

I made a video recording but it was to big for forum.

If you go to twitch under Henmart and find a clip called "Testing" you can see the recording of it.

 

Look at the script that I have posted. For array-check you can compare it with null
#D Game looks like this, I hope.

1. if (hits != null)
2. {
3. foreach (RaycastHit h in hits)

[/QUOTE]
Ok, but what will I put in instead for h ??



Ok, I change it to this:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[ExecuteInEditMode]
public class Card : MonoBehaviour
{
public RectTransform cardFront;
public RectTransform cardBack;
public Transform targetFacePoint;
public Collider col;

private bool showingBack = false;

private void Update()
{
RaycastHit[] hits;
hits = Physics.RaycastAll(origin: Camera.main.transform.position + targetFacePoint.position,
direction: (-Camera.main.transform.position + targetFacePoint.position).normalized,
maxDistance: (-Camera.main.transform.position + targetFacePoint.position).magnitude);

bool passedThroughTargetCollider = false;


if (hits != null)
{
{
passedThroughTargetCollider = true;
}

if (passedThroughTargetCollider != showingBack)
{
showingBack = passedThroughTargetCollider;
if (showingBack)
{
cardFront.gameObject.SetActive(false);
cardBack.gameObject.SetActive(true);
}
else
{
cardFront.gameObject.SetActive(true);
cardBack.gameObject.SetActive(false);
}
}

}
}
}


But still the card back not showing up.
But now the spell card body is now in highlighting in yellow.





Edit:
Not even this worked:
if (hits != null)
{
showingBack = passedThroughTargetCollider;
if (showingBack)
{
cardFront.gameObject.SetActive(false);
cardBack.gameObject.SetActive(true);
}
else
{
cardFront.gameObject.SetActive(true);
cardBack.gameObject.SetActive(false);
}
}




Edit 2:

hits = Physics.RaycastAll(origin: Camera.main.transform.position + targetFacePoint.position,

object reference not set to an instance of an object.

Loks I have a poblem with this ??

 

try to do something with this,

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Card : MonoBehaviour
6. {
7.     public RectTransform cardFront;
8.     public RectTransform cardBack;
9.     public bool showingBack = false;
10.     Collider col;
11.     bool canRotate = false, canRotateBack = false;
12.     public float rotateSpeed;
13.  
14.     void Start ()
15.     {
16.         col = GetComponent<Collider>();
17.     }
18.  
19.     private void Update()
20.     {
21.         if (Input.GetMouseButtonDown(0) && !canRotate && !canRotateBack)
22.         {
23.             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
24.             RaycastHit[] hit = Physics.RaycastAll(ray);
25.             if (hit != null)
26.             {
27.                 foreach (RaycastHit h in hit)
28.                 {
29.                     if (h.collider == col)
30.                     {
31.                         CardRotate();
32.                     }
33.                 }
34.             }
35.         }
36.  
37.         if (canRotate)
38.         {
39.             transform.Rotate (Vector3.up * rotateSpeed * Time.deltaTime);
40.             if (UnityEditor.TransformUtils.GetInspectorRotation (transform).y >= 90)
41.             {
42.                 transform.eulerAngles = Vector3.up * 90;
43.                 canRotate = false;
44.                 showingBack = !showingBack;
45.                 if (showingBack)
46.                 {
47.                     cardFront.gameObject.SetActive(false);
48.                     cardBack.gameObject.SetActive(true);
49.                 } else
50.                 {
51.                     cardFront.gameObject.SetActive(true);
52.                     cardBack.gameObject.SetActive(false);
53.                 }
54.                 canRotateBack = true;
55.             }
56.         }
57.  
58.         if (canRotateBack)
59.         {
60.             transform.Rotate(Vector3.up * -rotateSpeed * Time.deltaTime);
61.             if (UnityEditor.TransformUtils.GetInspectorRotation(transform).y <= 0)
62.             {
63.                 transform.eulerAngles = Vector3.zero;
64.                 canRotateBack = false;
65.             }
66.         }
67.     }
68.  
69.     void CardRotate ()
70.     {
71.         canRotate = true;
72.     }
73. }

but I would say, use 3d card for rotate

 

Thanks.
is there a 3d templates of card ?
I guess you have o buy it ??

 

you can find the free royality 3d card in google. Or make it with one 3d program. The simple card is just one flat box.

you can try this fbx file, this is the perfect work from me in blender Sorry i am not making 3d games and this is awful.
http://xrayisgray.de/packages/Card.fbx
then import this .fbx file in unity, create new material (right click in assets), add your card image to this material (left from "Albedo" is the select point, or switch material to unlite/texture and add the image to it). Then add this material to the card prefab (the card have 3 materials: border, back and front, just change the needed).

 

Thanks am gonna try it.

and this is what I got.

 

try to change: element 0 - border (you can leave it as black, it is just the side from the card), element 1 - back, element 2 - front.

And you should change the script now, no need for rect transform, if the card is 3d.

maybe this

sorry, I just don't know what the type of rotating you are needing

if you don't like 20000 scale, you can select imported card, go to model tab and change scale factor (don't forget to reset the collider on the prefab in this case).

 

It's working now, execpt for picture face.
I have no idea how to fix that.

Order in layer or/and additional shader, or/and blocking object, blocking mask, or/and sorting layer ?
I hope you can help me.

 

try to put your "Back" material in all 3 slots. If the problem stays then I have did something wrong with normals (reverted face).
you can try this other card

I thank you for contribution yours, but I think it over and it's not necessary to have it.
