Seamless Teleporting

Hello Guys,

I'm looking for a good solution for my seamless teleport.
V3 is actually the only one that is looking seemless with collision detection on both sides. But its completly inefficient (1 Character = 3 Character).

This is just an example, CharacterGameObjects from my Game have alot of Childs full of Scripts and Colliders and Triggers. Its also an Multiplayergame for Mobile devices so 4 Player with Teleport v3 will result in (4*3=) 12 Character calculations.

Is there another way of implementing a seamless teleporting?

Teleport V1 (OnTrigger)

Code (CSharp):

1. public class TeleportScript : MonoBehaviour {
2.    
3.     void OnTriggerEnter2D(Collider2D other)
4.     {
5.         Debug.Log("OnTriggerEnter2D " + other.tag );
6.         if(other.tag == "Player")
7.         {
8.             other.transform.position = new Vector3(other.transform.position.x*-1, other.transform.position.y, other.transform.position.z);
9.         }
10.     }
11.  
12. }

Teleport V2 (transform.position condition)

Code (CSharp):

1.         public float rightEdge = 12.5f;
2.         public float leftEdge = -12.5f;
3.  
4.         public Vector2 TeleportOffset = new Vector2(0.5f,2f);
5.  
6.         private void Teleport()
7.         {
8.             if(this.transform.position.x > rightEdge)
9.             {
10.                 this.transform.position = new Vector3(leftEdge + TeleportOffset.x, transform.position.y, transform.position.z);
11.             }
12.             else if(this.transform.position.x < leftEdge)
13.             {
14.                 this.transform.position = new Vector3(rightEdge - TeleportOffset.x, transform.position.y, transform.position.z);
15.             }
16.         }

Teleport V3 (CharacterGO has to Clones as Child left and right)

PlayerCharacter has two Childs with all the same components and child transforms. The Position of the Clone childs is the same as the PlayerCharacter except the x value +/- Positionoffset (in this example transform.position.x = +/- 25)

Code (CSharp):

1.         public float rightEdge = 12.5f;
2.         public float leftEdge = -12.5f;
3.  
4.         public Vector3 TeleportVector = new Vector3(25f,0f,0f);
5.  
6.         private void TeleportV3()
7.         {
8.             // check if this is the root character
9.             if(this.name == "Left")
10.             {
11.                 // child clones do not teleport!
12.                 this.transform.position = this.transform.parent.position - TeleportVector;
13.                 return;
14.             }
15.             else if(this.name == "Right")
16.             {
17.                 // child clones do not teleport!
18.                 this.transform.position = this.transform.parent.position + TeleportVector;
19.                 return;
20.             }
21.  
22.             if(this.transform.position.x > rightEdge)
23.             {
24.                 this.transform.position = new Vector3(leftEdge, transform.position.y, transform.position.z);
25.             }
26.             else if(this.transform.position.x < leftEdge)
27.             {
28.                 this.transform.position = new Vector3(rightEdge, transform.position.y, transform.position.z);
29.             }
30.         }

 

What ...

So what does seamless mean? It looks like you're just moving the object from position A to position B in one frame update. If you have objects that need to move with the main character just parent them to the one object, move the object, then next frame un-parent them. They'll move right along with the parent. I'll be honest though. I'm not really grasping what you're trying to do...

 

in v3 i'm already parenting them and because collision should work on left and right side during the transition the CharacterGameObject needs those childs all the time.

- players should always be visible (can't run off camera)
- if player is moving left out of the camera boundary (is only partly visible) the other party of his sprites should be visible at the right edge of the camera boundary

Edit: Valves Portal has the same mechanic (Pictures)

sorry, can't describe it better in english.

 

You can't do it without the dummy models. Note the dummy does not need to be a deep clone of the original. It just needs to pass on the details from any collision.

 

i modified my character
every collider/trigger exists now 3 times in the character itself

for example child transform Head has one ReceiveDamageScript and 3 BoxCollider2D's

• one has -xOffset
• one has no xOffset
• one has +xOffset

with this design i dont need 3 ReceiveDamageScripts (one for each Character Clone)!
my dummy's (clones) only need:
+ SpriteRenderer
+ SetParentSpriteScript

is there a more efficient method?

 

@BoredMormon

is there a performance difference between design A and B? What would you personally prefer?

A) 1 GameObject with 3 BoxCollider2D and 1 TriggerScript
B) 3 GameObjects with one BoxCollider2D and one TriggerScript

I need to tweak this setup up, at the mement i can only seamless teleport in horizontal and i need vertical teleporting too. so i want to optimize it.

Aa) 1 GameObject with 5 BoxCollider2D and 1 TriggerScript for each body part
Bb) 5 GameObjects with one BoxCollider2D and one TriggerScript for each body part

1x Character (4 Body Parts) would result in

AaA) 4x 1 GameObject with 5 BoxCollider2D and 1 TriggerScript
BbB) 4x 5 GameObjects's with one BoxCollider2D and one TriggerScript
