Teleports or portals

Teleports and portals can save the player some time or they can transport the player to a different place on the map, which can cause disorientation and excitement. The most common use case of a teleport is when player dies. When the player dies he needs to spawn at a certain location called spawn point.

Trigger

We first need a trigger which detects the player and maybe our objects as well.

Teleportation point

Then we need a specific place on the map to which the teleport or portal will transport us.

Implementation

• Trigger, which detects that player or objects has entered the teleport
• Position, which tells where to teleport our player or object
• Move player to a specific position

Teleport Transform

This is the simplest teleport we can make. However, it has a major flaw. If our object contains a RigidBody the teleportation might fail due to collision detection. When we move RigidBodies around, they still have to detect collisions and if there is a wall in the way, the player might get stuck. Lets make this teleport compatible with RigidBodies then.

Teleport Rigidbody

Now our teleport actually supports moving RigidBodies around. But we might want to filter only specific objects to be able to teleport. We can use object tag as a filter.
