Teleport physics body

Physics
#1

Hello everyone

I wanted to know what the best way for you to teleport a physical body. 

if I did not have a physical body, I would simply change the coordinates, but with physics?

looking for I found this tutorial:  https://coronalabs.com/blog/2015/09/24/tutorial-creating-awesome-water-with-liquidfun-snapshots-and-filters/

The Freeze!2 video shows a good example of teleportation(about 0:20).

In the video it even seems that the physical body slowly moves to the portal piece by piece…

  1. So that is the best way for a teleportation?

  2. Then replicating that teletraspot effect “piece by piece” is complicated?

As you can do this with a non-physics object:

obj.x = 100 -- move object to x == 100

So too can you do this with physics objects that have either ‘dynamic’ or ‘kinematic’ bodies.  You must however keep these details in mind:

  • isSleepingAllowedshould be set to false, or the body may not move to the new position.
  • Moving a ‘static’ object may not work as expected.
  • Moving the body discretely (as shown above) will not push other bodies in the path of movement.

Note: At 0:20 in the video, the designer has actually done this:

  1. Found some way (of which I can think of at least two)  to mask the rendered object so it seems to enter a portal.  

  2. Created a second object that ‘comes out’ of the other portal using the reverse rendering trick.

I’m sure I could work this exact effect out, but not in a few minutes.  (Hitman)

The key takeaway here is, there are TWO objects representing a single object in that video.

Final note.  If you are simply looking to create a screen wrapping effect (like asteroids), that is pretty easy.  

SSK 2 comes with a wrapping helper: https://roaminggamer.github.io/RGDocs/pages/SSK2/libraries/actions2/#scene-wrapping-scene

Perfect thank you very much

I imagined that he had used two bodies for that effect but wanted an outside opinion before.

For teletransport better than expected if it is sufficient to move its coordinates.

#6

I will test. if I can not, then I’ll use the hitman service

#7

Good luck on this, and if you do use the Hitman service be sure to clearly define the specific teleport effect you want.  There is a lot of room for interpretation here depending on the visual effect you are trying for.
