Wrap wont work on physics ball?

Hi

Capx

Link is modified with the functioning portal! Thanx to Yann's tips!

Edit: Capx is removed from server.

I am trying to build a portal in my "sortof" pinball meets angrybirds game and i want to do it by using the wrapping behaviour.

Im intending on having a invisible wall on the left and right side of the layout that moves in sync with the Y axes of the ball.

When the walls then overlap a portal sprite that are also on the left and right side of the screen, i intend to set the walls to some other position so that the ball can go offscreen and wrap around it.

This way i can keep the angle and speed of motion intact.

And thus i create the illusion of a portal.

To do this however i need the green ball to wrap around the play area and as u can see in the capx it doesnt.

Any idears on why it wont wrap so i can fix it?

Thanx in advance!

I really enjoy learning C2 <img src="smileys/smiley32.gif" border="0" align="middle">

If I remember correctly, teleporting a physical object causes it to travel the distance in one tick, which makes it unstable to calculate.

I suppose you can create a new ball in the opposite X or Y of the screen and give that ball a velocity of the ball that left the screen, then destroy the other one.

Yeah. Make sure you have read both physics tutorials, which discourages you from 'teleporting' physics objects.

Ah thanx on the advice!

IMHO you CAN "teleport" physic objects....I ve been doing it quite often, but if you do it "visibly" you have to expect strage things to happen

Maybe you can:

• store the current velocity of the object in variables
• teleport the object
• set the velocity to 0,0 to avoid weird behavior
• and then reset the velocity as it was next tick.

If you have some rotation you might need to store/lock/reset angular velocity as well.

Never tested though

Thanx Yann and Weishoupt

Il try the method yann is sharing.

Il report back when i do or dont have suc6.

Thanx Yann!

It worked <img src="smileys/smiley36.gif" border="0" align="middle">

The links below show pictures of how ive done it.

The CapX on the top of this page is update with the working version.

Is there any chance you could post your capx or the images again somewhere? I'm interested to see how you resolved this.

Thanks.
