P2 Physics Questions

[iShellz]

How do i set a sprite to ignore the gravity.

 

and

 

Make sprite fall out of world bounds. 

 

Thank You

ad 2) you could try

sprite.body.collideWorldBounds=false;

ad 1) sprite.body.static =true;

but it doesnt ignore gravity then -- it is static (immovable)

Set the gravityScale value to 0, then it will ignore gravity. It won't "fall" out of bounds though, as there's no gravity

[valueerror]

afaik gravityScale is not available for p2 physics ??!   and for some reason 

 

body.static=true;  or    body.mass=0;    resets sprite positions to 0,0 now..

valueerror, I wrote about it in my topic , but haven't received the reply.

So gravityScale does not work in P2 physics 

 

 

Also how to check for overlap and no collision in P2 would be awesome 

[valueerror]

to me it seems like p2 has big advantages in terms of physics simulation but lacks a LOT of useful functionality you have in arcade physics..  but if you want materials and springs you have to go with p2..  

 

i really hope that all the arcade stuff will eventually make it's way to p2.. like.. body.touching.right    customCollisionProcessHandler, gravityScale, and much much more..

I would be all set with arcade physics if they had polygon support

gravityScale works fine, have uploaded an example of how to use it. One for Materials too.

 

Arcade will never have polygons (again), that is what P2 is for.

[valueerror]

thx rich.. looking into it.. could you tell us something about the body static behaviour too?

Got it now, i see the example.  Thanks bunches rich

 

 

edit, that did it thanks rich

valueerror, can try use: sprite.data.motionState = 2;

[valueerror]

thanks !  and for gravity scale you have to say  sprite.body.data.gravityScale    - no wonder i thought it didn't work..

Waiting for body.static fix.. And some other issues:
 

1) How to use applyForce?

when i try something like this:

sprite.body.applyForce(100,500,500);

sprite is just disappears without error messages.

 

2) Is it possible to drag p2 bodies with a pointer?

3) And examples with "constraint" dont work

http://examples.phaser.io/_site/view_full.html?d=p2%20physics&f=distance+constraint.js&t=distance%20constraint

Cant wait for everything work perfectly. Phaser is best.

[cucumber]

Found a way to use applyForce body.data.applyForce([1,1],[500,500]);

but i dont understand what it is for   I'm trying to make radial gravity to a point

If you're getting strange errors when using body.static = true. Its because you're using the old version of phaser! I got that same error so I replaced phaser.js with the new version of it and it worked
