can't destroy p2 bodies created by 'convertCollisionObjects' from Tiled

Recommended Posts

this is how the array that contains all the physicsbodies is created

 polyline_bodies = game.physics.p2.convertCollisionObjects(supermap,"polygons");

i can then cycle over all bodies and flawlessly set collisiongroups, materials and so on.. but if i want to cycle through this array and kill the physics bodies in it

for (i=0; i<polyline_bodies.length; i++){        polyline_bodies[i].destroy()}

i get the following weird error:

Uncaught TypeError: Cannot set property 'body' of nullc.Physics.P2.Body.destroy @ phaser.min.js:23level0.update @ game.js:616

how can i destroy the bodies in there.. 

 

thank you !

well sorry..   as i already wrote twice the array "polyline_bodies" already contains the physics bodies (hence the name)

 

the is no property body on a p2 body..   there just isn't !  whatever you are doing you are doing something different..

 

if your code works than only if your array contains sprites..    sprites have a body property which has a sprite property (recursive)  in that case you should be able to call destroy() right away "polyline_bodies.destroy()" and it should work..

 

my question is:

i'm calling destroy() on a p2 physics body and it isn't working..  instead i get this weird error message from above..  

 

this only happens on p2 bodies that are polygons created from a tilemap..  

 

the only difference between a body that i can destroy and this one is that the first one also has a sprite.. the undestroyable body has sprite:null

Did you find a solution to your problem?

 

When using a body by calling var _body = new p2.Body(); _body is created containing p2.body.data and null parent.

 

So for matter of discussion lets make a new body and a sprite to it.

var _body = new Phaser.Physics.P2.Body(game,game.add.sprite(0,0),0,0,1);

 

calling _body.destroy(); will nullify the sprite, but since the sprite has it's own body that is not linked to our body our body.data will not be destroyed.

 

Lets make an body without a sprite:

var _body = new Phaser.Physics.P2.Body(game,null,0,0,1);

 

_body.destroy(); won't do anything to it, since it seems it will only, as you stated, recursively destroy the _body.sprite.body.

 

Right now I'm just adding and removing the _body.data from the world using:

game.physics.p2.world.addBody(_body);

game.physics.p2.world.removeBody(_body);

 

and then just nullify the rest, any other input on this?
