cocos2d iphone - How to destroy a body with CCPhysicsSprite -


i've realized ccphysicssprite different in few ways ccsprite. example, must set body before set position of sprite. believe 1 of these differences causing exc_bad_access error when try destroying body. call schedulesprite method in update method.

-(void)schedulesprite {  if ([testsprite physicssprite].b2body != null) { b2vec2 force = b2vec2(-5, 10.0 * [testsprite physicssprite].b2body->getmass()); [testsprite physicssprite].b2body->applyforce(force, [testsprite physicssprite].b2body->getworldcenter() );  if ([testsprite physicssprite].position.x < 0) { world->destroybody([testsprite physicssprite].b2body); [testsprite physicssprite].b2body = null;     } } }

i exc_bad_access pointing line

b2vec2 pos  = _b2body->getposition();

in the

-(cgaffinetransform) nodetoparenttransform

method, within class

ccphysicssprite.mm

thanks.

despite destroyed body, sprite keep doing stuff, may remove sprite parent also, like.-

if ([testsprite physicssprite].position.x < 0) {     world->destroybody([testsprite physicssprite].b2body);     [[testsprite physicssprite] removefromparentandcleanup:yes]; }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
