convertToWorldSpace - cocos2d -

  • converttoworldspace

hi, i'm not sure understand how works. api states converts local coordinate world space.

let' have 3 sprites. spritea added scene , , spriteb added spritea. , spritec added spriteb.

- scene     - spritea         - spriteb             - spritec

and want convert spritec origin world

if do: [self converttoworldspace:[spritec cgpointzero]];

or this: [spritea converttoworldspace:[spritec cgpointzero]];

or this: [spriteb converttoworldspace:[spritec cgpointzero]];

or [spritec converttoworldspace:[spritec cgpointzero]];

shouldn't give same answer since transformed world coordinates? or go 1 node space parent node space ...until world space.

what correct answer see spritec position in world coordinates?

to find world space origin on spritec, take sprites parent, in case spriteb , ask world space of child:

[spriteb converttoworldspace:[spritec cgpointzero]];

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
