c++ - Data structures: alternatives to logic bitmap/pixmap -


i have decided rewrite old zatacka clone of mine. old thing, running under allegro 4, utilizes logic bitmap, bitmap used non-display purposes, reflecting directly visible "what's on screen , doesn't move" bitmap, integers stored in represent logical meaning of things on screen, because game got quite colorful. things players see may of color possible, game remembers kind of object each pixels represents.

the new clone not supposed use allegro, write logic bitmap code myself. said, appreciate if suggested more efficient , precise alternatives.

structure must able kept bitmap/texture visible players. think worms game, utilizing player invisible ground type variations, or something. in addition, following methods must implemented:

  • checking if pixels in circle belong small (~6) set of "colors" given parameter.
  • painting pixels in circle single "color".
  • painting pixels in circle, (except/only) ones in small set of "colors" provided parameter, single "color".
  • painting silhouette of rotated, preprocessed if wish so, bitmap single "color". (that's tricky one: interpreting bitmap stupid polygon loads of right angles job?)

this minimum. if structure supports shapes other circles, that's great.

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

java - Are there any classes that implement javax.persistence.Parameter<T>? -

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
