c++ - Ogre3d scenenode array -


currently working on pcg city in ogre3d, getting close room marked city spawn city there. kind of @ loss on how "store" buildings array , checking positions handle collision. in method size of plane buildings need spawn in, after create _citynode, house building nodes in it. these set in for-loop. in buildings variable try buildingnode in array can check collision in method. have 2 questions:

  1. how buildingnode array?

  2. is method approach of "uniqueness of buildingnodes correct or need approach?

    void citymanager::generatecity(int sizex, int sizez, int _numberofbuildings) {  #if ogre_platform == ogre_platform_win32 file* fp; freopen_s(&fp, "conout$", "w", stdout); _rootnode = gamemanager::getsingletonptr()->getscenemanager()->getrootscenenode(); _citynode = _rootnode->createchildscenenode("citynode"); printf(" number of buildings: %d \n", _numberofbuildings); printf(" location of x: %d  location of z: %d \n", sizex, sizez); (int = 0; < _numberofbuildings; i++) {     ogre::scenenode* buildingnode = _citynode->createchildscenenode("buildingnode" + i);     ogre::entity* _buildingentity = gamemanager::getsingletonptr()->getscenemanager()->createentity("cube.mesh");      buildingnode->createchildscenenode()->attachobject(_buildingentity);     buildingnode->setposition(rand() % sizex , 50, rand() % sizez);     buildingnode->setscale(rand() % 6+1 , rand() % 6 + 1, rand() % 6 + 1);       ogre::vector3 buildingpos = buildingnode->getposition();     ogre::vector3 buildingscale = buildingnode->getscale();     //_buildings = new ogre::scenenode[buildingnode];     checkcollision();     checkentryway();      printf("positions of building nodes %f, %f, %f " , buildingpos.x, buildingpos.y, buildingpos.z);     printf("scale of building nodes %f, %f, %f \n", buildingscale.x, buildingscale.y, buildingscale.z);   } fclose(fp); #endif }

you can use stl container want, ogre::scenenode* compatible them.

as example can collect nodes in std::vector like

std::vector<ogre::scenenode*> buildings_; (int = 0; < _numberofbuildings; i++) {   /* ... */   buildings_.push_back(buildingnode); }

and later access them like

for (auto : buildings_) {   ogre::vector3 buildingpos = i->getposition();   ogre::vector3 buildingscale = i->getscale(); }

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...
