c++ - Apply physics to player using bullet physics -


so i've had lot of problems trying physics applied play using bullet physics. i've tried kinematic bodies unsuccess. trying trying use rigid body i've had little successfully. pasted below updating code player's matrix , rigid bodies location. question how update player's position correctly.

update player's rigid body , camera's matrix *the gcamera.matrix projection , view matrix's multiplyed together

 physics.playerbody->getmotionstate()->getworldtransform(k); k.getopenglmatrix(glm::value_ptr(gcamera.matrix));  btvector3 j; j = physics.playerbody->getlinearvelocity();  gcamera.position.x = j.getx(); gcamera.position.y = j.gety(); gcamera.position.z = j.getz();   btvector3 pastpos; pastpos.setx(gcamera.position.x); pastpos.sety(gcamera.position.y); pastpos.setz(gcamera.position.z);  gcamera.getinput(window);   float lvelocityx = sin(gcamera.horizontalangle * 3.14159265359 / 180) * 2; float lvelocityy = physics.playerbody->getlinearvelocity().y(); float lvelocityz = cos(gcamera.verticalangle * 3.14159265359 / 180) * 2; //physics.playerbody->setlinearvelocity(btvector3(lvelocityx, lvelocityy, lvelocityz)); physics.playerbody->setlinearvelocity(btvector3(gcamera.position.x, gcamera.position.y, gcamera.position.z));  bttransform t; t.setfromopenglmatrix(glm::value_ptr(gcamera.matrix)); physics.playerbody->getmotionstate()->setworldtransform(t); physics.playerbody->setcenterofmasstransform(t);

if want in control of player is, use kinematic. know you've had trouble that's best solution.

if want physics move player, need rigid body , apply forces move it.

it not possible move rigid body in reliable way. have had teleport objects in past have removed , added new rigid body, not want doing every frame player.

android - Get AccessToken using signpost OAuth without opening a browser (Two legged Oauth) -

i using signpost oauth access data magento server. have read various tutorials on same , reach point open browser user can enter credentials. however, per requirement have automate part. hence, user should not browser page. have set-up done on server side ( magento ), hit url , returned call page. same through program in android. i have tried below, consumer = new commonshttpoauthconsumer(key, secret); provider = new commonshttpoauthprovider(oauth_init_url,access_token_url, authorize_url); try { provider.retrieverequesttoken(consumer, oauth.out_of_band); log.d("tokens" , consumer.gettoken() + " -- " + consumer.gettokensecret()); } and request tokens. dont know how bypass next step. tried directly accessing accesstoken (stupid of me) provider.retrieveaccesstoken(consumer, "mycallback://callback"); no luck, ends in oauth.signpost.exception.oauthnotauthorizedexception: authorization failed (server replied 401). ...
