When I move the mouse, I break my scene node and update my rigid body. Note: I am using a wrapper to facilitate Bullet and Ogre integration. Then I do myRigidBody-> setOrientation (newOrientation) and it works perfect but when I move the rigid body it does not move as it should, that means that when...

I try to develop my FPS-Game, I need to move the player, but if I use dynamic-body, I change its rotation too, I think that I need to use the kinematic-body, but ... how to move the kinematic body ? Or How to disable the other axes? void PlayState::createPlayer(){ Vector3 size = Vector3::ZERO; // si...

I'm developing a mini-game for the University, he should use "bullet". It's an FPS and I need (for the moment) to move the main character, I guess the straight direction to the vector that looks at the camera.
How can I do that?

Muchas gracias!

One of these lines deactivates or the other active?

I have 4 rigid bodies, but I want to turn on and off your collision when I want, but I can not.
I'm using the OgreBullet wrapper, but it does not affect using pure code
I thought the line was "setActivationState" but it did not work.

Sr. @drleviathan Maybe what I need is easier. Maybe I'm making my problem even more complicated. Please watch the video that is in Outlook, I am trying to make a basic FPS game, I have a machine to shoot, that machine has animations, I need to detect when it shoots and hits one of those 4 targets. I...

Hi, I tried. Can you watch my video?: https://1drv.ms/f/s!ArGUObDbqeovhrlTduYarEGPEUb9Vw My full code is: void PlayState::createBullet(){ _contador++; string idBullet = static_cast<std::ostringstream*>(&(std::ostringstream() << _contador))->str(); Ogre::Entity* entBullet = _sceneMgr->createEntit...

Your weapon has local XYZ axes. I will assume it shoots along the local-Z axis. In order to shoot in the correct direction in the world-frame you need to figure out the direction your weapon's Z-axis points when transformed into the world-frame. Get the transform of your weapon in the world-frame a...

You mean this? btVector3 dirCam(_camera->getRealDirection().x, _camera->getRealDirection().y, _camera->getRealDirection().z); btVector3 shootDirection = dirCam * localZ; It does not work, the bullet moves much more in Y But, It is correct? MyMotionState* fallMotionState = new MyMotionState( btTransf...

Most of your code looks okay to me. If the bullet only shoots along Z-axis then my guess is: oriWeapon is not getting the values you expect. Print out the values of oriWeapon to verify that its values change with the mouse. By the way, I notice that you set the value of oriWeapon twice before you u...

Hi, I'm going to detail my situation so that someone can help me. First I want to clarify that I am using a translator because my English is not good. I'm using the Ogre3D rendering engine and I need to make use of Bullet Physics for my University project. The truth is that they have not taught us h...

I'm very noob in bullet, This is my full code: string idBullet = static_cast<std::ostringstream*>(&(std::ostringstream() << _contador))->str(); Ogre::Entity* entBullet = _sceneMgr->createEntity("Bullet"+idBullet+"Ent", "Circle.mesh"); Ogre::SceneNode* nodeBullet = _...

So, if I add that line automatically adds a dynamic body? My weapon moves, how can I do to shoot correctly ?. Currently it moves only in Z, but I do not understand how to make it respect the rules of the real world. If I shoot at the sky, the bullet must move in both Y and Z, if I shoot only straigh...

I need apply a impulse to my bullet object, but not works. void Physics::initObjects(){ collisionConfiguration = new btDefaultCollisionConfiguration(); dispatcher = new btCollisionDispatcher(collisionConfiguration); overlappingPairCache = new btDbvtBroadphase(); solver = new btSequentialImpulseConst...
