How to get direction vector

Hi.

I have this situation:

and I dont know how to get direction vector (marked on red). I need it to show Newton dynamics the direction in which the cannonball will fly.

Thanks for help

Cannonball simulation

Hi, I know that this isn't Newton dynamics forum, but many people here know a lot about Newton, there so i decided to ask. I'am writing simulation of cannon using irrlicht and newton. I managed to do Newton car for cannon cart but i can't make the cannon ball to move. I mean that I dont know how to ...

Ok that sounds nice, but could you show me some code that makes child object?? becouse I'am new to irrlicht and i don't know how to do that. Only question is, isn't it the same as: vector3df RelativeToCar(0,30,0); ((ISceneNode*)carnode)->getAbsoluteTransformation().rotateVect (RelativeToCar); cannon...

2 models: cart and cannon gun. I treat cart as Newton Dynamics Car, and cannon gun is only a Irrlicht Mesh

I searched i found this working: NewtonCollision* nMapCollision = NewtonCreateTreeCollision(nWorld, NULL); NewtonTreeCollisionBeginBuild(nMapCollision); int cMeshBuffer, j; int v1i, v2i, v3i; IMeshBuffer *mb; float vArray[9]; // vertex array (3*3 floats) int tmpCount = 0; scene::SMeshBufferLightMap ...

Problem with object rotation

Hi, I'am writing a simple simulation of cannon using irrlicht and newton dynamics. The problem is, i can't rotate it (lift up or down) I can make the gun to move with the cat: void _cdecl PhysicsCarSetTransform(const NewtonBody *body, const dFloat *matrix) { matrix4 mat; memcpy(mat.pointer(), matrix...

Camera folllowing car

Hi, I'am having a problem with camera. I want it to follow car. W tried: vector3df carPos = carnode->getPosition(); actualCamera->setPosition(core::vector3df(carPos.X+800,carPos.Y+800,carPos.Z)); actualCamera->setTarget(core::vector3df(carPos.X-800,carPos.Y,carPos.Z)); But it don't works like those ...

[solved] ITerrainSceneNode + Newton Game Dynamics

Hi, I'am trying to generate Newton Map Cillision for Newton World. I tried to use code from one of examples from Irrilicht tutorial site: terrainMesh = terrain->getMesh(); nMapCollision = NewtonCreateTreeCollision(nWorld, NULL); NewtonTreeCollisionBeginBuild(nMapCollision); u32 cMeshBuffer, j; int v...
