Irrlicht Engine

P.S. Problem Solved.

I see 2 ways use virtual ISceneNode * getSceneNodeFromRayBB (const core::line3d< f32 > &ray, s32 idBitMask=0, bool bNoDebugObjects=false, ISceneNode *root=0)=0 PlayerNode->getPosition().rotationToDirection(TargetNode); 2ways is using getSceneNodeFromScreenCoordinatesBB then getCollisionResultPos...

i try a luck ))
one of my first screenshoots, call him a "ghost house"
this is a great work of art, skip it - terrible sin:))

I write same code for converting terrain to NxActor, all whas perfect, but when i trying convert mash of model, my programm crashed data format is like the same, but why it`s happens? NxActor* Convert(scene::IMeshBuffer *mb) { NxBodyDesc bodyDesc; NxActorDesc actorDesc; NxTriangleMeshDesc* concaveDe...

great thanks

So this is a problem of Irrlicht, hardware, or node count?

im talking about getRayFromScreenCoordinates and getCollisionPoint

especially if you make strategy don`t set so big FarValue, it`s clip far from camera polygons

float use 4 bytes this value included in range for "long int"(signed or not) is exactly for float must also if believe to written: http://cplus.about.com/od/introductiontoprogramming/g/floatdefn.htm if you use getRayFromScreenCoordinates you also must use sentiment triangle selector. I had...

Please tell more about VBO, what is it?

LOD don`t needed, my models is already lowpoly(only 6 rectangles)

How i can hide objects when he is invisible or behind the wall?

Because when my camera don`t watch on terrain my FPS is still low.
This is that what worries me.

Hi people, I am interested how can enlarge performance of application or it`s trouble only with irr-engine? My programm show me 5 FPS and PrimitiveCountDrawn(0) return me 232873 But only my terrain use 262144 vertexes and 26214 pyramid with 5 vertex each. irrlicht does not assume the optimization re...

good idea ))

It is not legal to assign to this . Your code is also pretty weird. bool IGameObjectNode::LoadModel() { this = smgr->addAnimatedMeshSceneNode(mesh); // cant convert You are assigning a IAnimatedMeshSceneNode* to a IGameObjectNode* . There is no logical reason to do this. I don't really know what yo...

unfortunately problem still exists. :shock: i rotate the node around Y-AXIS 45 degrees. Everything is ok. And then i want to rotate the node around Z-AXIS 45 degrees. Now when i calculate the z unit vector; i get (1,0,1). (I don't use (0,0,1) vector because i want to rotate the node in its local sp...

PS Yes, because my player turns with camera

ericaus better for search on this forum, google not help in this case. Also for do this you need know basic geometry and in accordance with this set position for yours models. it`s standart in game movement: //fragment of my code //fragment from my code #include <math.h> // for sin/cos #define M_PI...
