Irrlicht Engine

Oh... thanks for the clue... I forgot to initialize the UV coords of each vertex... Thanks

Hello. I have a problem with texturing my custom scene node. I use a texture 128x128 px and by default it looks like the texture matrix is scaled and moved a bit in a wrong direction. I set the wrap mode to repeat and texture scale: (1.0, 1.0) and it looks like repeated few times. When I change the ...

I have compiled the latest version of Irrlicht from SVN and two interesting things happened:

1) Occlusion queries didn't make the lensFlareNode hiding behind other nodes like buildings.

2) Suddenly all collisions (triangle selectors etc.) stopped working thanks to new Irrlicht o.O

Why is that ...

Thank you, that helped :) One other thing... same happens with lighting. I had some flat horizontal surfaces as custom nodes so setting normals like (0.0f, 1.0f, 0.0f) was working for lighting. What about irregular shapes? How to calculate normals for them? I set (1.0f, 1.0f, 1.0f) but that doesn't ...

I have a strange problem with my custom scene nodes. I create them in the same way as in the tutorial but while moving in the scene with FPS camera there are moments when those nodes dissapear completely and appear when I move and rotate the camera somewhere else. What may cause that problem?'

Lol... disabling mipmaps made it even slower... Is there any other simple API to draw images on an other layer of HUD which cooperates with irrlicht?

As I said it only gets the coords of one node... Here's the log:


pig0 pos: (524, 375)
pig1 pos: (-10000, -10000)
pig2 pos: (-10000, -10000)
pig0 pos: (523, 375)
pig1 pos: (-10000, -10000)
pig2 pos: (-10000, -10000)
pig0 pos: (523, 375)
pig1 pos: (-10000, -10000)
pig2 pos: (-10000, -10000)
pig0 ...

ok so here are the declarations and initialization of those variables:


core::array<IAnimatedMeshSceneNode*> pig;
core::array<vector3df> pigPos;
core::array<vector2di>pigPosXY;
int number_of_pigs = 3;

IAnimatedMesh* mesh = pScene->getMesh( (GetBaseAppPath() + "game/pig.x").c_str());
core ...

Hello everyone. I'm using irrlicght & Proton SDK for mobile 3D apps and I'm just curious about one problem... That method selects only one scene node out of my arraylist of them:


void DrawPigLifesStat()
{

for(int i = 0; i < number_of_pigs; ++i)
{
pigPosXY[i].X = GetIrrlichtManager ...

Ok so here is how do I do it. At the begining I init the img's and load all textures:



cam_rect[0] = core::rect<irr::s32>(10,10,273,223);
cam_rect[1] = core::rect<irr::s32>(283,10,556,223);
cam_rect[2] = core::rect<irr::s32>(566,10,839,223);
cam_rect[3] = core::rect<irr::s32>(566,230,839,440 ...

I only need to display those images. Not make textures of them... Any idea how could I simplify that process? Perhaps display them as a top layer with something else than irrlicht?

Ok... so I took the method code from SVN and mofified:


if (camera->isOrthogonal())
ln.start = f->cameraPosition + (lefttoright * (dx-0.5f)) + (uptodown * (dy-0.5f));
else
ln.start =f->cameraPosition;


to:


if (camera->isOrthogonal())
ln.start = camera->getPosition() + (lefttoright * (dx-0 ...

I did a little test and here are the results:

loading 640 JPG files & creating textures out of them takes 32 139 ms
loading 640 BMP files & creating textures out of them takes 26 700 ms.

One JPG file size is ~30 kB
One BMP file size is ~1.1 mB


Looks like that technique with uncompressed files is ...

The problem looks like it doesn't take the right camera position to start the ray from. And the camera with it's position is initialized for sure before using that method...
Here is the code:


scene::IMeshSceneNode *surface = smgr->addCubeSceneNode(100,0,999,core::vector3df(0,-0.4,0), core ...

Hello. I have a serious problem with that method with getting ray from screen coordinates. I passed the right 2d pos and an active camera, but it casts the ray in a completely different place in the scene. And the start point is not the camera position... One important thing is.. that the scene is ...
