Irrlicht Engine

Thanks, it worked. It is quite costly. For now I've figured out an alternate (call setScale only once I'm doing editing vertices).

However, why doesn't sceneManager->getMeshManipulator()->recalculateNormals( meshBuffer); work? It doesn't seem to be as costly as setScale.

Hi,

So I wrote a basic terrain editor. My terrain has a shader which uses normals (NORMAL semantic) to calculate lighting and the texture blending. However, whenever I alter the mesh's vertices's positions manually, then the shader won't update the lighting/texture on the mesh itself until I've ...

I thought that when "refreshing" the mesh (node->setPosition( node->getPosition() )) it would automatically recalculate the terrain triangle selector. But I'm probably wrong, I'll check it out, thanks.

Hi,

I use a very simple raycast function to get the Y height of the collision point from the camera to the terrain (cast ray from camera->getPosition() to camera->getPosition() + vector3df( 0, -10000, 0 ) ). However, after manually moving the terrains vertices up/down, the Y position of the ray ...

It's quite epic, well done.

Solved. I exported the .X mesh with wrong options, thanks to Bear_130278 for a helpful post which I found in the forum somewhere.

If anyone has this issue, just post here and I will tell you exactly what to do.

Does anybody have a idea how I could implement a simple function like bool OnGround() using IrrBP? I know how to do it with the default Irrlicht collision manager (shoot a ray from character base position to -10 by Y axis from character base position - if collided, then the char is on ground ...

So.. I imported a .X file which has a walk animation from frames 1-25. Whenever I press KEY_KEY_W I want the model to play the animation. This is the code I have currently.


if( torsoNode )
{
f32 frameNumber = torsoNode->getFrameNr();
if( frameNumber < 1 || frameNumber > 25)
frameNumber = 1 ...

Yeah, and then the FPS also drops drastically for some reason.

I tried to reproduce it, but I can't. It seems the problems root is deeper within my code.. :/

Here's what I'm basically doing, though. (pastebin links).
main.cpp
BugCulprit.h
BugCulprit.cpp

When I comment that snippet of code, then it renders fine ...

This is what I exactly do.

1) Create "Player" class before main loop.
2) In the main loop, I call player->Rotate(), which is basically this:


//offset is a vector3df.
//cameraDirection is f32.

vector3df rootPos = rootNode ...

Click me!

All I'm drawing is a IAnimatedMesh and a ILight.

I've traced the error to these lines:


vector3df rootPos = rootNode->getPosition();
camera->setTarget( rootPos );
camera->setPosition( rootPos + offset );
rootNode->setRotation( vector3df( 0, cameraDirection, 0 ) );


If I uncomment those lines of codes, then there's no graphical glitches ...

I'm trying to create a camera by writing this before the main loop.

ICameraSceneNode *cam;
cam = sceneManager->addCameraSceneNode();

It does create the camera.. however, the camera only displays half of the screen. The upper half is completely gray. Why is this so?

Oh my god, I seriously wish you would've told me that earlier.

Compiled now. So far so good! Nice!
