Irrlicht Engine

Here is a snippet:


virtual bool OnEvent(const SEvent& event)
{
cam_pos = camera->getPosition();

if(event.EventType == EET_MOUSE_INPUT_EVENT)
{

// Camera Zoom
if(eventp.Event == EMIE_MOUSE_WHEEL)
{
if(cam_pos.getLength() > 100 || cam_pos.getLength() < 600)
{
cam_pos = cam_pos.setLength ...

How do you rotate a vector to face a clicked point. Like in many RPG's when you click on a spot on the ground and your character changes his/her facing toward to clicked spot as he/she moves towards it?

I hope I am making sense.

Nope. Its from Rogue Spear.

Yes I have almost the same problem, but mine is distance based not positional: The node the ray intersects with is only "detected" if the camera is really close to said node. But in 1.51 the collision detection behaves as it should. Now some may say, "Well, if it works in 1.51 but not 1.6 then just ...

Thank you both for the responses.

To answer your question DavidJE13, I am getting my ray from getRayFromScreenCoordinates(), which according to the API returns a "Ray starting from the position of the camera and ending at a length of the far value of the camera at a position which would be behind ...

Is there a range limitation in 1.6 for GetSceneNodeFromRayBB() and GetSceneNodeFromScreenCoordinatesBB()? In Irrlicht 1.51 I was able to pick a node using either of the functions as long as the node was visible. In 1.6 the camera has to be REALLY close to the node (like within 200 or so) in order to ...

For legal reasons I understand why you wouldn't want to allow discussions of things that violate EULA's on your forums. However, I have noticed on several forums the trend for people to get their "feathers ruffled" anytime the subject of gmax exporter's is brought up. Its as if they have a personal ...

I spent several hours searching for this very same solution once I discovered that md3's don't cast shadows in Irrlicht. Its seems like more than a coincidence that none of the formats Irrlicht (and ORGE for that matter) support can be exported from gmax. Except md3's and ye olde md2's. I would love ...

Thanks for the tip. It sounds like quaternions ARE the droids I'm looking for! And looking at the source code is a brilliant idea. I spent so much time scouring the API documentation that I didn't even think of the actual source. Dee tuh dee.

So, a node's rotation is based on a vector3d, and a vector3d is made up of an x, y, and z of type s32 or f32. So what does the value of say z represent? Is it a range 2147483647 to -2147483648 ? Obviously not degrees unless we do some division. How would I make a 90 degree change to one of a vector ...

See...

Yes I get the same thing, except when using .md3 meshes which don't cast shadows at all...

...sound of crickets chirping...


Okay, so I was looking into this further, and I noticed all the tutorial examples use .md2 and .x and .b3d formats...no .md3's. So now I have to ask a broader question: Is anyone using .md3's in their own projects? And if so, do you use shadows? Do they work?

I ...

Okay, so its not just my .md3's. I used an animated .md3 from Quake3 and still no shadows...

I have a simple .bsp level which loads and show textures with no problems. I have three different models:

1) A medium-polygon animated character (.md3).
2) A low-poly non-animated statue (.md3).
3) Another low-poly non-animated statue (.3ds).

Neither of the .md3 models will cast shadows, while ...
