Irrlicht Engine

Updated the first post with a video of a demo stage.

In this demo stage, the player must hit the button (small square) with the bouncing ball, in order to open the door (big rectangle) and reach the end of the level.

Just a quick update:

We implemented an algorithm to determine if a portal fits on the wall the player clicked on. We decided to use line collision detection to search for adjacent triangles. This was a little troublesome, because there's no native way to detect collision between 3D lines in ...

Thanks for the tips!

Our next step now is to find out how to check for triangles adjacent to the one picked by the player.

Having the portal's size be bigger than the character' height is a very good idea. That way, we can guarantee that if a portal has been created, than the player can teleport ...

Me and a friend have started a project for rendering indoor portals in walls (like in the game Portal, by Valve) using Irrlicht.

We are still at a very crude stage but already have some nice things to show.

The code is not yet available because right now it's just a total mess. We are fixing it ...

Ok, I will try that!

Thanks for the answer!

Using that method gives me no guarantee of where the model will be looking at after the rotation. To know that, I must know where the model is looking at initially. And that's what I'm asking: where do I find this information?

I am sorry, but I read the first tutorial again (HelloWorld) and I could not find any references to what the initial rotation of the model is and wheter that depends on the md2 file or the engine.

I've created an AnimatedMeshSceneNode, using the sydney md2 from the tutorials. By running some tests, I found that the model has an initial rotation that makes it look in the direction of the X axis.

What I want to do is position the camera so that it looks like it is inside the model's head. The ...

How can I rotate a scene node around an arbitraty vector?

The setRotation() method only alows me to rotate around a scene node.

Thanks!

Nevermind, the matrix had a getRotationDegrees method that returns what I need for the setRotation method on the node.

Thanks!

How do I apply the 4x4 rotation matrix to the node?

The setPosition method only accepts a vector3df.

Thanks for the answer!

Say I have a triangle with normal X. How do I rotate so it has a given normal Y?
