Irrlicht Engine

Hi,

i don't think there's direct support for this in irrlicht. Under Windows you can use Sleep(time), under Linux usleep(time) to suspend the program for time in ms. You will have to calculate for how long you have to suspend the program each frame to achieve the wanted framerate.

Hi,
you probably forgot to include irrlicht.h there - the compiler tells you it doesn't know what a IrrlichtDevice is.
Actually all SceneNodes and GUIElements in irrlicht draw themselves. The object-oriented way to go would be to derive from IGUIElement or one of its subclasses.

ok, a small update. I wanted to fill the entire window with a bitmap using CGUIImage as described above, but there was a one pixel wide border on the left and bottom, when creating the image like this:
g_gui->addImage(rect<s32>(0, 0, resolutionX-1, resolutionY-1));

after some playing around with ...

Hi,

today i started looking closer at the GUI of my game. IGUIImage is nice, but simply lacks scaling the image - I don't want a different image file for every resolution. Since there already is a overloaded version of draw2DImage in the VideoDriver, that can scale the image, changing GUIImage is ...

Hi,

I again have an issue with irrlicht not updating the AbsoluteTransformation of scenenodes for the rendering of the current frame. The core problem is basically the same I had with the updating of my camera, see: http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=9175&highlight= . I just ...

Good point, Guest. You're right, that it should behave exactly the same, no matter if you put it in your code after you setPosition(), setTarget() and setUpVector() or if you put it in the engine where I suggested.

But since this is neither documented anywhere (or maybe I just didn't find the doc ...

That's just in my testing code to make the effect as visible as possible and not to use any of my game variables.. What the sine does is make the camera move along the y axis back and forth. The constant numbers set the speed and the amplitude of the bouncing.

OK, source found, too:

insert
updateAbsolutePosition();
in CCameraSceneNode.cpp at line 218.

The problem is that the call (a few lines lower) View.buildCameraLookAtMatrixLH(pos, Target, up); used last frame's position. Because a call to CameraSceneNode->setPosition() updates the RelativePosition ...

Hi,

i am writing a game where the camera (instance of ICameraSceneNode*) is looking down on the game board. I attached the camera movement to the mouse but instead of the camera's view angle being constant (the camera's direction is!) it shakes and jitters. The effect is more noticable when the ...

Hi,
v.Y += event.KeyInput.Key == KEY_KEY_W ? 2.0f : -2.0f (you missed a minus in your text, whereas you have it in the code snippet)
is essentially the same as
if (event.KeyInput.Key == KEY_KEY_W) {
v.Y += 2.0;
} else {
v.Y += -2.0;
}
since this gets executed when KeyInput.Key is either KEY_KEY ...

if your system overheats when running at 100% you should recheck your configuration!

but acki is right, limiting a game to a specific fps, by delaying it with someting like sleep might be a good idea too. games running at 1000+ fps is just overkill...

I haven't looked at how getSceneNodeFromScreenCoordinatesBB() works but i reckon it must be checking if the ray intersects with any of the bounding boxes of all nodes in the scene and returns the one which is closest. So it's definetely doing more computations than my code. Using ...

Hi,
i'm doing a game in which i have a map made out of squares (so pretty close to a chess board) and i also have to check at which square the mouse is pointing. so here is how i did it: my map is a plane at z=0 (makes the calculations simpler), i then create a ray from the eye through the screen at ...

just 5 minutes later i found the function that i overlooked: which does exactly what i was looking for. problem solved.

Hi,

i want to use different Fonts in my game. One way I could do that is load font1, font2, etc. and use font1->draw(...).
But is there a way to use the IGUI... stuff with multiple fonts? That's much nicer because irrlicht manages its rendering and the available controlelements are quite convenient ...
