i'd like to use this thread for another question on arrays: is it possible to initialize an array with values from start? i.e. core::array<int> array = [1,2,3,4] ? until know i would rather use core::array<int> array; for (int i=0; i<4; i++) array.push_back(i+1); but this doesn't help me when i have...

Hi, i want to check in what orientational relation a certain pixel is from a certain scene node and furthermore move the scene node to that position. the scene node may be a child from the camera at x,y,z my input coordinates are x=-1..0..1 and y=-1..0..1 on the screen. i could switch to pixels as w...

okay thanks a lot! i first tried to do this with vectors but failed due to the many forces. i now have it simple and smoothly working on my computer. however, do you know of one or two good threads or webpages about how to deal with accleration, speed, braking and reservedriving?

thanks again

hi there, i have a car moving due to user input. speed of the car is highly dependend of what resolution i use. it's faster with 800x600 than with 1024x768 or even 1280x800. i optimized all values to the latter one, but people with 4:3 displays should play the game as well. are the units of differen...

hi there i got a problem: i have a collisionresponseanimator attached to a scenenode which holds a rectangle (size=(2,1,1) at a certain position (x,0,0). the ellipse is also set to this size and the translation. the error: when rotating the scenenode to a new angle, the rectangle childnode rotates w...

Hi there, i'm doing a "top-view-car-drive-through-a-city"-game. nothing big, just a simple thing. I use a testscenenode as a car and a q3map as a city mesh. Viewing setup is: map is loaded in and rotated by -90 degrees around x, so it fits into the x-y-plane, camera is looking from -z into...

Why not trying up a .tga file with alpha channel selection ;) ? i didn't know how to do it. thanks to your advice I tried something with photoshop and it looks quite good. I assume I add an alpha channel and use the eraser or could you give me a short tutorial on this? thank you, sometimes you try ...

hi there, now i'm really stuck. hope some of you guys can help me out. i'm trying to create a 3d-user interface. however, starting with the basics I want to create round circular widgets. to keep it simple I put a circle image texture on a testscenenode (simple cube mesh) and make the corners transp...

hmm particlesys->setParticlesAreGlobal(0); seems to work

talking here helps, thanks for listening.

could anyone explain the difference between point emitters and box emitters, and why one is global by default and the other is not???

hi i got a pointemitter (working) and set it to a new position every frame (60fps). problem is, that the position is added to the old one, causing rate control (aka first order control, aka incremental position... this does not happen with a box emitter! this also does not happen to a testwisely inc...

hi there i'm working on 3d user interface that features circular buttons. as i'm not into 3d modeling, i'm planning to use simple rectangles with a circular texture and have the outer parts transparent the problem is to check if the mouse hovers across such a widget: a ray cast from mouse position i...
