Irrlicht Engine

I made a little diagram so that people can maybe better understand the trigonomety involved...

of course in the code the roation is given in degrees and you have to convert those degrees to radians in order to take the sin or cos of them. to ...

well, first... are the planets going to rotate arounf the spaceship? or around a certain point in space?

This was just a quick 3rd person set up... onPostRender eh? I'll look into that.

if the orbits are pure circles and only rotate about the x,z x,y or z,y axis's then just update their positions from a certain point using trig given the distance from the planet to the center point is the radius from which you derive ur trig functions

I decided that making the camera a child of the playernode was not the best idea because it restricts what you can do with the camera. Keeping that in mind I wrote a little bit of code to make the camera follow a character, position itselft and rotate appropriately based on the platernodes position ...

dont need to make your camera a child of the camera node... do something like this in your render loop


int cOffset = 0; // change this to rotate the camera around the character
int cZoom = 200; // radius.. decrease to zoom in, increase to zoom out

core::vector3df r = playernode->getRotation ...

u need to set the ellipoid radius... setEllipsoidRadius (const core::vector3df &radius)

my guess... ur collision response animator (if ur using one whichj i'm sure u are) may need some radial transformation

nevermind... i got it to work perfectly using bool keys method

I want to be able to handle multiple key presses at the same time... for example pressing up and right yields the code for up to run as well as the code for right. As my code stands now it will only handle one key press and not the other...
