Rotating billboard scene node (mariokart style)

Post by bitplane »

I just made my very first scene node :)

plant life, asteroids and bits of explosions and stuff that are almost in 3d.

Image

rotation frames are on the x axis, animation frames on the y axis. only ^2 bitmaps are supported. animation is untested at the moment until i automate making the bitmaps. I'm not sure which way it's facing at the moment either! (only just got it working)

I stole Omaremad's getTargetAngle function from the AI node and learned lots from Emil Halim sprite classes, thank you for those :)

source code and text exe here:

this is my first c++ class, so speed/layout/feature suggestions are welcome :)

Nice.

If anyone else, like me, get a Dx8 error when you try to run this, just substitute the irrlicht DLL with the win32-gcc one. The demo uses Open GL.
Should put something witty here I suppose.

BTW, Can this be used to make Y-axis aligned billboards with only one frame? Thats something I've been missing.

guys in the chat room (cant remember who, either armen or mm i think) said it's alread been done in NX++, they're called "axial billboards" arrarently. it was lots of fun to make anyway.. and i'm glad you all like it :)

As for the use, I've had this wierd vision of mini billboard tanks with rotating turrets, and armies of tiny soldiers made of 3 parts with comical facial expressions and hard-man stances, being blown to bits by the player who is high in the sky flying an alien ship... but that's at least one game away! :D

X- single frame has a bug at the moment, I think adding "lastimagex=-1;" to the constructor should fix it, but I'm working away with no compiler so it will have to wait til the weekend. :(
