Building the Irrlicht mod?

BlitzMax Forums/BlitzMax Programming/Building the Irrlicht mod?

Hey,

I'm using gman's Irrlicht wrapper (or trying to) on Linux, and struggling with certain errors while building. I'm using Ubuntu 12.04 in 64-bit, which is already going to cause trouble, no doubt, but I've come fairly far. I've downloaded the engine itself, created a 32-bit binary, but building the mod itself with BMK gives me these errors:

And then, unsurprisingly, building the mod fails. I tried to leave out iguiskin_wrap altogether by removing its include in the rest of the mod, but it doesn't want to build any example code without this bit, so I guess I have to solve this problem.

Any suggestions?

Fixed it! And I'm very glad about it, too.

Seems the problem was to do with namespaces. I went through iguiskin_wrap.h and made sure all references to 'rect' were actually 'core::rect', and the problem went away. No errors whatsoever. I'm quite surprised (and pleased). Hope this helps someone else!

How is the irrlicht engine compering to xors and does it fully supported in blitzmax?


UNZ(Posted 2013) [#4]
I don't know xors so I have no comparision.

As far as I know gman wrapped the whole irrlicht engine v1.7.3. I know that it works on win and linux (dont have a mac). The current version of irrlicht is 1.8 though.
IMO it is a very nice render engine with easy to understand oop design. I decided to use irrlicht with BMax over minib3d (not oop enough and too much oriented at b3d. I wanted to improve) and orge (I read it has more power but it is a harder to learn as well and the BMax examples were not as good explained as the irrlicht ones)

I choosed irrlicht 'cause the wrapper seems very complete and irrlicht can open a lot of 3d files (including .b3d and .ms3d) and has a gui system and a particle system integrated. What I wanted were nice shadows (check), antialiasing (check) and per pixel lightning (check). Plus there is also a b3d.mod which wraps irrlicht in a b3d oriented style. Thats good to learn from if you know b3d.
At the moment I try to wrap newton game dynamics to use with irrlicht and I am advancing. Could become cool.


Hardcoal(Posted 2013) [#5]
what about phyics i didnt see anything about that..


UNZ(Posted 2013) [#6]
Irrlicht itself has only a small collision system (its more a renderer). Physics have to be added extern. Bullet physics looks awesome but I coudn't find a BMax wrapper and it is over the top for me. Newton Game Dynamics is another physics engine. There is no wrapper (at least for 3d I think) for this too but the api is very easy to use. I tested simple primitive collision with linux and windows -> works. It may not be the fastes engine but a few hundred primitives are possible.
I'm wrapping the dll functions a little bit to be more oop and easy to use with the irrlicht mod. WIP

I only wish for physx engine i only know it well but good work UNZ and god luck.
Thanks for answering me

@zcbeaton Thanks for finding the FIX.
I have had the same problem.
