Irrlicht Engine

Yeah, it's necessary, otherwise it just isn't possible to build gameplay. And unless you have gameplay, you don't have a level :)

The level of abstraction he already has is perfect. You create a scene node, for which there is some set of properties. All we need is the ability, perhaps just through ...

irrEdit looks like it's coming along very nicely. I've seen commercial game engines with less mature editors. I'd love to see irrEdit become a true game editor... it's almost there!

An editor's usefulness increases exponentially with its extensibility. Since irrEdit is closed source, how does a ...

Nope... not yet. I'm not an OpenGL guru, so I'll do it for D3D8/9, and create the classes for Ogl. Someone is welcome to take it from there. Software obviously won't bother with this.

If the Irrlicht author is fine with my implementation, I'll fork it over (once it's complete).

I added interfaces to Irrlicht that make it easy to create device-dependent vertex/index buffers.

With D3D, this allows the use of DrawIndexedPrimitive, as opposed to DrawIndexedPrimitiveUP. Basically, DrawIndexedPrimitiveUP, as documented by microsoft, always creates index and vertex buffers ...

Much appreciated... thanks Spintz

Hi Spintz,

I'm having an issue that perhaps you can shed some light on. My heightmap is fairly large, 512x512. From what I read here, it needs to be 513x513. Is this correct?

Here's the bigger issue (which may be related). I'm loading my terrain fine, with 5 max LOD. I scale the terrain by 4xz, so ...

Yeah, I'm trying to imply that there is no explcit 'drawing' of your navigation grid. If your map is simple, just generate the grid. You DON'T have to use something sophisticated like a nav mesh.

Perhaps you can modify the md2 code to interpolate between the last and first keyframes during a loop. Sounds like it doesn't do it by default... but perhaps there's a flag you should be setting? I'd have more insight, but I haven't used the md2 stuff in irrlicht.

A* can path anything... but he mentioned that he had a simple map, but didn't want to use pathfinding. If your map is simple, you can break it up into a simple grid and easily use A*, and it's not hard to implement.

a major problem with a* is that how would ir know if that square is part of the ...

Bump: No news on this? Any comments by the engine author?

Just FYI, if your levels are simple, pathfinding is also simple. If you represent your world with tiles (i.e. a grid), you can apply A* or any search alg to easily generate paths. Pathfinding is really quite easy!

I'm getting low frame rates on some hardware and I'm prototyping some optimizations, including the use of Draw(Indexed)Primitive in place of Draw(Indexed)PrimitiveUP.

Has anyone already conducted this optimization?
