Non-fps type games.

[w0otness]

Hi,

 

How feasible is it in Leadwerks to create other types of games, mainly RTS type games? I ask because many game sdks such as this has its development workspace geared towards a specific gamestyle, (Leadwerks obviously being FPS).

[Thirsty Panther]

You can put the camera anywhere you want. So 3rd person, RTS ,puzzle anything you want to do is possible. It's just that as it stands Leadwerks is biased towards FPS. I'm sure this will change in the future.

I'm making an RTS game right now. The editor and all work fine and smooth during the making of it. You can basically create any kind of game with Leadwerks, you just see a lot of FPS games/tutorials because it's easy to set up.

@Evayr: How are you solving the pathfinding issue?

 

I tried to make a basic RTS too and worked nice so far. However the current pathfinding solution is not really usable for this kind of genre.

 

Mainly because the navmesh is only rendered once and does not take new build or placed units/buildings into account.

[AggrorJorn]

You can rebuild the navmesh on runtime. And not just the entire navmesh, also chunks of it.

Really? What would the command for that look like in C++?

Nothing too special actually:

world = World::Create();
NavPath *np = new NavPath();
np->navmesh = world->navmesh;
//np = np->navmesh->FindPath( Vec3(0,0,0) /*from*/, Vec3(5,0,5) /*to*/ ); //To use it
np->navmesh->Build( float maxedgelength, int callback(float progress) );
np->navmesh->BuildTile( int x, int y, float maxedgelength, float maxedgeerror );

Ah, an undocumented function. You cheater! Thanks Evayr!

[AggrorJorn]

Well most of these functions come directly from the Recast API.

Have a look in the docs.

so how would the same look piece of code look like on LUA?

[Genebris]

Yes, I would also like to know how to update parts of the navmesh in Lua.

[AggrorJorn]

As far as I know this is functionality lies within the navmesh class of recast. Unless these functions are exposed to Lua, the only way to access them is via C++.

You know, I think we may be able to expose some stuff ourselves. We should be able to wrap something up in our C++ project to be called in Lua. Now that means you would need standard and make a C++ project, but if you have standard then making a C++ project still allows you to use Lua but gives you more freedom to expose this kind of stuff yourself I believe.

[xtreampb]

Your talking about wrapping our own C++ functions and bind them using lua++ or luabind (or something like that)

[Rick]

You wouldn't have to use lua++ or luabind but you probably could if you wanted. Otherwise you could just create a normal C style function and expose it to Lua and have it do what you want.

[xtreampb]

how do you expose functions to lua? not real experienced in this and i am curious

If you look at the C++ Leadwerks API Josh has made some of his own functions around Lua that you can use or you can import the same Lua version and do the same thing but use Josh's Lua state.
