Irrlicht Engine

If you are trying to make Sci-fi-version of counterstrike why dont you do this by creating a mod for half-life1/2 ???

The max polycount limit of 65535 is removed in IrrlichtNX which uses 32bit indices...

I think the purpose of the tutorials is NOT to show you how exactly something works but to show how it could work... and if you have a look at the API you will see that the changes are minimal and easy to get the result you want to have.

The collision-tutorial wants to show how irrlicht handles ...

Assume you have only two stati for SceneNodes :
Enabled (0x0001)
Disabled (0x0010)

1. ) Whenever you create a SceneNode use a ID (Enabled) in the constructor ( Have a look at the API which param it is )

2. ) Create a ray that selects all SceneNode with a specific ID.

Thats it.

To disable ...

Sry for posting...

i'll ignore your answers too if you post some...

Did you try using the SceneNode-IDs ?

For example group your scenenodes in two groups :
Enabled : (0x0001)
Disabled : (0x0010)

I think computing the positions for vegetation is overkill... placing them randomly may be ok, but that TriangleSelector will only work with very small areas.

This approach could be used in an editor which stores the generated data to a file that is later on used for terrain/veg.-loading

grouping is a good idea... at least for grass/flowers and brushes. I want my trees to fall if they're hit by something big, so grouping would be a problem...

I'll wait until someone comes up with a better terrain

How do you position your plants (height) ? Are you using the heightmap of the terrain to get the position for the plants ?

Im asking because i think the TerrainSceneNode is lacking a getHeight(X,Z) function ...

you could have a look at the API-Doc.

core::vector3df(X,Y,Z)

weaponNode->setScale(core::vector3df(6,4,4));
scale the mesh by 6 on the x-axis , 4on thy y-axis and so on

setPosition will position the mesh at x,y,z

weaponNode->setRotation(core::vector3df(0,30,0));
setRotation uses degrees so this ...

You could use a physics-engine like ODE and feed it with a less detailed version of the mesh that you are displaying... but i never tried that so you'll have to try it yourself.

please try one of the binary releases of ode and test again...

And try using SINGLE Precision if you compile it yourself.

I think this approach will look a little ugly when you have to scale your terrain, because all your plants will reside on the vertexes of the terrain.
I would prefer to specify regions with that vegetationmap (using colors) for certain plants and randomize their positions a little. I think that ...

Do you use a precomp. binary of ODE ? I had that problem when using a self-compiled version of ode...

Why not use setVisible(bool isVisible)...

If you want to disable other things like animations/positionchanges etc for your entities create a manager-class which holds a list of all your entities.
You could then add/remove your entities to/from that manager.

Updates for all your entities are ...
