Irrlicht Engine

Code: Select all

That makes the object be culled by the camera's view and its bounding box. I'm not sure if Irrlicht automatically culls custom scene nodes, but this definitely works.

Ah, great. That did it. Thanks for the help

I put a cout in my FlyingObjectSceneNode::render() to see how the position changed over time, and it keeps printing out even when the node isn't visible.

Alright, thanks for the tip about the scene manager, I'll put it in soon. What algoritm, does the default one use?

I recently realised that my render() on my scene nodes are being called even when the objects aren't on screen, is there a standard way in the engine of culling those that aren't visible? I thought it was done automatically, was kind of surprised to see them called.

Does irrlicht support selection by 2d-box somehow? I'm making a very simple space rts and want support the usual kind of "drag out a box and all units in the box get selected".

Otherwise, what's the simplest way of doing this? I'm making a 3d-game, very simple stripped down homeworld-ish rts.

Then a ShipSceneNode it is, thanks for the help

What's the standard/accepted way of associating an object(say a ship) with a scene node? My node selection by mouse is working now, but I'm not sure how to go from node to object.

Do I create a ShipSceneNode with doesn't change SceneNode, just connect it with my ship-object?

Got it working now I went with a pickable/non-pickable enum.

Thanks alot for the help.

I'm trying to select a scene node using mouse. In theory it's fairly simple, a line from where the mouse pointer going into the screen, see what node it hits and get that. The problem is that I always get the camera node regardless of where I click.

I thought about moving the starting point a short ...
