Irrlicht Engine

How did those tests go, if you don't mind my asking?

It is the whole Line Of Sight concept that is worrying me. For instance, I plan on a max of 24 bots on each of two sides (48 total). Each bot will need to calculate LOS with each bot on the opposing side - huge amounds of collision detection there. Then, even more worrying - I need to tie A* in with ...

I have been deeply considering Irrlicht for a future project. However, after running some simple testing, I have come to the conclusion that collision detection used by the engine is extremely slow. For instance, if I open the ‘Collision’ example and replace the code used to create the three faeries ...

Several days and no replies to such a straightforward question?

How does one use additive blending (as opposed to standard alpha blending)? I hear that DirectX calls can be made through the ‘driver’ – but while setting the render state appropriately would work perfectly when drawing additional primitives into the scene, the majority of objects (such as meshes ...

When do you expect the next version to be released (or is this information which you do not wish to expose so as that you are not facing deadlines?)?

There also seems to be a problem when using setPosition() to move the level into the correct place - the entire mesh dissapears, but the collisions still read. Is there a way to recalculate the normals with a function call ,or will I need to add this myself? It is slightly difficult when dealing ...

In attempting to scale an OctTreeSceneNode (textured 3ds) using setScale(core::vector3df(40,40,40)), the result is that many of the polygons are not rendered until the camera is very close and all previous lighting effects are mysteriously disabled. Is this a comon problem? If so, how is it fixed (I ...

Thanks rt, I'd already tried building in release mode and it had not made a difference. I added the code, and the problem is solved. It confuses me a little though - if the filename string is empty, then why does it load the texture regardless?

Hey, I'm about to take a look at your camera. However, I am 100% satisfied with the camera and movment I have set up at the moment - not only does it not climb walls, but it no-longer moves slowly when you aim at the sky or at the ground (instead of moving towards the point the player is aiming at ...

I need the cursor control, but wish to do the movement myself. The simplest way I found (without looking too deeply - this is not my current project, I am just looking into it at this stage) was to rip out the movement code and then do it manualy, while leaving the cursor contol active. Can a normal ...

I have discovered more information. There is no error when using the Irrlicht ‘release’ dll that is included with the SDK. However, I had made some minor changes to the engine after downloading – basically just killing the FPS camera control so that I could do it all manually, giving much more ...

In attempting to load an un-textured 3ds file created with Anim8or, all is well. But after I add a material and texture to the object, I receive the following ‘error’ when loading:

Debug Assertion Failed!
