Irrlicht Engine

really!!!so cool,i hope you can help me to finish it!thanks

Hello nhsimon,
my code is very complex because I'm using technologies like COM/ATL so it won't really help you, besides the irrlicht code I'm using is very simple, you don't really need complex 3d/irrlicht code to get this project ...

It has been fun, but sometimes it's a bit annoying to wait for the ball to stop, but still fun to play.

I will use this in my project, good luck!

Hey guys, I just want to let you know that the carpc thing has a lot of users, and is a pretty useful thing, you can see wwwDOTmp3carDOTcom where there are many users subscribed to the forum.
Now for hsimon, I have been like 7 months developing what you are talking about, a carpc frontend, and I'm ...

It Works! Amazing man, thank you!

Hello all,
I want to move a node specyfing screen x, y coordinates, the dificult thing, for me, is that it has to conservate the distance to the camera.

I have tried a few variations of the following code, without succes:


line3d<f32> line = pDevice->getSceneManager()->getSceneCollisionManager ...

Man! That was not what I wanted to do, I'm sorry.
What I want to do is:


SMaterial *myMaterial = new SMaterial();
myMaterial->Texture1 = myTexture;
SMaterial &nodeMaterial = node->getMaterial(0);

//now I want to replace nodeMaterial with myMaterial,
//this works in my code and node shows the new ...

Hello.
I Want to get the material of a node and manipulate it, but not with the reference returned with getMaterial, I think you will understand better with some sample code:


SMaterial *pointerMaterial;
SMaterial &nodeMaterial = node->getMaterial(0);
pointerMaterial = nodeMaterial;


//Now I want ...

Well, after debugging I see it's imposible to create ECF_R8G8B8, isn't it?

only solution is to use ECF_A8R8G8B8, and I won't need to convert color format anyway.

I want to create a texture with ECF_R8G8B8 color format, this way it
matches the format of a movie and i don't have to convert color formats.

I have tried setting the flag:

pDevice->getVideoDriver()->setTextureCreationFlag(irr::video::ETCF_ALWAYS_32_BIT, true);

and I have also tried to set it ...

This is probably because of the color format. You can set it like this:

video::ITexture* texture = driver->addTexture(core::dimension2d<s32>(256,256), "mytexture", video::ECF_A8R8G8B8);
video::SColor *p = (video::SColor *)texture->lock();
p[0] = video::SColor(255,0,255,0); // set a value in the ...

I remember I had some trouble to get a tga, and had to use a bmp. The file was generated by a bitmap font generator and I had to do several conversions to make it work.
Well if there's not another solution i will have to mess again and try to get a tga.
Would be nice to get the bmp loaded correctly ...

No, BMPs don't have alpha channel, so the alpha value should be 255
but i get value 0 ¿?? that's the problem

No, alpha 0 is transparent and 255 is opaque. I don't know how you are copying pixels from the .bmp file, but the most common color bitmaps are 24-bit BGR. So you would have to be getting the alpha component from somewhere when you are copying pixels in.

I load the bmp in an irrlicht ...

Hello,
I have a scene node with EMT_TRANSPARENT_ALPHA_CHANNEL_REF flag enabled and it has a .tga texture with an alpha channel.
Now I'm copying some pixels from a .bmp file, bmp has no alpha channel, then the pixels copied should be fully opaque, right? Wrong! when displayed are fully transparent. I ...
