Just change the camera position and maybe disable the car itself for first person view for performance, you shouldn't need anything more ;-)

Hello Egon,

Just a little question about multiple rotations with multiple pivots on the same object.

I'm first setting a pivot, do a rotation then I'm changing the pivot and do another rotation but it seems that both rotations uses the last pivot I provided.

Is it intended ? If so, how could I do to resolve this issue ?

Thanks in advance!

Hello,

I'm currently working on my own animation module for my game. Very simple stuff with only textured rectangles and pivot nodes.
I don't want to use Bones or any other tool, the objective is to make mine ... and to avoid using any 3D modeling tools since I'm totally bad at modeling  ;-)

My problem is about rotations. If I have a character with head, torso, legs, arms, ... and I need to perform a rotation on the whole character I have no idea how to do it (without using setChild()).
I have a "main" object, the head in this case and this one turns perfectly with something like that :

Matrix mat = new Matrix( target.calcSub( head.gettranslatedCenter()).normalize()).getRotationMatrix() );
head.setRotationMatrix(mat);

But my problem are the other Object3D of the model, if I apply the same they just turn to the correct direction on their center axis but without moving of course.
I was thinking about a rotation on the Y axis, but no idea how to compute the angle they should turn.

Thanks in advance !

Yes I know, but nothing is generated with a modeler (Never used one before) , everything is done by code.

Finally I managed to understand the shaders and did one not based on normals but only affected by the distance to the light sources but ... still not okay since shaders are working by vertex to compute the distance to the light, I still have strange effects on texture.

Anyway, thanks for your quick support ;-)

By the way is someone is interested, this is the shader I made to test, only lightsources diffuse value affects the lightning and no normals are used.

Vertex Shader:
varying vec3 lightDir;
varying float att[gl_MaxLights];

void main()
{
vec3 vVertex = vec3(gl_ModelViewMatrix * gl_Vertex);
int i;
for (i=0; i<gl_MaxLights; ++i) {
lightDir = vec3(gl_LightSource[i].position.xyz - vVertex);
float d = length(lightDir);

att[i] = 1.0 / ( gl_LightSource[0].constantAttenuation +(gl_LightSource[0].linearAttenuation*d) +(gl_LightSource[0].quadraticAttenuation*d*d) );
}

gl_TexCoord[0] = gl_MultiTexCoord0;
gl_Position = ftransform();
}

Pixel Shader:
varying float att[gl_MaxLights];
uniform sampler2D colorMap;

void main (void)
{
vec4 final_color;
int i;
for (i=0; i<gl_MaxLights; ++i) {
if(att[i]>0) {
final_color = final_color + ( gl_LightSource[i].diffuse * att[i] * texture2D( colorMap, gl_TexCoord[0].st ) ) ;
}
}

gl_FragColor = final_color;
}


You can find the screenshot bellow, the ground here is made of some box, should have the same shading but you can clearly see the difference.

Maybe changing the normal of all cubes could help it but no idea how to do it ;-)

Also another little question about lights ... if I put a light high like a sun and then render an interior scene, the light is still applied inside the building, does that means there are no collision test for light rays ?

BTW ... the 8-bit retro style is what I want ;-)

Thanks for your help !

Yes but it's only working in big rooms, if I put it with a big ellipsoid on corridors the camera is moving in a not nice way.

I found a workaround ... I put setCulling(false) to the level when i'm indoor, it's not fixing the problem but at least the players cannot peak trough a wall to see the end of the level.
