DS development > Compile errors with 3D, lesson 2

#61466 - Maverick - Sun Nov 20, 2005 3:34 pm

I have worked through many compile errors in this code, but have not come across these before and am completely stumped.

The lines that are having trouble are:

glNormal(NORMAL_PACK(f32tov10(x),f32tov10(y),f32tov10(z)));

error: invalid operands to binary >>

glTexCoord2t16(f32tot16 (mulf32(u,intof32(1<<(3+x)))), f32tot16 (mulf32(v,intof32(1<<(3+y)))));

error: invalid operands to binary >>

MATRIX_LOAD4x4 = floatof32(-1.0F);

warning: overflow in implicit constant conversion

u8 red = f32toint(mulf32 (r,intof32(31)));
u8 green = f32toint(mulf32 (g,intof32(31)));
u8 blue = f32toint(mulf32 (b,intof32(31)));

error: invalid operands to binary >>

Once this is sorted it should compile(hopefully)

Any help would be much appreciated


Thanks

I have compiled those lines using f32 for x,y,z,u,v,r,g and b a and it didn't give me any error. If you are using fixed point for variables everything should be ok. Do you have the the most updated libnds?

Ive got it down to just the

MATRIX_LOAD4x4 = floatof32(-1.0F);

warning: overflow in implicit constant conversion

By removing anything im not using and using

glColor3b(1,1,1);

Instead of

glColor3f32(intof32(1),intof32(1),intof32(1));

I cant think of anything else.

Is there anything i could use instead of gluFrustumf32?

OK, i got it compiling, am using integers now.

But now that it is in a state where it should do something, it only does this:

[Images not permitted - Click here to view it]

it just displays two dots in the middle of the screen, i dont get it, its driving me crazy.

HELP!!!!!

Thanx
