Rotations ...

I don''t really understand your question, but you need to multiply the matrices together to have them both work.







It''s like my grandfather used to say, "Never quote your elders."

The only problem is that in my version of DirectX(called DelphiX) we don''t have neither RotationYawPitchRoll nor Translation so it''s a bit harder to do this ...

in fact my code looks like that

with dxInput do // this is the dxInput object
Begin // in c begin = { and end = }
if isUp in states then// if the key up is pressed
Begin
Pitch := Pitch+0.01 ; // Pitch = Real
D3DUTILS.D3DUTIL_SETXROTATION(World, Pitch);
dxDraw1.D3DDEVICE7.SETTRANSFORM(D3DTRANSFORMSTATE_World, World);
end;

if isdown in states then// if the key down is pressed
Begin
Pitch := Pitch-0.01 ;
D3DUTILS.D3DUTIL_SETXROTATION(World, Pitch);
dxDraw1.D3DDEVICE7.SETTRANSFORM(D3DTRANSFORMSTATE_World, World);
end;

if isLeft in States then
Begin
Roll := Roll +0.01;
D3DUTILS.D3DUTIL_SETZRotation(World, Roll);
DxDraw1.D3DDEvice7.SEtTransform(D3DTRANSFORMSTATE_World,World);
End;

if isRight in States then
Begin
Roll := Roll-0.01;
D3DUTILS.D3DUTIL_SETZROTATION(World, Roll);
DxDraw1.D3DDEVICE7.SetTransform(D3DTRANSFORMSTATE_World,World);
end

same thing for YAW

etc ...

Can you help me somewhere ?
if you can''t understand the code i can put it in C

thanx a lots and bye
