i want to be able to make my ‘guy’ to walk arbitrarily instead of just forward backward.
I know to translate the whole ‘person’ forward and backward thinggy. I just wanna make it move like gaming thing. Of course, i dont need to make both button usable at the same time. just basic simple move.
TIA

Use the following code this may help u in arbitary rotaions
struct CAMERA
{
float position[3];
float orientation[3];
};
CAMERA cameraData;
init func()
{
cameraData.position[0] = 0.0f;
cameraData.position[1] = 0.0f;
cameraData.position[2] = -500.0f;
cameraData.orientation[0] = 0.0f;
cameraData.orientation[1] = 0.0f;
cameraData.orientation[2] = 0.0f;
}
DisplayFunc()
{
glRotatef(cameraData.orientation[0], 1.0f, 0.0f, 0.0f);
glRotatef(cameraData.orientation[1], 0.0f, 1.0f, 0.0f);
glRotatef(cameraData.orientation[2], 0.0f, 0.0f, 1.0f);
glTranslatef(-cameraData.position[0],cameraData.position[1],cameraData.position[2]);
}
keyDown func()
{
case LEFT :
cameraData.orientation[1]–; break;
case RIGHT : cameraData.orientation[1]++; break;
case UP : fLinearVelocity += 20.0;
// Update linear position
fTime = fTime * fLinearVelocity;
fXDelta = fTime * (float)(sin(DEGTORAD(cameraData.orientation[1])));
fXDelta += cameraData.position[0]; fZDelta = fTime * (float)(cos(DEGTORAD(cameraData.orientation[1])));
fZDelta += cameraData.position[2]; cameraData.position[0] = fXDelta; cameraData.position[2] = fZDelta;
break;
case DOWN :
fLinearVelocity -= 20.0;
// Update linear position
fTime = fTime * fLinearVelocity;
fXDelta = fTime * (float)(sin(DEGTORAD(cameraData.orientation[1])));
fXDelta += cameraData.position[0];
fZDelta = fTime * (float)(cos(DEGTORAD(cameraData.orientation[1])));
fZDelta += cameraData.position[2];
cameraData.position[0] = fXDelta;
cameraData.position[2] = fZDelta;
break;
}
}
