Hi,
I have tried to modify perfly to be able to use the keyboard
in the fly or drive mode because it's more precise than mouse
when using big models.
I would like something like that : + and - for increase and decrease
the speed. Up and down arrow to go forward and backward.
Left and riht key to turn. And some keys to go up and down.

For example, I put this for the '-' key to decrease the speed :

if (ViewState->xformerModel == PFITDF_FLY) {
        pfiInputXformFly *ff = pfiGetTDFXformerFly(ViewState->xformer);
        pfiIXformFlyMode(ff, PFIXFLY_MODE_ACCEL, PFIXFLY_ACCEL_DECREASE);
}

I doens't work.

To change view direction, I put :
            case PFUDEV_RIGHTARROWKEY:
              if (ViewState->xformerModel == PFITDF_FLY) {
                pfiInputXformFly *ff = pfiGetTDFXformerFly(ViewState->xformer);
                pfiIXformFlyMode(ff, PFIXFLY_MODE_MOTION, PFIXFLY_MOTION_HP);
                float pos[2];
                pos[0] = 0.7; pos[1] = 0.5;
                pfiInputCoordVec(pfiGetIXformInputCoordPtr(ff), pos);
              }
It seems not very good ... And that stops the fly and I can't move anymore
(without the help of the mouse ;-).

Someone have already done something like that before ?
Thanks in advance.

Luc.
