Title: movement of the aircraft
Post by: EagleAlex on October 31, 2012, 08:29:34 AM

I try to create the engine of the aircraft (game) and all went well until moment when I had to move the plane a bit in the other direction. I need to rotate the nose of the plane and fly down there where he was looking ,but the plane went in the coordinates X ie forward as she possibly could if I had not turned. Tell me how can I make the plane fly out where to turn.

Rotation carries out

Code Select

 if (move_left) {
				model.rotateY(-0.01f);
			}
			if (move_right) {
				model.rotateY(0.01f);
			}

Moving backward/forward

Code Select

			if (move_backward) {
				model.translate(v.x, v.y, v.z+speed);
			}
			if (move_forvard) {
				model.translate(v.x, v.y, v.z-speed);
			}

Code Select

private void move() {
			SimpleVector v = model.getZAxis();
			SimpleVector s = model.getYAxis();
			SimpleVector t = model.getXAxis();
			
			if (forward) {
				camZ-=5;
			}

			if (backward) {
				camZ+=5;
			}
			if (move_left) {
				model.rotateY(-0.01f);
			}
			if (move_right) {
				model.rotateY(0.01f);
			}
			if (move_backward) {
				model.translate(v.x, v.y, v.z+speed);
			}
			if (move_forvard) {
				model.translate(v.x, v.y, v.z-speed);
			}
			if (fly_up) {
				model.translate(s.x, s.y-speed, s.z);
			}
			if (fly_down) {
				model.translate(s.x, s.y+speed, s.z);
			}
			if (to_vertical) {
				model.translate(t.x+speed , t.y , t.z);
			}
			if (to_horizontal) {
				model.translate(t.x-speed , t.y , t.z);
			}
	 }

I'm not sure if i get the problem...try to rotate around the axis returned by getYAxis() instead of doing a rotateY. Maybe that helps...
