Flight movement on a Terrain
Author
Hi folks
I''m trying to make a flight game, you are controllning a ship flying above a Terrain.
I have trouble with the flight engine, can''t seem to get the movement correct =/, would need some math formula help. Small code parts would be helpful (programming language don''t mather).
Problem: Lets say the ship data is
position 50,20,20 (X,Y,Z)
Angels 0,0,0 (X,Y,Z)
MoveSpeed 2
at this point the ship is just moving forward in the terrain.
Then i press some keys witch change the angles to 10,10,0.
The ship should now be moving some units up and some units to right or left, and some uits forward, how do i calculate the movement ?
Thanks in advance.
well, you need a bit physics to get your ship moving.
you also need an orientation matrix for your ship. That would be helpful.
Something in that vein would work.

Vector Position;Matrix Orientation;float EnginePower;//.....//.....//.....void Update(float dt){ // rotate the ship given a set of controls Vector RotationAngle; RotationAngle.x = ((KeyPressed(''s'') - KeyPressed(''w'')); RotationAngle.y = ((KeyPressed(''<'') - KeyPressed(''>'')); RotationAngle.z = ((KeyPressed(''d'') - KeyPressed(''a'')); RotationAngle.x *= MaxPitchVelocity * dt; RotationAngle.y *= MaxYawVelocity * dt; RotationAngle.z *= MaxRollVelocity * dt; Matrix Rotation; Rotation.FromEuler(RotationAngle); // convert from euler angles to a matrix Orientation = Rotation * Orientation; // update the orientation of the ship Vector Dir = Vector(Orientation.e13, Orientation.e23, Orientation.e33); // new direction of travel of the ship Position += Dir * (EnginePower * dt); // move the ship forward}Something in that vein would work.
