how to move the camera behind a model with the same angle? in XNA
- by Mehdi Bugnard
I meet are having difficulty in moving my camera behind an object in a 3D world. I would create two view mode.
1: for fps (first person).
2nd: external view behind the character (second person).
I searched the net some example but it does not work in my project.
Here is my code used to change view if F2 is pressed
//Camera
double X1 = this.camera.PositionX;
double X2 = this.player.Position.X;
double Z1 = this.camera.PositionZ;
double Z2 = this.player.Position.Z;
//Verify that the user must not let the press F2
if (!this.camera.IsF2TurnedInBoucle)
{
// If the view mode is the second person
if (this.camera.ViewCamera_type == CameraSimples.ChangeView.SecondPerson)
{
this.camera.ViewCamera_type = CameraSimples.ChangeView.firstPerson;
//Calcul position - ?? Here my problem
double direction = Math.Atan2(X2 - X1, Z2 - Z1) * 180.0 / 3.14159265;
//Calcul angle - ?? Here my problem
this.camera.position = ..
this.camera.rotation = ..
this.camera.MouseRadian_LeftrightRot = (float)direction;
}
//IF mode view is first person
else
{
//....
