Hello I’ve a problem, I tryed to do a simple test in wich my player (first person) can move and shoot sphere, I’ve used for help, TestBrickWall , but I I’m not able to shoot sphere from the center of screen, this is my code .
[java]
public class Shoot extends SimpleApplication implements ActionListener{
//mat
Material mat2;
//player
private PhysicsCharacter player;
//physics

//They here to avoid instanciating new vectors on each frame

//terrain

//direction walk

Shoot app = new Shoot();
app.start();

[/java]
I think that the problem is here, in onAction:
[java]
Vector3f f= cam.getLocation();
bulletg.setLocalTranslation(f);
[/java]
I try to change cam.getLocation()–>>> x,y,z, variable but, when I move the mouse the sphere doesn’t cum from center.
Anyone with a little of expirience than me, can help me :)?
thanks in advance
thanks it work!!!
