preset movements

Hi guys, Im looking for a good way to how set commands for a character control.

I.E.
down, forward and a button do something, or back, forward and a button

any idea how to code it?

thanks a lot

 

Code (CSharp):

1. void Update()
2.     {
3.         if (Input.GetKey(KeyCode.W))
4.         {
5.             Vector3 position = transform.position;                                  //  transform current position
6.             Vector3 forward = transform.forward;                                    //  3d direction the transform is looking at.
7.             transform.position = position + forward * speed * Time.deltaTime;       //  moving forward
8.         }
9.         if (Input.GetKey(KeyCode.S))
10.         {
11.             Vector3 position = transform.position;                                  //  transform current position
12.             Vector3 forward = transform.forward;                                    //  3d direction the transform is looking at.
13.             transform.position = position - forward * speed * Time.deltaTime;       //  moving backward
14.         }
15.         if (Input.GetKey(KeyCode.D))
16.         {
17.             Vector3 position = transform.position;                                  //  transform current position
18.             Vector3 forward = transform.forward;                                    //  3d direction the transform is looking at.
19.             Vector3 right = new Vector3(forward.z, forward.y, -forward.x);          //  2d clockwise perpendicular vector to (x, 0, z)
20.             transform.position = position + right * speed * Time.deltaTime;         //  moving to the right
21.         }
22.         if (Input.GetKey(KeyCode.A))
23.         {
24.             Vector3 position = transform.position;                                  //  transform current position
25.             Vector3 forward = transform.forward;                                    //  3d direction the transform is looking at.
26.             Vector3 right = new Vector3(forward.z, forward.y, -forward.x);          //  2d clockwise perpendicular vector to (x, 0, z)
27.             transform.position = position - right * speed * Time.deltaTime;         //  moving to the left
28.         }
29.     }

Some simple 2d movement on the xz plane.
This should get you started
