Change WasD into Horizontal and Vertical for mobile controls

Working on a 2d days styled survival game but my animation script needs to be changed into horizontal for the D-pad to work :/
[script]
using CnControls;
function Update(){
if(Input.GetKey("w")){
GetComponent.<Animation>().Play("upwalk");
}
if(Input.GetKey("s")){
GetComponent.<Animation>().Play("downwalk");
}
if(Input.GetKey("d")){
GetComponent.<Animation>().Play("rightwalk");
}
if(Input.GetKey("a")){
GetComponent.<Animation>().Play("leftwalk");
}
}

[script]

this is my script but how can I change this in positive or negative horizontal or vertical, can someone make an example for just one (so for example just W) so that I can try it myself on the rest?

 

Input.GetAxisRaw("Horizontal") returns -1 to 1 you can use that in your if statement

 

quick clarification
GetAxis() returns a float from -1 to 1.
GetAxisRaw() returns only -1, 0, or 1.

 

Yeah so Unity has its own smoothing function to mimic an axis in a way. So when you use the WASD keys it will gradual move from 0.0F to -1.0F/1.0F over time. This is from Input.GetAxis(string:name). Input.GetAxisRaw(string:name) does not smooth anything it always returns -1.0F, 0.0F or 1.0F.

 

How do I know if it is positive or negative, or how does the script know

 

put it in an if statement?

Code (CSharp):

1. float horizontal = Input.GetAxisRaw("Horizontal");
2.  
3. if(horizontal < 0.0F) {
4. // Left
5. } else if(horizontal > 0.0F) {
6. // Right
7. } else {
8. // Nothing on the horizontal
9. }

repeat for vertical.

 

Code (csharp):

1.  
2.  
3. Function Update() {
4. float horizontal = Input.GetAxisRaw("Horizontal");
5.  }
6. if(horizontal < 0.0F) {
7.   GetComponent.<Animation>().Play("leftwalk");
8. // Left
9. } else if(horizontal > 0.0F) {
10.  GetComponent.<Animation>().Play("rightwalk");
11. // Right
12. } else {
13. // Nothing on the horizontal
14. {
15. float vertical = Input.GetAxisRaw("Vertical");
16. }
17. if(vertical < 0.0F) {
18.   GetComponent.<Animation>().Play("upwalk");
19. // Left
20. } else if(vertical > 0.0F) {
21.  GetComponent.<Animation>().Play("downwalk");
22. // Right
23. } else {
24. // Nothing on the horizontal
25. }
26.  
27. }
28.  
29. [code]
30.  
31. apparently I need to add a semicolon to both floats which are already there ;( maybe I F***ed up the brackeys somehow? I feel like such a newb lol xD
