Vector 3

I have a code here, but i cant get the character to turn/move on WASD as it should do.
I guess i need to use vector 3? but i cant figure out how to properly script with it.

The character just facing forward and do the forward animation no matter what key you press (wasd)

Heres the code

Code (CSharp):

1.         if(Input.GetKey(KeyCode.W)){
2.         transform.position += transform.forward * movespeed * Time.deltaTime;
3.            
4.         }
5.        
6.        
7.         if(Input.GetKey(KeyCode.S)){
8.         transform.position += transform.forward * +movespeed * Time.deltaTime;  
9.            
10.         }
11.        
12.        
13.         if(Input.GetKey(KeyCode.D)){
14.         transform.position += transform.right * movespeed * Time.deltaTime;  
15.            
16.         }
17.        
18.        
19.         if(Input.GetKey(KeyCode.A)){
20.         transform.position += transform.right * +movespeed * Time.deltaTime;
21.            
22.         }

 

Just use http://docs.unity3d.com/ScriptReference/Transform.Translate.html
Anyway in your code you should use

1. if(Input.GetKey(KeyCode.S)){
2. transform.position += transform.forward * movespeed * -1 * Time.deltaTime;
4. }

 

You should really go through some basic tutorials for Unity3D, especially through the interface which will show you how to use the input settings to make this a lot easier.

 

Try doing something like this :

Code (JavaScript):

1. var movementSpeed : float = 5;
2. var rotateSpeed : float = 2.0;
3.  
4. function Update(){
5.  
6. transform.Rotate(0,Input.GetAxis("Horizontal")* rotateSpeed,0);
7.  
8. transform.Translate(0,0,Input.GetAxis("Vertical") * movementSpeed * Time.deltaTime);
9.  
10. }

 

When you use transform.right and you want to move left it would be smart to subtract value, not to add. Same with transform.up and moving down.
Probably same mistake with animation.

Code (CSharp):

1.                if (Input.GetKey (KeyCode.W)) {
2.                         transform.position += transform.forward * movespeed * Time.deltaTime;
3.      
4.                 }  
5.                 if (Input.GetKey (KeyCode.S)) {
6.                         transform.position -= transform.forward * +movespeed * Time.deltaTime;
7.      
8.                 }
9.                 if (Input.GetKey (KeyCode.D)) {
10.                         transform.position += transform.right * movespeed * Time.deltaTime;
11.      
12.                 }
13.                 if (Input.GetKey (KeyCode.A)) {
14.                         transform.position -= transform.right * +movespeed * Time.deltaTime;
15.      
16.                 }

 

The thing is just to make the character rotate in the same direction as you press the buttons, forward seams to work, but when you press ASD, the character do not rotate right/left/backwards. I have tried the codes here with no success, and
Intense_Gamer94 code might work if my code was in Java, have some problems with the VARs to work in C.

 

Javascript is pretty similar to C#

Code (CSharp):

1. public float movementSpeed = 5;
2. public float rotateSpeed = 2.0;
3.  
4. void Update(){
5. transform.Rotate(0,Input.GetAxis("Horizontal")* rotateSpeed,0);
6. transform.Translate(0,0,Input.GetAxis("Vertical") * movementSpeed * Time.deltaTime);
7. }

 

These floats gives errors ""error CS0664: Literal of type double cannot be implicitly converted to type `float'. Add suffix `f' to create a literal of this type""

 

The code that Intense gave works just replace 2.0 with 2. However you should really consider learning a bit more on your own.


Here is a portion of the code I was talking about before:

Code (CSharp):

1.  
2. // Use FixedUpdate
3.  
4. input = new Vector3 (Input.GetAxisRaw ("Horizontal"), 0, Input.GetAxisRaw ("Vertical"));
5.  
6. // Add velocity to rigidbody down here
7.  
8. // End of required code for movement

Left the other parts as comments so you can try to find the answer though Intense already gave you the same method pretty much. If you don't understand what FixedUpdate is, Rigidbody, Vector3, GetAxisRaw, ect... you really do need to go through some tutorials, books, or documentation. It's going to save a lot of time.

Again your four if statements can be easily made into 2 lines for movement if you simply go follow some tutorials that I have no pasted below.

Maybe watch one on making a 2D game to get some practical experience:

and of course search documentation for how these things work or the web in general and do what we all do, trial and error. Really, it helps more than you to use these tutorials.
