Title: More complex movement of player
Post by: jkrassman on March 06, 2013, 01:12:02 AM

I can't wrapp this one around my head ;)

So I have been following the "game" tutorial and it seemed straight forward - and I picked up some nice coding in the end. I am in the learning phase of C# and therefore I do get stucked from times to times. I have never been working with networking and either with tasharens assets so I am like a bambi on ice :D


The tutorial game used a touchcontroller and the objects moved across the ground. I would like to know how to implement a little more real world "gameObject" that moves in all directions and using a thruster (Spaceship).

In my controlscript I am using these methods for steering:

1. _cacheRigidbody.AddRelativeTorque(new Vector3(0,0,-Input.GetAxis("Horizontal")*rollRate*_cacheRigidbody.mass));
2. _cacheRigidbody.AddRelativeTorque(new Vector3(0,Input.GetAxis("Horizontal")*yawRate*_cacheRigidbody.mass,0));
3. _cacheRigidbody.AddRelativeTorque(new Vector3(Input.GetAxis("Vertical")*pitchRate*_cacheRigidbody.mass,0,0));

   

and for thrust:

1. _cacheRigidbody.AddForceAtPosition (transform.forward * thrusterForce, transform.position);

And this is the class from the tutorial:

1. using UnityEngine;
2. using System.Collections;
3. using TNet;
4.  
5. public class GamePlayer : TNBehaviour {
6.        
7.         static public GamePlayer instance;
8.        
9.         Vector3 mTarget = Vector3.zero;
10.        
11.        
12.         public Vector3 target{
13.                
14.                 set {
15.                         tno.Send("onSetTarget",Target.AllSaved,value);
16.                         }
17.         }
18.        
19.  
20.         void Awake(){
21.                
22.                 if(TNManager.isThisMyObject) { 
23.                        
24.                                 instance = this;
25.                         }
26.                
27.                 }
28.        
29.         void Update(){
30.                 transform.position      = Vector3.MoveTowards(transform.position,mTarget, 3f * Time.deltaTime);
31.         }
32.        
33.        
34.         void OnNetworkPlayerJoin(Player p){
35.                 tno.Send("onSetTargetImediate",p,transform.position);
36.         }
37.        
38.         [RFC]
39.         void onSetTarget( Vector3 pos){
40.                
41.                 mTarget = pos;
42.         }
43.        
44.         [RFC]
45.         void onSetTargetImediate(Vector3 pos){
46.                 transform.position = pos;
47.         }
48. }
49.  

Any got a feeling for, how this should be implemented?

After applying your torque and force, sync the transform's position, rotation, rigidbody's velocity and angular velocity. As I mentioned in the email -- sync the effect, not the cause.

That said, it's generally easier to have input values set some controller values (if you had a ship controller, imagine it having XYZ torque and thrust values). These would then be the values you'd sync, with a periodic update of position/rotation for good measure. As an added benefit this way these controller values can be changed via input, or via AI -- and your sync logic would remain the same.
