Issue checking for a state

just got an issue checking for state, if the state is in the idle state then the move box code should run, currently its not for some reason? i = AnimatorStateInfo

Code (CSharp):

1. void OnTriggerEnter(Collider other)
2.     {
3.         if (other.gameObject.name == "Game_Cube_red" || other.gameObject.name == "Game_Cube_Green")// if red or green box is on trigger
4.         {
5.             //Debug.Log("The state name is", i.IsName);
6.             if (i.IsName("Idle_State"))//if the Arm is not moving
7.             {
8.                 //move the box
9.                 box_target = other.gameObject;
10.                 is_parrent = true; //set back to false in animation
11.                 anim.SetTrigger("ReachDown");
12.             }
13.         }
14.     }

 

try these debugs, and tell us what gets printed.

Code (CSharp):

1. void OnTriggerEnter(Collider other)
2.     {
3.         Debug.Log(name + " hit an object. The Object was " + other.transform.name);
4.         if (other.gameObject.name == "Game_Cube_red" || other.gameObject.name == "Game_Cube_Green")// if red or green box is on trigger
5.         {
6.             Debug.Log("Green or Red Hit confirmed!");
7.             Debug.Log("The current state of i.IsName : " + i.IsName);
8.             //Debug.Log("The state name is", i.IsName);
9.             if (i.IsName("Idle_State"))//if the Arm is not moving
10.             {
11.                 Debug.Log("Idle_State Confirmed");
12.                 //move the box
13.                 box_target = other.gameObject;
14.                 is_parrent = true; //set back to false in animation
15.                 anim.SetTrigger("ReachDown");
16.             }
17.         }
18.     }

 

I cant add this line
Debug.Log("The current state of i.IsName : " + i.IsName);

Unity throws an error saying:
Operator + cannot be applied to operands of type 'string' and 'method group'

 

Just thought i would post the full code just in case their is something wrong further up.

Code (CSharp):

1. public class RobotArm_AI : MonoBehaviour
2. {
3.  
4.     public bool is_parrent = false;
5.     public GameObject box_target;
6.     public Animator anim;
7.     public Animation animm;
8.     public Transform newParent;
9.     //public bool state_idle = true;
10.     AnimatorStateInfo i;
11.  
12.     // Use this for initialization
13.     void Start()
14.     {
15.         //check the state
16.         // anim = GetComponent<Animator>();
17.     }
18.  
19.     // Update is called once per frame
20.     private void Update()
21.     {
22.         AnimatorStateInfo i = anim.GetCurrentAnimatorStateInfo(0);//Layer 1
23.      
24.         if (!Input.GetButtonDown("Fire1"))
25.         {
26.             //is_parrent =
27.         }
28.  
29.             if (is_parrent)
30.         {
31.  
32.             box_target.transform.SetParent(newParent); //passing in the transform and object name in the function
33.            
34.         }
35.         else //not parrent to Arm
36.         {
37.          
38.             box_target.transform.parent = null;//unparrent the gameobject
39.             box_target = null;
40.                
41.         }
42.  
43.         if(i.IsName("Robot_return"))                             //if (animm["Robot_putAway"].time >= 0.9f)
44.         {
45.             is_parrent = false;
46.         }
47.     }
48.  
49.  
50.     void OnTriggerEnter(Collider other)
51.     {
52.         if (other.gameObject.name == "Game_Cube_red" || other.gameObject.name == "Game_Cube_Green")// if red or green box is on trigger
53.         {
54.             //Debug.Log("The state name is", i.IsName);
55.             Debug.Log("The current state of i.IsName : " + i.IsName); // this throws an error
56.             if (i.IsName("Idle_State"))//if the Arm is not moving
57.             {
58.                 //move the box
59.                 box_target = other.gameObject;
60.                 is_parrent = true; //set back to false in animation
61.                 anim.SetTrigger("ReachDown");
62.                 //state_idle = false;
63.             }
64.         }
65.     }
66.  
67. }

 

can you show me the AnimatorStateInfo class. I need to see what IsName is. is it a string, an enum??? I hope it'san enum.

if it is you want to do something like

if (i.IsName() == AnimatorStateInfo.IsName.Idle_State)

 

its a built in struct in unity https://docs.unity3d.com/ScriptReference/AnimatorStateInfo.html
i am using it to check the name of the current state. Isname is a string

 

You created a local variable for 'i' in Update, rather than using the class level one.

 

So it worked by making i public changing line 10 into >

Code (CSharp):

1. public AnimatorStateInfo i;

so i guess that means that the On-trigger method wasn't picking it up then?
Great thanks for the help i will let you know if i have any other issues

 

Is line #22 now?:

Code (csharp):

1. i = anim.GetCurrentAnimatorStateInfo(0);//Layer 1

When you had 'AnimatorStateInfo' in front of 'i' on that line, it meant that 'i' was valid only inside the Update() method.

 

Yeah since the variable was local.
