Play animation until i stop pressing it

Hello everyone , i want to make that when i have pressing the button the walk animation should loop but when i press it , it plays for 3 sec then stops .
Can anybody help me how to play a animation until i stop pressing it .

 

Code (CSharp):

1.  
2. Float delaytime;
3. void FixedUpdate ()
4. {
5.   Float V = input.Getaxis("Vertical");
6.   delaytime = V > 0 ? 3 : delaytime;
7.  
8.   If(V == 0)
9.   {
10.    If (delaytime > 0.1f)
11.   delaytime -= Time.deltatime;
12.    else if(delaytime < 0.1f)
13.   delaytime = 0.0f;
14.   }
15. //
16.   anim.setfloat("walk", delaytime);
17. }

 

Visual Scripting forum category is for Bolt visual scripting which is the official Unity visual scripting system and it's mainly aimed at non-programmers so suggesting C# solutions is a bit counter-productive.

 

Yes sir
