Doubt how to capture the character’s animation in Unity

Question

I’m trying to make a command that activates an animation when I press 2 keys of Keyboard and when I stop pressing one of them, this animation stops. For example I chose the "w" + "leftShift" key, when both are pressed I want you to start the animation, "RUN". When I stop pressing "leftShift", I want it to start an animation of walking "WALK", and last when I stop pressing "w", I want it to start an animation of stopped "IDDLE". Could someone help me? Here’s the command I’m trying to make work:

        if (Input.GetKey(KeyCode.LeftShift) + (Input.GetKey ("w"))) {
            animationController.PlayAnimation (AnimationStates.RUN);
        } 

Answer 1

Free up the operator && instead of +, if it is only the W rotate the walk animation. And use the method GetKeyDown() to identify a key pressed

if (Input.GetKeyDown(KeyCode.LeftShift) && Input.GetKey("w"))
{
    animationController.PlayAnimation(AnimationStates.RUN);
}
else if (Input.GetKey("w"))
{
    animationController.PlayAnimation(AnimationStates.WALK);
}

You can do it using a if within another:

if (Input.GetKey(KeyCode.LeftShift){
    if((Input.GetKey ("w"))){
        animationController.PlayAnimation (AnimationStates.RUN);
    }
} 

or you can do with the and using $$

if (Input.GetKey(KeyCode.LeftShift) && (Input.GetKey ("w"))) {
   animationController.PlayAnimation (AnimationStates.RUN);
}

The function Input.GetKey returns a Boolean you have to use logical operators for what you want to get, and you cannot add booleans, true + true there is no.

This code may help you:

if (Input.GetKeyDown(KeyCode.LeftShift) && Input.GetKey("w"))
   {
     animationController.PlayAnimation(AnimationStates.RUN);
     if (Input.GetKeyUp(KeyCode.w))
        {
          animationController.PlayAnimation(AnimationStates.WALK);
        }
   }
