Using lowercase 'play' which causes a compile error.

The correct method to play an animation by name is Play with a capital P.

Fill both blanks to check if the Animator is currently playing the 'Run' animation.

💡 Hint

Common Mistakes

Using incorrect case for animation name.

Trying to call GetCurrentAnimatorStateInfo twice.

The method GetCurrentAnimatorStateInfo(0) returns a stateInfo object. We use IsName("Run") to check the animation name.

Using SetTrigger instead of SetBool.

Passing parameter name without quotes.

Use SetBool to set a boolean parameter. The parameter name is isJumping and the value is true.
