I am trying to build a dinosaur running game in React much like google chrome's.

My idea is that I will run a function at the exact moment the object is suppose to hit the dinosaur, around 3 seconds

  function check4Death() {
        if (playerClass !== '') {
          console.log('safe')
        }
        else {
          console.log('nope')
          clearInterval()
        }
         }
    setInterval(check4Death, 3000)

This function checks to see if the player is currently in the air
As my method of jumping is adding and then removing a class from my playerClass object

  function Jump() {
    setPlayerClass('jump')
    setTimeout(() => {
      setPlayerClass('')
    }, 500);
  }

Instead of the function telling me either safe or nope every three seconds, I get this

I am very confused as to why this is happening, I have a link to my full code here
