param initialState- The initial state.

param stateList- The list of states.

const enemy = add([
    pos(80, 100),
    sprite("robot"),
    state("idle", ["idle", "attack", "move"]),
])

// this callback will run once when enters "attack" state
enemy.onStateEnter("attack", () => {
    // enter "idle" state when the attack animation ends
    enemy.play("attackAnim", {
        // any additional arguments will be passed into the onStateEnter() callback
        onEnd: () => enemy.enterState("idle", rand(1, 3)),
    })
    checkHit(enemy, player)
})

// this will run once when enters "idle" state
enemy.onStateEnter("idle", (time) => {
    enemy.play("idleAnim")

// this will run every frame when current state is "move"
enemy.onStateUpdate("move", () => {
    enemy.follow(player)
