How should I do this animation or how should I aproach this dilemma?

So, I have a cube and I want to make a game where the cube jumps from a pylon to another and now I am at the point where I want to make the pylon fall if the cube stays on it more than a given amount of time.

I don't want to use physics or rigid body, I am using just transform.position and Raycast to click on the next pylon I want the cube to jump, I want to use animations, so if the cub stays more than a given amount of time on the current pylon, that pylon will fall taking the cube with it.

The problem is that I don't know what to do, where to begin; regarding animations in unity I only know how to do Animation Clips.

I would learn to do other things but I actually have no ideea how to approach this problem, what technique should I use to get the desired outcome, and how?

Solution

First you need to detect if the cube is on the pylon.
If it is, then you need to start a timer.
If the timer reaches 0 then the pylon falls.

You can use OnCollisionEnter to Detect if the cube has collided with (landed on) the pylon:

void OnCollisionEnter(Collision col)
{
    // Check if it is the cube that has collided.
    if (col.gameObject.name == "Player")  // Make sure to assign the Player Tag to the cube
    {
        // Start countdown timer.
    }
}

You could start a countdown timer using a coroutine. You will need to add using System.Collections; at the top of your class.

Call your coroutine using StartCoroutine(MyCoroutine());

IEnumerator MyCoroutine()
{
    // Wait for 3 seconds.
    yield return new WaitForSeconds(3f);

    // Make the pylon fall now.
}

This code will cause the game to wait for 3 seconds before doing something. How you make the pylon fall is up to you, you could use a RigidBody and set isKinematic from true to false as an example, but since you have said you don't want to use physics, you could translate the pylon downwards using Transform.position.

This should get you started.
