Endless Elevator – Last Week of Beta Testing

Hi Harmony here,

I’d like to thank the wonderful Beta Testers who have signed up for our Open Beta of Endless Elevator over the last month. I was really surprised how many people responded to our call and very grateful to all those who provided feedback.

The Open Beta is still running for another week so there is still time to try the pre-release game: https://play.google.com/apps/testing/com.ZuluOneZero.EndlessElevator

Then head over to our Beta Landing Page if you want to give us some feedback.


Your feedback helps us make a better game – thank you!

One feature of our Beta Testing was opening multiple channels to provide users to get back to us. Not only did we use the Google Play Beta Feedback and Stars system but we also took feedback on email and through social media. One new thing we did was to incorporate a chat channel on our Beta Landing Page where users could provide anonymous feedback directly on to our web site. I feel that the anonymity of this format was a really important source of quality comments for us.

Happy Playing – Harmony Out.

The Coin Flip

Ah the coin flip! Simple easy and fun. The mechanism is a platformer mainstay. You run over a spinning coin (it glitters, it calls you) it pops into the air, and it’s yours!

The Endless Elevator Coin Flip !

This is how we do it…

There is a Rigidbody and Collider on both the coin and the player character. You can clearly see the spinning frame of the coin collider in the .gif above.

The collider acts as a trigger which is being listened for by our script which executes the “pop”.

The coin has a spinning script (and also a magnetic feature as a bonus for later).

The player has a couple of behaviours that handles the trigger and action.

The coin scripts – note the use of the slider to get the spinning speed just right.

Here we have the coin’s Rigidbody and Collider settings:

The Rigidbody isKinematic and the Collider is a Trigger

This is the script we use for spinning:

public class spinCoin : MonoBehaviour {

    [Range(0.0F, 500.0F)]
    public float speed;
	// Update is called once per frame
	void Update () {
        transform.Rotate(Vector3.up * speed * Time.deltaTime);

Simple and sweet.

This is the function that that handles the collision and the pop into the air! (It’s part of our character behaviours).

    void OnTriggerEnter(Collider otherObj)
        if (otherObj.name == "Coin(Clone)")
            var coin_txt = coins.ToString();
            coinsText.text = "Coins: " + coin_txt;
            Rigidbody riji = otherObj.GetComponentInParent<Rigidbody>();
            riji.useGravity = true;
            riji.isKinematic = false;
            riji.AddForce(Vector3.up * 40f,  ForceMode.Impulse);
            Destroy(otherObj.gameObject, 0.4f);

First of all we are incrementing our coin total variables and screen display.

The mesh for the coin is part of a child component so we need to call the Rigidbody attached to the parent object.

We set gravity to true so that it falls back down after adding the force and set isKinematic to false so we can use it’s mass to fall.

After a very short flight we destroy it (0.4 seconds).

As an added bonus here is the other coin behaviour for when a magnet power up is used in the game.

    private void OnTriggerEnter(Collider col)
        colName = col.gameObject.name;
        float step = speed * Time.deltaTime; // calculate distance to move

        if (colName == "chr_spy2Paintedv2")
            transform.position = Vector3.MoveTowards(transform.position, col.gameObject.transform.position, step);

This is when we make the collider really big on the coin. If the player gets in range of the collider then the coin moves like a magnet towards him. Which is kinda fun when there is lots of coins around and you feel like a millionaire just by standing around.
