Shuffle your deck of cards easily with this ONE event!

Have you ever struggled to RANDOMIZE your array when creating your Construct 2 game?

Here is The Solution to fix your problem forever!

You only need:

- 1 Array

- 1 Line of Code (1 Easy & Simple Event!)

Just this!

How do you do this?

Step 1:

Set the Array Size to 0 (empty the array).

We are only using the X component.

Step 2:

Add Event > System > For.

Select first and last numbers in Array (example: from 1 to 10)

Add Action > Array > Insert.

Select Value: loopindex. Then select Index: int(random(loopindex))

That's all you need! Here is how your event looks:

How does this Magic work?

A good magician never reveals his tricks, hehe. You're lucky this time ;) Let's explain the magic behind this event.

First, we set the array dimension X to zero.

Then we use a For loop. We will insert every number to the array one-by-one.

We insert every number in a random position BETWEEN the already inserted numbers.

The first number is "1". We will insert it into position: random(1). This means in a random position from 0 to 0. Always zero. Our shuffled array is "1".

The second number is "2". We will insert it into: random(2). In other words: index 0 or 1. If random returns 0, the number is inserted at position 0 - our shuffled array is "2,1". If random returns 1, our shuffled array is "1,2".

The next number is "3". It will be inserted either at position 0, 1 or 2. In front of "1,2"/"2,1"; in the middle (like "1,3,2"/"2,3,1"); or behind them. We already have 3 shuffled numbers!

For number "7" or whatever. Before inserting, we already have 1,2,3,4,5,6 randomized. The shuffled array has 6 items. We will insert number "7" in a random position from 0 to 6. In the middle of all those numbers, in front of them or behind all of them.

That's the trick.
