SOLVED / Set 3+ objects to exact locations in random order?

I have searched the tutorials and forums for an answer to this question and I could not find a solution.

So if you know of a tut, or an answer elsewhere, kindly post it in the reply.

I have 3 objects in a layout.

Sprite 1 at 100, 200

Sprite 2 at 300, 200

Sprite 3 at 500, 200

as seen below,

I just want to arrange them in random order on start of layout.

If you are able, please provide a capx.

Much much appreciated.

Thanks

Just in case the capx is lost in space at some time in the future I decided to post a tutorial,

because I think this info is very useful

For sure there another ways to do this, but what in my mind right now is like this:

Add global variable.

on start of layout set global variable to choose(1,2,3,4,5)

global variable = 1 --- set sprite 1 Y to x position - set sprite 2 Y to x position - set sprite 3 Y to x position

trigger once

global variable = 2 --- set sprite 1 Y to x position - set sprite 2 Y to x position - set sprite 3 Y to x position

trigger once

Etc...

Thanks A0Nasser,

I was writing this ( below) as you were posting an answer....

Alright, so I thought I had to use an Array

but I found a way to do it without and Array.

If there is someone out there who knows how to do this with an Array,

please post that method below.

Non Array method: Lets call it THE BRUTE FORCE METHOD :

RE:

Image:

Event #2 = System> Trigger Once /// <<<or this could be put into the 'On start of layout' line as well >>>

Action = System > (Global & local variables) Set value

Event #3, 4, 5 = System> (Global & local variables) Compare variable ///

Action = (Sprite) > Set position

Again,

if someone has a method via an Array, please post.

Move the action on event #2 inside event "on start of layout" ("on start of layout" run once)

MadSpy,

Sure that would work too. :-p

Any Array methods........ anyone

have a look at:

https://www.scirra.com/tutorials/599/si ... ay-shuffle

Solved with and Array.

Ok, I have done more research and have come up with an answer.

Thanks to kittiewan and the tutorial she provided here:

https://www.scirra.com/tutorials/315/generating-random-numbers-without-duplicates

The reason you want to use an Array is simple.

To reduce the amount of code and increase the number of variations when a sequence is generated.

If you happened look at the first example using The Brute Force Method

I coded in only 3 variations based on the random number that was generated,

but

in actuality there are 6 different possibilities. being : 1,2,3 ,, 1,3,2 ,, 2,3,1 ,, 2,1,3 ,, 3,2,1 ,, 3,1,2

Could I have coded those different possibilities in? of course, but what a hassle.

Anyway:

Here is the image of how I adjusted her code to my needs.

and here is the capx:

Here's another option using some placeholder position sprites at the different locations. For each sprite you want to place, pick a random unused position sprite and place it there.

random_position.capx (r200)

Wow, That is an interesting method, and an easy method too!

Thanks for sharing.

ramones

I tried to PM you but not sure if it went thru.

I have a question if that's ok.

What if there are 3 sprites with no animation frames?

How easy is that ?

Same thing, just swap Sprite for Family.

ramones

ok, thanks again.

Much appreciated.
