How do I Randomize without repeating the previous instance?

Hello! I have a Lovely Candy Spite, with 5 independent Frames (5 colors) and I'm Spawning these candies from another object.

I've also a global variable called candyRandomizer wich has a default 0 value. Everything great from here :)

Right now I have the condition that once started the layout the candyRandomizer global variable should change randomly to a number from 0 to 4 with round(random(0,4)) which are all the 5 frames the candy sprite has :). This is the candy that should get to the end, and i have to destroy the remaining 4. Once 10 points are reached the candyRandomizer changes to another random number, which includes the same one selected previously.

My question is, there's a way to randomize but block previous selection until you reach the next 10 points?

for example

game starts: candyRandomizer variable = 0

then 1 sec later candyRandomizer = 3 thanks to round(random(0,4));

after 10 points

candyRandomizer = round(random(0,4)) but avoid repeat previous number (3). So could be 0,1,2,4.

After another 10 points could be now any random number but not the previous random number. And so on! :)

Thanks for your suggestions!

As can be found in the How do I FAQ for Construct 2 :

Obtain random numbers without repeat - LINK

So you should be able to apply this logic to the added fact that you want it applied only when generating "candyRandomizer" every 10 points of score.

A way to check that your score has reached 10 points is to check that (score)%10 is equal to 0.

Wow! Thanks Fib!!

I never had the time to check the new advanced feature and wasn't aware this function existed. This is so freaking handy! Thanks for bringing it up!

Cheers!

Thanks brunopalermo. Yes it's very useful. Definitely de-clutters the event sheets.

Yep. I used to use arrays and had some functions to shuffle and stuff. Lol. This new object does stuff I don't even understand... Gotta study the manual.

The sample projects definitely help to understand it too. Check out "Noise textures" and "Procedural terrain generation" from the Start Page in C3.
