How do I set a conditional random?

Hello all,

In my game I have a screen full of 26 letter sprites, each one a different letter of the alphabet. I want to make them shuffle so they are in different spots every few seconds to make the game much more challenging. However, I only want one instance of each letter on the screen. I know I can spawn a random letter by using spawn another object> Letters(Family). However, I don't know how to give it the condition to not pick one already on the screen. Any Ideas?

Thanks,

William

What do you think about an array?

You could mix it, pick numbers/letters, ...

I think you get a good idea with this tutorial

I was going to suggest the same solution/tutorial, so take that as a second vote.

But my letters are objects, and cannot go into an array? I know how to build an array and randomize it, but what values in the array would let me spawn corresponding objects? I was thinking ID's, but you cant't spawn objects based on that in construct2

No...but

How do I load a family into an array?

maybe you can use one sprite with 26 frames?

korbaach,

That looks like it works for display, but i need my objects to be interactable; The user needs to click on them and they in turn perform actions based on their value (Each letter has a variable of it's own alphabetical value). I don't believe there is a way to have it all in one object with 26 different values? Any Recommendations?

Thanks, William

.....Unless I use the current frame number as alphabetical value? I could create an array with each alphabetical value("A-Z"), index 0 is A, index 25 is Z......I could say if

LetterArray.at(Letter.AnimationFrame) = uppercase(mid(WordArray.At(index),index2,1))

Then correct?

Am I crazy or does that sound viable?

you have frames 0,1,2..etc..&you set array(width=26) with index 0,1,2...then you can simple set value to Array.At(Sprite.AnimationFrame)..
