# How do I sorting array X axis with it's Y axises?

• I have a 100 x 9 x 1 array.

X axis indicates 'UID' of objects.

Y axises indicate distance, HP, size, velocity, ETC...

in X axis, 'sort X axis' event works well. but problem is Y axises.

I want to sort X axis by values of Y axises.

So if I click HP button list should sort by order of HP....

Is it possible?

or should I try something else?

So do you actually store UIDs in the array or do you use UID as an index for X axis?

For example when you do Array Set At(5,0) to 99 - does it mean that UID of the 5th object's is 99, or does it mean that object with UID=5 has HP=99?

If you use UID as X-index and don't actually store it in the array, then you can't sort it!

If you do store UID in the array, you can swap columns 0 and 1 and sort, then swap them back.

Here is a demo:

Also, why do you need this array anyway? In C2 many things you normally would do with arrays, can be done much easier without them!

You can store all these values (HP, size etc) in instance variables. And then you can sort them any way you like using "System->For each (ordered)" and similar events.

I checked and it might be able to work so look into this... go into the array options and go to compare at xy

you get to compare the two values and then in the add actions part, you can set the x. looks like you can set at X and In the value part set at whatever your array is called .CurY not sure if that will work or not lol but might get you close. Good luck!

Thank you but I think this is not what i meant.

For example, there is a list like this.

X axis(UID) / Y1(HP), Y2(DISTANCE), Y3(SIZE) ...

125 / 100,421,1024

84 / 125,552,512

62 / 625,126,256

If I sort X axis in this array, it should looks like this.

62 / 625,126,256

84 / 125,552,512

125 / 100,421,1024

And I would like to these kind of array sorting.

(Order by HP)

125 / 100,421,1024

84 / 125,552,512

62 / 625,126,256

(Order by DISTANCE)

62 / 625,126,256

125 / 100,421,1024

84 / 125,552,512

(Order by SIZE)

62 / 625,126,256

84 / 125,552,512

125 / 100,421,1024

• So UID is in Y0?

When you set value at axis X in 2D-array, you actually set it at 0 index on Y axis.

So "Set value at (X=2) to 99" is the same as "Set value at (X=2, Y=0) to 99"

Have you tried my demo capx? It does exactly what you want.

And also consider doing this without the array. Since you are dealing with instances and UIDs, you should be able do all this easier if you use instance variables.

• oh... ok. i'll look into it more.

• Thanks. Problem solved perfectly with your solution.
