Create functions to use them every where

Hi,

I wanna learn how to create function to use it in event sheet.

I wanna do this for example like in javascript or php :

I have 3 box as layer and i want to use a function to show specific box (with passing variable of object or id ) when i need a box.

I wanna create a function which i can call every where i want

For example with jQuery :

function ShowHideBox(var1,var2{

          $(var1).fadein(1500);

          $(var2).fadein(1500);

}

I wanna create in construct 2 a specific event sheet (will be included in all event sheet), called : functions in order to use my function

And then in other event sheet i want to call my function like in javascript with : ShowHideBox(); but how to do this in Construct 2 ?

Thanks a lot for reading me !

You have functions in C2. Insert new object in layout and select function.
