creating variables

What is a variable? Variables are data structures that can hold one piece of data while your game is running. They can hold either a number or a string. Custom variables are variables made by you or whoever.

There are two kinds of user variables

Global variables that exist across the entire game

Local variables which are defined in objects and only exist in-game within specific instances.

Creating them

There are many ways to create a variable. One is to use D&D by which you use the set variable buttion in the control tab.
Another way is to use GML(coding).


Ex(GML):
___________________________
chocolate=4
___________________________

If you want to know more PM me!

Names:
Variables can be up to 64 characters long im pretty sure. They can begin with a letter/number/underscore.




Decrementing:
Decrementing variables is to subtract one from a variable.

Ways:
________________________

chocolate -=1

________________________


chocolate = chocolate - 1

________________________

Incrementing:
Incrementing is to add 1 to a variable.
ways:


_______________________

chocolate +=1

_______________________ I prefer the first way

chocolate = chocolate + 1

_______________________




Wrapping:
This means you want a variable that only can have a value from 1 to 100. And it wraps it's value from 100 to 1.

if ( chocolate > 100 )
then chocolate = 1

if (chocolate < 1 )
then chocolate = 100


Drawing:

You can draw the value of a variable using GML(coding) function draw_text() or the Draw Variable action.
