'''INT''' flags

Flags is a predefined [[local variable]] which is used to manipulate [[graphic|graphics]] in a [[process]].

== List ==
{|
| ''Value'' || - ''What it does''
|-
| 0 || - Nothing happens
|-
| 1 || - Graphic is horizontally mirrored
|-
| 2 || - Graphic is vertically mirrored
|-
| 4 || - Graphic is translucent
|}

You can add up the numbers to combine the effects. A horizontally mirrored translucent graphic would need flags 4 and 1, so flags = 5 will do the trick!

== Example ==
To make the graphic of a process spin:
<pre>
Process mirror_graphic()
Begin
graph = load_png("image.png"); //load the graphic and assign it to the graph variable
x = 100; //Position the graphic 100 pixels
y = 100; //from the top and left of the screen
Loop
if (key(_l))
flags = 1; //if you press the L key, your graphic is horizontally mirrored
end
frame;
End
End
</pre>
This process will mirror its graphic as soon as you press L.
