INT flags

Flags is a predefined local variable which is used to manipulate 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:

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

This process will mirror its graphic as soon as you press L.
