An [[Role-Playing Game|RPG]] overworld is the map or background of an RPG project. It can often [[Scrolling (sprites)|scroll]] with the main character's movement to allow the viewer to travel among a rather large world. Other objects such as enemies in the world need to therefore have positions relative to the scroll of the background. The player's perspective is looking down at the character, rather than the player looking at the character from the side.
{{note|This tutorial assumes you have sufficient knowledge of [[Scrolling (sprites)|scrolling]]. If you need a refreshment, please read over that article.}}

== Main Idea ==
In the RPG, the player figuratively moves but remains with a static [[X Position (value)|x]] and [[Y Position (value)|y]] position. The world that is visually behind the character moves opposite the character due to the limitations of the [[stage]]'s size compared to the world's.

== Main Character Movement ==
Assuming scrolling is utilized for the gameplay, the following script can be placed in the main character sprite to scroll the background:
<scratchblocks>
when gf clicked //or during a moment movement is proper
go to x: (0) y: (0) //centers the character
forever
if <key [right arrow v] pressed?> then
change [scroll x v] by (-1) //to "move" right, scroll the background left
end
if <key [left arrow v] pressed?> then
change [scroll x v] by (1)
end
if <key [up arrow v] pressed?> then
change [scroll y v] by (1)
end
if <key [down arrow v] pressed?> then
change [scroll y v] by (-1)
end
</scratchblocks>

== Making Boundaries ==
Boundaries set limits on how far the world can be scrolled. The player sprite, who controls all scrolling, can have a modified script shown below to set boundaries of the world:
<scratchblocks>
when gf clicked //or during a moment movement is proper
go to x: (0) y: (0) //centers the character
forever
if <<key [right arrow v] pressed?> and <(scroll x) > (-960)>> then //-960 is the boundary
change [scroll x v] by (-1) //to "move" right, scroll the background left
end
if <<key [left arrow v] pressed?> and <(scroll x) < (960)>> then
change [scroll x v] by (1)
end
if <<key [up arrow v] pressed?> and <(scroll y) < (720)>> then
change [scroll y v] by (1)
end
if <<key [down arrow v] pressed?> and <(scroll y) > (-720)>> then
change [scroll y v] by (-1)
end
</scratchblocks>

== Enemy Movement ==
Enemies in an RPG often move to bring more excitement and challenge to the game. An enemy who remains still may not be as difficult to defeat as one who moves. Enemies must scroll with the over world because only the main character remains in a static position. When the world scrolls due to the player's movement, the enemy has to scroll ''with'' the background to justify the movement properly. The first step is to create the enemy sprites, which can be drawn in the [[Paint Editor|paint editor]] or imported. Enemies may have movement that differs from one another. To generate random movement in the over world, the following script can be used or relate to one's needs:
<scratchblocks>
when I start as a clone //assuming there are multiple enemies
go to x: (pick random (-220) to (220)) y: (pick random (-160) to (160)) //generates near the player
set [off x v] to ((x position) - (scroll x)) //justifies x position with the background
set [off y v] to ((y position) - (scroll y)) //justifies y position
forever
go to x: ((scroll x) + (off x)) y: ((scroll y) + (off y))
if <([y position v] of [character v]) < (y position)> then //if character below enemy
change [off y v] by (-2) //moves down
end
if <([y position v] of [character v]) > (y position)> then //if character above enemy
change [off y v] by (2) //moves up
end
if <([x position v] of [character v]) < (x position)> then //if character left of enemy
change [off x v] by (-2) //moves left
end
if <([x position v] of [character v]) > (x position)> then //if character right of enemy
change [off x v] by (2) //moves right
end
</scratchblocks>
Create a variable named "battle". When the battle starts, this will keep the battle from repeating over and over again.
Lastly, use these scripts:
<scratchblocks>
when flag clicked
forever
if <<touching [enemy v]?> and <not <(battle) = (1)>>> then
broadcast [battle v] //Make this the broadcast that starts the battle sequence.
set [battle v] to (1)
end
end
</scratchblocks>
