Sorry, i screwed up the post so heres the edit

What is it you are trying to achieve? 
The character to not collide with the shop


What is the problem you are having? 
cant get the character to get to not collide with the shop. I've looked unit collision up on the fourms but i'm using true (only 1 of each x and y value) but others are using false (2 of each x and y value).

Assuming your collision detection is between rectangles, you need to have 2 x and y values per unit. If you only have one x and y, then you probably have a width & height, and can use those to create the 2nd x and y pair. From there, you just do what the tutorials tell you.

characterSprite := Sprite.New (Pic.FileNew ("character.bmp"))
Sprite.SetPosition (characterSprite, x, y, true);
Sprite.Show (characterSprite)

loop
    Input.KeyDown(chars)
    if chars(KEY_UP_ARROW) then
        if y < maxy - 16 then
            y := y + moveSpeed
        end if        
    end if
    if chars(KEY_DOWN_ARROW) then
    if y > 16 then
    y:= y - moveSpeed
    end if    
    end if

    if chars(KEY_LEFT_ARROW) then
    if x > 16 then
    x:= x - moveSpeed
    end if 
    end if
    
    if chars(KEY_RIGHT_ARROW) then
    if x < maxx - 16 then
    x:= x + moveSpeed
    end if 
    end if

    Sprite.SetPosition (characterSprite, x, y, true);
    delay (10)
end loop



For the sprite, it will only have 2 values since it is on true mode and i don't want to make it false

Use a little math to figure out how to transform those 2 values into the 4 that you need.

RE:Moving character\'s unit collision

-----------------------------------

you mean creating 4 new values?

(x,y)

x1 = x + 50
x2 = x + 100
???

You're getting there. Let's say your sprite is 50x50 pixels. (x, y) is in the middle of the picture. To get the top-right corner, you add half the width to the X value and half the height to the Y value; (x+25, y+25). Now that you have the top-right, you only need the bottom-left. How do you think you'd do that?
