//Tis code works but's in accurate.. not sure why.. pre-warning you are about to see some bad math

Also:
Plase asume these facts to always be true, the variable "backdrop" is just an image of a map loaded and resized to a small map at the corner of the screen.
And find that the variable "Player" is also an image loaded into memory;
Finally that the variable "MiniMapDot" is a tiny 8x8 image of a blue square(Much smaller that the image of the map previously loaded).




//It's just a really small sprite(Tiny cube) that mimics the position of a larger sprite's down-scaled x and y axis.

I need assistance in make this code more accurate .. or just an explanation of what i should be aiming for.

First, what is the purpose of the square root of the size of the sprites?

Since the size of the display definitely won't change and the size of the sprites probably won't, why don't you have all of that information stored once in variables?

In what way is it not accurate?

If...
1) ...the mini-map is just a smaller version of the main map
2) ...the main map is on the world plane
and
3) ...All objects on the main map are represented on the min-map

Then you don't need to redraw anything.

You can use setscissor in conjunction with setviewoffset and setviewzoom to have AppGameKit redraw the small version for you.

I did something similar a while back.
