X Y grid

[bubba]

 [21][22][23][24][25]    5

 [16][17][18][19][20]    4

 [11][12][13][14][15]    3

 [ 6][7 ][ 8][ 9][10]    2

 [1 ][2 ][3 ][4 ][5 ]    1
X 1   2   3   4   5     Y

Im trying to get a formula to get the X and Y values to equal the numbers inside the square. So I want X2 Y3 to give me 12 and ive tried a ton of things and cant get it to work. My cur one that fails alot is..

SP=(ValX)+(ValY*2)+(ValY*2) - (ValX-1)

Use an table?

R["1,1",number]=22)
R["2,1",number]=23)
R["1,2",number]=16)

etc...

25 of those can be a pain you know :P I was gonna start with 25 entity markers but thought i should use all E2

Just start with 1 at the top and go down, and then use Val = X+Y*Width

Val = X+Y*Width is wrong in his case.
When you fill in his 2 & 3 you get:
Val = 2 + 3 * 5 = 17

He starts with 1 instead of 0, it should be:
Val = X+(Y-1)*Width
Val = 2 + (3-1) * 5 = 12

[Riddler]

Bull is right, if you don't put in -1 you get X+Y*Width which when filled in for the first line you get 1+1*5 = 6 so you have 5 memory slots wasted. Arrays using this method still gives 2D and would also have less of a memory footprint than a table with a string index of "1,2"

Doesnt one of the RAMs act like a xy grid? i remember hearing that from somewhere, i never use them

I hope this doesnt look like im just giving code out O_o

interval(500)
while(Y<=Height &  ops()<4000)
X++
Index=toString(X)+","+toString(Y)
R[Index,number]=X*Y
if(X>Width){Y++ X=0}

There's your basic formula, edit as needed ^_^

runOnTick(1)

{
    X++
    Index=toString(X)+","+toString(Y)
    R[Index,number]=X+(Y-1)*Width
    if(X>Width){Y++, X=0}
}

Fixed.

Using a lookup table for that is plain stupid.

With that, he needs do every time:
Index = R[ X:toString() + "," + Y:toString() , number ]
Just to retrieve the index.

Use:
Index = X+(Y-1)*Width
