Summary
MatrixSet("MatrixName[Column,Row], "Image
Index")
sets an image (represented with image
index) into a cell that addressed with Column & Row.
MatrixGet("MatrixName[Column,Row], "VariableName")
reads image index from a cell that
addressed with Column & Row. The image index is
then stored in VariableName as an integer value.
MXCOL ===> Returns current
column
MXROW ===> Returns current row
Now, we can set any of images in a addressed cell.
|
MatrixSet("MatrixName[Column,Row],"Image
Index")
|
|
|
|
|
MatrixSet("MatrixName[Column,Row], "Image
Index")
sets an image (represented with image
index) into a cell that addressed with Column & Row.

MatrixSet("MyMatrix[2,1]","2")
MatrixSet("MyMatrix[4,3]","1")
MatrixSet("MyMatrix[2,4]","3")
MatrixSet("MyMatrix[4,4]","0")
Above mentioned scripts will set the images into the specified
cells :
How can we fill the whole matrix with a specified image?
RedBall=1
**Fill antire matrix with redball
MatrixSet("MyMatrix[0,0]", "RedBall")
Or how can we fill the specified row with a specified
image?
GreenBall=2
**Fill second row with
greenball
MatrixSet("MyMatrix[0,2]", "RedBall")
And we also fill the specified column with a specified
image?
BlueBall=3
**Fill fourth row with second row with
blueballl
MatrixSet("MyMatrix[4,0]", "RedBall")
How can we clear whole matrix or a specific part of
matrix?
NoImg=0
MatrixSet("MyMatrix[0,0]", "NoImg") **Fill whole cells with null image (no
image)
MatrixSet("MyMatrix[0,2]", "NoImg") **Fill second row with null image (no
image)
MatrixSet("MyMatrix[4,0]", "NoImg") **Fill fourth row with null image (no
image)
MatrixSet("MyMatrix[3,2]", "NoImg") **clear cell(3,2)

What about reading from matrix?
|
MatrixGet("MatrixName[Column,Row],"VariableName")
|
|
|
|
|
MatrixGet("MatrixName[Column,Row], "VariableName")
reads image index from a cell that
addressed with Column & Row. The image index is
then stored in VariableName as an integer value.
|
|
|
|
|
|
|
MatrixGet("MyMatrix[2,1]", "CurImg") **
CurImg = 2
MatrixGet("MyMatrix[4,3]", "NoImg") **
CurImg = 1
MatrixGet("MyMatrix[2,4]", "NoImg") **
CurImg = 3
MatrixGet("MyMatrix[4,4]", "NoImg") **
CurImg = 0
Note: if you use MatrixGet and the col or row is out of range
it returns -1.
MatrixGet("MyMatrix[7,5]", "NoImg") **
CurImg = -1 because our Matrix dimensions are
4x4

How can we know which cells is active (in other words selected
by user)? There are two variables that always represent
current Column & current Row.
|
|
|
|
|
MXCOL ===> Returns current
selected column
MXROW ===> Returns current selected
row
MXCOL & MXROW returns 0 if no cell is selected.
|
|
|
|
|
|
**Get the image index of the current
cell
MatrixGet("MyMatrix[MXCOL,MXROW]","MyVariable")
**Set the green ball to the current
cell
GreenBall = 2
MatrixSet("MyMatrix[MXCOL,MXROW]","GreenBall")
**Check the user whether selected a
cell or not
If (MXCOL=0 & MXROW=0) Then
Message("You should select a ball","")
End
