Data Types & Variables

In MADRIX Script variables may be used to store different data. Each variable will be defined with a certain data type. This data type describes the kind of values the variable can store and the operations which are possible with the variable. Here is a small example to get a feeling for variables.

The following source code renders a yellow pixel on a random position each time RenderEffect is called. This is the script "SetRandomPixel":

void RenderEffect()

{

    color col = {255, 255, 0, 0};

    int px,py;                              

    px = random(0,GetMatrixWidth()-1);

    py = random(0,GetMatrixHeight()-1); 

    SetPixel(col, px, py); 

  //a color variable called 'col' is declared and its values are set to yellow (RGB)

  //two variables of type int are declared to store the coordinates of a pixel

  //coordinates for x and y inside the matrix are chosen by chance

  //the pixel is drawn on the matrix

}
