Set Grid Value

With this action you can set a specific cell within the grid data structure to a value. You supply the variable that holds the grid index (as returned by the action Create Grid) and then give the x and y position (the column and row) for the cell to set, and then finally the value for that cell. The value can be any valid data type, but the x and y position must be whole integers within the bounds of the grid.

Example:

The above action block code creates a new grid data structure and holds its index value in a global variable. It then iterates through all the instances in the room and adds their unique ID value into the cell that corresponds to their position.
