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. You must also set a target variable (which can be flagged as a temporary local variable) to store the returned cell value, and the value can be any valid data type. Note that the x and y position for the cell must be whole integers within the bounds of the grid.
Argument Description Grid The index (stored in a variable) of the grid to get x The cell position along the x axis to get (the column) y The cell position along the y axis to get (the row) Target The target variable to use to store the returned value
The above action block code gets the value in the grid stored in a global variable that corresponds to the instances position within the room. This value is then checked and if it is an instance ID value, the calling instance is destroyed.
