ds_grid_height

Finds the height of a grid.

Syntax:

ds_grid_height(index);


Argument Description
index This index of the grid to find the height of.


Returns: Real


Description

This function will return the height of the given grid. This value is the number of cells the grid has along the y-axis and is always an integer, as shown in the image below:


Example:

var i, j;
for (i = 0; i < ds_grid_width(grid); i += 1)
   {
   for (j = 0; j < ds_grid_height(grid); j += 1)
      {
      if ds_grid_get(grid, i, j) = 1
         {
         instance_create_Layer(i * 32, j * 32, "Walls", obj_Wall);
         }
      }
   }

The above code will loop through the ds_grid indexed in the variable "grid" and if the value found in any specific cell is equal to 1, it will then create an instance of "obj_Wall" at the appropriate position within the room.
