Grid2D<T>¶
A fixed (but resizable) 2D grid of items.
Usage¶
Creation¶
// creates a 100x100 grid
Grid2D<float> myGrid = new Grid2D<float>(100, 100);
You can also define what value cells should have by default:
Grid2D<float> myGrid = new Grid2D<float>(100, 100, 1f);
Changing a cell¶
myGrid[3, 10] = 128f;
// or
myGrid.Set(3, 10, 128f);
Fill¶
You can fill everything within a rectangle with Fill().
int minX = 30, minY = 40;
int maxX = 50, maxY = 60;
myGrid.Fill(128f, minX, minY, maxX, maxY);
Clear¶
You can clear the whole grid with a specific value by using Clear().
// sets every cell to the default value
myGrid.Clear();
// sets every cell to 128f
myGrid.Clear(128f);
Resize¶
If the size of the grid suddenly doesn’t cut it you can always resize it.
The cell contents are kept the same and any new cells are initialized with the DefaultValue.
Growing the grid will allocate new arrays, shrinking will not.
myGrid.Resize(300, 100);
