TileDisplay

The TileDisplay class in Mini Micro is a display type that holds and draws a grid of tiles, small images taken from a larger image called a tile set.

No display is configured as a tile display by default. But you can make any display layer a tile display by setting its mode to displayMode.tile.

Methods and Properties

Method or Property	Purpose
TileDisplay.extent [columns, rows]	display size
TileDisplay.tileSet	Image containing tiles to draw from
TileDisplay.tileSetTileSize	size of tiles in `tileSet`
TileDisplay.cellSize	size of tiles on screen
TileDisplay.overlap	cell overlap, in pixels
TileDisplay.oddRowOffset	amount to shift odd rows horizontally; use 0.5 for hex rows
TileDisplay.oddColOffset	amount to shift odd columns vertically; use 0.5 for hex columns
TileDisplay.scrollX	horizontal scroll amount, in pixels
TileDisplay.scrollY	vertical scroll amount, in pixels
TileDisplay.clear toIndex	set all tiles to null (the default) or the given index
TileDisplay.cell(x, y)	get the tile index of cell x, y
TileDisplay.setCell x, y, idx	set the tile index of cell x, y to idx
TileDisplay.cellTint(x, y)	get the tint color of cell x, y
TileDisplay.setCellTint x, y, c	set the tint of cell x, y to color c

Example

The following example shows how to set up a TileDisplay, load an initial pattern tiles, and then dynamically change the tiles shown over time. (The main loop cycles through all 64 tiles in the demo tile set, changing the tile shown in the center of the display every 0.1 seconds.)

// prepare the display
clear
display(5).mode = displayMode.tile
td = display(5)
td.tileSet = file.loadImage("/sys/pics/TileShapes.png")
td.tileSetTileSize = 64  // size of each tile in the image
td.extent = [15, 10]  // columns, rows on screen

// set up the initial tile pattern
td.clear 20  // clear to tile 20 (dark blue circle)
for row in range(0, 9)
	td.setCell 0, row, 6 // tile 6 is a yellow square
	td.setCell 14, row, 6
end for
for col in range(0, 14)
	td.setCell col, 0, 1  // tile 1 is a gray square
	td.setCell col, 9, 1
end for

// main loop
cellIdx = 0
while true
	td.setCell 7, 5, cellIdx
	cellIdx = (cellIdx + 1) % 64
	wait 0.1
end while
