tiles and animations?

[hertzcastle]

hi!
building my first tilemap as per the tutorial in the documentation section, thats fine, BUT, wouldn't it be a lot simpler from an artist point of view to load a sheet of tiles instead of individual tiles, like just in one image file?
that way when you hit save in your graphics app, every tile is updated.
i was thinking about how this idea would apply to love, and found animation:seek()
The basic idea would be to set the cell width and height to the size of your tile and then use maybe

Code: Select all

local x = 1
local y = 1
for i, v in ipairs(map) do
	tileMap:seek(i)
	love.graphics.draw(tileMap, x * wTile, y * hTile)
	x = x + 1
	
	if x > (wMap) then
	x = 0 
	y = y + 1
	end
end

where map is a numeric table, tileMap is the animation, wTile is the width of the tile, hTile is the height.
Any ideas why this doesn't work?

sorry, got it wrong, need to iterate like this:

Code: Select all

for y = 1, hMap do
	for x = 1, wMap do
		tile = map[y][x]
		tileMap:seek(tile)
		love.graphics.draw(tileMap, x * wTile, y * wTile)
	end
end

again, i'm simple, get confused, sorry.x

In 0.5.0, this can be achieved with the draws function.

Or are you playing with the 0.6.0 builds?

When I was working with 0.5.0, the editor I created saved tilemaps in the following format.

map = {}

map.tileset = love.graphics.newImage("Graphics/Tilesets/001.png", love.image_optimize)

map.tiles = {}

map.tiles.background = {}

-- // X-Pos, Y-Pos, X-Offset, Y-Offset, Width, Height, Passable (0/1).
map.tiles.background[1] = {16, 16, 0, 0, 32, 32, 0}
map.tiles.background[2] = {48, 16, 0, 0, 32, 32, 0}
map.tiles.background[3] = {80, 16, 0, 0, 32, 32, 0}
map.tiles.background[4] = {112, 16, 0, 0, 32, 32, 0}

The background layer was then drawn as follows.

-- Draw background tile layer.
for i,v in ipairs(map.tiles.background) do
love.graphics.draws(map.tileset, map.tiles.background[1], map.tiles.background[2], map.tiles.background[3], map.tiles.background[4], map.tiles.background[5], map.tiles.background[6])
if debug.grid == 1 then
if map.tiles.background[7] == 0 then
-- Passable tiles.
love.graphics.setColor(255, 255, 255)
love.graphics.rectangle(1, map.tiles.background[1]-16, map.tiles.background[2]-16, 32, 32)
elseif map.tiles.background[7] == 1 then
-- Impassable tiles.
love.graphics.setColor(255, 0, 0)
love.graphics.rectangle(1, map.tiles.background[i][1]-16, map.tiles.background[i][2]-16, 32, 32)
love.graphics.setColor(255, 255, 255)
end
end
end

Whilst this is quite possibly horribly inefficient, I was getting 700FPS on a full map with vsync disabled. Additional tile layers posed close to zero performance issues.

omg i missed that! should have known love would make it even easier
thanks avalon!

by the way, which editor were you using? ive tried Tiled but i cant seem to save as Lua. im guessing theres a plugin somewhere...?x

avalonmap.exe .

A tool I wrote to save it in the necessary format.
