So you know how half of the sprite sheet is shared with the map? Because of that, usually I use the half for the map, one spritesheet tab for sprites, and one tab for map tiles. Well, I just figured out that in doing so I dont use 1/4th of the tile data. This program I made uses the 1/4th tile data to flip the map tile. I will be making a tool to use this easily soon.
Code to import:
function _map(x,y,sx,sy,celw,celh,layer)
local x=x
local y=y
local celw=celw
local celh=celh
local layer=layer --not used yet
if x==nil then
x=0
end
if y==nil then
y=0
end
local sx=x
local sy=y
if celw==nil then
celw=16
end
if celh==nil then
celh=16
end
for i=0,celw*celh do
tile=mget(x,y)
if tile<64 then
--first tab
flipx=false
flipy=false
tile+=64
elseif tile>63 and tile<128 then
--second tab
flipx=true
flipy=false
elseif tile>127 and tile<192 then
--third tab
flipx=false
flipy=true
tile-=64
else
--fourth tab
flipx=true
flipy=true
tile-=128
end
spr(tile,x*8,y*8,1,1,flipx,flipy)
x+=1
if x==sx+16 then
x=0
y+=1
end
end
end |
The code uses the 2nd spritesheet tab for the tiles.
Call _map() whenever you want to use the function in your game.
