Have you ever been sick of writing - 1, 4, 1, 0, 0, 0, 0, 6, - to draw your levels. Because i am!
There has to be a simpler way.
How about using an image's colours for different blocks. A block-A pixel.
Can you please tell me how this is done so i can add it to my game Platformer X.

Another Kind of World does this.
Check out
world.lua and the
levels directory. Here's an excerpt from
world.lua:
Code: Select all
for x = 0, self.width-1 do
for y = 0, self.height-1 do
red, green, blue, alpha = self.baseImg:getPixel(x, y)
if red == 255 and green == 0 and blue == 0 then
love.graphics.draw(self.gfxNormal, x*8*self.scale, y*8*self.scale, 0, 3, 3)
elseif red == 0 and green == 255 and blue == 0 then
love.graphics.draw(self.gfxTop, x*8*self.scale, y*8*self.scale, 0, 3, 3)
elseif red == 255 and green == 255 and blue == 0 then
love.graphics.draw(self.gfxUnder, x*8*self.scale, y*8*self.scale, 0, 3, 3)
elseif red == 0 and green == 255 and blue == 255 then
...

There are tons of ways to solve this. I tend to create level editors in my games to get total control. Typically, I let the editor write automated lua code to files containing the data for each level.

well, i am currently using a system where i have a level .txt file that looks something like this:
111
101
111
(^that would be a box)
and it gets read into an array, where i use it in my game and in love.draw()
(love.draw renders the level)
if you want some code i can post some.
is this what you want?

Stabyourself.net's OrthoRobot does this fantastically. Not sure how... its open source though, just like Mari0
