Tree generation from quads.

[Ryne]

So, I have these trees generating as I want them to, the only issue is that it's with single images and the code is kind of ugly and not really universal.

This is what I have

http://d.pr/YZYR

Basically I have a tile grid of all 0's, and any tile that is a 1 has this tree drawn on it.

Code: Select all

function drawTrees()

	for i = 1, #map do
		for l = 1, #map do
			if map[i][l] == 1 then
			love.graphics.draw(images.treetest, mapToWorld(l-1, i-2))
			end
		end
	end

end

now this works fine for just one tree, but now I have a quad for my tree tile set.

Code: Select all

	quads = {
		love.graphics.newQuad(0, 0, 16, 16, 64, 64), -- big white
		love.graphics.newQuad(32, 0, 16, 16, 64, 64), -- big green
		love.graphics.newQuad(32, 32, 16, 16, 64, 64), -- big blue
		love.graphics.newQuad(0, 32, 16, 16, 64, 64), -- big orange
		love.graphics.newQuad(0, 16, 16, 16, 64, 64), -- med white
		love.graphics.newQuad(0, 48, 16, 16, 64, 64), -- med orange
		love.graphics.newQuad(32, 48, 16, 16, 64, 64), -- med blue
		love.graphics.newQuad(32, 16, 16, 16, 64, 64), -- med green
		love.graphics.newQuad(16, 0, 16, 16, 64, 64), -- 2 white
		love.graphics.newQuad(16, 32, 16, 16, 64, 64), -- 2 orange
		love.graphics.newQuad(48, 0, 16, 16, 64, 64), -- 2 green
		love.graphics.newQuad(48, 32, 16, 16, 64, 64), -- 2 blue
		love.graphics.newQuad(16, 16, 16, 16, 64, 64), -- single white
		love.graphics.newQuad(16, 48, 16, 16, 64, 64), -- single orange
		love.graphics.newQuad(48, 16, 16, 16, 64, 64), -- single green
		love.graphics.newQuad(48, 48, 16, 16, 64, 64) -- single blue
	}

So, It would be great to be able to specify numbers as trees or other objects. Similar to how I have "1" as that single orange tree, except with ALL of the trees. you know?

As always, any help is appreciated. Thanks guys!

Something like this?

Code: Select all

function drawTrees()

   for i = 1, #map do
      for l = 1, #map do
         if map[i][l] ~= 0 then
         love.graphics.drawq(images.treetest, quads[map[i][l]], mapToWorld(l-1, i-2))
         end
      end
   end

end

Hi there!

I explain how to do that on my tile tutorial.

If you are in a hurry, read just part 1b, in which I do exactly that. You might want to also read 1c (the next one). It will save you some typing.

      end
   end

end

Now I feel dumb, though yeah it worked great. Thanks Robin

No problem, mate.
