Repeating an image?

[Sullinger]

How would you get a specific tile to repeat itself to fill up the entire screen?

Use

Code: Select all

image:setWrap('repeat','repeat')

See here: https://love2d.org/wiki/%28Image%29:setWrap

And then draw the image with a quad, that is larger than the image.

Code: Select all

quad = love.graphics.newQuad( 0, 0, largeWidth, largeHeight, imageWidth, imageHeight )
love.graphics.drawq( image, quad, x, y, ...)

This, however, only works, if there is only this one tile in your image. If you have a tile sheet, you have to come up with a different solution. For example a for-loop.

hmmm.... I keep trying it, but it either doesn't do anything or I get an error. And yes, my image is in PO2. (sorry, I'm a noob, haha)

I would go about this with a for loop something like this (Note, this is psuedo code)

Code: Select all

for w = 0, screen_width/tile:width() do
for h = 0, screen_height/tile:height() do
screen:blit(w * tile:width, h * tile:height(), tile_image)
end
end

This method turns the screen into a grid that is tile:widthXtile:height big and fills each place on the grid with the tile that we want to loop.
Or, a faster method would be to draw all of those onto a canvas then simply blit the canvas (1 graphics card call vs. a few hundred to over a thousand).

I'm not sure if Love has a simpler way to do this.

Not that I know of! But I wrote this up for you because I actually know how to do this one. It's a pretty thorough explanation of the process and everything. Hope it helps you out, dude!

Just in case you are too lazy to find an image to wrap, here.

P.S. Put the main.lua and the image you want to wrap (name it "imageToWrap.jpg", or change the file you want to load by changing the code.. your call) in the same folder. Badabing, LOVE magic!

It took me less then a minute to type... Is it really that bad?

Tell me, is wrap faster than spritebatch? I am using the following code:

Code: Select all

grass = love.graphics.newImage("grass.png")
batch = love.graphics.newSpriteBatch(grass, 2000)
for x = 0, 40 do
	for y = 0, 40 do
		batch:add(x * 256, y * 256)
	end
end

256x256 is the size of the tile. I create it once and then just draw the "batch" object.
