[Solved] quad spritesheet assistance

Post by walking_post » Mon Dec 26, 2011 5:33 am

Hi, new to love2d, and having a little trouble understanding using quads with a spritesheet. I can use love.graphics.draw to show the whole sheet, but quads don't show up.

Adjusted image in Gimp to 256x256 as per a post about non-2* image having trouble with some video cards (mine is a GT430, which shouldn't be a problem), and tried different file formats (png, jpg, bmp).

Probably an embarrassingly easy answer, but I'm stumped. Thanks!

you are doing it wrong

A) until you figure it out use no padding so your spritesheet looks like this

Image

B) the last 2 arguments of quad is not ever going to be 0,0 its the total size of your image

putting those two together ends up looking like

player = love.graphics.newQuad(0, 0, 55, 30, 111, 60)

which works fine to display the first quad

its startX,startY, width, height, total imageX, total image Y

have fun!

Wow, that's easier than what I was trying to do...lol. Thank you, osgeld! :)

quad = love.graphics.newQuad( x, y, width, height, sw, sh )
x, y = starting point of sprite
width, height = just the w/h of the sprite, not the x/y coordinates of the sprite's corner
sw, sh = total size of the spritesheet
