end

function love.draw()

	love.graphics.drawq(character.player, quads[direction][iteration], character.x, character.y)

end	

I've already seen the similar post but did not understand where the problem lies
i use 0.8.0 version program in linux xubuntu
thanks for your understanding

I will not be very helpful, but you should update to the latest version of LÖVE, as you get an error for a function that doesn't exists anymore. You can now use love.graphics.draw instead of love.graphics.drawq.

[Ref]

You make them but you don't store them anywhere.
You need something like:

Code: Select all

quads = {}
quads[1] = love.graphics.newQuad(....
etc.

and then draw each of the quads.

thanks for your help try to include your example in my code
