If I want to draw something to a canvas, do I need to put the draw functions to draw something on to the canvas in the love.draw function? And how do I draw something to a canvas?

When you draw stuff between the "set" and "unset" steps, everything you draw ends up on the canvas.

To actually answer part of your question, unlike drawing to the screen (more or less) directly, you can render stuff to a canvas outside of love.draw... but unless you're just pre-rendering some static stuff, i'd (erase, and) draw to canvases in love.draw too.

Code: Select all

-- create a canvas somewhere outside love.draw
local myCanvas = love.graphics..newCanvas ( width, height, {format="normal"}, 1 )

-- set the canvas inside love.draw, and clear its contents if need be
love.graphics.setCanvas ( myCanvas )
love.graphics.clear()

-- draw things to canvas with love.graphics.draw, love.graphics.rectangle, or other methods here

-- unset the canvas
love.graphics.setCanvas()

-- draw the canvas to screen
love.graphics.draw ( myCanvas, x, y, rotation, scaleX, scaleY )

When you draw stuff between the "set" and "unset" steps, everything you draw ends up on the canvas.

I have seen your code but why do things get discoloured?

Because you forgot to setColor(1,1,1) before drawing the canvas to the screen; the graphics state remembers the last set color, and if you're not careful, it can tint things you don't want tinted.
