[SOLVED] setCanvas() expects a number argument?

[NetherGranite]

I'm getting this error:

Code: Select all

main.lua:346: bad argument #2 to 'setCanvas' (number expected, got no value)

What number am I supposed to be giving it?

Trying to pass 0 to it gives me this error:

Code: Select all

main.lua:346: Invalid slice index: 0.

To clarify, this is love.graphics.setCanvas(canvas1, canvas2, …) that I'm trying to call.

Works for me.

Code: Select all

local canvas1 = love.graphics.newCanvas()
local canvas2 = love.graphics.newCanvas()
love.graphics.setCanvas(canvas1, canvas2)
love.graphics.setCanvas()

You'll need to provide more information.

If the canvas is an array texture or cubemap or 3D texture, you need to give it a layer/cube index to render to as an argument in setCanvas.

It turns out this happens if you try to pass three numbers to newCanvas(), e.g. love.graphics.newCanvas(1920, 1080, 5). This is because the third argument is how many layers the canvas should have; as a result, setCanvas() now expects a number argument telling it which layer of the canvas to use.

I should add the disclaimer that this is my best guess since such behavior is undocumented as of writing this. I have bought up this lack of documentation in this post.
