LÖVE

Hello world. I'm a novice programmer, but I've learned a lot using this framework. I've run into a bit of a problem, though:
The code is supposed to assign the mouse's x position to the variable mousex, and print its value when the RMB is held. It returns an error when I right-click: graphics.lua:1: bad argument #2 to 'print1' (number expected, got no value)
what do?

Code: Select all

function love.update()
	mousex, mousey = love.mouse.getPosition()
	if love.mouse.isDown("r") then
		love.graphics.print(mousex)
	end
end

1. Don't draw in love.update(), even if your function call was correct, it won't print it if you do the love.graphics.print in update. Unless you meant print(), which goes to console. print() works anywhere AFTER LOVE.LOAD() IS CALLED.
2. love.graphics.print takes at least 3 arguments: string, x, y.

Your error is simple: You're not allowed to use drawing functions anywhere except in love.draw(). After that, you can't forget to have coordinates for your printed text (they're the two parameters after the text you want to show).

EDIT) TechnoCat beat me to it. XP
