Custom Mouse Cursors (Tutorial)

[BlackBulletIV]

As I recently had to customise the mouse cursor for my new prototype, I thought I'd write a tutorial on the subject. Here it is:

Custom Cursors in Love2D

I would add a sentence explaining that it's better to draw the image using a '0, 0' (top-left) origin if you want a traditional mouse pointer and not a crosshair.

I'm disappointed! You even't implemented normal/clicking states in your tutorial? That's bellow your usual quality! ;D

Good point.

Huh? I've no idea what you mean. If you've talking about keeping track of clicking and the like, that's going beyond the intended scope of this tutorial.

Since your tutorial was about teach how to use custom mouse cursors, I would think that fits in your intended scope of tutorial also cover custom "mouse states". As you guess something (quickly imagined) like this:

Code: Select all

function love.load()
  cursor_off = love.graphics.newImage("crosshair_off.png")
  cursor_on = love.graphics.newImage("crosshair_on.png") 
  cursor = cursor_off
  love.mouse.setVisible(false)
  love.mouse.setGrab(true)
end

function love.mousepressed(x, y, button)
   if button == 'l' then cursor = cursor_on end
end

function love.mousereleased(x, y, button)
   if button == 'l' then cursor = cursor_off end
end
-- or other better way of swap cursor of course
function love.draw()
  love.graphics.draw(cursor, love.mouse.getX() - cursor:getWidth() / 2, love.mouse.getY() - cursor:getHeight() / 2)
end

Ah but never mind! It's your tutorial and was only a silly provocation/suggestion.

It's also worth taking note that it may lag on some systems, and you want to offer an option to disable vsync!

@coffee: Ah I see. I might just add that.
@josefnpat: Another good point. Though with all things I should add, I'll have to structure the tutorial a bit different I think.

For some strange reason, the wiki page I created for this tutorial isn't appearing in the tutorials category. And yeah, I've purged the tutorials page multiple times. Anyone know what's going on?
