Image problems

[pgimeno]

Well, that's not too easy. I suggest you take a look at a skeletal animation library, like this one: https://love2d.org/forums/viewtopic.php?f=5&t=79607

Oh, I checked and yours worked perfect but I need a way to do it without adding the origin (7th and 8th) arguments to draw for body/image2.

Also, I only need minimal stuff. So really it's not that skeletal of an animation.

Then draw the hands by calculating the hook point manually.

Code: Select all

local body = love.graphics.newImage('0.png')
local hands = love.graphics.newImage('hands.png')
local nose = love.graphics.newImage('moleMask.png')

local a
love.mouse.setPosition(0, 0)
love.mouse.setPosition(400, 300)

function love.update(dt)
  local mx, my = love.mouse.getPosition()
  a = math.atan2(my - (100+body:getHeight()/2), mx - (100+body:getWidth()/2))
end

function love.draw()
  local bright = 0.8
  love.graphics.setColor(1*bright, 0.5*bright, 0.25*bright)

  love.graphics.draw(body, 100, 100,  0, 1, 1,  0, 0)
  love.graphics.setBlendMode("alpha", "premultiplied")
  love.graphics.draw(nose, 100-160/2, 100-256/2, 0, 1, 1, 0, 0)

  -- Add the centre of the body image to the hands
  love.graphics.draw(hands, 100+body:getWidth()/2, 100+body:getHeight()/2,
    a, 1, 1, hands:getWidth()/2, hands:getHeight()/2)

  love.graphics.setBlendMode("alpha", "alphamultiply")

  love.graphics.setColor(1, 1, 1)
end

function love.keypressed(k) return k == "escape" and love.event.quit() end

Thanks!

Also

Anything bad with "easy method". Does it reduce quality or slow down game?

??

Just wondering why you use "bright" at the beginning of love.draw?
edit: oh, dumb me, that's to make it brown.

Also wondering whether you think the images together ressembles some kind of mole

[pgimeno]

The nearest filter makes the rendering pixellated. For some that's a desirable property; it depends on your game. Generally I don't give artistic advice, so I can't tell whether it looks good or not in your case; try nearest and premultiplied alpha and see which one you like best. For the same reason I defer the second question to someone else.

Hmmm...okay. I see

Thanks! The thing works, though I just need to scale multiply the added width/height by the scale (if it's not 1).

Code: Select all

    local source = game:getAsset(self.source)
    
    vw = source:getWidth()/2
    vh = source:getHeight()/2
    
    local vww = self.parent.spriteImage:getWidth()/2 *self._w
    local vhh = self.parent.spriteImage:getHeight()/2 *self._h
    
    love.graphics.draw(source,self.x+vhh,self.y+vww,(angle or 0),self._w*flX,self._h,vw,vh)
