Text fading in and out?

[Ulqiorra]

I am working on a new VX script, my first in a long time, and I need to
be able to make a piece of text fade in and out.

I have the text drawn in a bitmap, which is held in a sprite.

Does anyone know how to do this?

All you need to do is adjust the .alpha of the bitmap.font.color and then refresh it, here I'll do a quick example...

def update

  c = self.bitmap.font.color

  @fade_out = false if c.alpha == 255 && @fade_out

  @fade_out = true  if c.alpha ==   0 && !@fade_out

  c.alpha += (@fade_out ? -1 : 1)

  self.bitmap.clear_rect(0, 0, 64, 32)

  self.bitmap.draw_text(0, 0, 64, 32, "Text")

  super

end

I didn't test it but something along those lines should work.

It doesn't work at all, actually.

I made this based off your code, but it doesn't work either:

[rgss] 
  def update_start
    @fade_out = false if @start.opacity == 255 && @fade_out
    @fade_out = true  if @start.opacity ==   0 && !@fade_out
    @start.opacity += (@fade_out ? -5 : 5)
  end

You can use the .opacity property of Sprite for making a fade in/fade out effect.
Example:

s = Sprite.new

s.bitmap = Bitmap.new(100, 32)

s.draw_text(0, 0, 100, 32, 'Example', 1)

s.opacity = 0

# Fade in

loop do

  Graphics.update

  s.opacity += 1

  break if s.opacity == 255

end

Graphics.wait(60) # Wait 1 sec

# Fade out

loop do

  Graphics.update

  s.opacity -= 1

  break if s.opacity == 0

end

s.bitmap.dispose

s.dispose

I did it!

My code is:

[rgss] 
  def update_start
    @fade_out = true if @start.opacity == 255
    @fade_out = false if @start.opacity == 50
    if @fade_out
      @start.opacity -= 5
    else
      @start.opacity += 5
    end
  end
