VXA Draw Text Test 2.0

# Text Tester
# By Mithran

# change the options at the top of the script to test various text drawing
# situations

# while in the tester:

# q/w add/subtract string width
# a/s add/subtract buffer width
# Enter: Center bitmap
# left/right scroll bitmap left/right, hold ctrl for faster scroll

  Font.default_name = "Verdana" # for comparison to VX
  Font.default_size = 20 # for comparison to VX
  #Font.default_outline = true
  #Font.default_italic = true
  #Font.default_shadow = true
  #Font.default_bold = true

class Scene_DrawTextTest < Scene_Base
  ON = true # change to false to disable this text tester
  TEST_TEXT = "The quick brown fox jumps over the lazy dog, and lands in a fox trap?!"
  "The green area is the rect given by Bitmap#text_size."  +
  "  And this is just an extra optional line that can be added to the above to demonstrate the error."
  # the green area is the rect given by Bitmap#text_size for the above string,
  # and the text is drawn to this rect
  # by definition, the text should be of approximately the same size as the rect
  # and should not shift if alignment is changed, but neither is true

  # if you make the above string really long (as in, for horizonally scrolling text)
  # the draw text will collapse over itself (uncomment the plus to see)
  ALIGN = 0# text_size issue is really ovbious when aligned left
  # but try center with longer text, to show text drawing over itself for no reason
  # to make matters worse, it doesnt even properly center when this happens

  BUFFER = 0 # how much wider the bitmap is than the text drawn to it
