I want to share this little code I wrote with you, it moves a selector over a vitual keyboard image:
def __init__(self):
self.keyboardMap = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', ' ', ',', '.', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', ' ', '"', '-', 'u', 'v', 'w', 'x', 'y', 'z', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', ' ', ' ', ' ']
self.lineTotal = 13
self.total = 65
self.offsetX = 0.06
self.offsetZ = 0.1
# the position where the letter 'a' is at your virtual keyboard image
self.startX = -0.849
self.startZ = 0.218
self.keyboardImg = Onscreenimage(image = 'keyboard.png', scale = (1,1,1), pos = (0,1,0), color = (1,1,1,1), parent = render2d))
self.keyboardImg.hide()
self.letterSelector = Onscreenimage(image = 'letterSelector.png', scale = (0.03,1,0.05), pos = (self.startX,1,self.startZ), color = (1,1,1,1), parent = render2d))
self.letterSelector.hide()
def open(self):
self.letterSelector.setPos(Vec3(self.startX,1,self.startZ))
self.letterSelector.show()
self.keyboardImg.show()
self.index = 0 # letter 'a'
self.accept('w', self.__moveSelector__, ['UP'])
self.accept('s', self.__moveSelector__, ['DOWN'])
self.accept('a', self.__moveSelector__, ['LEFT'])
self.accept('d', self.__moveSelector__, ['RIGHT'])
self.accept('enter', self.__getLetter__)
def exit(self):
self.letterSelector.hide()
self.keyboardImg.hide()
def __getLetter__(self):
self.selectedLetter = self.keyboardMap[self.index]
def __moveSelector__(self, direction):
if direction == 'UP':
self.index -= self.lineTotal # move one line up
# jump to the last line
if self.index < 0: self.index = self.total + self.index
elif direction == 'DOWN':
self.index += self.lineTotal # move one line down
# jump to the first line.
# self.total - 1 because self.index starts at 0
if self.index > (self.total - 1): self.index = self.index - self.total
elif direction == 'LEFT':
self.index -= 1 # move to the left
# moves the selector to the last character of the line
if self.index < 0: self.index += self.lineTotal
elif ((self.index + 1) % self.lineTotal) == 0:
self.index += self.lineTotal
elif direction == 'RIGHT':
self.index += 1 # move to the right
# moves the selector to the first character of the line
if self.index > (self.total - 1): self.index -= self.lineTotal
elif (self.index % self.lineTotal) == 0:
self.index -= self.lineTotal
self.letterSelectorZ = self.startZ - (self.offsetZ * (self.index / self.lineTotal))
self.letterSelectorX = self.startX + (self.offsetX * (self.index % self.lineTotal))
self.letterSelector.LerpPosInterval(0.2, (self.letterSelectorX,1,self.letterSelectorZ), (self.letterSelector.getX(),1,self.letterSelector.getZ()))
