We need to write something into those textboxes. What we'll do in this case is call an update method in HUD periodically, so that it can refresh the data and print it on the screen:
function HUD:update ()
local x, y = Character.prop:getScl ()We get the scale that we used to set the character's direction, and store it in a local variable
x:if x > 0 then self.leftRightIndicator:setString ( "Left" ) else self.leftRightIndicator:setString ( "Right" ) endIf you remember what we did before, this should be pretty clear. In order to turn right we scaled the character's
propto-1in thexaxis, and to1to turn the character to the left. So that's what we're doing here. If thexvalue of the scale is positive, then we're facing left. Otherwise, if it is-1, we're facing right. Then, depending on the case, we useMOAITextBox:setStringto update the string with the correct direction.x, y = Character.physics.body:getPosition () self.positionIndicator...
