Hey i am making a game (first one) and i made a player class with image in it, and i want to add the player to the camera but getting an error, how do i manage to do it?
Player class:
local physics = require "physics" local Player = {} local Player\_mt = { \_\_index = Player } -- metatable local img physics.start() ------------------------------------------------- -- PRIVATE FUNCTIONS ------------------------------------------------- ------------------------------------------------- -- PUBLIC FUNCTIONS ------------------------------------------------- function Player.new( x, y) -- constructor img=display.newImage("crate.png") img.x = x img.y = y physics.addBody( img, { friction=1.0, density=1.0, bounce=0.3, radius=35 } ) img.isFixedRotation = true local newPlayer = { -- img=display.newImage("crate.png",100,100); x = x or 0, y = y or 0, } return setmetatable( newPlayer, Player\_mt ) end ------------------------------------------------- function Player:getX() return self.x end ------------------------------------------------- function Player:getY() return self.y end ------------------------------------------------- function Player:setX(x) self.x = x end function Player:setY(y) self.y = y end function Player:moveRight() self.x = self.x+2 img.x = self.x end function Player:moveLeft() self.x = self.x-2 img.x = self.x end function Player:Jump() img:applyForce( 0, -300, self.x, self.y ) end function Player:isJumping(ground) if img.y\>ground then self.x = img.x self.y = img.y return true else self.x = img.x self.y = img.y print("crate:"..img.x..","..img.y) print("player:"..self.x..","..self.y) return false end end ------------------------------------------------- return Player
