Platformer Help/Maybe a tutorial?
Posted: Wed Dec 10, 2014 1:20 am
So I've been working on a small platformer from a tutorial I found online. The guy doing the tut left the tutorial before implementing jumping, so I tried to make my own code for it. Long story short, this is screwed up and I need some help. It should be really simple, but this is my first time using Lua (or programming in general) in a while. 
Here's all the code from my player.lua file and my main.lua file. Thanks!

--main.lua
require "player"
function love.load()

groundLevel = 600
gravity = 900
--Loading Classes
player.load()
end
function love.update(dt)
UPDATE_PLAYER(dt)
end
function love.draw()
DRAW_PLAYER()

love.graphics.setColor(168, 72, 72)
love.graphics.rectangle("fill",player.x,player.y,player.width,player.height)
end
function player.physics(dt)
player.x = player.x + player.xvel * dt
player.y = player.y + player.yvel * dt
player.xvel = player.xvel * (1 - math.min(dt*player.friction, 1))
if not(love.keyboard.isDown('w')) then
player.yvel = player.yvel + gravity * dt
end
end
function player.move(dt)
if love.keyboard.isDown('d') and
player.xvel < player.speed then
player.xvel = player.xvel + player.speed * dt

player.xvel > -player.speed then
player.xvel = player.xvel - player.speed * dt
end
if love.keyboard.isDown('w') and
player.yvel == 0 then
player.yvel = -player.jumpHeight * dt
