Psp lua jump help

[saiyan x]

I am making a game and had lots of trouble with the player jumping but now jumping is fine except when u jump right or left. So here's my script and can anyone tell me why I cannot jump right or left properly.

Code: Select all

tilesize = 24
playerImage = Image.createEmpty(32, 32)
tileimg=Image.createEmpty(30, 30)
tileimg1=Image.createEmpty(30, 30)
white = Color.new(255,255,255)
red=Color.new(255,0,0)
blue=Color.new(0,255,0)
tileimg:clear(red)
tileimg1:clear(blue)
playerImage:clear(white)
tile = {tileimg, tileimg1}
player = {
 x = 40, y = 184, j=200, speedY = -2, speedX = 0, falling = 0,}
player.img = playerImage
screenwidth = 480-24
screenheight = 272-player.img:width()
world = {
 {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
