Help with physics bodies

Questions
1

For some reason, this code isn’t working. It’s updating the player velocity, but it only changes the x by 2 then sets it back to 374. Also, the physics body is constantly moving up, and its not event redrawing the character sprite at the right place. To add to that, I can’t even set the physics body x and y in the setup, it just sets it to 374, 374. Please help!

function setup()
parameter.watch(PlayerY)
displayMode(FULLSCREEN_NO_BUTTONS)
supportedOrientations(LANDSCAPE_ANY)
floor1 = physics.body(EDGE,vec2(400,HEIGHT/2),vec2(600,HEIGHT/2))
Player = physics.body(CIRCLE,50)
physics.gravity(0,300)
parameter.watch(“PlayerX”)
parameter.watch(“PlayerY”)
floor1.linearVelocity = vec2(-200,0)
Scene = 1
scrollTitleScreen = 0
xVel = 0
yVel = 0
end

function draw()

--Draws the appropritate stagese

about putting all code in alignment so they do not show a distinct part to another. :slight_smile:

Or use pastebin.com

Not sure what this is supposed to do, but I modified some of the code. See comments that I added to certain lines. I think I commented all the lines I modified.

Thanks! It works now.
