That was what I was trying to do the whole time but I don’t understand why the ball still goes through the ground and how to fix it
Try this.
function setup()
p_rect = physics.body(EDGE,vec2(0,0),vec2(WIDTH,0))
p_rect.x = 0
p_rect.y = 103
p_rect.type=STATIC
character = physics.body(CIRCLE,50)
character.x = WIDTH/2
character.y = 300
-- Start in the center of the screen
position = vec2( WIDTH/2, HEIGHT/2 )
-- Create two parameters to play with
parameter.number( "yCalibration", 0, 2.0, 0.6 )
parameter.number( "tiltStrength", 1, 40, 10 )
tab={ -- top 1=draw 0=no draw
{0,0,0,0,0,0,0,0,1,0},
{1,1,1,1,1,1,1,1,1,1}, -- bottom
}
end
function draw()
background(0, 145, 255, 255)
for x=1,#tab do
for y=1,#tab[1] do
if tab[x][y]==1 then
sprite("Platformer Art:Block Grass",y*70,(#tab+1-x)*70)
end
end
end
moveVec = vec2(Gravity.x, Gravity.y) + vec2( 0, yCalibration )
position = position + moveVec * tiltStrength
fill(255, 0, 0, 255)
ellipse( position.x, character.y, character.radius*2)
end
@magicskillz I didn’t like my above code, so I wrote this. It creates a physics object at each Sprite position making table changes easier.
EDIT: I also changed the way the character position is calculated.

@magicskillz Your indenting is so screwed up that you can’t see what goes with what. You have 2 function touched() inside of the draw function. You only need one function touched(), and it shouldn’t be within another function. You also have the function collide() within the draw function, again a no. You’re trying to use a class, but you don’t seem to know how to properly use it. You’ve been a member of the forum for a year, which means you should know basic programming by now. Every time I work on your code, I have to spend time reformatting it just to see what doesn’t line up or what doesn’t belong before I even execute you code.
Ok I’ll work on reformatting my work!
@magicskillz Maybe this will help you. Press the up arrow to jump. Press the left or right arrows to scroll the blocks left or right. Tilt the iPad to move the character left or right. If the character hits the spikes, he dies. Look at this code to see how I did things so you can add whatever else you want. Any questions, just ask. Also, look at the indenting to see how easy it is to understand what belongs to what.
EDIT: Code removed. A better version is below.
@magicskillz Here’s a better version. The character always stays in the middle of the screen. Tilt the iPad to move the background left or right. Tap the screen to jump. Landing on the spikes kills the character.

Thanks to the code @dave1707 provided I created this.
For some reason the background messed up when I took a photo
