Tracking Objects or Adding Styles

General
1

I have a circle physics object and I wanted to know if there was any way to add a bulging effect so that it would look like a sphere? If not, is there any way to track a sprite of a sphere onto a physics object

Not sure about the bulging effect but you can just add the sprite using the circles location. For a demonstration add the following to the physics debug draw class in the physics demo at line 100

      sprite("Small World:Heart Glow",0,0,2*body.radius)
3

can’t get the heart to show? What test number?

4

In the physicsdebugdraw class. Not in any of the tests. When you run, test1 contains a circle so should show

5

Or taking the demo by @Rob10 from and swapping the ellipse for a sprite (original thread http://twolivesleft.com/Codea/Talk/discussion/comment/11440#Comment_11440)

    ball.x = WIDTH/2
    ball.y = HEIGHT/2
    ball.sleepingAllowed = false

    wall1 = physics.body(EDGE,vec2(0,0),vec2(0,HEIGHT))
    wall2 = physics.body(EDGE,vec2(0,0),vec2(WIDTH,0))
    wall3 = physics.body(EDGE,vec2(WIDTH,0),vec2(WIDTH,HEIGHT))
    wall4 = physics.body(EDGE,vec2(WIDTH,HEIGHT),vec2(0,HEIGHT))
    wall1.type = STATIC
    wall2.type = STATIC

    wall1.restitution = .1
    wall2.restitution = .1

    wall4.restitution = .1
end

-- This function gets called once every frame

    physics.gravity(Gravity)
    ball.gravityScale = GravityScale
    ball.restitution = Restitution
    background(40, 40, 50)

    fill(255, 255, 0, 255)
    --ellipse(ball.x,ball.y,ball.radius*2)
    sprite("Small World:Heart Glow",ball.x,ball.y,ball.radius*2)

@West ok thanks it worked. Now I need to find a pinball sprite
