Question

that algoritmh is to make a cannon rotate over a plot...

var g = setInterval('rotateMe',speed)

function rotateMe()

{ x = |length| Math.cos(t)
y = |length| Math.sin(t)

plot = 'position:absolute; top:y; left:x'

document.getElementById('img').position = plot

t = t+angle of rotation
}

something went wrong with this algorithm need checker ^^

Answer 1

You'll have to do something like this. You're wanting to edit the style attribute:

document.getElementById('img').style.position = "absolute";
document.getElementById('img').style.top = y;
document.getElementById('img').style.left = x;

Answer 2

kk but its not the code only algorithm ^^
