Now the hardest part went. Everything else is easy..

Now let's answer what is screen wrapping?

Screen wrapping is when an image disappears one side and reemerges on the opposite side. That is what is called screen wrapping. ok

How do you do that in this arrow image... We need to add some codes functionka updateStageka();

open your Object.js file and let add some codes on updateStageka. Since our arrow image is running left to right we are going to add this
simple code..

function updateStageka()
{
window.requestAnimationFrame(updateStageka, canvaska);

arrow.x++;


if(arrow.x>canvaska.width)
{
arrow.x=0-arrow.width;
}


hadbaSawir();


}

Beautiful: Now what we said is simple. If the canvaska haduu dhaafo imageka. Then So gali the arrow image from the other side.

anagoo ku dhahnay

arrow.x=0-arrow.width;

Soo now let's watch what we did..here is the Demo

So now the image reappears again when it finishes the other end... Beautiful
