Algodoo

Uses rotation for calculating the direction of velocity in x and y as cos rotation and sin rotation.
The acceleration is multiplying size of laser and fade distance minus distance of the laser and object divided by fade distance.

Graph may look buggy it is not realistic enough as shown here the laser is hitting the side of the box and the box is moving only up and down.

It took me time to make this laser after my idea because i didn't know how to make the code or thyme(?) for it.
