Health Bar (partially) Fixed

The problem with the healthbar before is that when the health would be reduced, the health bar would disappear from the screen. To look into this bug, I created a GUIText that would print the health to the screen. Sure enough, the health went down to the current value but the health bar still disappeared. I then printed the value of the healthbar width to the screen, and when health decreased, the width value went from 225 to 0.

I printed the formula (health / maxHealth) to the GUIText next, which went from a value of 1 to 0. From this, I could tell that the problem was caused by this conversion. By changing the type of health and maxHealth from integers to floats, this solved the problem.

I have also changed the health system so that instead of health decreasing passing through a waypoint, that colliding with a tree deduces it instead. However, I was unable to implement it so that every tree in the track reduces damage (since they are not gameobjects) but I have placed one tree in the track (tree sticking out on inside of first corner) since this tree is a gameobject.
