Point-n-click

[Codein]

I have provided the point-n-click movement system I am using on Noctorious. Now, you may be thinking "Yes, this has been done" but I wanted to provide a version that wasn't as complex as Mallard's system for those who haven't the skill or knowledge to hack his system.

This system moves the player at a static speed, rather than taking
acceleration into account, thus acting as an intermediate solution between classic static-speed arrowkey movement and Mallard's point-n-click movement system.

Not only that, but I'd say it'd be slightly easier to learn from this system if you're new-ish to the GScript language.

The collision detection isn't the greatest, however, I've managed to get the player pretty flush against walls.
