Dev Log Update 3
Got colliders working on a basic car as an obstacle and am able to show total damage dealt based on the parts of the car you've hit.
I then tried to get a count of how much snow you have to clean to win. So I added a collider on the path itself where you need to plow, set the isTrigger property and made it so that only the Snow Layer can collide with the Road Layer, but it wasn't registering the anything ontriggerenter...so a bit stuck there.. will look at it with fresh eyes tomorrow.
Tomorrow I'll also implement the timer to start the snow and if all goes well, I'll have a simple, 1 level game complete with horrible graphics lol
