UI that keeps track of score and player lives

2 types of carrot for stampeders (grazing animals) and meat for the predators that attack from the side

left click for carrot, right click for meat

predators cause a blood particle effect to appear then delete itself after 1 duration

both predators and stampede animals can be spawned in random sized groups or set to 1 each.

I didn't like how multiple animals would spawn in the same spot or within .5 units to either side causing massive clipping so my script creates a list of vectors from minX to maxX by 2 unit increments, 

Top row vectors are removed from the list when an animal spawns and the vector is added to a Vectorcooldown list with a corrisponding float list for the cooldowntime.  the float list is checked in update and every value in the list is reduced by deltaTime, when it reaches 0 its corrisponding index on the vectorCooldown list is removed and added back to the main spawn list.  

the side spawns are based on min/max z with 3 unit increments. they also had  their x value *= -1 to create a mirror point for the other side of the screen and both are added to the sidespawn list with a corrisponding quaternion to give the spawned predator an appropriate forward for it to follow the mirror quaternion.y *= -1 as well. Since there is much fewer side animals and they have a changing rotation requirements i just added the chosen vector and its mirror(no head on collisions from opposite sides) to a blacklist that each spawnRandomPoint checks if its on the list it rerolls until it finds a vector that isn't on the list then spawns the animal at that point and uses the corrisponding index of the quaternion list to set it rotation.

End results of this list stuff?  A much more organized and cleaner look IMO.
