Tower defense is a subgenre of strategy video game where the goal is to defend a player's territories or possessions by obstructing the enemy attackers, usually achieved by placing defensive structures on or along their path of attack. You have to create a Tower Defense Player on Unity.

We will send you a Unity project using version 2018 LTS (Long time support), with some prototype assets and some map/txt files. Your Tower Defense Player must use those maps as level descriptors. Game units must spawn on "start tile" and walk to reach the "end tile", the end. Towers will try to avoid units reaching the end by shooting at them. If a unit reaches the end the player will lose one live and the unit is removed from the map. The player starts with 20 lives, and Game Over is triggered when the player loses all lives. No input it’s gonna be needed from the user for the moment, so consider the entire system as a “fire and watch game”

Map file structure
Inside the project you will find map/txt files inside the Resources folder. The maps have this structure: A grid of values showing the map structure
#
Wave lines with number of enemies by enemy type

This is an example:

0000000200001000001
0000010300101020001
9000020300101011101
0000010300101010101
0000020001000010108
0000010300101020001
0000010300101020001
0000010300101020001
0000010300101020001
0000010300101020001
'#'
24 24

You can find two map files inside the unity project
Resources/map_1.txt
Resources/map_2.txt

Map interpretation:

Each cell in the map file can be interpreted as:

0: Path tile. This tile is walkable by units.
1: Obstacle tile. This tile is an obstacle and units must avoid them.
2: Tower defense 1. In this tile a Tower Defense Type 1 must appear. Units treat this tile as an obstacle.
3: Tower defense 2. In this tile a Tower Defense Type 2 must appear. Units treat this tile as an obstacle.
8: Start Tile. Units spawn in this point (Or as near as you can)
9: End Tile. Units target tile.

And every wave line as: xy
where
x is the number of units of type 1
y is the number of units of type 2

Elements behaviours:

This is the behaviour for the elements: Tower defense 1 is a bombing tower. It throws bombs targeting one unit but the bullet does area damage
Tower defense 2 is a freezing tower. It targets and affects one unit only. The affected unit will be frozen for 2 seconds reducing its speed by half
Unit of type 1. Standard unit. Walks default speed and has default resistance
Unit of type 2. Bigger unit. Walks slower than type 1 but has more resistance and makes bigger damage

To be Evaluated:

Smart use of Scriptable Objects
Memory management (Intense use of memory pools)
Code : Readability (Follow the code guide strictly)
Architecture
Avoidance of antipatterns
Balanced and responsible use of SINGLETONS (If you use them)
Object logic Composition (Balance between inheritance and composition)
Respect of SOLID principles in general.

Not needed: Art quality. We send you art (Prefabs and mock animation state machines) to work with you can create your own if you want but they will not be taken it into account.
