• Player Stats:
• Special Note:
• Many of these stats have a BASE. This means the number that skill points modify. This is so I have the ability to adjust the BASE number to balance all entities at once, or adjust individual skill points to balance a single entity.
• Eg. base speed = 1, skill of 3 speed modifies base by +0.3 (now 1.3)
• Health:
• 1 Skill point = 10 health
• Eg. A player with health skill 4 has 40 health
• This determines how many times the player/enemy can be hit and works directly with the attack skill of the attacker.

• Attack
• This determines how much health the attacker takes away from the receiver
• 1 skill point = 10 damage
• If an attacker has an attack of 10, then 10 health is removed from the total.
• Defence
• This is a modifier for the damaged received, and directly affects the attack skill of the attacker
• 1 skill point = 5% reduction in damage taken
• Eg. A player with a defence skill of 70, fighting an enemy with the attack skill of 3, receives 30 damage with a 35% reduction. Player now receives 19.5 damage    
• Haste (dexterity)
• This is the attack speed of entities, or how often they may initiate the attack animation.
• BASE = 0.9 seconds. (standard time to complete animation sequence)
• 1 = 180% of BASE                 2 = 160% of BASE
• 3 = 140% of BASE 4 = 120% of BASE
• 5 = 100% of BASE 6 = 80% of BASE
• 7 = 60% of BASE 8 = 40% of BASE
• 9 = 20% of BASE 10 = 0% of BASE (nothing has this)
• Eg. base animation time is 0.9 seconds, A player with a Haste skill of 3 completes the animation at 140% of the base time (now 1.26 seconds)
• Speed (mobility)
• This is the speed at which entities move about the map, it also affects the sprinting length and jumping height.
• BASE speed = 1 (enemy’s speed)
• Since the player must move relative to the enemy, the enemy always moves at BASE speed
• Each skill point adds +0.1 to the BASE speed
• Eg A player with speed skill 4, travels at 1.4x BASE speed
• Jump Height
• Affects the height at which the player may jump
• 1 skill point = 1 BASE Jump height (recommended small)
• I will be making the map with tiers of flat space, 1, 2, 3 and 4 levels high. A player cannot jump more than 1 full tier at once. Each tier is 10 times that of base in height
• Eg. Base = 1, So a player with a speed skill of 4 may jump 4 times Base, Which is 40% of the total height of 1 tier. This allows me to make jumping shortcuts throughout the map.
• Sprinting Length
• Affects the length of time a player may sprint for
• BASE = 1 Second
• 1 skill point = 1 second
• Eg. A player with the speed skill of 5 may sprint for 5 seconds
• Sprinting is always 2x that of their movement speed.
• Eg a player with speed skill 5, moves at 1.5x BASE, and may sprint for 3x BASE for 5 seconds
• Once a player has finished sprinting, a player may not activate sprint again for 25 seconds

• Player Gameplay
• Combat
• Has health based on Health sill (see health)
• Has a specified attack range in front of player (recommended 2 seconds worth of walking distance)
• Does attack Damage based on attack skill (see Attack)
• Attack may hit all enemies within range (recommended small area at max range where it is possible for all inside to take damage
• Attack speed based on Haste skill (see Haste)
• Movement
• Moves at speed related to skill level (see Speed)
• Can dodge backward, and side to side (reccomended similar distance as range of attack)
• Can jump specified height based on speed skill (see Jump)
• May sprint at double their final movement speed (see Sprint)
• Spawn
• Player Spawns at safe space (will be a specific spot for this on the map)
• Death/Faint
• Player has a total of 3 lives (3rd death is gameover)
• Upon losing all health a life is lost
• Dying (losing a life) Results in a respawn at the safe space

• Lane Enemies Gameplay
• Combat
• Has health based on Health sill (see health)
• Has a specified attack range in front of entity (recommended small, melee range)
• Does attack Damage based on attack skill (see Attack)
• Attack speed based on Haste skill (see Haste)
• Movement
• Upon spawn, always follow set path toward tower
• If player in range, attack player
• If player leaves range, head back to tower
• If 3 entities are already in range, continue to tower  
• Moves at speed related to skill level (see Speed) (always BASE)
• May not jump
• May not sprint
• Spawn
• Spawn at one of 3 predefined spaces on the map
• Spawn at regular intervals
• Base rate of spawn changes based on infection level (see Infection)
• Each spawn is randomised between all 3 points (to reduce patterns)
• Death/Faint
• Play death animation, fade out/disappear

• Node Enemies Gameplay
• Combat
• Has health based on Health skill (see health)
• Has a specified attack range in front of entity (recommended small, melee range)
• Does attack Damage based on attack skill (see Attack)
• Attack speed based on Haste skill (see Haste)
• Movement
• Remain Idle until player in range of node point
• Return to Idle if Player leaves range of node point
• If player in range, attack player
• Moves at speed related to skill level (see Speed) (always BASE)
• May not jump
• May not sprint
• Spawn
• Spawn in predefined node spaces when a node becomes infected (See nodes)
• Death/Faint
• Play death animation, fade out/disappear

• Tower Gameplay
• General
• Takes 1 damage per entity hit
• Recommended 250 health (250 hits)
• Output health as a percentage on HUD
• If heath depleted, gameover

• Nodes
• General
• 5 Nodes total
• Located at predefined spaces on the map
• Each node has range covering the nearby area
• Number of nodes held by each team displayed on HUD
• Node enemies spawn immediately upon infection (animation?)
• New Game
• Player Controls 2 Nodes
• Enemy Controls 3 Nodes
• Becoming Infected
• Nodes have a chance to become infected at regular timed intervals (recommended 78s)
• A cleared nodes have a 33% chance of becoming infected every 78s
• Each node has its own timer
• Timer begins/resets when a player leaves node range, creating an element of randomness to infections
• Already infected Nodes are not considered for reinfection
• Upon infection, display notification on screen
• Upon clear, Display notification on screen

• Infection Rate
• A score system based on how many Nodes the player controls
• Infection rate total = 100
• New Game Infection rate begins at 60
• If the player owns more, score increase
• If the enemy owns more, score decrease
• Scoring
• Calculated by the difference between captured nodes
• Eg. player owns 2, enemy owns 3. (2v3 is a difference of 1)
• Score is updated every 2 seconds
• add/subtract the points difference from infection rate
• Eg. player owns 2 and enemy owns 3. Count is 2v3 with a difference of 1 in enemy favor. Every 2 seconds score updates with -1 score
• Spawn Rate Increase/decrease
• Infection score directly affects spawn rate
• Every 1 point (out of 100) is equal to 0.10 seconds.
• Spawn rate is calculated by the score the player does not have
• Eg. The current infection Rate is 55/100. This means the player has 55 points, and the enemy has 45 points. The spawn rate is 0.10 seconds x the enemies points. In this case the spawn rate becomes 4.5 seconds, So every 4.5 seconds a lane enemy is spawned
