Software Engineering Tower Defense

a. Towers

1. The tower sizes are as follows:

Tower type Size Cost Basic 1x1 250 vermeerium

Freeze 1x1 300 vermeerium Fire 1x1 300 vermeerium

Mortar 1x1 400 vermeerium Pulse 1x1 500 vermeerium

1. Descriptions: There will now be names associated with all of the towers in the interface:

a) Basic tower:

(1) GAU-81A “Avenger”

(2) 30mm Hydraulically-Driven Seven-Barreled Gatling-Type Rotary Cannon (basic gun tower)

b) Fire tower

(1) HPNC-61 “Dragon’s Breath”

(2) High Pressure Napalm Cannon (once placed, it will fire a steady stream of fire in one direction the player may choose, radius will be a cone shape in the direction the player placed the tower)

c) Freeze Tower

(1) LNCC “Ice Box”

(2) Liquid Nitrogen Cryogenic Cannon (hits everything in its radius. Fires every second regardless of whether there is an enemy within its radius)

d) Mortar Tower

(1) LRHODS-27 “Hot Rod”

(2) Long Range Heavy Ordinance Delivery System (very high power, slow firing, single shot tower)

e) Pulse Tower

(1) EMPCS “Sparky”

(1) Electromagnetic Pulse Charging Station (hits everything in the radius. Fires every five seconds regardless of whether there is an enemy within its radius)

2. These are the statistics for each tower, including type, damage, range, fire rate, cost, and the effect to enemies.

Damage from base 25% Tower

Purchase Price 2 (1st Tree) 50% Increase in

Damage from base 50% Tower

Purchase Price 3 (1st Tree) 100% Increase in

Damage from base 100% Tower

Purchase Price 1 (2nd Tree) +1 Unit of Radius* 25% Tower

Purchase Price 2 (2nd Tree) +1 Unit of Radius* 50% Tower

Purchase Price 3 (2nd Tree) +1 Unit of Radius* 100% Tower

Purchase

*This means +1 Unit of Radius from the center of the tower

4. Tower info panel – when a tower is either hovered over in the store or clicked after it is placed it will display the tower info panel which includes: a) Tower name b) Tower damage c) Tower rate of fire d) Tower current sell price e) Tower upgrade radius button (button will include

price of upgrade and current upgrade rank f) Tower upgrade damage button(button will include

price of upgrade and current upgrade rank) g) Tower sell button h) Tower avatar

Test Cases:

The objective of this project is to employ software engineering techniques from the classroom to build a quality tower defense game in a real life setting. The project follows the software life cycle, specifically the spiral paradigm, to gather requirements, design a viable solution, code into usable software, and mitigate errors through standardized test practices. Through this process, a game was created that has been built to customer requirements and software engineering standards.
